Upgrade iMac to up to 8TB Internally!

Anyone looking to maintain that all-in-one feel of the iMac has gotta love 8TB internally.

This is not a job I’d take on myself (complexity the upgrade process), but OWC offers a service to perform the upgrade (see hilited note).

Other World Computing Announces Apple iMac Hard Drive Upgrades Now Extend to 8.0TB

Apple iMac owners can now increase their storage capacity to 8.0TB while maintaining system fan and diagnostic performance

WOODSTOCK, IL – May 27, 2015 – Other World Computing (OWC), a leading zero emissions Mac and PC technology company, announced today that Apple iMac owners can now upgrade their iMac to 8.0TB of storage while maintaining correct system fan control with the OWC in-line digital thermal sensor. The new drive option, one of many upgrade options for the iMac from OWC, extends the iMac upgrade path and provides increased storage capacity with 23 percent lower energy consumption.

OWC Upgrade Kits - Increase Storage Capacity with Confidence

OWC upgrade kits for Apple iMac computers provide the tools and equipment required to install a new hard drive or solid state drive in an iMac. All OWC drive upgrade kits for iMac computers include a 14-piece toolkit, two suction cups for outer glass removal and a microfiber cleaning cloth. Solid state drive upgrade kits include a SATA data cable and an SSD power cable.

OWC hard drive upgrade kits include the OWC In-line Digital Thermal Sensor, which works though the iMac System Management Controller to eliminate excessive fan noise and maintain proper system fan control. This innovative device is designed specifically for the iMac, requires no software hacks and is designed to be compatible with Apple's built-in diagnostic processes.

The OWC 8.0TB iMac upgrade option utilizes the HGST 8.0TB Ultrastar® He8 hard disk drive. The drive is sealed with helium inside rather than air, which leads to 23 percent less power consumption than air drives. The HGST drive comes with a five-year warranty and usually ships on the same day as ordered.

"We're excited our Apple iMac upgrade options now extend to 8.0TB of capacity while also maintaining proper performance of the iMac cooling fan," said Larry O'Connor, Founder and CEO, Other World Computing. "The drive provides a large amount of storage capacity while running cooler and quieter than competing hard disk drives. We believe this new drive option will enable iMac owners to further extend the usability of their computers."

Availability and Pricing

OWC drive upgrade kits for Apple iMac computers are available immediately with prices starting at $39.00. Various disk drive options are available and are sold separately from the upgrade kit.

While OWC encourages the do-it-yourself philosophy, this can be a difficult upgrade that requires advanced skills. Customers who are not fully confident in their ability to upgrade their drive can have OWC upgrade their iMac where our certified technicians will expertly complete the upgrade for the customer. Upgrades are usually completed and shipped back to customers within 1-3 weekdays. The total time for the entire upgrade process, including transit time, is dependent upon customer location and the shipping methods chosen.

OS X Yosemite May Drop Unstable 'discoveryd' and Restore mDNSResponder

This is good news if the final version of OS X 10.10.4 ships without the troubled discoveryd.

The 'discoveryd' problems have cause usability misery for some users.

I’ve had my own inexplicable and disturbing network failures which require disabling networking, then re-enabling it—even as the same local LAN has no issue at all on a 2nd machine. Maybe it’s discoveryd, maybe not but I’m hoping. And then there is the Pathological Network Performance in Apple OS X issue, but I don’t expect Apple to fix that one.

Now if only Apple can get more adults in charge for OS X, things might start looking up on Apple Core Rot.

Apple Photos: Nuisance Behavior by Design

I shoot about ten different types of cameras a year, dozens of lenses of various brands, and about a dozen different Compact Flash and SDXC cards.

Each and every time I insert a card into the card reader, Apple Photos pops up. There is no preference in Photos to disable this nuisance. And since Apple Photos is dreck as far as any professional use (and an unacceptable risk to any professional workflow that must be dependable over time), it’s a nuisance I’d really like to get rid of. So here is one way to do that.

Image Capture:
disable launching app for card/camera

An alleged workaround is to open Image Capture (why not Photos itself?!), select the card icon, and using a tiny little control set it to “No Action” upon card insertion. This must be done for *every* camera card.

But this setting is destroyed every time the card is formatted in the camera. Since I do that every time I start a new photo job, this is no fix at all, just a make-work waste of time with no benefit.

