;Access Time | |||
: The time it takes to access data on the drive. | |||
;Cache | |||
: Technically called the Disk Buffer, it is the embedded memory in a hard drive acting as a buffer between the rest of the computer and the disk platters that are used for storage. It is used for read-aheads, write acceleration, and speed matching among other things. | |||
;Capacity | |||
: Capacity is the amount of data the hard drive can store. It is measured in gigabytes (GB) or terabytes (TB). | |||
;Form Factor | |||
: This refers to the physical size of the drive. | |||
;Interface | |||
: The interface is the type of connection the disk uses to connect to the motherboard. The most commonly used is Serial ATA (SATA). SATA is available in 1.5Gbit/s, 3Gbit/s, and 6Gbit/s transfer rates. 3Gbit drives can run on 6Gbit motherboards but not visa-versa. Integrated Drive Electronics (IDE) interface is now obsolete. | |||
;RPM | |||
: Revolutions Per Minute (RPM) is the speed at which the disk platters spin. 5400, 7200, and 10,000 RPMs are the standard speeds. | |||
;Seek Time | |||
: A measure of how long it takes the head assembly to travel to the track of the disk that contains data. | |||
