The BPU-340 is touted as a "Military Grade" hot swappable hard drive enclosure by iStarUSA. The enclosure features a solid aluminum body and bays to dock up to for standard sized 3.5-inch SATA or SAS hard disk drives. The rear contains four SATA connectors, two SATA power connectors and two Molex power connectors. Either of the two power options will work depending on your power supply (eg: you can use two SATA power connectors or two Molex connectors). Also on the back are a set of DIP switches to disable the hard drive activity LEDs on the front of the unit as well as a switch to control the speed of the on-board fan ranging from low to high settings. There are header pins to set the thermal alarm between the ranges of 55, 60, and 65 degrees Celsius and LED pins for power, reset and other functions which would likely be utilized by OEMs.

The design is a basic silver aluminum chassis that will fit in three contiguous 5.25 drive bays. On the front of the unit are slots for up to four hard drives. The drives are mounted to drive trays which are included with the main chassis and can be locked into place with a very basic slotted design which would be very easier to overcome, so don't count on this locking mechanism to truly secure your drives.

Also on the front are buttons to turn each drive on or off independently. This could be a handy or disastrous feature depending on if you have your drives in a RAID configuration. The front comes off as feeling very plastic-like which goes against the whole "Military Grade" description.

The BPU-340 retails for about $75 at most online merchants with separate drive trays selling for an additional $45.

The BPN-DE Series enclosure is just ahead.
