What is the difference between DMA and SATA hard disk drives?
DMA:Direct Memory Access. A technique for transferring data from main memory to a device without passing it through the CPU. Computers that have DMA channels can transfer data to and from devices much more quickly than computers without a DMA channel. This is useful for making quick backups and for real-time applications. Some expansion boards, such as CD-ROM cards, are capable of accessing the computer
The difference between sata and IDe is that of Cable Connector that connect Hard disk to the motherboard, Sata Hard disk is a new technology and IDE is old, Sata is relatively fater to as of IDE, IDE cable differes from SATA cable, Toshiba has recently introduce its 5400 rpm Sata hard disk, the fastest sata hard disk in my knowledge is 7200 rpm by Seagette.
ATA = Advanced Technology Attachment and has speeds of up to 133 Mbps. Has a 40 pin connector. SATA = Serial ATA. Smaller connections and higher data speeds. See the attached link for a webpage with more info. The SATA host adapter is integrated into almost all modern computers. The difference is sata is 7 pin connectoe and ata is 40-44 pin
It depends. If it is a laptop hard disk, and you know the interface (IDE or SATA, there is a difference), you would purchase a 2.5" IDE/SATA Hard Disk Enclosure. If it is a desktop hard disk, and you know the interface (IDE or SATA, there is a difference), you would purchase a 3.5" IDE/SATA Hard Disk enclosure. Hopefully this helps.
this is strongly dependent on the type of "drive you are trying to connect" a ide hard disk "drive" as well as a floppy "drive" will use a ide ribbon cable connector a sata hard disk "drive" and newer cd/dvd, and ssd "drives" will use a sata connection (either rated at 3.0 gbps, 6.0 gbps or otherwise) you can also find other types of drives that are more along the range of enterprise grade server…
This is a data ribbon cable is used for computer drives, like hard disk drives, Optical disk drives, and floppy disk drives. They are also referred to as PATA cables. They connect to parallel ports consisting of 20 pins in one row, and 19 in the second, for a total of 39 pins. IDE cables are now considered old, having been largely replaced by SATA cables, which connect to newer drives which run at more…
