I've experienced a few seriously strange issues with modern SSDs, even some of the better ones.
I had a 512GB Samsung drive that became very slow randomly at doing IO operations, the whole machine would die for 10-30 seconds at a time once or twice a day while any process that tried to use the disk became blocked on IO. Then it'd come right back like everything was perfectly fine.
Issues like this definitely worry me, we're basically completely blind as to what those controllers and flash chips are actually doing. Not that it wasn't a similar situation with HDD controllers before, but at least it didn't seem as unpredictable.
- Kye 8y agoIf the Bitlocker hardware encryption fiasco is any clue, the people who make SSDs don't know what's going on inside either.
- LeftTurnSignal 8y agoI've recently noticed similar issues with my older Crucial SSD in my 2012 mbp. In the past 3 months, there's been maybe 5 times where I started my laptop and it took 5+ minutes to finish booting. Normally, it's 15 seconds. Once I'm logged in, doing anything takes forever, but it does eventually load. A power off, and back on got it "working" again but who knows for how long. I've had this drive for 4-5 years now, so I'm impressed it's lasted this long.

- spatular 8y agoIf on Linux, try running fstrim from time to time. More free space makes life of SSD's garbage collector / defragmenter much easier. I've anecdotally noticed that running fstrim reduces freezeups under heavy load from 1-2s to almost nothing on my Toshiba drive.
