SATA Card PCIE 3.0, 4 Port with 4 Cables, Controller Expansion Card with Low Profile Bracket, Non-Raid, Boot as System Disk, Support 4 SATA 3.0 Devices

Very good item.

I had an 8-port SATA 3.0 card. It came with drivers but didn't explain which version of the two sets of drives that came on the CD. Anyway, Windows 10 found some drivers for it and it worked for the most part. I still had an issue with the fact that all of the hard drives on this card showed up in Windows 10 as removable/portable drives, which was a pain. Each one could be ejected even though they were installed inside my PC. However, my motherboard as 10 sata ports on it and two sata controllers, which two ports on the second sata controller. Those two port also showed up as removable/portable drives, even though they are installed inside the PC. After a lot of searching on the internet for a solution, I finally found a registry mod that would allow those drives to be set to not show up as portable in Windows 10. That worked for the ports on the card, but the two ports on the motherboard didn't work. So, for those, I tried to update the BIOS in the computer. Unfortunately, after doing that, they computer would not longer boot up with the 8-port sata card installed.That lead to me getting two of these 4-port cards. My computer boots fine with these and I know have 8 extra sata drives installed in addition to the 10 sata drives on the motherboard (only 8 of these are hard drives, the other two are the boot SSD and a Blu-ray player). What I like about this one this that no driver is needed. I will install a third one today and stop using those two sata ports on the motherboard that result in the two drives showing up an portable, ejectable drives in Windows 10.For anyone having similar problems with Windows 10 Pro showing your sata drives as portable/ejectable drives, there is the solution I found on the internet:I had the same problem but only had one drive. I found this in another forum and decided to save it.If Kbird's solution does not work try navigating to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\storahci\Parameters\Device in the registry. Once you are on the Device Key, In the right hand plane, right click and create a new Multi-String Value Name the new value TreatAsInternalPort Double click the new value to edit it. In the Value Data section, start with 0 then 1 2 3 depending on how many ports you have. The trick here is they must be numbered vertically. The value data section will look like this:01234567891011The example will work for twelve ports.It is important that you add a separate line for each port. This what I 'm using on Windows 10 Pro version 1809. Also, this is a registry edit so DO NOT DO THIS if you are not comfortable doing registry edits as this kind of thing could potentially trash your computer. Backups should be made first. Obviously, someone with nearly 20 SATA devices is probably not going to be a computer rookie. :)

This product is fantastic and worked for me right out of the box, even with an older motherboard. I noticed that my server kept freezing and crashing while recovering my RAID NAS with a new drive that I finally had space for thanks to this device. I looked back at the listing here on Amazon and saw that it strictly stated that it was not PCI compatible, only PCIe. I had an open PCI to PCIe adapter in my PC that works for other devices, but it clearly does not work for this so keep that in mind.Overall, the device works great and I love the red indicator LEDs to show data passing through each hard drive that is plugged into it.

I've tried two different ASMedia 1064 based 4 port cards like this one. I prefer the IOCrest/Syba version of this card as it's a more reputable vendor but they both use the same ASMedia chip so there's likely not much difference except perhaps in the build quality. This version has a heatsink on the ASMedia chip which is kind of useless as even the non heat sinked versions don't get very hot even under heavy use.There are some important differences to be aware of with SATA PCIe cards like this one. First, ASMedia chips tend to be much more compatible across a wider variety of operating systems than those using JMicron controllers. In fact there are lots of well documented issues with JMicron SATA controllers especially under Linux or for NAS use.If you opt for a high-end SATA controller, like those from LSI Logic/Adaptec/HP/Dell/etc, beware they run hot and use a bunch of power while offering no real performance advantage over the ASMedia options in most applications. SATA hard drives are limited to around around 500 MB/sec and the ASMedia 1064 can easily run at those speeds so anything more seems like overkill.ASMedia chips are often used on many motherboards that offer more SATA ports than the CPU/Chipset natively support. This is one reason why ASMedia is natively supported in most Windows versions and Linux distros with no added drivers needed. I can confirm the ASM1064 works great with Windows 10, Win 11, any version of Debian/Ubuntu based Linux from the last several years, Unraid, OpenMediaVault, Proxmox, etc. And it does so while using very little power.I'd suggest doing your research and see if you can find the IOcrest or Syba version of this board. They're often around the same price and have much better support.

I used this in a machine so I could make a TrueNAS machine. I was able to plug it in and connect the drives and the machine immediately recognized all of the drives without any additional configuration. I appreciated the included SATA cables and the extra bracket in case I need to install it in a small form factor. Very pleased with this card and would absolutely buy another if the need arises.
