IO Crest SI-PEX40064 4 Port SATA III PCIe Controller Card (Green)

Easy to install. Worked perfectly with TrueNAS. Just plugged in and it works.

SHORTAGE OF SATA III ON MOTHERBOARD RESOLVED IN ONE STEP.SATA III PORTS ON THE CARD AS FAST AS THE ONES ON THE MOTHERBOARD.WILL RECOMMEND TO EVERYONE LOOKING FOR UPGRADING.

I purchased this and tried to install in my system, it just gets heated, doesnt work. It is useless. Dont buy at all

Outstanding product though chipset is old and windows 10 used standard storage controller

good

Hi this is ramesh Iam using this card. This is very good card.Iam using this card in windows 8.1

Very usefull 100% worth for money

GOOD

This does the trick perfectly well. I was limited to PCIe x1 for my NAS, and the particular chipset used on this card is highly recommended for TrueNAS.Can confirm, it picked it right up and all drives are still working perfectly, six months on.It's a bit expensive for what it is, but the majority of these on Amazon have an inferior chipset, and don't use PCIe 1x (usually 2x or 4x - even though they're not necessarily faster due to the SATA bottleneck).

After reading the specs of this card and talking to tech support at SYBA, here is what I understand.1. While the SATA ports on the card is capable of SATA III (6 Gb/s or 750 MB/s, where Gb = Gigabit and MB = Megabyte, and 1 Gb = 125 MB), the maximum speed of this card is limited by the 1 lane of PCIe slot, which depends on the version of PCI Express on your motherboard.2. PCI Express 2.0 supports maximum speed of 4 Gb/s (=500MB/s) for each lane. So the max speed of this card would be 500 MB/s. This is faster than SATA II (375 MB/s) but slower than SATA III (750 MB/s).3. PCI Express 1.1 supports maximum speed of 2 Gb/s (=250MB/s) for each lane. So the max speed of this card would be 250 MB/s. This is slower than SATA II.4. The 4 ports on this card share the same PCIe x1 lane. So if all 4 ports are in use, the maximum speed per port is 1/4 of the maximum speed given in (2) or (3).I have been able to confirm these conclusion by running the following experiment. I am using a Transcend SSD370 512 GB drive, which is advertised to have max read/write speeds of 560/460 MB/s.To test this SSD's speed, I plug the SSD into an ASUS P8Z77V-LX motherboard, which has both SATA II and SATA III ports.In the SATA III ports, the max R/W speeds are 504/457 MB/s, as measured by CrystalDiskMark 3.0.1In the SATA II ports, the max R/W speeds are 275/262 MB/s.Now, I plugged the SSD into the PEX-40064, and put it into the PCIe x1 slot, which is compatible with PCI Express 2.0. The max R/W speeds are 385/286 MB/sSo, the PEX-40064 is capable of delivering a higher speed than SATA II, but far from SATA III (read on if you have PCI Express 1.1).I ran the same tests on an older motherboard -- Gigabyte P35-DS4, which has only SATA II ports and supports PCIe Express 1.1In the SATA II ports, the max R/W speeds are 260/254 MB/s, similar to those in the SATA II ports of the newer ASUS board.I then plugged the SSD into the PEX-40064, and put it into the PCIe x1 slot of the older P35-DS4 board: The max R/W speeds are 202/168 MB/sIndeed, the PCI Express 1.1 slots are slower than the PCI Express 2.0 slots and the SATA II ports.Conclusion: Where does this leave us?-If you have a motherboard that has SATA II ports (but no SATA III ports), and you have PCI Express 2.0 slots, then you can use the PEX-40064 card to get a faster speed (if your SSD can achieve it) but you will not get close to SATA III speeds (even if the SSD is capable to achieve it).-If you have a motherboard that has SATA II ports but no SATA III ports, and you have PCI Express 1.1 slots, then you are better off using the SATA II ports than the PEX-40064 card.-If you are using the older magnetic spin hard drives (HDDs), then this discussion is not relevant. Most of my HDDs rarely achieve sustained R/W speeds above 100 MB/s.-In my experience, the PEX-40064 card tends to freeze up in the PCIe 1x slot when I transfer large amounts of data (more 10 GB). But if I put the PEX-40064 card into a PCEe x16 slot, I rarely encounter freeze up. I don't know how to explain this, since the card uses only 1 data lane, regardless of how many data lanes are available in the PCIe slot. I ask tech support about this but I did not get an explanation.Hope all of this is helpful.AFTER THOUGHT: To get faster than SATA II speeds for motherboards with PCI Express 1.1 slots, here is what I would do. Switch from the PEX-40064 card (which uses 1 PCIe lane) to the PEX-40054 card (which uses 2 PCIe lanes). This turns out to work !! The Transcend SSD370, plugged into a PEX-40054 card in a motherboard supporting PCI Express 1.1, has the following max R/W speeds: 373/285 MB/s. This is almost the same as the PEX-40064 card with PCI Express 2.0. The only downside is that the PEX-40054 works in a PCIe x4, x8, or x16 slot, but not in a PCIe x1 slot.SECOND AFTER THOUGHT: It is possible to achieve close to SATA III speeds in a motherboard with PCI Express 2.0 slots with more than 2 data lanes (e.g. x4, x8, or x16) with the PEX-40054 card instead of the PEX-40064 card. For the Transcend SSD370, the max R/W speeds are 479/458 MB/s, very close to the speeds of the SATA III port in the new ASUS board.

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!

fait le job, sans plus.

This is for the 4-port Marvell 88SE9215 card.The box includes the PCB, an alternative PCI bracket for smaller form factors, two SATA cables, and a CD with drivers (for Windows I assume).Was simple plug and play on my Linux server. Identifies as "SATA controller: Marvell Technology Group Ltd. 88SE9215 PCIe 2.0 x1 4-port SATA 6 Gb/s Controller (rev 11)". Works well but seems to be limited to around 200 MB/s read/write, about 190 MB/s sustained. It is plugged into a PCIe 2.0 x1 slot, which in theory should support ~500 MB/s. This is with the following scenarios: Copying to a drive connected to the card; copying from a drive connected to the card; copying to a drive connected to the card and writing to a drive also connected to the card. All scenarios are 200 MB/s. The SATA link is reported as 6.0 Gbps.So it will work okay for HDDs (although they can usually go above 200 MB/s these days too), but for SSDs you'll leave a lot of performance on the table.Overall I'm happy with it though.
