Data transfer via SATA or eSATA
A little secret, when you RUB the small letter e out. eSATA stands for external SATA. While the Serial-ATA is designed for the transmission of data in the PC-Internal, can be connected with the eSATA cable external hard disks. The main difference between eSATA and SATA, therefore, is:
- The eSATA technology is externally applied and the SATA technology internally.
- Therefore, the length of the cable is a significant difference.
- The SATA cable is up to a Meter long, and the eSATA cable is up to two meters. Therefore, the transfer voltage in the case of the eSATA cable was increased accordingly.
- In addition, you must have the eSATA technology, of course, the cable and the plug and the socket via an electro-magnetic shielding. In the case of SATA, the need to, because the housing already does all the protection.
- In addition, the eSATA-Connectors are equipped with small springs, so that the cable is not pulled out accidentally constantly out. This risk is, of course, in the case of the internally applied in SATA technology.
- Because of these peculiarities is, of course, clear that the cable can not be exchanged for the data transfer easily with each other.