To Apple Core Rot and the Apple bugs that never get fixed that waste my time each and every day, add the arrogance of presuming everyone wants to import images into Apple Photos, assuming that everyone possesses only one camera or camera card that is never formatted, and the conceptually vacant design thinking of not allowing a simple checkbox setting to disable the behavior.

Update: I finally just followed my own advice and removed Photos.app. Headache removed.

RAID-5 Can Partitioned

Several readers have emailed to ask whether RAID-5 or RAID-4 can be partitioned into multiple volumes. Indeed it can:

RAID-5 or RAID-4 Can be Partitioned to Suit

Note that OWC offers a RAID-5 edition of the Thunderbay, which comes with SoftRAID 5 included. The MPG recommendation for most users is to NOT use one large 12/15/18TB volume, but to “chunk” it (partition it) into 4/5/6TB volumes that thus match the 4/5/6TB capacity of single-drive external backup volumes. This has the operational advantage of simplicity when cloning.

OWC Memory Kit for new iMac 5K

MPG has used OWC memory (and SSDs) exlusively in all its Macs for the past six years.

Even Apple has OWC memory—I (Lloyd) know—because by accident I returned the iMac 5K last year with 32GB of OWC memory and never got it back! :;

Save $300 on memory: Apple wants $600 to go from 8GB to 32GB, but the OWC 32GB memory kit for iMac 5K is only $300. Installation is super easy.

OWC Announces Availability of Memory and Drive Upgrades for Latest Apple iMac with Retina 5K Display, Memory Savings of up to $300 vs. Factory

Tuesday, May 19th, 2015

Other World Computing announced today the immediate availability of the OWC Memory Upgrade Kits with up to 32GB for the new configuration of the Apple iMac 27″ with Retina 5K display.

The new iMac configuration comes with a 3.3GHz quad-core Intel Core i5 processor, 8GB of memory, a 1TB hard drive and a 5K Retina display, for a price of $1,999.00. OWC offers memory upgrade kits of 8GB, 16GB, or 32GB, which offer savings up to $300 over comparable factory options. Like all OWC memory upgrade kits, a ‘how-to’ install video and OWC lifetime limited warranty are included.

One of the Easiest Upgrades for Your iMac

Just like the original iMac model, a memory access panel on the rear of the newly announced iMac ejects via a simple push button located above the power input. Adding more memory is fast and simply involves installing new modules into the memory slots and reinstalling the access panel. Mac performance experts recommend selecting the least amount of factory installed RAM when ordering any iMac, taking advantage of significant cost savings by choosing OWC memory.

Savings up to $300 Compared to Factory Upgrade

New iMac owners seeking to max-out their RAM can select the 32GB OWC memory upgrade from OWC and save $300 compared to the 32GB factory cost of $600. For even more savings, iMac with Retina 5K display owners can trade-in the two factory base 4GB memory modules.

$200 off the True 4K LG 31MU97

For higher-end professional use, MPG uses and recommends the NEC PA322UHD (see review of the NEC PA322UHD).

The LG 31MU97 is now $200 off, making it $1175. See my review of the LG 31MU97 4K Display.

The late-2014 LG 31MU97-B 31-inch 4K display offers an attractive price, size, and form factor for a true 4K display (4096 X 2160). To use the 31MU97, a computer capable of driving a 4K display is needed. For Macs as of late 2014, that means the 2013 Mac Pro, 2014 iMac 5K or 2013/2014 MacBook Pro.

With a 4096 X 2160 resolution, I liked this display a lot. Image quality is gorgeous, particularly at a 2:1 eye-friendly display scaling of 2048 X 1080. The panel coating reminds of the NEC PA244UHD and has a very smooth but not shiny finish which makes the high resolution seem even more crisp. Your author greatly prefers it to the iMac 5K display, which is mirror-shiny.

How to save about $360 on a 20TB OWC Thunderbay 4

Here’s a way to build a 20TB OWC Thunderbay 4 with a configuration MPG uses every day (20TB solution highly recommended for photo and video pros):

UPDATE May 22nd: the B&H deal is over, and OWC pricing on Toshiba 5TB now has dropped aggressively.

