It seems RAIDed SSDs would be the best. What issues have you heard of, with that configuration?
for RAID1 the SSD disks cant use Trim so they degrade faster, my SSD experience is limited still. I read that also Raid5/0 is nice with SSD but I would like to find some real usage feedbacks first before i set it up. From what I read that unless the SSD disk die completely due hw failure, the other fail scenario is they switch to readonly mode. Sometimes its also some temporary situation due firmware problems.
Now in case such event happens, I know how the controller would work with SAS/SATA disks, but unsure about the SSD especialy with the read only mode and raid5.
The RAID5 with SSD is safer or same/worse compared to regular disks?
I was thinking that instead going to pure SAS 15K in RAID10, I can try use hybrid setup such as SATA+SSD or SAS+SSD that can bring increased performance. So if somebody has already good RAID1 or RAID5 setups working with SSD, I would like to hear.
