OWC Thunderbay can be Partitioned into Multiple RAID-5 Volumes

RAID-5 is fault-tolerant meaning it can survive the failure of one of the drives: swap it for the spare and keep working—no downtime (keep a cold spare on hand, so buy one with the device, e.g. a 5th drive for a 4-drive unit).

MPG regularly receives emails on whether RAID-5 or RAID-4 can be partitioned into multiple volumes (or how to set up a Thunderbay 4 unit): a Thunderbay 4 can be used as a single huge RAID-5 volume, or (recommended approach) partition it into three separate RAID-5 volumes.

For example, instead of one 15TB volume, make three 5TB volumes. Or not use RAID at all, and use the drives as single non-RAID drives if fault tolerance is not needed (use a disciplined backup strategy). The MPG recommendation when using RAID-5 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 making backup clones.

See the MPG review of the OWC Thunderbay 4. MPG has five of these units—favorite storage device ever.

Back to School Time: a Used Mac for The Kids?

OWC has a good article on saving money for parents: Back to School: Using a Vintage MacBook as an Inexpensive Student Computer.

Macs aren’t cheap and any parent with more than one child knows just how fast costs can add up, just for food and shoes and clothes! Let alone computers.

As for new models, B&H Photo has the Apple 13.3" MacBook Air (Early 2014) 1.7 GHz / 8GB / 512GB for $600 off at $1249.

Upgrade Your Mac Memory

DEAL: MacBook Pro

This is essentially a newer version of the model I have used for 20 months as a workhorse in the field (2013 MacBook Pro Retina). I still use it daily as a 2nd machine for some grunt work.

Very approachable price for a solid machine:

Apple 15.4" MacBook Pro Retina (Mid 2014) 2.5 GHz / 16GB / 512GB for ONLY $1749

There is also the 2.8 GHz / 16GB / 1TB model at $600 off.

Or you can go whole hog with the 2015 MacBook Pro Retina 2.8 GHz / 16GB / 1TB model, but the gains are mixed, as shown in my review of the 2015 MacBook Pro Retina.

A simple and extremely compact way to store extra stuff on a laptop: SD cards

Lexar Professional 64GB 2000X SDXC
with supplied card reader

Most Apple laptops have an SD slot. It’s not super fast, but it provides a handy slot for inserting up to a 512GB card, which even in its tiny case fits into a wallet—really small.

While no substitute on performance for a quality USB3 thumb drive or external USB3 SSD, the tiny size has its uses and does double duty in a camera.

B&H Photo has the Lexar 64GB SDXC card with card reader now for only $84.99. This rockin' fast card is now my favorite and the card in that card reader hits about 300MB/sec! Great for big downloads at the end of a long day and far faster than using a built-in SD slot on a MacBook Pro.

In the past I trended to using CompactFlash cards, but that standard has lagged in both speed and capacity and it is sometimes a hassle to have to use an external reader. See also:

Lexar Professional 2000X 64GB SDXC Camera Storage Card (Tested in 3 Card Readers)

Lexar Professional 1000X 256GB SDXC Camera Storage Card

Lexar Professional 1066X 128GB Compact Flash Camera Storage Card

Even though it’s not the fastest card, I also like the Lexar 1000X 256GB SDXC for a simple reason: I can make a backup of all critical data and stick it into my wallet and not even notice it being there. Very cool. Get a 2-pack of Lexar 1000X 256GB cards for $275 (as this was written).

I hugely prefer high-capacity cards (64GB or larger) because in the field there is no need to erase them, thus they are an additional backup over and above downloading the day’s shoot (and backing that up too). Aside from cost, I’d be buying 128GB or larger cards for that reason, but for now 64GB serves me amply for most of my trips (not filling up).

DEAL: OWC Thunderbay 4 RAID-5 Edition with Extra 4TB Drive

OWC has the the OWC Thunderbay 4 with free spare 4TB HDD in tray on special this weekend for $1149 (about $350 off).

It’s the RAID-5 edition with an extra (cold spare) drive. That’s five 4TB hard drives total. Use the cold spare as a backup in the meantime—no need to let it sit in drawer (hint: buy a 2nd empty Thunderbay).

RAID-5 is fault-tolerant meaning it can survive the failure of one of the drives: swap it for the spare and keep working.

