Best PCIe controller for fast (500MB/s+) SSD ?
Posted 08 July 2011 - 09:26 AM
I have 4x Vertex 3 MaxIOP drives here that I purchased to build a Raid 0 array. I bought a Highpoint HBA 2720 (6gb/s SATA3 / pcie x8) and thought this would be a done deal. Problem is, I can't get more than 350MB/s out of a single drive plugged into this controller. We should be seeing 550MB/s.
So I'm shopping for a new one. I've asked OCZ / LSI / Highpoint / etc which controller will actually deliver full SATA3 throughput on a single port. And basically, none of them will disclose this information. "It's sata3 compatible" they say. Right - and I have a truckload of "1000Mbit/s" network cards here to sell you... they'll only transfer at 600Mbit/s, but hey, who's counting!
I'm doing the Raid in software, so I don't actually need a Raid card, just a pcie->sata3 card. I've heard that the P67 chipset is great, but new mobos are not an option. Can anyone help me out?

or buy some SLC drives and do not worry about anything. At least my 2 Foremay SLC (64 gb only) never degrade in performance.....no Cache on the drives, they are that good.
Here you can see what the drives perform on a ....... Adaptec 31205, not the greatest Raid Card ever. After 3 years of use, Trim not possible. Just ran Atto this week.
True LSI has great Sata-3 controllers, mine did get too hot actually....so i returned it.

forgot to add: here you can see the cristalbench of both the Adaptech and LSI back in 04/30/2010.
So as you can see not much difference from what i just added half an hour ago.
Why? Well i add to search for the LSI results. (You can hardly believe what a 6gb Card Sata-3 can do with Sata-2 drives.
do not know if both files will be attached, anyway i will add the missing file from 04/30/2010
