Get HGST 8TB Ultrastar He8 Hard Drive at OWC.
Also utilized in the 32TB OWC Thunderbay 4 RAID-5 edition.

RAID 0 is the highest performance RAID mode, striping (simultaneously initiating) reads and writes across multiple drives.

RAID-0 striping requires two or more drives. Ideally, performance should scale linearly: N drives should be N times as fast as a single drive.

Performance testing by DiskTester, part of diglloydTools.

Drives hosted in the OWC Thunderbay 4 with software RAID by SoftRAID 5.1b21.

RAID-0 sustained transfer speed

DiskTester run-sequential used to test peak speed of empty volume, freshly erased. Throughput figures are real-world figures through the OS X file system.

It doesn’t get any better than this: perfect straight-line linear RAID-0 scalability: five drives are five times as fast as a single drive.