You can run the unit as a single 12TB RAID-5 volume, or (my preferred approach) partition it into three separate 4TB RAID-5 volumes. Or not use RAID at all, and use the drives as single non-RAID drives.

See the MPG review of the OWC Thunderbay 4. MPG has five of these units—favorite storage device ever.

UPDATE: OWC also has the 5.0TB Toshiba drives with 3 year warranty for $163.99. Perfect for the Thunderbay, and OWC’s 90-day DOA replacement guarantee* beats anyone out there that I know of.

* If a new drive fails within 90 days OWC will replace it with a new one.

For those who have been living in a cave, AshleyMadison.com is an adultery website. Its database or 40 million or so customers was stolen by hackers and has been posted online.

See also security topics, particularly All your passwords at risk with OS X and iOS, and Apple Sits on the Problem.

The riskiness of using the Cloud or messaging or things like that for adultery (are people really that stupid, yup) should be obvious to any non-unconscious person. And there are undesirable side effects when (not if) security is cracked, like the death penalty for adultery in some countries, or fodder for a divorce lawyer. The foregoing is true of ALL cloud services: Apple, Google, etc. They will all be compromised: it is “when”, not “if”.

Charging iPhone, iPad, any USB-Chargeable Device: Lupine USB One

As an avid cyclist and hiker, I have a variety of Lupine bike lights and headlamps. These are high-grade units, the sort of thing that one uses for the Iditarod or caving and so on—top flight. For example, the Lupine Betty R II is brighter than most care headlights, and can be programmed to many light levels and so on. As a photographer, night shooting is another use.

Lupine now adds value to the proposition with the release of the Lupine USB One, which allows any of the wide range of Lupine batteries to be used to charge USB devices. It’s a diminutive adapter that attaches to any Lupine battery. Plug a USB cable into it and charge.

Why invest in a plain charger battery when you can have the world’s best quality bike light or headlamp, and use its battery to do double-duty?

In the USA, GretnaBikes.com is the source for Lupine USB One and Lupine batteries and Lupine bike lights and headlamps.

Apple ID Account Hassles Continue

This is what I would write to Apple:

Dear Apple,

I have a strong password.

I do NOT want my account with a strong password disabled at Apple whim—you see, this is a constant hassle because my account is attacked regularly. So Apple disables my account every two weeks or so. This is not working for me, eh?

And why does my account disable itself immediately after I authenticate successfully for a system update? More Core Rot I presume? But in the Cloud too.

Worse, the strong password is a big hassle to enter on an iPhone or iPad. Apple actively encourages poor-quality passwords due to the ill-considered keyboard design: the back/forth to enter special characters and upper vs lower case, as well as the tiny size that I literally cannot see in dim light. And those tiny buttons on the keyboard are just too small for my chunky fingers. Worse, the keyboard won’t enlarge in landscape orientation to fill the screen; it stays miniature. I don’t feel like playing this tedious game of trying to enter my password correctly with a poorly designed UI.

Yes, I want 2-factor auth for any sensitive operation, and I want Authy, not some text message or a nuisance, like the ill-considered unlock code that I cannot remember.

— Lloyd Chambers

Apple disables accounts regularly

Update: 6 hours later I got the same dialog and had to repeat the unlock process... now I realize that I had not signed in immediately after completing most of the process (including the Apple recovery key)—the process is multi-step and its completion is ambiguous (no M of N guide through it). Then I was forced to verify my credit card info, even though I had not attempted to buy anything (just launched iTunes)—I just wanted to access my own stuff (from CD) on my local hard drive.

Piling on, under some conditions iPhone won’t let me listen to my own music (from CDs) without cellular service enabled (just great when there is no service or I want to be in airport mode). The kitchen-sink crapware that is iTunes and the even worse Music app on the iPhone throw up so many hurdles and problems for my uses: listening to audiobooks. I could list all the problems, but I’m probably a niche user in my voluminous use of audiobooks so I’m cutting my losses on time spent here.

For Nearly Two Years, the OWC Envoy Pro EX Delivers the Portability and Backup Speed For Travel

For almost two years now, the OWC 480GB Envoy Pro EX has served me during my photography trips, providing 480GB (or 1TB or 240GB) in a pocket-size and bus-powered format in its handy cloth carrying case. On a recent trip, I reflected on just how admirably this diminutive little SSD has served me (less so the 2013 Apple MacBook Pro on which one of the two USB ports has gotten loose and sloppy and thus flaky).

