OWC ThunderBay 8: Speed vs Transfer size, RAID-0 vs Fault Tolerant RAID-5

The OWC ThunderBay 8 is available in configurations up to 128TB (8 X 16TB).

See my in-depth review of the OWC ThunderBay 8—awesome unit!

Added is an evaluation of RAID-0 Stripe vs fault-tolerant RAID-5:

OWC ThunderBay 8: Speed vs Transfer size, RAID-0 vs RAID-5

RAID-5 offers outstanding performance for reads, and very good performance for writes. Since reads are generally far more common, the practical implication is that RAID-5 performance in the OWC Thunderbay 8 is outstanding for most all uses with the benefit of fault tolerance. The speed difference vs RAID-0 will be of nil consequene with most all applications. Besides, running an 8-drive RAID-0 stripe is unwise, due to the risk of losing the entire volume from a drive failure.

2019 Mac Pro and Kernel Panics with PCIe Cards

Yet more Apple Core Rot, it seems.

Tim Standing of SoftRAID has a must-read article for 2019 Mac Pro owners with regards to kernel panics and PCIe cards and how to work around the problem until Apple fixes it in macOS.

Investigating and Preventing Kernel Panics in the 2019 Mac Pro

... We determined that the kernel panic occurs when the 2019 Mac Pro sleeps. More importantly, we figured out that the problem only occurs when the OWC Accelsior 4M2 is installed in slots 4 or 5 and only if those slots are configured to use pool B of the PCIe lanes (see below). If OWC Accelsior 4M2 is in any other slot, or if it is configured to use pool A, no kernel panics occur.

The teams also found other cards, which, when installed, result in a kernel panic. One example is the Highpoint SSD7101A.

Getting Help From Our Chip Supplier

We then contacted our PCIe chip supplier in Taiwan to get help determining why macOS thought there was an error on the PCIe bus. Their engineers analyzed the signals on the PCIe bus and told us that macOS was mistakenly indicating that there is an error when, in fact, all the signals were correct.

Apple Starts Investigating

We have since reported this problem to Apple and are working with them to develop a solution. Like the problem we discovered recently — where a Mac hangs while transferring large files — I am confident that they will develop a quick and reliable fix for this problem.

How to Rename Files in the Finder

The macOS Finder has a quite limited but very useful means to rename files. I use this feature just about every day multiple times for various things.

  1. Select the items to be renamed
  2. Right click (or control click); choose Rename N Items...
  3. Using Replace Text to replace text with other text or Add Text or Format.
  4. Click Rename.

Job done. The negatives include no ability to use regex; the feature is very useful but also has no depth or elegance for more complex actions.

Long Term Usage Report: WeBoost Cell Signal Booster Greatly Expands my Camping Site Options and Saves the Day on Internet Access

Back in July of 2018, I began using the WeBoost Cell Phone Signal Booster in my Sprinter Van. See that post for why a personal hot spot and internet access is critical to my business operations.

UPDATE: the weBoost Drive Reach (470154) Vehicle Cell Phone Signal Booster is a substantial upgrade over the weBoost Drive 4G-X. Testing is in progress, but I am seeing more than double the upload speed with the 'Reach' vs the 'Drive 4G-X'—WOW! The 'Reach' is also better built with better antenna and easier to connect cables and heat fins for the main unit, so I expect excellent longevity.

Poor cell signal in your home or office? Check out weBoost Home Booster.

Original post...

weBoost Drive 4G-X 470510 Cell Phone Signal Booster

After 18 months of usage, I can now report exactly as to its value: worth every penny!

Background

I travel for photography in my Mercedes Sprinter photography adventure van often in remote areas where cell phone coverage ranges from excellent to barely there to not at all. My #1 issue when traveling is the availability of a good cell signal.

I frequently upload 100MB to 500MB (half a gigabyte) to my server at a time, for my photography publications and photo blog and cycling blog, with many high-res images. But it’s not just about lots of data—even email can take half an hour with a weak cell signal because it is very “chatty” back and forth with high latency so that even a 64K email can take 30 seconds when the signal is just usable.

I hugely prefer locations where I have peace and solitude free of the noises and campfire smoke and idling engines of other people (I never stay in campgrounds for that reason). But I also need a cell signal or I am forced to make as much as an hour round-trip to get one to check on business. So it’s a Big Deal if I can get a usable signal versus not.

View external SSDs excellent for travel.

Experience

See the tests I did back in 2018 in my original report on the WeBoost Cell Phone Signal Booster to get a sense of the improvement possible. The numbers don’t tell it all however.

