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.

    I suggest to destroy the array and test drive performance one by one. LSI hardware raid controllers tend to hide SSD drive problems. I had similiar issue with almost dead SSD drive that hanged on any write-operation, but was reported by raid-controller as healthy, though write speed was dropping to kilobytes/sec. – anx Feb 20 '16 at 15:33
  • test one by one, speed like raid 1, but i test on other machine (microserver 6016tt , speed good, read =450mb / write=240mb/s, read 4k=28mb/ write 4k=19mb ) i think problemt is raid controllers p410i – pvd276 Feb 21 '16 at 5:13
  • The problem may be related with some other part of hardware in your server: cables, backplane, etc. I recommend to test drives one by one on the same DL360G6 and compare speeds. – anx Feb 21 '16 at 12:00
  • i test with all server hp use P410i, i test on DL380 G6, same problemt, i test on DL180 G6 witd P410i card in pci-e 8x, it better (read =440mb / write=160mb/s, read 4k=27mb/ write 4k=10mb ) – pvd276 Feb 22 '16 at 4:36
