Have you ever actually worn out an SSD using personal workloads (ie, not on a server)? I haven't yet and I own machines/SSDs from 12 years ago - benchmarks are still roughly equivalent to what I had to start.
- Fnoord 6y agoYes, I have. My old ThinkPad R61 I added an OCZ SSD to. Not sure how much RAM it came with, but it was swapping a lot, I guess. Back then, SSDs had less of a lifespan than nowadays (even consumer-grade ones). I had the same on Windows + a SSD. Docker with some Sqlite applictions apparently did crazy writes. SSD went from 100% to 80% in like half a year time or so, when I noticed it. That SSD is still alive, but I had to adapt.
- mlindner 6y agoThose early SSDs if I remember right had very low cycle limits, the limits now are over 10x better than they were then.
- to11mtm 6y agoDepends which age/tech. Every additional 'Level' in the flash decreases the overall life cycle. Mind you, oftentimes drive controllers are fancier, often doing things like treating one of the sections as a less dense flash type to improve write cycles, and keep/move longer held data into the regions treated as QLC. But, that means that some heavy write patters will indeed wind up worse on a modern drive than the better MLC/TLC models.
- rasz 6y agoIts the other way around. Early SSDs had huge P/E numbers in tens of thousands (SLC). Now we are down in the low hundreds.
- freehunter 6y agoTo re-iterate how much more reliable SSDs are now that they used to be, until about a month ago I worked for a vendor of hardware/software that is designed to read/write to disks hundreds of thousands of times per second (log collection and searching). When I first started working there ~5 years ago, they were testing out SSDs in the appliances and the team ultimately decided against it because they estimated the SSDs would burn out in under a year. By the time I left they were shipping appliances with SSDs that were predicted to have lifespans longer than the longest hardware support you could buy from the vendor (longest hardware support contract - seven years). Hundreds of thousands of writes per second, every second, for 7+ years, uninterrupted.
- rasz 6y agoThey are most likely shipping bigger SSDs :-) Bigger the disk bigger the TBW despite P/E going to shits with every node shrink/bits per cell jump.
