Windows 7: Raid card suggestion

Raid card suggestion

hey guys I recently bought two ssds with these specs

Sequential Access - Read up to 230MB/s Sequential Access - Write up to 150MB/s
and put them into raid 0 with my on board raid. My average read time with these in raid 0 is only 123mbs, I don't know but i was expecting faster with them striped together. So i came to the conclusion that it is probably my onboard raid controller.

So i was wondering can anybody suggest some raid controllers, preferably in the 75 dollars or less range.

Thanks!

Well, it seems like you have some other issue going on here. 1 drive alone should be scoring in the 200+ range...so it seems like you either have SATA 1.5Gbps controllers or something isn't configured correctly. I would expect with a RAID 0 configuration, you would be around 420-470MB/s.

What motherboard do you have?

Even SATA 1.5 is more than enough bus width for those in mirror raid.

Let us know what your complete system setup is and what you are using to test the throughput.

Thanks for the fast reply! I have an Asus m3n-ht deluxe mobo Newegg.com - ASUS M3N-HT Deluxe/HDMI AM2+/AM2 NVIDIA nForce 780a SLI HDMI ATX AMD Motherboard

AMD athlon 64x2 dual core processor 5000+ 2.61ghz ( will soon be upgrading to quad core )

2 gigs ddr2 800 ( will soon be getting faster ram as well )

and here is a link to the ssds im using Newegg.com - A-DATA 500 Series AS592S-32GM-C 2.5" 32GB SATA II MLC Internal Solid State Drive (SSD)

I was expecting speeds around that fast as well, i'm gonna undo the raid array and do firmware updates on my ssds maybe that will help as well ?


Im usind hdtune pro for benchmark tests.

No, SATA 1.5Gbps is 1.5 gigabits per second. When converted down to bytes...that's roughly 150MB-160MB/s. So, a single SSD drive could saturate a Sata 1.5Gbps controller.

Also, the poster is not doing a RAID 1 "Mirror"...they are doing a RAID 0 "stripe".

Oops, you are correct on both accounts. Sorry about that and thanks for clarifying. I don't know what numbers I was thinking of when posting that.

yeah the onboard must have sucked cause i just did bench mark test on one ssd not in raid zero and my average read was 195mbs.

So any raid card suggestions?

or just suggestions in general.
