WOL: current SSD's are rated for around 1000-2000 writes. So a 1Tb disk can sustain 1000-2000TB of total writes. And writes to filesystem blocks would get re-written more often than data blocks. How well it would work would depend on how often the data is deleted and re-written.
When did that guy do that study of SSDs? Basically hammered them to death 24/7? I think it took about three years of continuous write/erase cycles to destroy them.
Given that most drives are obsolete long before they've had three years of writes ... the conclusion was that - for the same write load - "modern" (as they were several years ago) SSDs would probably outlast mechanical drives for the same workload.
(Cheap SD cards, on the other hand ...) Cheers, Wol -- dm-devel mailing list dm-devel@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/dm-devel
