Fits the bill-works well

By: charlie1939 - 07/13/2015
Just installed my first SSD, 250GB Crucial BX100, using this adapter, part no. BRACKET25X2, which included 2 SATA cables and a SATA "Y" power cable for two drives as well as the 3.5 inch to 2.5 inch adapter. The part is not only well designed, fitting the SSD perfectly, but included all the hardware to mount two 2.5 inch SATA drives in the 3.5 inch "floppy drive" slot on my old Dell Optiplex 755. Only issue was the four fiber washers that would not fit: being concerned that they were necessary, I called Tech Support and wonder of wonders at 3:30PM EDT an agent picked up the call after about a 1 minute wait! All I can say is that I will not hesitate to buy more StarTech products if this one is typical of the rest of their product line.

Good bracket for mounting your Solid State Drives

By: bricks - 10/21/2020
Just got this from a retailer to mount 2 SSD SATA 2.5 inch drives in my desk computer. I didn't need the SATA cables this time (they were replacement drives) but the split power cable was useful. I didn't know what to do with the fibre washers in the bag of screws so went on line to the tech support chat and quickly sorted it out (basically use them if needed). Excellent product. I have been using Star Tech products for quite a few years.
