The AdaptaDrive 2.5" to 3.5" Drive Converter Bracket from Newer Technology enables you to install a 2.5" hard drive or SSD in a 3.5" SATA drive bay. This bracket features a circuit board bridge adapter that supports SATA III interfaces. By offering a bridge adapter with this bracket, you can easily install a faster 2.5" drive to the backplane tray in Mac Pros. This adapter delivers direct pass through performance so your SATA III drive maintains its 6 Gb/s transfer speed without any slowdown from bottlenecking or performance throttling. For supporting drives with slower SATA speeds, it is also backwards compatible with SATA II and SATA I interfaces. In addition, the aluminum converter bracket features an open design, which allows your cooling system to provide cool air to flow around the drive.
