Review on 🚀 Enhance Data Transfer with Ableconn PEX-SA134 4-Port eSATA III 6Gbps PCI Express Four Lanes Host Adapter Card - AHCI Port-Multiplier PCIe 2.0 x4 Controller Card by Paul Ajayi

Please note that these cards require a PCIe 2X slot or higher. For many computers, this means using an additional PCIe graphics card slot. I tested a few of these Ableconn cards on two desktops for over a week. These cards attach to removable SATA hard drive cages. Using these cards, I cloned over 12 terabytes of data from each computer's internal hard drives to back up the hard drives. I didn't have a single problem, although some clones took over 12 hours. In other words, I ran these cards through the dialer as a test. I performed SMART checks on the target disks both before and after all operations. Not a single problem! I can't say the same for the other two brands of controller cards I've tried over the past month. Another brand of SATA controller card (with the Asmedia chipset) caused a whopping 17,358 Ultra DMA transfer errors and thousands of drive head software load/unload cycles on a single replacement hard drive. I tested the same backup disk with the new Ableconn controller card. None of the SMART scores increased by even 1 (one). Apparently the problem was with the Asmedia chipset in a different brand controller card. Asmedia pleases Google when it comes to SATA chipsets and USB3 chipsets. Google results don't paint a pretty picture for Asmedia. Even more interesting is a look at the Asmedia website. There are no drivers. There is no support. I have tried cards with the Marvell 9215 chipset and found that these cards only connect to SATA 1.5G speeds in Windows 7. The solution to this problem was to uninstall the maps and then immediately reinstall them in Device Manager. In this case, cards with the 9215 chipset switch to SATA 6G speeds. However, this is not possible if your operating system's hard drive is connected to the card. I also tried cards with Asmedia 601x chipset. The Asmedia chipset was causing the Ultra DMA error and other errors described above, and this Asmedia chipset was also causing the attached hard drives to magically spin down during backup or cloning operations! Not exactly stable. As a result, these Ableconn cards with the Marvell 88SE9230 chipset (also sold by Startech, a company that's picky about what they sell) are reliable. Again, note that these cards require a PCIe 2X slot! Other SATA controller cards with the Marvell 9230 chipset and a PCIe 1X slot (readily available on most computer motherboards) should also be reliable - as long as the rest of the card is of decent quality. Please note that a PCIe 1X card with the Marvell 9230 chipset has slightly lower performance than a similar card with the same chipset that is a PCIe 2X card. If you have a free PCIe 8X or 16X slot, then either this proven Ableconn card or an identical Startech card will do.
