Drive has a crazy problem
Reviewed in the United States on December 20, 2019
After extensive testing on Linux, the advertised speed is not an exaggeration. So that's good. It's also small and cheap, and that's nice.
However... It kept disconnecting on me. It seemed at first to just have a flaky usb connection or cable, but then I noticed that it would just do it *any* time I touched it. Even when perfectly stationary on a table, gently dragging my finger across the top of it would cause it to disconnect, and consistently so.
In other words, the external metal casing is electrically connected to the innards, and any external static (the kind of which is around all of us constantly) will cause it to screw up internally. Perhaps if I coated the entire exterior in some kind of plastic or rubber cement, that might fix it. Or perhaps I can crack it open and try to shim some paper insulator somewhere, if I can figure out where the connection is happening.
--edit-- It's worse than I thought. Drive can only maintain full speed for about 30 seconds before overheating. Avoid.
--another edit-- To further describe this drive's behavior, it will sustain high read speeds. But write speeds, while initially very fast, soon drop to around 10MBs. The drive's controller also does not correctly report its ability to receive TRIM commands, which Windows will simply ignore and issue the TRIM periodically anyway, while Linux won't. The drive can receive the TRIM command, but doesn't truthfully report that ability to the OS. So you have to force Linux to pretend that the drive has that ability (I have to use a 'sudo su' and an 'echo "unmap" >/sys/block/sdd/device/scsi_disk/*/provisioning_mode' on my Linux Mint). You can then issue a manual fstrim command. Which it needs on Linux since its performance degrades even more over time without it.
