I'm looking for, but can't seem to find a good PCI-E raid 5 card. One with a real Raid engine, not just an and/or engine, and on-line capacity increase functionality. Anybody know of one?.



Thanks,
Kyle
 
The raid 6 performance of the areca is pretty good from what i've read. Almost be worth it if i had the money.
 
About 78% of the raid 5 performance. Both over 150 MB/s, I might add. Does pretty well in other tests.

In summary, you get what you pay for, but dang it costs a lot.

 
I looked at the graph on that raid card roundup, but why is it that forum members are reporting actual file transfer speeds as low as 12MB/s. In the results there, all of them top 60MB/s write speeds. In the graph, the 3ware has over 100MB/s write speeds, but someone was reporting getting only 12MB/s.
 
Are you looking for SATA or SCSI? (or some other interconnect?) What's your price range? What link width is the slot you have for it?
 
XFX says they will release the PCIe version next month. I just bought the pci version hooked up to 5x250 Sata 3Gb drives. Still in the process of moving my data over. i will let everyone know how well it works. (my plan is to put this in my server and get the pcie version when I build my new pc in a few months.)

Still putting things together... had to dodge bad thunderstorms. Using hdtach, I got between 85-90MB/s constant, 106MB/s burst, with 7% CPU usage (although the rocketraid404 was still attached. This could have colored the Cpu usage a little). Once I get everything moved from my Rocketraid404 (450GB), I will see if I can get better benchmarks posted. So far the only issue i have had was I had to jumper the drives down to sata150. Very smooth install so far.
