IO CREST 24 Port SATA III PCIe 3.0 x4 Expansion Card - JMB575 & JMB582 Chipsets - Non-RAID Support - Low Profile Bracket Included (SI-PEX40169) - Perfect for Data Storage Servers & PC Builds

For my intended purpose this is ridiculous. So cheap for exactly what I was looking for. I have several hard drives and disk drives and ran out of SATA ports to use on my mother board (only has 6). Was looking for a adapter that would make use of my unused pci-e 2.0x1 slots on my board (or even the pci-e 2.0 x8 and x4 slot since I only run 1 video card these other ports just collect dust) but give me more SATA ports. This fit the bill perfectly and for much less than several other brands adapters on the market. Not only do you gain 4 SATA III(6gb/s) rather than most other adapters only give you 2 SATA ports and are not always SATA III. I followed instructions but if you are even slightly schooled on computers and computer parts you could just guess what to do fairly easily. Unhook everything, power cord disconnect and install the card in the pci-e 2.0x1 (or x4 x8 x16) or pci-e 1.0x1 (or x4 x8 x16). With the pci-e 1.0 it will just run at half the speed if you have an ancient board but is still compatible. Also I didn't seem to find anywhere in the description about the SATA cables so I ordered some.... It comes with 2 and they are both SATA III capable. I had no issue with the drivers, didn't even need the disc. windows 7 x64 recognized the device and downloaded them.FOR PEEPS WITH WORRIES ABOUT POSSIBLE COMPATIBILITY PROBLEMS- This is my system setup and install and use went without any issues. (I doubt there should be any unless the pci-e slot you are trying to use is malfunctioning on the Mobo....)--Intel I5-2500K (Sandy) Processor--EVGA Z68 ATX DDR3 2133 Intel - LGA 1155 Motherboards 130-SB-E685-KR--EVGA GeForce GTX760 FTW with ACX Cooler 4GB GDDR5 256Bit Dual-Link DVI-I DVI-D HDMI DP SLI Ready 04G-P4-3768-KR--2x--Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX--Windows 7 Home Premium SP1 64bit (Full)--Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW--Western Digital 500GB and 1TB Blue HDD (7200rpm) SATA III---Pioneer Electronics USA 15x SATA Internal BD/DVD/CD Burner with 4 MB Buffer BDR-208DBK--Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive (Black)I have swapped all my HDD's, SSD, and Optical drives to this adapter and ALL OF THEM WORK on ALL SATA PORTS.SO to sum up..... This thing is an absolute STEAL if you are trying to make use of some pci-e 2.0 or 1.0x1 slots and would like some more SATA ports :)I actually may buy another one of these in case my motherboard SATAs decide to fry and then I won't have to get a new motherboard.I hope this helps you in your decision, if you have any questions or comments please ask!
