Key Features
Spindle speed is the speed at which the drive's memory disc (or platter) spins. A higher spin rate improves both positioning and transfer performance for sequential operations. This means that the faster it spins, the faster data can be read off of the disk for single operations.
Designation dictates the type of machine the Hard drive is made for.

Technical Features
Internal Data Transfer Rate provides the best overall measurement of a drive's performance. The number represents how quickly data is read within the hard drive itself.
Internal Data Transfer Rate
688 Mbit/s
External Data Transfer Rate is used to measure how quickly a hard drive is able to move data to the system. This is highly dependent on the interface type used.
External Data Transfer Rate
320 MBps
Refers to the time a drive takes to locate a particular piece of data.
The interface is the type of connection (such as FireWire or USB) used by your hard drive. Home systems will mostly use an IDE interface. Professional systems can use higher quality interface, as SCSI.
