RAID (Redundant Array of Independent Disks)
: Technology
that allows two hard drives to be connected together, providing
a variety of benefits. The most common setup is RAID 0 which
offers increased hard disk performance since two hard drives are
working to process that same data. Most motherboards today
support RAID0 and RAID 1, eliminating the need for a separate
controller.
ROM (Read Only Memory)
: Drives with a “-ROM” suffix can only
read data from disks. These drives cannot burn CDs or DVDs.
RPM (Revolutions Per Minute)
: The speed at which a hard drive
rotates its magnetic platters. Traditional speeds include 5400RPM
and 7200RPM. Serial ATA offers speeds of 10,000RPM.
SATA/ 150 or Serial ATA (Serial Advanced Technology
Attachment)
: High-speed interface for connecting hard drives
to the motherboard. SATA replaces ATA by offering increased
data transfer speeds (up to 150 Mbps), and cables that are easier
to manage inside a system’s case. Today’s motherboards can
support 2 Serial ATA drives in a RAID configuration.
USB/ USB 2.0 (Universal Serial Bus)
: A technology that allows
all kinds of peripherals, from printers and scanners to mice and
sound cards, to connect to your system. USB 2.0 ports improve
data transfer rate over the original USB. USB devices can be
connected and diskonnected while the system is on.
