hard disks, optical disks basic explanation of the connection.

In addition, UATA, PATA, E-IDE, parallel IDE, Parallel ATA, etc. may also be expressed.

I may be almost the same unless the expert. Standards disuse.

The relationship between data rate ATA33, ATA66, ATA100, ATA133, there is a standard.

Is different in the shape of the attachment 2.5inch and 3.5inch.

SATA can be received while sending data.

There are standards that SATA1.0 and SATA2.0 and SATA3.0.

eSATA is a External SATA to use as USB, and can transfer data faster than USB.It is for the external optical disk and the external hard disk.

SCSI connection is not there a long time. The SCSI card is expensive, the data transfer speed is fast, suitable for connecting an optical disc and hard disc.

However, the advent of eSATA and USB2.0, not often used now.

SAS Standards can be received while sending data.

There are standards that SAS1.0 and SAS2.0 and SAS3.0.

SAS standard hard drives are expensive compared to standard SATA. However, the data server is used. Because, for fast data transfer and low failure rate.

Allows you to connect your SAS hard disk failure rate is low and only motherboard SATA interface.
