Suitable for installation in slimline or small form factor computer cases, the PEXSAT31E1 offers a dual profile solution, including a low profile/half-height bracket for easy installation.

4 out of 5 eggsWorks in linux server but not as expected

Pros: - Works in CentOS 5.8
- Performance is increased by 30% in single dock station with 6Gbps and 4k sector size drive

Cons: Expected twice performance improved based on 3Gbps to 6Gbps speed change but only 30%. But, this is still good.

1 out of 5 eggsNot compatible with HP servers?

Pros: cheap

Cons: Does not work on HP DL380G5 using server 2008 R2 x64. Server reboots at loading file "crcdisk.sys" . Appears to use a Marvell 88SE9123 controller so this might be a problem for any vendor using that controller. Device info:

Vendor ID:1B4B
Device ID:9123
BIOS Version
Firmware Version:
PCIe Speed rate:2.5Gbps
Configure SATA as: AHCI Mode
Supported Mode: RAID0 RAID1

Other Thoughts: It would be nice if StarTech or Marvell (or both) kept a known incompatiblity list. Its the least they can do if they're not going to address compatibility problems (or if the problem is with HP instead of Marvell).

1 out of 5 eggsDid not work

Pros: -None

Cons: Same result as previous poster. Tested on HP ML370 G5. This card caused Windows parity errors and was not usable. Updated firmware as suggested by support however they acknowledged that this is a known issue and recommended an older model card.

1 out of 5 eggsNOT for servers

Pros: None for our purpose

Cons: Does not work on an HP Proliant DL360 G5 server.
Gives a "NMI: Parity Check / Memory Parity Error" when inserted.
We bought these cards in order to move data from/to the server rapidly. They simply do not work- insert the card, get the error, remove the card the error disappears.
