I just bought a HP DL360G6 server with a P410i RAID card with 256mb cache. I am using Windows server 2012
I use Intel 520 series 240GB SSDs in raid 1+0, but the speed is very slow.
I checked the speed with crystal disk mark:
read =450mb / write=70mb/s
read 4k=29mb/ write 4k=0.7mb
I updated the firmware to 6.64 which is the newest version
I installed the smart array driver in Windows
I compared it to a 72GB SAS disk which has no problem:
read 120mb/ write=120mb
read 4k=1.2mb / write 4k=1.2mb
When creating a RAID5 with 4 Intel SSDs I get better speeds:
read 890mb /write 460mb
read 4k = 32mb/ write 4k=29mb
I want to use RAID1 for my disk, but can't fix this problem, the write speeds are very slow.
