Seems pretty inexcusable to release SSDs that get corrupted on power off.
These drives are defective, and they should refund customers for the SSD prices, plus some hefty compensation for the potential data loss they could have or have caused.
If you make a storage system and ack a write/sync, it had better be durably written.
- baruch 11y agoMost non-enterprise SSDs do not have an internal supercap or other power protection mechanism and they are not intended for a server use-case and shouldn't be used in such capacity. An HDD will not hold data that is written to its write cache either so the SSDs are well within the spec.
- arielweisberg 11y agoThat is not at all what the blog post is claiming nor is it the reality. It's also not what the commenter you're responding to is complaining about. The complaint is not about losing data in a volatile cache the complaint is that drives will lose data even after the drive has claimed to have flushed it's write cache after being given a write barrier.
