Hard Drive Backplane Enclosure, Supports SATA I/II/III & SAS I/II 6 Gbps Performance - Image 1](https://m.media-amazon.com/images/I/51aXQ33+-5L.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Questions & Answers **Q: Does this support 3.5" sas drives? please don't answer unless you know the difference between sas and sata.** A: Though the Amazon Title says it supports SAS drives, if you go to the Kingwin website for the KF-255-BK, it says nothing about SAS, nor does the owner's manual pdf that I downloaded. I'd say it does not support the SAS connector configuration. http://www.kingwin.com/kf-255-bk-2/ **Q: Can 2.5" SSD be used with this mount?** A: Alone, No. Yes - With the addition of this Device: ICY DOCK EZConvert PRO MB982SP-1S Enterprise 2.5" to 3.5" SATA SSD & HDD Converter / Mounting Kit. This is what we use. Hope this helps! **Q: 2 HD sata cables. 2 power sata cables??? or just one?** A: 2 SATA cable. 1 SATA power cable. Be aware that the triangular key entry on the locking mechanism for the the 3-1/2" drive door is made of extremely soft pot metal and after a number of locking and unlocking cycles while changing drives in and out has deformed to the point where it's unusable even though I used extreme care once I discovered this problem it just continued to get worse, so now I have to leave it unlocked. The same key entry on the 2-1/2" drive door is made of stainless steel and does not suffer from the same weakness.This is a pretty serious defect in an otherwise very good product, and if there was something like this made by a competitor that didn't suffer from this weakness, I would try that by so far I haven't been able to find anything like it. I hope KingWin will correct this deficiency in future models. **Q: Will this kf-259-bk back plane fit a sas u.2 (sff-8639) connector?** A: Hi, Conscientious shopper, thank you for your question, KF-259-BK does not fit a sas u.2 sff-8639 connector, tks.
