Just looking for confirmation on my RAID config to see if it looks right. Given that the following drives are all 5900 or 7200 consumer drives, and not 15k SAS drives or SSD's, Do I have the correct configuration, or should I change something to make things faster?
Using the following:6x Seagate ST3000DM001 3TB drives in RAID 5 (5 + 1 Hotspare)4x Samsung HD204UI 2TB drives in RAID 102x WD WD20EARX 2TB drives in RAID 14x Supermicro 5-in-3 drive cagesIntel RES2SV240 24 port SAS expanderLSI 9260-8i RAID Controller
LSI Raid card is connected to SAS expander via 1 cable at the moment, I'm leaving the 2nd cable off as I might add an external array later if I need more storage.
the RAID 5 is used for >4GB Movies, >1GB TV Show episodes, and ISO images of OS's and apps only
the RAID 10 is used for Hyper-V VMs Only)
the RAID 1 is used for system backups from my laptop, desktop, HTPC, and netbook
I'm seeing the following performance:6x Seagate ST3000DM001 3TB RAID5 (1MB Stripe, No RA, Write Back, Directed IO, Disk Cache Disabled):
4x Samsung HD204UI 2TB RAID 10 array (1MB Stripe, No RA, Write Back, Directed IO, Disk Cache Disabled):
2x WD WD20EARX 2TB RAID 1 array (32 KB Stripe,No RA, Write Back, Directed IO, Disk Cache Disabled):
