On: How to find per-process I/O statistics on Linux

SSD's are cheap.

[blasdel → gnaritas]

...and cheap SSDs are pathologically bad at random writes -- at least an order of magnitude worse than an mediocre hard drive on average, with regular latency spikes of several seconds!

[wmf → blasdel]

When measured in $/IOPS, even good SSDs are cheap. I think the real problem is the lack of caching software (but I would think that).

[jacquesm → gnaritas]

Would you care to quantify that ?

[gnaritas → jacquesm]

I picked up my Intel (the good controller, MLC version) for $400, best upgrade ever, that's fucking cheap.
