Pros: Inexpensive, easy to set up, fast and REALLY reliable

Cons: Needs a separate cable, a few BIOS quirks

I've had one of these cards in Dell Precision T5400 and T5500 Workstation systems since 2012, controlling RAID 0 arrays of four OCZ 480 GB Vertex 3 SSDs each.

At the moment I have two separate 4 drive RAID 0 arrays in a T5500 that boots up Windows 8.1 from one 2 TB array and runs several virtual machines (Windows XP, 7, 8.1, and 10) from the other.

It's hard not to get good performance with RAID 0, but this card has delivered ultimate reliability too. I haven't had even ONE glitch in the I/O subsystem, and I have run it continuously, without crashing, for 5 f.

Notably this controller card doesn't bottleneck very much the operations of two separate 4 drive arrays. While one array alone (per ATTO) will achieve about 140 MB / second throughput at 4k I/O sizes and 1.7 GB / second with large I/Os, when the test is run on both arrays simultaneously the small I/O rate is virtually unchanged, while the max I/O speed for the large requests only drops to about 1.3 GB / second.

If you're looking to bring a few years old system that only has SATA II (3 Gb/s) ports on the motherboard up to modern I/O performance levels, this card will delight.

The only problems I ever had were that I had to disable the motherboard's Intel RAID BIOS in order to get the system to boot up. Apparently there was some conflict between the motherboard RAID BIOS and the Highpoint on-card BIOS. But I'm still able to run the optical drive and several HDDs from the motherboard SATA II ports.

The only other complaint I had right at the start was that I did have to figure out what cable bundle to buy to control SATA III SSDs.

But after having installed the hardware it's been so flawless and delivered such good, responsive performance for so long that I can't really complain. This card has been quite a good value, considering I bought it when it was less than 1/4 the price of ONE 480 GB SSD.
