SEDNA PCI Express (PCIe) SATA III (6G) SSD Adapter with 1 SATA III Port (with Built in Power Circuit, no Need SATA Power Connector, Best for Mac), SSD not Included

When I received this card, I unpackaged it and secured a Crucial SSD onto the adapter. After plugging it into the slot and firing up the PC it wouldn't boot, AND the PC failed to see my other 4 installed drives installed drives. It couldn't get past this new card. Removing the SSD from the adapter allowed the PC to boot properly. I then installed the drivers for the card, shut down, and screwed a Samsung 850 SSD onto the card, connected the Crucial to the SATA port, rebooted, and both drives showed up in Windows Drive Manager.When it first refused to boot (with the Crucial SSD connected directly to the PCIe port I was ready to raise hell about the piece of junk that I was sold. After properly troubleshooting, though, I must say that this card works quite well - the only thing that seems to be negatively affected is the delay caused at boot while my BIOS recognizes this card - kind of "knocks out" my Fast Boot option. And - I may even be able to correct that. 4.78 stars...

I bought this card for my GNU/Linux RAID storage box to free up an extra SATA port as I am intending to install another 2 disk RAID array with the 2 free remaining SATA ports. This expansion card work like a charm, accomplished exactly what I needed and I didn't have to do anything extra in Linux to get it working! It is dead simple to install your SSD drive on the card with the four provided or your own screws and the drive slides securely into the onboard SATA data/power connection bridge. Highly recommend if you need to free up an onboard SATA port!Here are some specifications of my GNU/Linux Box:- AMD A8-3870 APU with EFI based motherboard (Note: Your motherboard BIOS/firmware should support booting from a PCIe device)- Intel 520 Series SSD Model # INTEL SSDSC2CW060A3 with the 400i firmware- Kernel -- Linux 4.10.1 based on gentoo-sources- OS -- Funtoo Linux - baselayout 2.2.1- Bootloader -- GRUB 2.02_beta3-r2

I needed this to open up a free slot on my Dell PowerEdge R710 server and plus wanted the SATA III 6Gbs speeds. The SAS/SATA controller I have now is SATA II so limited speed to 3Gbs. Easy to install (screws to mount SSD drive included). Server recognized it with no issues. Runs like a champ! Very fast and no issues what-so-ever. I may buy another for my PC. I have not done any tests on speeds yet, but definitely seems faster on file transfers than connecting to my old SAS/SATA controller. I would recommend this if you are needing to free up hard drive slots or if you have an older machine that doesn't have SATA III....

Using it to free up an SATA port for my custom built NAS. I have two boxes, this works flawlessly on one box but the other refuses to boot from it. All in all, great product. Mind you, both boxes are using the same chip, chipset and almost identical motherboard. It might be a BIOS issue.

Works in a Dell Poweredge R430 server running TrueNAS Scale.Has Linux support, but (from what I've seen) can only be run when booting with BIOS. Can't be run with UEFI.

Put this card in my NUC9 Extreme which has 2 PCIe slots. I put a TeamGroup 4TB SSD in the PCIe card then inserted to the x16 slot. NUC booted fine, drive shows up in Disk Mgt, and I was able to format / Use the drive without issue. This PCI card requires no extyernal cables or power, so you essentially just plug in a drive and plun into the PCIe slot and you are ready!

I had to return the first one I received. However, the replacement has been a reliable product so far, and I have been using it for three years now. I use these in my servers so that I'm not taking up SAS drive bays (at-home, personal/lab servers). I currently have it running in an R610 that is running VMWare 6.7u3 (also ran it on VMWare 6.0 previously). I believe I did have to use community supported drivers for this, but was able to install it just fine. The BIOS does recognize it as a bootable drive, though I'm not using it as such (you can install/run VMWare on a flash drive, which the servers have internal SD Flash and a USB port). I use this drive to run the VM Guest OS drives, and use the RAID SAS drives for storage. Hope this helps for anyone thinking about installing it in a server.Expected Speeds:A lot of people are throwing around bad speed info, including the description. This card runs on PCIe v2 supports 5GT/s, which is NOT the same as 5Gb/s as mentioned in the description. PCIe v2 x1 has a maximum of 500MB/s = 4Gb/s. SATA III has a maximum of 6Gb/s (=750MB/s). These are theoretical maximums. Even if you could get that full speed, you are bottle-necked at the 500MB/s PCIe2 speed; which is about 2/3rds of the SATA speed, and you aren't going to get that speed. This is why folks are showing screenshots running at about 400MB/s (=3.2Gb/s, which is about what I would expect to get). If you want faster, find a PCIe v3 card where x1 has a max speed of 985MB/s (assuming your motherboard is able to do PCIe v3). Note, PCIe is backwards compatible, but the card does not speed up to match (this PCIe2 card will work in PCIe3 and PCIe4 slots, but will run at PCIe2 speeds). If you find a PCIe v3 card you can run, then you will probably see actual speeds of about 600MB/s (assuming your SSD supports those speeds).

Did not make my ssd drive faster. SSD's worked better through the sata connection not through the pci express card
