How does the FireFly SATA compare to the UltraBlock SATA?

The FireFly SATA bridge is an ultra-compact forensic bridge for use with SATA hard disks. To make the FireFly as small as possible, there were several features removed that the UltraBlock has. Namely, the FireFly lacks a USB host interface, power switch, dual power supply options, host detect, and drive detect LEDs.

Even though the FireFly has fewer features that the UltraBlock SATA bridge, the FireFly achieves imaging times comparable to the UltraBlock and retains key UltraBlock features such as the write block, activity, and power LEDs and configuration switches. Moreover, the FireFly connects directly to the back of the SATA hard disk, eliminating the need for a SATA signal cable. And, if the SATA hard disk has a SATA-style 15-pin power connector, the FireFly powers the hard disk directly, further eliminating the need for a power jumper cable.
