Very Poor Design, Manufacturing and Handling6/7/2014 10:49:15 AM

Pros: I am sure many, if the device worked, and had not been mishandled during manufacturing.

Cons: Firstly, this supposedly brand new item arrived to me physically dirty. The actual physical device, obviously after being taken out of the package, was dirty. Some sort of grime, along with sticky fingerprints were all over the back and components of the card. I cleaned most of it off with some methanol, but the fingerprints and a film of some kind remain. Secondly, the internal SATA power socket on the card itself is, or rather was, attached to the PCB with very flimsy and tiny plastic mounts. Upon the very first insertion of a SATA power cable these mounts snapped. Now, the socket is being held onto the PCB only by the copper leads themselves. I have over 15 years of experience with electronics and computer hardware, so I certainly know what I am doing, and did not over-exert any force. Thirdly, this card BSODs my Windows 7 Ultimate 64-bit system any time a device is plugged into it. The following is the last BSOD overview I captured before writing this. If you search the codes, you will find they all point towards faulty hardware: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Additional information about the problem: BCCode: 50 BCP1: FFFFF880033BE000 BCP2: 0000000000000001 BCP3: FFFFF880081BAECD BCP4: 0000000000000000 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Lastly, with this card installed in my system, if I try to hibernate or sleep, Windows will fail to resume and report a corrupted restoration point. To resolve this, I have to reboot twice, delete the restoration point, and start Windows fresh. I am not at all a satisfied customer, and find this product to be faulty, containing poor design features and component quality, and showing signs of poor handling and manufacturing.

Solid Card, Great Buy4/4/2014 8:59:44 AM

Pros: This card has a solid physical design, and the inclusion of low-profile mounting brackets means you can use this is thin client, and 2U+ rack cases. I am using the card to host an external backup drive, and an internal backup drive. Solid performance, no issues at all. For those having issues with the drivers, make sure you get the Marvell 92xx drivers from Marvell's website. In Device Manager the the files are listed as mv91xx.sys, mvxxmm.sys, and mv91xxm.dll. In regards to device compatibility, I have had no issues testing SATA I, II and III hard drives. As well, no issues with either DVD-RW or BR-RW drives, single and dual layer. Booting from all devices works fine, but this is actually dependent upon the motherboard BIOS.

Cons: There are a couple of items that buyers need to be made aware of: - Firstly, this card is requires a PCI-e x4 or larger slot. It will not fit into x2 as the description indicates. - Secondly, this card has four SATA channels, that means only four of the six ports are usable at once.

Overall Review: This is a great card, with solid compatibility and performance. I have never bought a bad Vantec product, and they are one of the few brand names I inherently trust.