Many desirable locations have signals that are so poor that a reliable phone call cannot be made and/or with the phone sometimes losing the signal entirely. I am writing this blog post in such a location, shown below.

Without the booster in this location, I get No Signal inside the van, and even climbing up another 100' on a nearby hill the signal is not usable and phone calls drop. This would rule out one of the best locations I have ever found for complete peace and privacy, a good thing when recovering from COVID-19—peace and quiet and rest to boost the immune system. The 100°F heat in the valley would be very stressful nor is noise acceptable.

So in this location, the WeBoost cell phone signal booster totally saves the day! While speed with this weak signal is only a few hundred KB/sec, that is perfectly usable even for large uploads—and even Netflix at low-res streams just fine. All that vs unusable.

Summing up, the value of the cell phone booster for me has proven out not to be so much as increasing data transfer speed (which it does well), but about turning unusable locations into usable ones.

Notes on roof height and external antenna

My Mercedes Sprinter is 9.5 feet high and the external antenna at top rear gets it up and out of the van, avoiding any blockage from the metal carapace of the van. While the extra height might help in some situations, I deem this of little significance in most cases. I expect that an SUV with a 6-foot-high roof should see be little difference, though there may be situations where large rocks and such matter such that the height is a variable.

The main thing is the external antenna. Driving sometimes in tight quarters, it is critical that the antenna be able to be pushed out of the way should I miscalculate. I am happy to report that this is exactly what happens; it just ends up on the rear of the van with no harm done.

OWC Doubles SSD Capacity for Accelsior 4M2 PCIe SSD, Thunderblade, Envoy Pro EX

This is awesome... like when hard drives made the leap from 8TB to 14TB in a few short years—that solved a lot of storage headaches for users with a lot of data.

For photographers like me (Lloyd) and/or videographers, the difference between 8TB and 16TB or 4TB and 2TB in practical terms is a HUGE leap in terms of convenience: a lot fewer cables and cards and power draw along with increased reliability on the Thunderbolt bus.

Here the leap is a doubling of SSD capacity so supersized that most users could store everything they have and will have until the next leap year or beyond!

The 16TB SSD capacity also matches up well to hard drive capacities of 14TB or 16TB (for backups, etc).

With three 8TB OWC Accelsior 4M2 PCIe SSDs in my (Lloyd’s) Mac Pro (24TB total), the slots were starting to look pretty full. The option at some future point to have 32TB internal SSD in a Mac Pro with only two slots used is highly attractive, as is the ability to travel with a 16TB OWC Thunderblade SSD holding everything (images) I’ve shot in the past decade—awesome!

4TB 'blade' makes it possible

The OWC 4TB Aura P12 M.2 NVMe SSD technology forms the basis for a doubling of capacity in a bunch of different SSD options:

Why Is My Mac Hanging When Copying Files After Upgrading to macOS Catalina 10.15.4?

Developer Tim Standing of SoftRAID explains a new problem in mac OS Catalina 10.15.4 in Why Is My Mac Hanging When Copying Files After Upgrading to macOS Catalina 10.15.4?.

A few days after the macOS 10.15 update was released, we began to hear of “Finder hangs” from DITs (Digital Imaging Technician) on movie sets. They were having their Macs stall when transferring hundreds of gigabytes of video from their 4K and 8K camera cards to their OWC ThunderBlades and ThunderBays. Anytime we hear about this type of problem, we immediately start looking for a cause.

A day later, we were able to reproduce the problem 100% of the time by copying 300 GB of large (10 GB) files from one SoftRAID RAID volume to another. Using a kernel debugger, we determined that the hang was not caused by an error in the SoftRAID driver. We then were able to reproduce the hang on an AppleRAID volume, using the AJA System Test Lite test application.

Once we proved the hang was not a problem with the SoftRAID driver, we alerted Apple engineers to the issue and collected further information to help them with their investigation. I can’t say when Apple will release the fix for this problem, but in the past, when they have been alerted to a hang or kernel panic, they had it resolved in the next update to macOS.

We Discovered a Temporary Work-Around for macOS 10.15.4

...

Once Apple releases an update to macOS 10.15, which fixes this issue, you can revert your Mac to the normal NVRAM settings and re-enable SIP.

MPG: see the blog post linked above for the work-around.

Apple’s focus on security lockdowns is creating serious problems at times. We can only hope that better testing is instituted at Apple going forward.

