HDD #1 - #4 Western Digital WD3202ABYS (WD RE3):
  • 320GB capacity
  • 16MB data buffer
  • 7200RPM
  • Serial ATA 3.0GB/s interface

High performance enterprise SATA drive designed specifically for business-critical applications.

Keep in mind, that a computer scientist calculates as follows:

  • 1KB = 1024 bytes
  • 1MB = 1024 x 1024 bytes
  • 1GB = 1024 x 1024 x 1024 bytes

Whereas an HDD manufacturer calculates the capacity of a harddisk as follows:

  • 1KB = 1000 bytes
  • 1MB = 1000 x 1000 bytes
  • 1GB = 1000 x 1000 x 1000 bytes
Therefore software for the maintenance of HDDs often displays a lower capacity than specified by the HDD manufacturer.
HDD #5 - #6 Western Digital WD5002ABYS (WD RE3):
  • 500GB capacity
  • 16MB data buffer
  • 7200RPM
