Speed's nice, price-per-terabyte is important, but do something about endurance and how it acts when it dies. I want my drive to tell me "x and Y is broken, only Z is available, read your data before I die" instead of simply VANISHING from my system on next power up like EVERY FRICKIN SSD does right now (even ones promising read only failure mode like Intel).
- moe 12y agoAny electronics device can die at any moment without a chance to tell you anything. That's why you have to make backups and run your disks in a RAID.
- rasz_pl 12y agoYes, any electronic device can die, thats normal. What is not normal is SSD drive going dark just because there was a SMALL corruption on one of critical flash cells (usually caused by firmware error, or power loss or wear). Its quite rare for magnetic drive to die because of few bad sectors, on the other hand it seems to be a standard failure mode on all SSDs on the market.
- NoMoreNicksLeft 12y agoMy operating system files churn as much as anyone, but I don't intend to use SSDs for files that will be written and rewritten. I'll use it for the stuff that I want to write once and keep for 30 years. I have terabytes of such, already.
- rasz_pl 12y agoSSD is not for you then, data retention is very poor (single digit years, or few months until read speed degrades in case of Samsung 840 :P). Whats more mere reading degrades flash, current SSDs keep a log of how many times sector has been read, and reallocate that sector when it triggers because read operations upset stored values.
