Anyone have experience with IDE, SATA, or SAS-connected flash devices like
the Samsung MCBQE32G5MPP-0VA? I mean, it seems lovely - 32GB, at a transfer
rate of 100MB/s, and doesn't degrade much in performance when writing small
random blocks. But what's it actually like, and is it reliable?
None of these manufacturers rates these drives for massive amounts of writes.
They're sold as suitable for laptop/desktop use, which normally is not a
heavy wear and tear operation like a DB. Once they claim suitability for
this purpose, be sure that I and a lot of others will dive into it to see how
well it really works. Until then, it will just be an expensive brick-making
experiment, I'm sure.
It claims a MTBF of 2,000,000 hours, but no further reliability
information seems forthcoming. I thought the idea that flash couldn't cope
with many writes was no longer true these days?
