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

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.

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!

SEDNA PCI Express (PCIe) SATA III (6G) SSD Adapter with 1 SATA III Port (With Built In Power Circuit) works on my Mac Pro (2009) MacPro4,1 with macOS Sierra 10.12, 10.11.6, 10.10.5, 10.9.5, and 10.8.5. No driver needed. Bootable.It's okay but I don't recommend it if you want 500+ MB/s. I recommend the ones with PCIe 2.0 x2 (at least) such as OWC Accelsior S PCIe to 2.5" 6Gb/s SATA SSD Host Adapter which comes with the ASM1062 PCIe 2.0 x2 (10Gbps) controller.Pros:• Plug and Play.• No driver needed.• Bootable.• Better than the built-in SATA II (3Gbps). SATA II: 285MB/s read, 232MB/s write. ==> SATA III: 405MB/s read, 306MB/s write.Cons:• Uses the ASM1061 PCIe 2.0 x1 (5Gbps) controller. This mean you can't get the actual SATA III (6Gbps) speed. I have a Crucial MX100 512GB SSD which is supposed to be capable of 550MB/s read, 500MB/s write, but I only get 405MB/s read, 306MB/s write.• The extra SATA III port is nice but if you use two SSDs at the same time on the PCIe 2.0 x1 (5Gbps) bus, each SSD only gets 2.5Gbps (I assume) which is slower than the built-in SATA II (3Gbps).• The storage icon in Finder shows up as an orange "external" device.Note:• The device (and the controller) shows up under "Generic AHCI Controller" in the SATA/SATA Express section of System Information.

Since the Msata drive was failing, I purchased a similar card a year ago for an SSD drive in my Dell XPS Desktop. The old card required I connect power thus requiring another cable.THIS care does NOT require external power. Since I thought this was the same card I ordered prior, I ordered a power cable the next day, then, read reviews and found several reporting power was not needed. I always felt it would be better to have power and thought this one was "optional" yet I canceled the order for the cable. Saved $8. Card arrived and works flawlessly. Really helps not having to deal with any connections besides the PCIE slot. Love it. Boot from SSD and your jaw drops at the speed difference. Or in my case add another SSD and speed that old boy up!

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