  1. Order an OWC Thunderbay 4 with no drives (or RAID-5 edition with no drives).
  2. Order four 5TB Toshiba drives at B&H Photo for $140 each (the drives are out of stock, so delivery will be delayed, but can be ordered at this very low price). Consider a 5th drive as a spare. It’s a limited time offer, so don’t delay.

This is a terrific deal, total cost: $427 + $640 = $1067 vs the OWC price of $1430 (prices as this blog post was prepared).

BUT do note that OWC has a 90 day DOA guarantee on drives, 48 hour warranty service, 1 year data recovery service, and so buying the Thunderbay 4 from OWC with the drives included yields notable value over a cost-saving DIY approach as per above.

True 4K 31.5-inch display for $1174 (LG 31MU97-B 4096 X 2160 4K Display)

Here’s a deal that may appeal.

Normally for my professional clients I recommend the NEC PA322 UHD wide gamut display with color calibration (SpectraView II software + hardware). See the 5 page review of the NEC PA322 UHD. But the price is a bit steep for most users (about $3045).

MPG has also tested the LG 31MU97-B 4096 X 2160 4K Display and it is a very nice display too, supporting most of the AdobeRGB color gamut.The LG 31MU97 works on the 2013 Mac Pro and late 2013 MacBook Pro models onward. It offers a very enjoyable viewing experience.

B&H Photo has the LG 31MU97 for $1175 ($225 off, add to cart for the reduced price).

Tested: Lexar 128GB 1066X Compact Flash Digital Camera Storage Card

It’s not as fast as the Lexar 2000X Lexar Professional 64GB SDXC card, but this kind of speed is more than adequate for all digital cameras, even the Nikon D810 and the Leica S. This card will be put into field use soon for diglloyd photography.

MPG tested the Lexar Professional 1066X Compact Flash 128GB in the Lexar USB3 card reader on the 2013 Mac Pro, with results as shown.

As shown below, the Lexar Professional 1066X Compact Flash 128GB can write at 134 MB/sec and read (download to computer) at 154 MB/sec over the entire capacity.

UPDATE 11 May: I used the Lexar 128GB in the field in the Nikon D810, and it performed flawlessly. It will see a lot more use as my primary card in the field (for my cameras that use CompactFlash).

The Lexar Professional 128GB 1066X Compact Flash is a card for cameras of course, and it requires a separate card reader. So if you’re looking for a fast USB3 thumb drive, check out the OWC Thumb Drive.

The Best Way to use Apple’s Photos App

Update and warning: Leica M Monochrom Typ246 DNG files are currently incompatible with Apple’s ‘Photos’ App in Mac OS X Yosemite causing the library to crash and potentially lose all existing image files in the Apple Photos library. The bug is in Apple OS X Core Foundation libraries (the rot is literally in the 'core'). Yet more slipshod Apple software engineering—Apple Core Rot, but this time it is a data loss scenario, which is far more egregious than other types of bugs.

Update followup: it turns out that the library is not lost, just that it cannot be opened because it crashes every time. Apple will probably fix the bug at some point.

As a professional photographer, and noting the demise of Apple’s Aperture, it appears that the following approach is the best way to use Apple’s new Photos.app .

First, if you want to keep a copy of Photos around, right click on it and compress it to a zip file. Then remove it in Terminal (the Finder won’t allow it to be deleted, saying “required by OS X”):

sudo rm -rf /Applications/Photos.app

Best way for a professional to use Apple Photos app

Speaking to professionals, MPG strongly recommends eliminating as a workflow dependency any Apple software product except OS X. Apple has thumbed its nose at both video and photography professionals now, both with hardware and software. Migrate work to Adobe Photoshop CC or Adobe Photoshop Lightroom.

Professional users are now a tiny minority of Apple’s customer base, and thus are at extreme risk of being shrugged off and ignored (well, that’s long since happened). MPG has written on this starting three years ago, and subsequently many times in various ways.

Arne K writes

More serious anger from pro users:

http://preta3d.com/os-x-users-unite/ “OpenCL GPU drivers for OS X are broken and are unable to render but the simplest of scenes”

http://lists.blender.org/pipermail/bf-committers/2015-May/045367.html “going to abandon OS X as a serious 3D/graphics development platform”

MPG: tip of the iceberg. Professional users that relied on Apple for years feel betrayed. The above are just two specific examples, a tiny sliver of the issues.


