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

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).

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!

Works as a boot disk on my 2012 Mac Pro. I have a Samsung 850 Evo which I also have on my 2012 non-Retina 15-Inch MacBook Pro. On my laptop my 850 Evo gets around 400 MBPs on Black Magic disk speed check but for some reason on my Mac Pro in one of the SATA slots, I only get 250 MBPs. This PCI card bumped my drive from 250 to 340 MBPs and freed up a slot for more storage. I don't know why my drives are slower on my Mac Pro than on my MacBook Pro from the same year but the disk speed tests show the proof. Ultimately this PCI card roughly gave me 50% more speed and freed up one of my drive bays for more scratch disk storage. *UPDATE* Since changing to this SSD I wasn't able to install Windows 10. Whenever I attempted to install Windows, whether I booted from EFI or BIOS, When I attempted to install Windows I received an error saying that it could not find the partition nor could one be created. I searched this error and discovered others who had it, but when I followed their troubleshooting steps, I was not able to get Windows 10 to install. I ended up moving my SSD back into one of the SATA ports on the Mac Pro, installing Windows + Boot Camp software and then moving the SSD back to this PCI card and it boots properly!

Easy to set up and is bootable on my motherboard, however the speed is slower than sata 6 gbps therefor it didn't benefit my ssd. My ssd was faster plugged into a sata port. Great for a mechanical hard drive or if you need an extra sata slot. Built in power is very useful though.

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.

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...

alles gut geklapt

Nice product with solid packaging, does exactly what you need. Second Sedna product I've bought and will buy again from them.

Great PCIe adapter, allowed me to add an internal bootable SSD drive in an old Dell server. Card seems good quality, needs no additional power connections (important in a server where there are none) and works as expected.

Didn't work with the QNAP TS-464 NAS - I spent about 10 hours searching for help, but nothing. Got a WWN error and the PCIE card seemed to map my raid onto the card. NO REPLY from the SEDNA HELP email address. Might be a QNAP linux config issue, but at this point it could be anything. Comes with a Win7 Driver on a mini CD !!!! What! No Windows 10/11 support - seriously was this shipped from a museum? TO SEDNA - PLEASE IMPROVE YOUR SUPPORT

I have an old (ancient in computer ages) MacPro 2009, which I upgraded to 3.33 GHz 6-Core Intel Xeon CPU and 32GB of memory, as well as adding a Mushkin 1 TB SSD (MKNSSDRE1TB). This is a workhorse that does what I need but this pretty much maxed out what I could do. The SATA speed in the drive bays for these Macs is limited to 3gb/sec. Putting the SSD into this PCIe adapter increased this to a full 6 gb/sec speed. With Blackmagic testings, I found there was a 38% increase in Read (up to 371 MB/s) and 29% in Write (up to 299.4 MB/s) speeds. So for the modest price of this adapter, I am quite pleased. Plus it frees up a space in the drive bay. I also tried the OWC version, and it was faster yet up to 450MB/sec, but it is more money.
