Hi,
This is my current setup:
Supermicro X7DWN+ - Dual Xeon 5130 - 64GB Ram - 8x 4TB Seagate ST4000DM000 5900 rpm - 2x 4TB HGST HDN724040ALE640 7200 rpm - 1x 256GB Crucial_CT256MX100SSD1 - 6x 3TB HGST 7200 rpm -TDK LoR TF30 USB 3.0 PMAP (boot) - 2x Dell H310 SAS/SATA Controller in H16 IT Mode - 1x HP360T Gb NIC - Supermicro SC825 2U Chassis 920Watt Platinum PSU.
When I put 6 3TB 7200 rpm disks into stripe as a test I get 550 MB/s
When I put the 8x 4TB ST4000DM000 and 2x 4TB HDN724040ALE640 in 2 Vdevs of 5 disks, each vdev in RaidZ1 I get a measly 230 MB/s.
I also put all of them in RaidZ2 but it was even worse. Like 180 MB/s
They are all aligned properly but I can't seem to figure out why they are so slow.
Sure they are 5900 rpm drives, but if you put a bunch of them together they must be faster then this...
When I do my testing each drive has a R/W of about 20 MB/s.
Anyone any suggestions of what to try to get better performance?
Cheers,
K.