Isolating/Blocking Hard Drive Vibration, Especially on a Hardwood Desk or Floor

MPG gets emails on fan noise periodically, so here’s summary of issues and mitigations.

Fan noise

Fan noise is often only a portion of the noise that one hears as “fan noise” in an external drive enclosure (unless the unit is using only SSDs, which need cooling, hence the fan). Full size hard drives make their own noise, particularly if they are 7200 rpm drives and there are four of them in an enclosure; the noise can “overlap” in harmonics in some cases, which can be annoying.

In general, decibal ratings for noise are fairly useless because the pitch as well as any oscillations in intensity or unpleasant harmonics can be far more annoying than a steady whir.

Fan noise can be completely avoided with single drive enclosures, such as the OWC Mercury Elite Pro (no fan).

For noise, get a 3 meter or longer Thunderbolt cable, and place the unit under the desk or in a closest or some distance away from right next to your work area. Put some sound-absorbing material around the unit too.


Placed on surfaces like concrete flooring, hard drive vibration is of little concern. But placed on a hardwood desktop or floor, those vibrations can resonate into the material in a very disturbing way (often a low humming vibration). Or not, depending on the material. While the enclosure itself can eliminate some frequencies, certain frequencies are not attenuated and make it through to the surface on which the enclosure rests.

Even the best drives have some vibration, and if with 4 or 8 drives in a RAID, it gets worse. If there is a vibration problem, try 1.25 sorbothane bumpers. They work well to detach any vibrating device from a hardwood floor or wooden desk or similar.

What also works very well are Auralex MoPAD Monitor Isolation Pads. MPG uses these pads under the OWC Thunderbay on hardwood floors, because the flooring picks up vibrations very efficiently.

As reader Don H points out (and MPG has used the same approach at times), the closed-cell foam in which OWC drives are shipped works great as a base also.

Detecting Corruption / Validating Data Integrity Over Time and Across Drives and Backup/Restore

IntegrityChecker verify command

An overlooked aspect of data management is data integrity: are the files intact tomorrow, a year from now, on the original drive and backup drive(s), or perhaps even on a DVD or BluRay. Or after having been transferred across a network.

Knowing that files/data is intact with no damage is a key part of any system restoration/update/backups/archiving. In some situations it could be mandatory (record keeping). The more valuable the data, the more important it is to consider the risks to loss, which include loss by file corruption as well file deletion (not to mention viruses and software bugs and user errors).

“Data” can mean image files (JPEG, TIF, PSD/PSB, etc) or video clips or projects, Lightroom catalogs, etc. Or it could mean spreadsheets, word processing files, accounting data, and so on. Knowing that these files are 100% intact leads to a comfort level in making system changes in storage approaches.

How can data be damaged? Disk errors, software bugs in applications or drivers or the system itself can happen. Moreover, the “damage” could be user-induced: saving over or replacing/deleting a file inadvertently. Simply having a “warning flag” could be useful in noting that “no expected changes” is violated.

For example, suppose that a new computer system is acquired and various drives need to be transferred over. Or that you have upgraded to a newer and larger hard drive. Or swapped SSDs. Or there is a need to restore from a backup. Or that you burned files to a DVD or BluRay—are they intact with no changes? Even RAID-5 with its parity data does not validate files when reading them, and a validate pass is over the entire volume with no selectivity for the desired file(s).

Enter IntegrityChecker, part of diglloydTools: at any time, files of any and all types can be checked against a previously computed “hash”, a cryptographic number unique to the file. If there is a mismatch, the file has been altered, somehow. This check can be made at any time: on the original, or on a 1000th-generation copy of that file. The only requirement is that the hash be computed once and remain in the same folder as the file for later reference.

How it works with IntegrityChecker.

IntegrityChecker computes a SHA1 cryptographic hash for each file in a folder, storing those hash numbers in a hidden “.ic” file within that folder. Thus, all files in the folder have a “hash value” against which its current state can be checked.

The process can be run on folder(s), or an entire volume.

  1. Run Update on the original files (computes and writes the hash values for every file in each folder into a hidden “.ic” file in that folder).
  2. Make the copy or backup or burn the DVD/BluRay or whatever (this naturally carries along the hidden “.ic” file in each folder).
  3. At any later time (tomorrow or a year later), run Verify on any backup or copy (this recomputes the hashes and compares to the values in the “.ic” file).

