SanDisk Portable SSDs Are Failing So Frequently, We Can No Longer Recommend Them

There was a time period where it almost made sense to use 2.5" SATA SSDs in hot-swap bays as if they were floppy disks. Unfortunately, the form factor proved unnecessarily bulky for the PC form factors that are popular today, and SATA was a dead-end for performance. But a typical consumer SATA SSD is durable enough for portable usage and more reliable than anything involving USB.
Most of us wait for someone who does do so to spread the news. Which is what is now happening.
Certainly not by thinking the marketing department is giving you the full story. I don't have a problem with news like this being reported. What I have a problem with is acting like it's a surprise, or acting like a user who loses 3TB of data because of the failure of a single portable drive is a blameless victim (especially when the failed drive in question was a warranty replacement for a previous drive failure).
How do you determine which ones are good, at the point of sale?
You don't. That information is not provided at the point of sale. You either research the products elsewhere before making a buying decision, or you make a purchase knowing it's somewhat of a gamble. (Occasionally Amazon/Newegg reviews may tip you off to important issues with a product, but that's an extremely poor signal-to-noise source of information.) Many people are quite happy to rationalize away the anxiety of that gamble by reassuring themselves with brand loyalty, which is how we get into situations like what prompted this article.
All marketing distorts the truth and omits unflattering information. Some marketing simply lies outright. If the information is coming from marketing materials or salespeople, you cannot consider it trustworthy on its face.
I'm sure others have their own personal anecdotes. Here's mine: I've run a number of Linux installs directly off Samsung external ssd's. Heck, I've used multiple Samsung miniature USB flash drives (so, not their fastest USB flash drives) as permanent installs (mainly for chromebooks with limited internal, non-replaceable drives) - they just extrude a tiny amount, so one can just leave them in, and treat them as permanent storage.
It just ... works. For ... years.
SanDisk sticks and ssds (especially their mini USB sticks) on the other hand, always seem to run too hot. Try a different manufacturer.
For the smaller USB-native flash drives, I have not noticed any particular pattern to their unreliability, but I trust them even less because that product segment is a dumping grounds for low-grade flash memory.
For NVMe-based portable SSDs in particular, I am wary in part because of the long-running thread on the AnandTech forums documenting how all three suppliers of NVMe to USB bridge chips (JMicron, Realtek, ASMedia) have had extensive problems with both reliability and compatibility. Companies like Samsung and SanDisk can certainly be expected to do more QA on their products incorporating those chips than smaller brands, but that's not a guarantee that they'll avoid the problems from their upstream supplier.
And "Backups aren't backups unless they're tested."
Of course I back them up to a 8tb portable hdd weekly using borg. You should do that no matter what brand of ssd you use!
It's the size of a pack of cards and has one USB 3 plug for power. Unfortunately the larger ones are quite a bit bulkier.
With borg I'm doing incremental backups and while slow, borg seems fairly slow anyway so I haven't noticed.
I wonder if it will get much slower once more of the disk has been written to.
Oh boy. Bit excited to find out more about this.
So no, dont _trust_ that drive too much :)
