Are you thinking about installing an ultrafast RAID array, but you either have a laptop, don't want to open up your PC, and/or don't want to mess with drivers and complicated configurations? Monoprice has the answer to your needs in the form of this 2-bay 3.5" HDD USB 3.0 RAID Enclosure!
This RAID enclosure is perfect for increasing data throughput speed using the RAID 0 striping mode, for increasing data security using the RAID 1 mirror mode, or as an easy way to add a pair of external drives using the JBOD "just a bunch of drives" mode. It supports two 3.5" SATA II (3.0 Gbps) drives up to 3TB each and has even been tested with the latest Hitachi 4TB drives for up to 8TB of storage using the RAID 0 mode.
This aluminum enclosure is completely self-contained, with everything needed to connect to a Windows, Mac, or Linux computer using a USB cable (included), except the drives themselves, of course. It has a built-in 70 watt power supply, which provides 12 VDC and 5 VDC power levels from any 100 ~ 240 VAC power source and a 60mm fan to keep things cool.
It features an energy (and drive) saving standby mode, which is automatically activated when the connected PC is put into "sleep" or "standby" mode. Drive installation is made easier with the ability to hot swap drives in and out of the system without turning off either the enclosure or the connected PC. Most importantly, it contains all the controllers, drivers, and software needed to operate and maintain the RAID array, making RAID installation and configuration as simple and easy as it can possibly be.
