comment ZFS SSD Trim and Software Raid 5
1) In fact the large disks (several TB) could take so long to sync in a traditional RAID that you risk a second disk failing (fatal!); 2) No, IMHO you should use traditional disks with lots of cache unless you have and application where performance is above reliability (like large video processing);

comment ZFS SSD Trim and Software Raid 5
IMHO it is a little early to implement SSD RAID - the I in RAID is meant for Inexpensive! :-) - seriously, the benchmarks I've seen are not that encouraging compared to more established alternatives (like battery powered disk controller with lots of cache).

comment Linux Software Raid runs checkarray on the First Sunday of the Month? Why?
Modern mirroring should be done only for inodes in use. IMHO, doing the mirroring at filesystem level instead of at controller level is more suited for the huge HD sizes currently available.

comment Show each file's read/write rate in Linux (CentOS)
@icando: I'm not aware of any tool to measure disk I/O by file. I'm curious, why you want to measure I/O by file instead of by process?
