An Array of Tiny Hard Disk Drives
 

Imagine a six-drive array of 80GB hard drives that fits entirely in a single 5.25-inch, 1/2 height drive bay. This is made possible by using 2.5-inch drives primarily targeted for laptop systems. We originally saw this JMR SATAStor at the Intel Developer Forum a year ago.

Of course, you can't just drop a six-drive array of SATA drives into your typical desktop system and expect it to work. So 3Ware shipped us an Escalade 9500S-12. This PCI-based RAID controller supports up to twelve SATA drives in a variety of RAID configurations (and in a JBOD—"just a bunch of drives" setup, if that's what you want). The controller offers flexible support for RAID 0, 1, 10, 5 and 50, giving you a choice for the right mix of performance and data integrity.