2019 MacBook Pro Seems to Have a High Failure Rate

James G writes:

I recently wrote to you about problems with my MacBook Pro 16” running OSX10.15.3 Crapalina having issues with restarts and shutdowns while sleeping.

I mentioned this to an acquaintance who is the manager of our local Apple Store and she said that they had not been seeing any problems like this with other MBP16 customers. She suggested I contact Apple support or bring it in to Genius Bar, which I did. I was impressed. They were fast and efficient.

They determined that there was indeed a hardware problem, probably the logic board, but the problem was esoteric enough that their local diagnostic tools weren’t sufficient. So I updated my Carbon Copy Cloner backup and took the machine back in the next morning to be spirited off to Apple’s central repair facility near Houston.

ll I can get from their progress emails is that it took them less than an hour to determine the problem and order “a part.” I suspect it’s a new logic board but since my MBP was a custom config with 4TB SSD and maxed RAM all soldered to the motherboard I bet the whole assembly has to come from China and what with the Covid situation I may have to wait awhile.

I’ll update you when my MBP is returned and I have a chance to test it.

... March 26...

I finally got my MacBook Pro 16” back from Apple repair. You may recall in a previous email I stated that it was crashing while sleeping. Bad logic board, which had to come from China (I assume) since the RAM and SSD are soldered on during manufacture. As mine was a 64GB RAM and 4TB SSD I don’t imagine they had a bin of those sitting around at Apple’s US repair facility.

The info they sent with the returned laptop says they replaced the logic board, the Touch ID board and the Lid Angle Sensor. The logic board swap presumably used a new SSD as there was a virgin system installed and none of my apps or data. A full restore using Carbon Copy Cloner got me up and running within 30 minutes.

So far so good, except now the right side of the keyboard backlight doesn’t work, though it worked OK before I sent it to them. Grrrrr….

It will be back to Apple once the COVID-19 dust settles. But if they have to wait another two weeks for a part from China I’m just going to buy a new one, get this one fixed and sell it. Apple won’t declare a hardware item DOA and give you a new one unless you buy it directly from them.

So far this is the fifth apple laptop I have owned and the last four have all needed a new logic or video board at some point. Understand, I usually drive my laptops until they drop, but this last one was bad from the get-go.

MPG: this is the 3rd and maybe the 4th bad 2019 MacBook Pro logic board replacement I have heard about—two from consulting clients and one from reader.

NEVER have I had so many reports directly from readers/clients. It seems that Apple has serious qualitiy control issues. Be sure to buy AppleCare with the laptop.

macOS: Apple 'TrueTone' and Display Profile Problems

Chris R writes:

If True-Tone is turned on, it screws with your display color calibration, over and above what is specified by the monitor profile. This screwing with colors depends upon ambient lighting. Ugh!!!!

I was trying to understand why images were seeming to have different colors (white balance) at different times of the day. Online info also suggests that turning True-Tone off might help with the losing of display profile connection upon waking from sleep.

On the MBP 16”, I have had to reset my display profiles randomly multiple times per day after waking from screen saver or sleep, which sucks.

Seems to me that True-Tone is a stealth disaster for photographers who rely on a calibrated display.

ave you encountered this problem? Simple to fix by turning it off, but you have to realize it is there messing with your display by default. I didn’t realize this until just now. What are your thoughts on this? Are you still having the loss of color profile issues with your system?

... Just a brief follow-up to let you know that turning off True-Tone fixed the loss of display profile connection that we driving me crazy. Hasn’t come back in two days since I turned this ‘feature’ off. Now profiles seem to remain selected and operational.

...since turning off True Tone, the loss of profile on wake from sleep has never recurred. So that definitely fixed the problem, which had been happening multiple times per day when I had True Tone on.

MPG: I warned about Apple True Tone when it was first introduced, in my review of the 2018 MacBook Pro.

Some computers like my 2019 iMac 5K do not have Apple True Tone technology, and so I don’t have to deal with the issue.

Apple.com: Use True Tone on your Mac

Yes, it is an absolute disaster for those of us doing professional work. Turn off TrueTone.

Popular Video Conferencing App 'Zoom' is Rife with Security Bugs and Maybe Infiltration by Chinese Communist Party

Chris R writes:

Saw this article today in the press and wonder if you knew, or could shed more light on it, Due to the lockdown in countries, Zoom as you are aware is becoming extremely popular with businesses for conference calling.

https://www.theguardian.com/technology/2020/apr/02/zoom-technology-security-coronavirus-video-conferencing

Keep up the excellent work with the Sigma FE 105mm f/1.4 DG HSM Art, could you show some more f1.4 images and bokeh.

