RAID

(Redundant Array of Independent / Inexpensive Disks)

A disk array in which part of the storage capacity is used to store redundant information about

user data stored on the remainder of the storage capacity. The redundant information enables

regeneration of user data in the event that one of the array member disks or the access path to

it fails. See Parity. Different RAID level offer different data throughput speeds and fault

tolerance (data redundancy). RAID 0 does not feature redundant information but is nonetheless

considered a special type of RAID.

Serial ATA

(Serial Advanced Technology Attachment)

Serial ATA (often abbreviated as SATA or S-ATA) is an advance on the commonly used

Parallel ATA interface for data storage devices. Serial ATA allows data transfer up to 1.5 Gbps.

It has an additional advantage parallel ATA in that cables are thinner, so airflow within computer

cases is less impeded, and can extend to one meter in length (against only 40 cm for parallel

ATA).
