The BPU-340 and the BPN-DE series that we are taking a look at today are two different hard drive enclosures that allow for easy hot swapping of hard drives in and out of a chassis. These are quite simple units in design but offer functionality that few vendors out there provide. Both enclosures allow up to four SATA drives to be docked to a computer and easily removed. This is helpful to people who may have RAID arrays or otherwise highly available storage volumes in their PCs or home file servers.
Both of these enclosures are designed to fit in a computer case with three contiguously open 5¼” bays available. They may not fit in some cheaper cases that have metal tongues that divide the drive bays but will likely work just fine in any quality full-sized ATX case. By design, iStarUSA instructs that both enclosures should be installed internally, but it is worth noting that it is also technically possible for them both to be used as external enclosures. This is assuming you can come up with the correct power supplies and SATA convertors. As the enclosures have SATA connectors, using them outside of the case may require eSATA to SATA convertor cables. You will of course also need a power supply, but I digress.
With that said, let's move ahead and take a closer look at the BPU-340 and the BPN-DE series hard drive enclosures.
