The SA3006 6-port SATA card looks good on paper, but once you start actually using it, there are some serious problems, at least with the SA3006 card I received.Problem #1: All drives attached to the card appear to Windows 10 as removable drives, even if they are all internal drives. I did some research on this, and found that it is typically a card BIOS issue. I spent a lot of time looking into a variety of solutions, including updating the card's BIOS (couldn't), using different versions of the driver (newer and older), making configuration changes through Device Manager, and making configuration changes directly to the Windows registry. None of the solutions had any effect at all on the problem. All drives continued to show up as removable. So, a user can effectively disconnect these internal drives directly through the Taskbar. This behavior might be okay on an enthusiast's workbench, where the user just knows not "eject" these internal drives, but this behavior is unacceptable in virtually any business office, server room, or classroom environment. (The seller was initially enthusiastic about helping to resolve the issue, asked me for a screen shot, and then fell silent for days.) There is no documentation with the card, and there doesn't appear to be any way to update the card's BIOS.For me, this "all internal drives are always removable" card behavior is a deal-breaker, but read on...it gets much worse.Problem #2: After restoring the registry to undo the changes described in problem #1, and after using the card for a few days, the attached drives started to disappear randomly. At one point, all drives had disappeared on their own, with no human intervention. Restarting the system cleared the problem temporarily (all drives appeared as attached, and as removable as described in problem #1), but after a few hours of using the system, individual drives started to disappear again on their own, until all attached drives had again completely disappeared. In one case, one of the drives disappeared while it was being written to, causing file corruption and lost data.So, all drives attached to this card can be disconnected by the user using the Taskbar, and if the user doesn't do this, the drives eventually disconnect themselves at random times, including while they are in use. I have been working with computers, including build and configuring desktops, workstations, and servers, since the 1970s. I've worked with a lot of disk controllers/adapters over the decades, and this is one of the flakiest cards I've ever encountered.All attached drives are known working, and only exhibit this behavior while they are physically attached to this SATA card.On the plus side, the box includes a small screwdriver, a low-profile bracket, a mini CD containing drivers for this and many other cards, and a little printed card offering a "40% payback" for posting an Amazon review (a violation of Amazon seller policy). To be clear, I am NOT getting compensated for this review. Even with a 40% rebate, the card is not worth it, if you value your time and your data at all.I am returning the SA3006 card. Life is too short to spend any more time with it. You've been warned.

I am installing multiple hard drives with a motherboard with only to SATA connections. This card allowed me to connect 4 additional hard drives and it is working really well. Payback 40%

Those who having a disconnection problem, to stop this you need to disable (VT-d) in the bios if your motherboard support it.

I have a six year old motherboard in my PLEX server, it has four SATA 3 ports and four SATA 2 ports. I thought I was buying new tech as it runs a six core I7 processor with 32 GB's of RAM. I had run out of SATA ports for internal HDD's so had purchased a four port PCIe card to add more drives. As I booted the machine one day I realized that four of my drives were only running at 3.0 GB/s. As I am striping the majority of the drives into sets of two, this was leaving me very close to the choking my throughput. With the addition of this 6 port card I can move the four drives off the SATA 2 ports and still have two more ports for additional drives.

I needed this card because after connecting a NVME drive to my motherboard it disabled 2 of the SATA ports on the motherboard.This SATA III 6-Port Adapter Card is much better than I expected at this price point. Install was simple, inserted it into a PCIE x4 slot PC recognized it right away. Booted into Windows 10, and the drivers were installed automatically. Shutdown the PC, connected 3 8tb drives rebooted and Windows could use the drives. Read and Write speeds are excellent from the 3 Seagate 8tb SMR drives I am using with this card.Note - I did have one problem but unrelated to this card, my Gigabyte MB needed a BIOS update to allow use of more than 5 drives, if you have a similar problem check if there is a BIOS update available.

This review is for the Ubit PCIe 2.0 X2 to SATA III 6-Port Adapter Card.I have a Fresh install of CentOS 8 and this device does not work.In the box there is a piece of paper with an "Installing Guide and driver" QR code this does not work on either of my phones with any QR Code scanning app. On the same card it says to email to get 30% off for a written review... I've emailed this email for support and they do not support Linux despite the product description saying they do.The website (the email address without the who@ part) goes to TestPage184, so that's nice.there's a CD with all kinds of Windows drivers on it but the listing says that you don't need drivers and it works with Windows and Linux.update - I was able to get this device to work, support will only help with windows and were unwilling to help me.This device fails when put under load. I was having read errors every couple hours with my new disks so I was testing to see what it might be and everything attached to this failed.
