Uh, I've never had one fail gradually...

Yes, but they have a maximum write cycle, you can blow through the average consumer drive in a month and a half of concerted writing.
- eastdakota 13y agoThat hasn't been our experience. While we've optimized our file system to minimize wear, we do an extremely high volume of reads and writes on our SSDs. We have many SSDs (previous generations) that have been running full steam for 3 years in production. We've been pleasantly surprised with the number of write cycles they can endure without failure.
- peterwwillis 13y agoHow do you measure writes in this case? Do you use SSD write caching? Is your filesystem caching the writes? Would love to see some stats/graphs to show real-world metrics of disk resilience.
- eastdakota 13y agoWe'll do a post at some point on file system benchmarks and what we do to get the most performance and life out of our SSDs.
- bifrost 13y agoCare to share the brand/variety? So far I've killed Intel, Kingston, Micron, OCZ and a couple offbrands. Wasn't terribly surprised by the offbrands, a little miffed at the Intel though...
