Hi All,
I've got myself a FreeNAS system, but this post is not relating to that system. It runs well.
I've got a question relating a standard RAID setup using a Perc 5i RAID Controller.
Specs:
Intel i7 2700k
16GB 1600Mhz RAM
OS Drive - Crucial MX500 500GB SSD
RAID Physical Drives - 4 x WD Black (2010) drives with about 2-3yrs of usage previously in a RAID5
RAID Controller - Dell Perc 5i RAID Controller w/ 128MB RAM Cache (battery is dead)
Configuration is in a screenshot attached but basically:
RAID 0 - 4 x 1TB WD Black (2010) drives
Stripe Size - 16kb
Disk Caching Disabled
No Read Ahead
Write Through
I'm getting VERRRY bad write performance on it! This card should be able to handle 300MB/sec. The drives are probably in the 90MB/sec area so 4 in a RAID0 should be able to accomplish 300 or even 200.
I'm getting Minimum 1MB/sec.... Max 7MB/sec with an average of 5.5MB/sec. Please see RAID0-2 screenshot.
What can I do to increase the performance of this RAID0 setup! I want to use it for gaming, have a couple hundred GB of games on a single HDD and want it on this RAID. Copying the files over takes FOR-EVER due to this lack of performance. Any thoughts??
