I replaced a drive in coins; expect degraded performance.

| | Comments (0)
Coins is one of the servers that is new enough that it has the AHCI sata controllers, so there's no reboot required, but it's old enough that I was still buying 1tb drives (four of them) and short-stroking them.  This should dramatically improve sequential performance, such as an unloaded raid rebuild, but I do not think it will have as dramatic an effect on random access.  Really, I should benchmark under controlled conditions.
