Difference Between EIDE and SATA

sata-diskEIDE vs SATA

Enhanced Integrated Drive Electronics, or EIDE, is a computer data storage device which has adequate space to store large quantities of computer data and files. It can store about 500 Gigabytes of data. It has an interface feature that’s being used for information communication between system details. Its rate of speed is 133 megabytes per second, using a 28 bit Logical Block Addressing (LBA). The EIDE has 40 pin attachments.

EIDE also permits using a combination of four devices – such as hard disks and CD ROMs – for connection, using its two large interface cables. The cables are designed to let two devices connect to each. The motherboard, which in-houses the EIDE system, grants faster entry to the hard drive, backing the Direct Memory Access (DMA) with no slots needed. DMA is a function rendered by the computer bus, permitting data to be sent directly from an affixed device to the memory of the motherboard. Therefore, the entire computer’s operation is faster, because the microprocessor is discharged from conveying data.

The EIDE disk, however, is not always compatible to an old Personal Computer (PC). The CD-ROM is also slower compared to the hard disk, and will be bustling longer if placed in a similar cable with the hard disk. It will impede the disk access when an inquiry is initiated, so it’s better to have a separate cable for the CD-ROM. Nevertheless, EIDE is excellent, and compatible with most computers nowadays.

On the other hand, Serial Advanced Technology Attachment, or SATA, has a 40 to 750 gigabytes storage capacity, and can run at a rate of 150 megabytes per second when transferring data. Its dimension is three feet, or one meter long, with very slim cables that are adaptable for installations. It has seven pin attachments, and needs only minimal power to operate. The drives can simply be detached and set up while the computer is still operating. The major benefit of SATA is that it takes away the ‘boss and subordinate’ working relationship.

However, the advantage of EIDE over SATA is the price, as SATA is a bit more expensive than EIDE.

Summary:

1. EIDE has a 133 megabytes per second speed rate, while SATA has up to a 150 megabytes per second speed rate.

2. SATA has about 40 to 750 gigabytes of storage capacity, while EIDE has a maximum of 500 gigabytes storage capacity.

3. EIDE uses Logical Block Addressing (LBA), that supplies adequate information for exclusive sector determination, while SATA does not use LBA.

4. EIDE has 40 pin attachments, while SATA has 7 pin attachments.

5. SATA has slimmer cables compared to EIDE’s more cumbersome cables.

6. SATA does not follow the ‘boss and subordinate’ rule when connecting two equipments.

7. SATA is more expensive than EIDE.

8. SATA drives can be detached and reattached while the computer is operating. EIDE, on the other hand, is not capable of such activity.
