Sans Digital TowerRAID TR4M 4 Bay SATA to eSATA Port Multiplier JBOD/RAID 0, 1, 1+0, 5 Enclosure (Silver)
This is a 4-disk enclosure that attaches to the computer via eSATA. It comes with the PCI card for your desktop and the software. All you need to do is add SATA drives, up to four. You can configure the unit with RAID 0, 1, 0+1, or 5.
I am selling it because I moved to a large Drobo.
Retails new for
$150 from Amazon. Priced for quick local sale of
$75, including the enclosure, PCI card, power supply and provided software. Works fine, or your money back.
Here is the description from the manufacturer. My unit is the same by silver, and I think it's the previous model. It seems exactly the same except for the color. I am still using one of these (USB version) and it works fine with four drives.
The TowerRAID TR4M-B is a compact RAID tower utilizing the latest SATA II port feature, where one single eSATA cable connects to four 3Gpps SATA II hard drives. Designed with easy installation in mind, the trayless TR4M-B allows instant installation by simply inserting the hard drives after opening the protective ventilating cover. It supports JBOD and Spanning modes for instant storage expansion. It also supports RAID 0, 1 0+1, 5, 5+spare via included software utility, for high performance and hard drive redundancy. The package includes a 2-port eSATA PCIe card at no additional cost, which allows the connection between two TR4M units (up to 8 hard drives) using only two cables. PCI/PCI-X options are also available.
