This is the ultimate RAID array! 24 Samsung Solid State Disks (they're like high speed flash memory as a hard drive) in RAID 0 running a total speed of 2 GB/sec... that's right, TWO GIGABYTES per second!

To give you an idea of how fast that is, here's what modern hard drives can do...
WD Caviar SE/Blue 55 MB/sec
Seagate Barracuda 7200.10 87 MB/sec
WD VelociRaptor 130 MB/sec
Samsung SSD 220 MB/sec (68 MB/sec short of the maximum speed of SATA 3Gbps)
24 Samsung SSD's in RAID 2010 MB/sec
