Hi I currently have 3 crucial c300 256gb all running the latest firmware 0007. I am using them in raid 0 using a highpoint rocket raid 640. The card is a 4 x pci device and its in a 16 x slot with full bandwith. My issue is with 3 of these ssd's im only getting 580mb/s?? they state 355mb each and im getting 580mb for all 3?
I used to run 1 off my mobo and got 300mb so i exspectin perhaps 800 - 900mb/s
What can the issue be?
my motherboard is an msi bigbang xpower if it helps and the raid card is 6gb/s
The Highpoint Rocket Raid 640 does fairly well with 2 solid state drives in a RAID array. It does not perform well when there are 3 or 4 ssd's in a RAID array. The 3rd and 4th ssd's seriously hamper the card's performance. It's well documented in technical reviews.
The Controller on the 640 is not that good. An excellent high end, high tech, RAID card that kicks butt will cost a lot more than an ssd. I always tell individuals the really good cards start at about $1,500.00. The inexpensive card Dereck47 mentioned is okay but I would not recommend it.
