![]() ![]() The card appeared at POST, though initially it stated it couldn’t find a drive, turns out I hadn’t connected the power to the device, with that rectified the computer found it at full 6 Gbps.I had to initialise the drive in Disk Management (from Control Panel/Admin Tools/Computer Management) and was then able to format it. ![]() It’s easy to install, I used my x16 slot which is v2.0 compatible so gives the best performance (I’d read x1 slots are sometimes slower and you need v2 likewise), not that it was massively important.I installed on a Win 7/32-bit machine, installed the drivers off the supplied disk and rebooted. I was a bit nervous about this one as some of the reviews were iffy, but it was a good price and available through Amazon and not a third-party.It’s actually branded in an Iocrest box, but with a sticker stating Asmedia and their part number (and which the drivers are called). ![]() I looked at various makes and models from different suppliers and the prices of a 2-port SATA III card varied wildly. I was out of space on my media centre PC and out of SATA ports, so was looking for an expansion card. By loosening the screws and adjusting the card angle without bending, one can achieve a proper fit with the connections fully home in the slot. With a properly installed Syba card, the Samsung 840 SSD should achieve a maximum 7.9 score on the Windows 7 performance index.Some reviewers have experienced difficulty with the physical installation of this card. The setup is stable and gives consistent transfer speeds each time the tests are run. They may have been using the card in a type 1 PCI express slot, or they had not set their BIOS correctly for AHCI mode transfers. Cannot agree with some other reviews that this card is no better than the SATA II ports on older motherboards. Using SATA III (AHCI) ports on the Syba card gave improved transfer speeds of 394 MB/sec, 257 MB/sec, 52727 IOPS, 43910 IOPS. Read transfers should improve to ~500MB/sec on a new mobo with integrated SATA III ports but write transfer speed is already at the limit of the Samsung 840 SSD.Using Samsung Magician software, the SATA II port (AHCI) gave Seq Read, Seq Write, Random Read, Random Write figures of 263 MB/sec, 252MB/sec, 33443 IOPS, 30706 IOPS. With the Syba card installed, transfer rates using SATA III ports (AHCI) improved to 407MB/sec (Read) and 260MB/sec (Write). Using the ATTO disc benchmark for transfers of 1024KB to 8192KB, the mobo SATA II ports (AHCI) achieved 280MB/sec (Read) and 249MB/sec (Write). Fortunately the mobo has one PCI Express 2 slot which is necessary to get the most from this card. Bought this to equip my Gigabyte MA785GMT motherboard with SATA III ports to maximise transfer speeds with a Samsung 840 SSD. ![]()