Every day, I download the day’s shoot to my laptop, then clone the internal laptop volume to the Envoy Pro EX. Stored separately from the laptop (should the laptop in its bag be stolen), the mini drive is a solid insurance policy against loss of my work*, which can never be replaced, only re-done, yet never the same.

Of course, the OWC Envoy Pro EX can do much more than be used as a backup drive, but for travel and/or backup, its form factor is just terrific.

Testing Multiple Drives for Consistency for a RAID or Similar


Among its many features, diglloydTools DiskTester offers a run-area-test command that can be used for relatively fast characterization of drive performance across its capacity. The results can be graphed to get a good idea of the drive performance.

For example, suppose a high performance RAID is envisioned: one laggard can cut the performance, since the slowest drive determines the peak speed.

As shown below, 8 samples were tested, and one of those eight is a significant laggard; this slower drive is best set aside as a cold spare or backup drive.

While DiskTester can test any number of drives simultaneously (via command line), testing should take care not to saturate the bandwidth; for example four fast hard drives can demand almost all of the Thunderbolt v1 bandwidth, and other devices on the bus could suck up bandwidth, disturbing the results.

More Apple Core Rot: Finder Sluggish Since 10.10.4 Update

More Apple Core Rot. The trend continues, and is worsening.

Ever since the 10.10.4 update, the OS X Finder now has about 1/2 second delays before things happen: dragging files to copy or move, opening and closing windows, switching between windows, etc. It’s a daily hassle that causes errors trying to do things.

When will Apple start fixing the rot?! It has gone on about three years too long now.

Maybe once the iPhone market growth reverses to negative, which likely won’t be more than a year or two, what with XIAOMI aggressively taking worldwide market share outside the US. Then perhaps Apple will realize that urinating all over the goodwill of the OS X/Mac fanbase is a very bad strategy.

Perry R writes:

I follow all your comments about Core Rot closely and thus far it has scared me away from upgrading from OS 10.9.5 Mavericks. Yosemite and the Mac’s performance was noticeably slower all around (2013 6 core Mac Pro, 64 GB RAM, Helios / 2-Accelsior RAID 1 Boot volume). It seems like all the versions past that offer no significant “must have “ features, introduce more and more bugs, and suffer from various performance hits.

With each new major release I find myself wondering if the time has come to upgrade, and El Capitan will again pose the dilemma for me.

I wonder if you could provide a few comments about the overall value of leaving Mavericks, which seems to be working OK for me for a long time now. I suspect many other readers of yours would welcome an “overview” article of how to decide if upgrading is worthwhile.

MPG: for a machine 18 months or so and older: stick what with is proven and works. Latest OS X is a rat’s nest of new bugs coupled to loss off functionality. Every day the bugs of OS X Yosemite impede my work (the File Open and File Save dialogs in particular). OS X Mail has bugs in search and Smart Mailboxes. Little things like this add up to significant wasted time.

It is a fundamental rule of code, that the more code, the more bugs* (and the more security problems). Apple keeps adding more (largely useless) functionality while breaking older proven code (introducing new bugs in formerly solid code) in trade for mostly eye candy and gimmicks.

OS X El Capitan reportedly is designed (in part) to fix bugs . MPG won’t be touching it until final release to see if that dubious claim is in fact true.

* Apple releases OS X 10.10.5 and the very same day, a zero-day exploit in 10.10.5 is revealed. Such bugs will always be found, the question is wether the OS becomes increasingly hardened against attack, or whether layers are cruft are piled on, containing new vectors for attack.

MPG’s view is that adult judgment of appropriateness and value at Apple is badly degraded vs historical wisdom (Apple had been a shining beacon for years), in that more and more code is introduced of dubious and often negative value, while old stable behaviors are broken. A slimming down of the OS and a strict and rigorous focus on security and stability are long overdue. Whether OS X El Capitan makes strides in that direction is irrelevant unless it initiates a trend.

J.P U writes

I have the same issue in a Mac Pro Mid 2010 12 Cores. This user describes the problem perfectly:


I tried all kinds of workarounds, but the only solution that works is reinstall the system and reinstall all software from 0 with a huge waste of time.

MPG: this does not seem to be the same behavior, but could be related.

Sometimes an install-over works (install over existing system). But I’m first going to see if 10.10.5 fixes it (just updated).

