The Promise 750GB SATA Drive Module is a hot-pluggable 3Gb/s 7200-rpm SATA hard drive in a special drive carrier module designed for hot-swappable upgrade or replacement. Advanced active/active MUX circuitry allows the single ported SATA drive to be controlled by both RAID controllers simultaneously offering transparent failover.

Serial ATA hard drives

Serial ATA hard drives combine low cost with excellent performance. They feature a point-to-point interconnect to each drive, so each drive is electrically isolated from the others and multiple drives don't compete for bandwidth. The drives come with 16MB of disk cache, operate at 7,200 revolutions per minute (rpm), and use a protocol that enables fast data transfer to and from the hard drive--3 gigabits of data per second.

Tiered storage in a single RAID box

The Promise VTrak E-Class drive modules can be mixed inside a single RAID subsystem or in the expansion chassis allowing for flexible tiered storage configurations. 7200-rpm SATA drives deliver high capacity and excellent sequential performance for audio and video data.

Promise serial ATA drive module compatibility

These SATA drive modules are qualified for use with Promise VTrak E-Class RAID subsystems and VTrak expansion chassis only.
