TrayFree™ Trayless Technology for RTX™ Enclosures
WiebeTech's TrayFree bays make adding drives a breeze. It really is as easy as opening the door, sliding the drive in, and closing the door. No screws, no trays, it just works.

Sorta Like Floppy Disks, but Better
JBOD (Just a Bunch of Disks) RTX enclosures, such as parts ending in SJ, NJ, and SV units, bring back an old familiarity to comping - the mentality we had with floppy disks. The great thing about floppies was certainly not the polite 1.4MB of storage space... but do you remember when you could keep a pile of floppy disks hanging around, and pop one in whenever you need it? It's becoming more and more common to have piles of hard drives with data you need to access quickly. The RTX line allows you to think about hard drives in an old way: Pop them in and access the contents without fussing with the enclosure or even a tray. With the RTX TrayFree™ technology, loading a SATA drive takes only a few seconds.
