Hello, Due to increasing load of random read IOPS I am considering using 8 SSDs and md in my next server, instead of 8 SATA HDDs with battery-backed hardware RAID. I am thinking of using Crucial m500s. Are there any gotchas to be aware of? I haven't much experience with SSDs. If these were normal HDDs then (aside from small partitions for /boot) I'd just RAID-10 for the main bulk of the storage. Is there any reason not to do that with SSDs currently? I think I read somewhere that offline TRIM is only supported by md for RAID-1, is that correct? If so, should I be finding a way to use four pairs of RAID-1s, or does it not matter? Any insights appreciated.
