CEBIT - Raidon offers small RAID module for the masses

Taiwan's Raidon has developed a small RAID module that fits into a 3.5-inch drive bay

Taiwan's Raidon Technology has developed a small RAID (redundant array of independent, or inexpensive, disks) module that fits neatly into a 3.5-inch drive bay.

The SR2760 has room for two 2.5-inch SATA drives and offers the option of using either RAID 0 to increase capacity and boost performance or RAID 1 to ensure users won't lose valuable data in the event one disk crashes. The module can support up to 2T bytes of disk space and transfers data at speeds up to 300M bytes per second. It was announced during the Cebit trade show in Hanover, Germany.

For years, RAID has been largely confined to corporate data centers and server rooms. The technology, which divides up data between different drives, can either provide redundancy in case of a hardware failure or speed up disk access times.

RAID 0 offers no protection in case one disk crashes, but can speed up data speeds and maximizes use of the combined capacity of the two drives. In this mode, the SR2760 splits data across both drives in the disk array, which are treated as a single disk by the computer.

In RAID 1 mode, the SR2760 offers redundancy, mirroring data across the two disks, so that data is preserved in case one disk fails. The catch is that because data must be mirrored, or written twice, the capacity of the array is equal to the capacity of one disk.

The SR2760 works with Windows, Mac OS X and Linux, and allows users to swap out drives while their computer is running. The module has two disk trays that can be ejected, allowing users to add or replace disks.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
