We have been using the Intel S3710 (or
minor model variations thereof). They have been great (consistent
performance, power off safe and good expected lifetime). Also 2 of
them in RAID1 easily outperform a reasonably large number of 10K
spinners in RAID10.
Now you *can* still buy the S37xx series, but eventually I guess we'll have to look at something more modern like the S45xx series. But I'm not so keen on them (they use TLC NAND which may give less consistent performance, plus they appear to have slightly lower expected lifetime). I think there was a thread a year or more ago on this list specifically about this very issue that might be worth searching for. The TLC NAND seems like a big deal - most modern SSD are built using it...they solve the high latency problem with SLC caches. So you get brilliant performance until the cache is full, then it drops off a cliff. Bigger/more expensive drives have bigger caches, so it is well worth finding in depth reviews of the exact models you might wish to evaluate! regards Mark On 10/04/18 14:36, Craig James wrote:
