10Gtek SAS Adapter 2X Internal SFF-8087 to 2X External SFF-8088 Slot

Good working adapter for SFF-8087 (internal SAS2) and SFF-8088 (external SAS2) on empty PCIe slot. It could be installed properly in the PCIe slot with a full-height bracket. However, It cannot be inserted into the PCIe slot with a low-profile bracket (due to a wrong direction and length of the low-profile bracket included.) According to other reviews, it should be working fine with a low-profile bracket from LSI external SAS2 RAID controller, such as LSI 9286CV-8e. Because I had a bunch of LSI 9286CV-8e controllers from Lenovo SA120 units, I could use a low-profile bracket from it. With a LSI low-profile bracket it can be mounted in the low-profile PCIe slot as expected. Other cheaper adapters (with a small gap between two SFF-8088 ports) will not work with a low-profile bracket, even though we can use an LSI one. I highly recommended this adapter for someone who wants to connect internal-external SAS2 devices with a low-profile chassis, such as 2U servers.

I have ordered several of these and they were fine, but the last one I bought fell apart on me. It seems they don't bother to solder the legs on the port shields to the board, so when I pushed the connector in, it popped right off - see pictures. And to make matters worse, one of the legs is missing. Was it missing all along, or did it just break off and fall in my server? I have searched all over and can't find it, but it's tiny, so it could be right there shorting something on the motherboard and I won't know until something blows. Now I have to unrack the server, pull everything out of it, turn it over and blow a ton of air in there to make sure it's not actually in there. Thanks for that 10Gtek, that is exactly how I wanted to spend my afternoon. After this happened, I looked at the other 3 units I bought and found that none of those are soldered either, but at least they are glued on so they can't easily pop off.

As other commenters have mentioned, the SFF-8087 side is not soldered down and can easily be damaged or pulled out. The SFF-8088 side interferes with my SFF-8088 connector and case. I cannot get the SFF-8088 side to clip in and latch securely. Do not waste your money on this. I am only leaving 2 stars since it will hopefully at least function electrically long enough to get a replacement from a different brand.

It's a little more expensive than I'd like for what it is, however this adapter worked quite well for converting an existing SAS backplane chassis into a JBOD enclosure. My RAID controller had no problems detecting the backplane/drives through this adapter, and all features such as disk hot swap and drive locate worked fine. Unlike some competing products, there was no mounting issues or bracket spacing problems -- it fit into the case just like any normal expansion card might.

10Gtek Dual SAS SFF-8088 to SFF-8087 Adapter, with Low Profile and Full-Height Bracket Positive: The adapter itself works just fine Neutral: Oversized PCB prevents use of some right angle SFF-8087 connectors Negative: The low profile bracket is not as pictured in the listing, it's simply a shorter version of a standard bracket, and not mirrored like it needs to be. This was ultimately the adapter I needed, and really the only one I could find in 2025. So while it does work, I had to cut down the needlessly long PCB to fit the right angle SFF-8087 cables I had, and I had to mangle the half-height adapter in a vice so I could actually use it in my R720
