The 4TB NT2 U3e External Enclosure from Akitio is a RAID capable 2-bay storage system for connecting to Windows or Mac systems. Two pre-installed 2TB hard drives can be set in various RAID configurations with the hardware RAID controller. Having a dedicated RAID controller allows you to use this RAID array on more than one computer. Configuring the drives in RAID 0 will offer the storage systems fastest transfer rates of up to 250 MB/s. If preserving information is more important, you can set the drives into RAID 1 that will create an exact copy of data on two disks. Each bay can accept a 3.5" SATA hard drive for future upgrades or replacements without the need for any tools. On the back of the NT2 U3e are USB 3.0 and eSATA ports for connecting to your computer. To cool both drives, this system is built with aluminum to dissipate heat for passive cooling and a 4,000 rpm fan for active cooling. Along with the storage system are a power adapter, eSATA cable, and USB 3.0 cable.