For example, some pro photographers burn DVD or BluRay discs containing folders on which IntegrityChecker has been run; these discs carry along the “.ic” file in each folder, and thus can be verified at any time. There are numerous such uses.


Both command line (Terminal) and GUI versions are provided. The GUI is basic, but the internals are what counts: one of the most efficient multi-threaded programs of any kind you’ll ever find. IntegrityChecker runs as fast as the drive and CPUs can go. Available commands include 'status', 'update', 'verify', 'update-all' and 'clean'.

See How to Safely Transfer Data or Verify Backups and also Example of Verifying Data Integrity.

Continues below.

Worth doing or happy go lucky?

For many computer users, the consequences are of little importance if a few things go bad: a song, a picture, a particular document; no big deal. But even such users would be upset losing years of photos—bugs in software (gray swan?) can have widespread impact; data integrity checking is a sanity check on assumptions.

But in a financial and obligatory professional duty sense, professionals need to consider the end-to-end processes they use. When data is one’s livelihood, attention to data integrity takes on new importance.

The greater the value of the data and the greater the time span over which the data has value, the more important it is to implement processes that minimize the chances of loss, because over years the storage format is likely to change with transitions and copying, etc. Also, knowing that a backup restored from a crash is valid takes some of the sting out of a crash.

How To Partition a Drive to Free Space Using Disk Utility

Here’s how to wipe out all volumes on a drive (SSD/flash drive or hard drive). This does not write over the data, but it destroys all file systems and partitions on a drive.

Essentially the drive becomes “unformatted” and like it was out of the box, though it generally does not wipe out set-aside special areas on the drive, e.g. writeable areas or writeable non-volatile flash used by firmware.

There might or might not be salutary effects with Apple-supported flash/SSD drives (eg TRIM total reset).

  1. Select the drive on the left (not the volume(s) listed under the drive.
  2. In the Partition tab, choose 1 Partition with Format: Free Space.
  3. Click Apply.

This results in 100% data loss on this drive, so don’t choose the wrong drive.

OWC Jupiter Ideal for Video Storage; NAS and/or SAN at 10 GBps, up to 512TB

I stopped by at the OWC booth at NAB to see the OWC Jupiter system.

With up to 512TB of capacity and functioning as a NAS or SAN and with 10 gigabit connectivity (additional 10 Gbps cards can be installed for more bandwidth), the unit is a heavy duty rack-mount solution for those looking for massive storage for a workgroup. Redundant power supplies of course.

LAS VEGAS, NV - April 15, 2015 – Other World Computing (OWC), a leading zero emissions Mac and PC technology company, announced today that it will feature at its NAB 2015 Booth #SL13905 in Las Vegas, April 13-16, a range of outstanding and flexible solutions aimed at revolutionizing creative professional workflows.

The innovative solutions showcased at OWC’s NAB booth include:

Jupiter Callisto and Kore Unified Storage

OWC Jupiter Callisto and Korerack-mounted storage solutions offer the most flexible, compatible, and scalable high-performance storage systems for creative professionals working with HD, 2K, and 4K workflows. Connect via 10Gb/E and mini-SAS interfaces to unleash speeds up to 10Gb/s via Callisto and up to 48Gb/s with Kore.

Jupiter Callisto, available now and starting at $4,988 for a 16TB configuration, is a unified storage appliance that functions as both a NAS and SAN at the same time. Mac and Windows compatible, it offers storage management with IP-based remote management software. Whether building from the ground up or integrating into an existing system, Jupiter’s 8-bay 2U racks and 16-bay 3U racks provide installation flexibility with scalable ZFS architecture for the creation of an ideal professional workstation environment.

The power of the Jupiter Kore, available now and starting at $3,288 for a 16TB configuration, lies in its mini-SAS interface architecture, with the ability to run dual 24Gb/s direct mini-SAS cables to achieve speeds up to 48Gb/s. Users can get up to 64TB of storage in an 8-bay rack and up to 128TB of direct-attached or expansion storage capacity in a 16-bay rack. Callisto users can add up to three Jupiter Kore expander rack solutions for a total of 512TB of centralized storage. Need even more power? No problem. Simply add an external SAS switch and watch limitations on speed and power vanish.
