This is a general listing of Personal Computer Hard Disk Drive [HDD]
manufacturers.
Solid State Disk Drives which are completely Flash are listed on the SSD page.
Hybrid Hard Disk Drives which rely on a large amount of Flash are listed on the HHD page.
The different types of disk drive bus interface types are
listed below. Keep in mind that the IDE drives, Parallel ATA [PATA], Bus
is being replaced by the Serial ATA: [SATA] bus.
Electrical Interfaces:
Internal Interface types; ATA [IDE], Ultra ATA, SATA [Desk-top], SATA, SCSI, Ultra SCSI, Serial SCSI [Enterprise]
External Interface types; eSATA [Desktop], SCSI, Serial
SCSI [SAS] [Enterprise], Fibre Channel [Enterprise],
Firewire, or USB
The four common Hard Disk Drive applications are Desk Top Computers,
enterprise servers, workstations, and notebook computers.
Laptop Computers are normally the slowest and smallest
Desk Top Computers are middle of the range speed drives
Workstations use high-end disk drives
Enterprise servers use the fastest and most expensive hard drives
The four common physical drive sizes are 0.85 inch, 1.8 inch, 2.5 inch,
and 3.5 inch [example size].
0.85 inch drives are 0.13" x 0.94" x 1.26"
1.8 inch drives are 0.315" x 2.12" x 3.09"
2.5 inch drives are 0.370" x 2.75" x 3.94"
3.5 inch drives are 1.000" x 4.00" x 5.74"
The three common disk rotation speeds are 5400 rpm, 7200 rpm, and 10000
rpms
5400 rpm Hard Disk Drives found in note book computers
7200 rpm Hard Drives found in desk top computers
10000 rpm Drives found in work stations, enterprise systems

SATA 300MBps, EIDE Drive, Enterprise, Desktop, Mobile, External Hard Disk
Drives}
-----------------
Personal Computer Hard Drives use a number of different types of
electrical interface buses to interconnect the physical harddrive to
the PC's mother board. Mini-IDE [MIDE] is a small form factor Solid State Drive. |