Blank Gray Screens When Dual Displays are Attached, Color Profiling on Dual Display

With dual displays, reboot the Mac and one is presented with nothing but a gray desktop—no login dialog, nothing. Rick S writes:

I updated to 10.10.4 and now my multi-display set-up only allows me to see the login screen when I have just one display plugged in.

When I startup with both displays plugged in I just see a blank grey screen on both displays. Once the log in screen appears on one screen (can’t have two displays plugged in) I can plug in the other and all seems to work as before.

Both thunderbolt cables plugged into different buses. I have a PA322UHD and a PA301W. Any thoughts? Seems like a strange bug. Any thoughts. 10.10.3 was working well for me.

Also, on a separate monitor related note I can’t seem to get the color temperature of my two monitors to match. Calibrating both monitors with spectraviewII. Any thoughts?

This Apple Core Rot bug has actually been around since 10.10.3, maybe even 10.10.2 (I forget). It happens to me 100% of the time when rebooting. It’s rather obvious that Apple no longer bothers to test dual displays much, if at all—Photoshop can’t zoom properly, color profiles don’t work properly on dual displays, and many more issues abound.

Workaround: turn off the 2nd display using its power button for a moment; the login dialog now appears. Turn the 2nd display back on, login and all is well. It is not necessary to unplug the display.

As for color matching on two displays, I cannot get that to work either—yet both are truly calibrated* with NEC SpectraView II. As far as I can tell, Apple has also broken color profiles on the 2nd display and only the primary (main display) is correct.

Apple Quality, and Particularly Apple Service Overseas

An accomplished photographer friend of mine writes on his absymal experience with the Apple MacBook Pro.

Not only did it come at a bad time in the middle various travel, but it was also the culmination of about a month of bad luck and entropy. First, the machine started to have odd UI lag issues. Then WiFi started to drop and be impossible to restore.

Then when I put it to sleep by shutting the lid, it would intermittently turn itself into a space heater: after a few hours of sleep, the computer would be so hot you’d need a towel to pick it up, it wouldn’t boot because it was in thermal shutdown and of course the battery would be completely dead. Since the screen wasn’t on, it was basically converting all 6500mAH or however much juice was in there into heat. Aside from being a fire hazard, it completely destroyed my confidence in that machine – and left a very bad taste in the mouth given the cost of the thing.

I’ve had excellent quality from Apple products, and excellent service here in the USA. But overseas, the game changes on service and support.

MagSafe Connector Disconnects? Fix it with the NewerTech Snuglet

When I travel for photography, I charge the laptop using a power inverter or battery source in my vehicle (I almost never stay in a hotel/motel). The rocky dirt roads are bumpy, the car is loaded up with gear; there is no flat table for the laptop to sit upon and charge in peace.

A pristine MagSafe connector port is bad enough—the thing just does not stay attached very well. But a troublsome flaw in the MagSafe design is that over time, small magnetic particles start attaching themselves inside the connector port on the laptop. I’ve had to dig out the larger particles with a knife blade, but always the very fine small ones are hard to get out. These particles exacerbate the hassles of an already too-loose connector, and so the darned charger plug is constantly coming off, which stops the laptop from charging. (The BatteryBox avoids this issue since it clips on, but it is not for charging).

Along comes a product I’d never have guessed existed: the NewerTech Snuglet. It’s a tiny little metal jacket that goes into the charging port. Two are included, and a tool is provided for removal (but I have no intention of removing it).

The NewerTech Snuglet just works. I am very pleased to have this problem-solver product; it kept my laptop power attached and charging on a recent trip. Fantastic!

Photoshop CC 2014 Now Gets the CC 2015 Bugs

I recently reported that a slew of new bugs had appeared in Adobe Photoshop CC 2015.

Now with the very recent update to Photoshop CC 2014, Adobe has apparently decided to backport the CC 2015 bugs into CC 2014, at least some of them.

Beware: the bugs involve the GPU, a notoriously unstable area. CC 2014 and CC 2015 have been crashing on me at 5X the rate of the previous versions.

Adobe appears to be steadily replacing proven and optimized non-GPU code with faster but unstable GPU code, while also apparently replacing optimized non-GPU code with turtle-slow code (maybe an internal overhaul of sorts).

So you now can choose fast unstable operation with the GPU code (regular crashes and malfunctions and/or broken functionality), or more reliable but turtle slow operation if the GPU is disabled (I have disabled the GPU for years due to instability).
