For my company needs, we need a RAID 0 which can support high bandwith transfer for 4K video.
I bought the following items to test if it was possible to do it without big costs:
- Supermicro X9SRH-7TF
- Intel E5-2620v2
- 16 GB RAM 1600MHZ
- Western Digital Caviar Black 500GO 3.5" with Windows 8.1 x64 up-to-date as operating system
- RAID Controller LSI 9271-8i
- 4X Samsung 840 PRO 256GB
Everything has been updated:
- Windows 8.1 x64
- RAID Controller LSI 9271-8i (drivers + firmware)
- SSDs (firmware trough Samsung SSD Magician)
My problem is that I'm not a RAID expert at all and I don't know which parameters are the best...
I read that Samsung 840 PRO were not the best SSDs for RAID on LSI controllers due to problems with these SSDs but it was corrected with lasts firmwares right?
Currently, I use the following configuration:
RAID 0 Virtual Volume including my 4 SSDs with the following settings:
64 KB Stripe (also for NTFS properties when formatting my partition)
No Initalization (what is it by the way?)
No Read Ahead
Disk Cache is unavailable when configuring Virtual volume
I have the following results in Crystal Mark: 1630 MB/s READ / 1500 MB/S WRITE
And these results with our homemade application to test video bandwith on a disk: 1350 MB/S READ / 1180 MB/S WRITE
Unfortunately 1180 MB/s is a little bit short and I wonder if there is a way to have better performances...
- Are there better settings for RAID 0 with SSDs ?
- Will it be better with 5 or 6 SSDs or is it useless ?
Don't hesitate to ask me questions or further explanation if you need this to help me. As said before, I'm not an expert at all with RAID controllers especially with SSDs..
