This information is transferred via a cable system, or through a wireless connection to a hard disk controller, which in most systems is built into the motherboard, or in some systems installed as an add-in card. The information that comes from your hard drive through its controller is then made available to the components of your computer. The effectiveness of your hard drive (its performance) depends on how much of its capacity remains unused Men's Nike Air Max 270 Flyknit Oreo Black Australia , how well organised the data is (known as fragmentation) and its data transfer rate, which in turn is dependent on its connection type and the drive's spin rate.

ATA (Basic). Supports up to two hard drives and features a 16-bit interface, handling transfer speeds up to 8.3 MB per second.


ATA-2 or EIDE (Enhanced IDE). Supports transfer speeds up to 13.3 MB per second.


ATA-3. A minor upgrade to ATA-2 and offers transfer speeds up to 16.6 MB per second.


Ultra-ATA (Ultra-DMA, ATA-33 or DMA-33). Dramatic speed improvements, with transfer rates up to 33 MB per second.


ATA-66. A version of ATA that doubles transfer rates up to 66 MB per second.


ATA-100. An upgrade to the ATA standard supporting transfer rates up to 100 MB per second.


ATA-133. Found mostly in AMD-based systems (not supported by Intel), with transfer rates up to 133 MB per second.
