Review on Yottamaster 6 Pack Hard Drive Mounting Bracket Hard Disk Caddy SSD HDD Tray Hard Disk Drive Bays Holder Compatible With 2 by Joshua Fuoco

I use this to store 5 backup drives. - Good Looks good and is well built Stays connected (USB connection doesn't drop) Good transfer speed (USB 3) Easy to install drives - Poor power button on the back making it difficult to turn on and off. Power/activity light on the back where it's completely useless For drives to spin up and be recognized by PCI, it sometimes takes about a minute to unplug and reinsert the USB cable for it to be recognized (or the hardware rescanned becomes). All drives are included together. I can't select specific drives to include.
