RAID (Redundant Array of Independent Disks) References
en.wikipedia.org/wiki/Redundant_array_of_independent_disks
- RAID 0 stripes data across multiple discs for better
performance
- RAID 1 mirrors the data for redundancy
- RAID 5 combines both with striping plus distributed parity information

PCI - Peripheral Component Interconnect / PCI Express (PCI-e)

PCI-SIG - PCI Express - PCI-X 2.0
- PCI Express bidirectional, and faster then
the older PCI and AGP interfaces
- guarantees each device dedicated bandwidth through
the system controller
- slots are defined by their bandwidth, or number of
data lanes - 1, 4, 8, 16 lanes
- one card can support 1 to 32 lanes at 250
MB/sec each, up to 8 GB/sec
- PCI Express x1 about twice as fast as PCI
- 4-lane slot can transfer data at up to 1 GBps
- PCI Express x8 is around the speed of the fastest AGP
up to 2 GBps - almost 2X 133MHz PCI-X slot at max
throughput just over 1 GBps
- previous PCI Extended, PCI-X

SATA -- Serial ATA / eSATA -- External SATA

- Designed to replace the older ATA and SCSI formats,
offering higher performance with ease of connection
- ATA drives low cost, high capacity
- Internal data rates reaching up to 75 MB/sec, USB
and 1394 interface rates are bottleneck
- Internal: SATA 1.5 Gb/sec (150 MB/sec) or SATA 3 Gb/sec
(300 MB/sec)
- External: eSATA with more robust cables and
connections (multiple insertion , shielded)
Electrical Static Discharge (ESD) , Electro Magnetic
Interference