MPG: my information has been that most Zoom engineers are Chinese nationals, and that Zoom routes traffic through Chinese mainland servers. As such, I would never have used it as the foregoing is a guarantee that the Chinese Communicate Part (CCP) has monitoring systems in place for intellectual property theft.

See TidBits: Every Zoom Security and Privacy Flaw So Far, and What You Can Do to Protect Yourself for an excellent summary of flaws with Zoom.

In my view, this guarantees spying by the CCP (Chinese Communist Party), if only because of the lack of end-to-end encryption, even forgetting that Chinese nationals can be imprisoned or worse if they do not follow the direction of their CCP handlers.

To be clear: my view is that The Guardian is NOT a source I generally trust for balanced reporting, with a pronounced polititical bias leading to no effort spared to avoid discussing both sides of an issue. So in what follows, I expect any counter-evidence to be omitted. Still, it's hard to get around all the security references in this particular article.

The Guardian: ‘Zoom is malware’: why experts worry about the video conferencing platform

In the last month, there was a 535% rise in daily traffic to the Zoom US download page, according to an analysis from the analytics firm SimilarWeb. Its app for iPhone has been the most downloaded app in the country for weeks, according to the mobile app market research firm Sensor Tower. Even politicians and other high-profile figures, including the British prime minister, Boris Johnson, and the former US federal reserve chair Alan Greenspan, use it for conferencing as they work from home.

But security researchers have called Zoom “a privacy disaster” and “fundamentally corrupt” as allegations of the company mishandling user data snowball.

And on Thursday, the company announced it would freeze all new feature development and shift all engineering resources on to security and safety issues that have been called to attention in recent weeks. Here’s what you need to know about the challenges with Zoom:

‘Zoom bombing’ on the rise

On 30 March, the FBI announced it was investigating increased cases of video hijacking, also known as “Zoom-bombing”, in which hackers infiltrate video meetings, often shouting racial slurs or threats. Zoom meetings can be accessed by a short number-based URL, which can easily be generated and guessed by hackers, a January report from the security firm Checkpoint found. Zoom has released guidelines in recent days about how to prevent unwanted guests from crashing video meetings and a spokesman told the Guardian it had also been working to educate its users on protections through blogposts and webinars.

No end-to-end encryption

Zoom has falsely advertised itself as using end-to-end encryption, a system that secures communication so that it can only be read by the users involved, a report from the Intercept found. Zoom confirmed in a blogpost on Wednesday that end-to-end encryption was not currently possible on the platform and apologized for the “confusion” it caused by “incorrectly” suggesting the opposite.

Security flaws

A number of security flaws affecting Zoom have been reported in the past and as recently as this week. In 2019, it was revealed Zoom had quietly installed a hidden web server on user devices that could allow the user to be added to a call without their permission. And a bug discovered this week would enable hackers to take over a Zoom user’s Mac, including tapping into the webcam and hacking the microphone.

The company said on Thursday it had issued a release to fix the Mac issue, but the number of security issues with Zoom in the past make it as bad as malicious software, said Arvind Narayanan, an associate computer science professor at Princeton University. “Let’s make this simple,” he said. “Zoom is malware.”

In-app surveillance measures Zoom has been criticized for its “attention tracking” feature, which allows a host to see if a user clicks away from a Zoom window for 30 seconds or more. This feature would allow employers to check if employees are really tuned into a work meeting or if students are really watching a classroom presentation remotely.

Selling user data

A report from Motherboard found Zoom sends data from users of its iOS app to Facebook for advertising purposes, even if the user does not have a Facebook account.

MPG: the claims made by the Guardian article make Zoom looks like it ought to avoided by anyone in their right mind. Assuming these claims are accurate, trust has been forever damaged—these are not honest mistakes and they go beyond incompetence to by-design. Therefore, here in 2020, Zoom deserves the corporate death penalty, to be banned outright as a national security threat.

Jeff K writes:

It's possible that you've seen these links on Zoom, they'll just confirm what you already know about the app:

https://tidbits.com/2020/04/03/every-zoom-security-and-privacy-flaw-so-far-and-what-you-can-do-to-protect-yourself/

The hidden web server issue was our last straw in 2019, but many corporates would not abandon the app, but that's changing now and they are dumping Zoom.

MPG: Bruce Schneier is an expert and I recommend his assessment as a go-to source.
