Your cart is empty.The IO Crest 2 Port SATA III PCI-e 3. 0 x1 card ( SI-PEX40148 ) is the easiest way to update any computer with SATA ports with a PCI-e x1 slot or larger. Once installed¸ this host card will add SATA ports with two independent channels. This allows support of two SATA devices at speeds of up to 6Gb/s whether it is a SATA hard drive or SATA device. Using the JMB582 chipset, the SI-PEX40148 can provide a maxium sequencial Read / Write Speed of 850 MB/s to 2 SATA 6Gb/s ports. For the storage solution based on data transfer of multiple hard drives, the newly added FIS-based switching design can overcome the bottlenecks created by operating multiple SATA storage devices simultaneously.

Great solution for quickly adding sata drives to your system. Immediately detected by Proxmox and works without issue at the expected speed.

This product works. However, It didn’t perform as advertised. The transfer speed was slower than advertised.

I needed to add two additional drives into my UNRAID server but only had 4 headers on the motherboard. This was plug-and-play and was detected by UNRAID as soon as the booted the system up after installing it.

I'm running an Unraid server and I plugged two HDDs with this card, at first it was fine, after 2 months both of those drives started disconnecting randomly, maybe when they were both active idk, whatever is the case, this card proved useless, wish I could return it, replaced with another cheap card and so far so good.

Pros:1. 2 extra sata port for sata devices.2. When using one port only, the speed is very close to the onboard sata port.Cons:1. first one arrived DOA.2. when using both ports simultaneously, even the 2nd one is a DVD Burner, the transfer rate dropped to 40mb for the HDD.3. Even though it's internal card connected to internal devices, windows 10 shows the devices as removable. so have to be very carefully not to eject them accidentally.

This works well in Windows 10. Drivers automatically installed before you get to the desktop.You will get the full speed of the PCIE Gen3 x1 interface which is the bottleneck here when using the 2 ports simultaneously. What I mean is that to truly feed the 2 SATA ports, you would need about 10gb/s on the PCIE bus slot (meaning an x2 slot would be needed). Here on a PCIE x1 slot, one SATA port gives full speed 530-540MB/s, but if using both (aggregate or striped/RAID0) you do not get the desired 1000MB/s+, you are instead capped at around 900MB/s - because a PCIE x1 port can only do 8x1000^3 bit per second, aka ~8Gbits/sec.The important thing here is that the advertised Gen 3 support is true, it is not limited to Gen 2 as many of these 2 port cards are. This card delivered all it can on the PCIE x1 slot, so all is good!Attached are performance tests with 1 Samsung 950 Pro 512GB drive (left side) and with 2 drives striped (right side), for ASS-SD, CrystalDiskMark, and a simply 1GB (file per frame) AJA test. This should answer all questions. This card is a rock solid PCIE x1 GEN 3 card!Test platformWindows 10 ProASUS Strix-E z490Intel i9 10900K64GB DDR4This card in the farthest from CPU PCIE x1 slot. All other slots are jammed full with NVMe direct to CPU (10500GB/s) and through the PCH z490 chipset. This PCIE x1 slot is on the PCH chipset (the usual x4 Gen 3 DMI 3.0 limit) but no other significant I/O is being used.

Building new Ubuntu computer, needed a couple more SATA ports for hot swap drive bays. Two other cards failed to work with Ubuntu, recognized that there was an HDD but couldn't access it even to do a new partitioning. THIS CARD DID IT. Recognized the drives, one of them 8TB, allowed repartitoning, allowed mounting and reading and writing data. Just the way it's supposed to work. Don't trust the ASMedia or Marvell chipsets to work with Linux. Both failed on previous purchases. This one I don't have to return.

Works fine. Plug and play with Win10. Very boring. Very bright LEDs though ;}

Card works great, using it with unRaid and no issues at all. Be sure to put it in a PCIe 3.0 slot though. I had it in a 2.0 X1 slot and was only maxing out at 125MB/s on my parity sync with two disks connected to the card. I moved the card to a 3.0 X16 slot and now I'm getting 150MB/s with those same two disks connected which is the maximum read rate for those HDDs.
