In this digital age, data is as important as breathing. Creating data, keeping data, and even transferring of data should be done in the safest and fastest way possible. And when it comes to transferring files, media storage devices have different modes of doing that. One of the fastest, if not the fastest, is the eSATA or external serial advanced technology attachment.
The eSATA is one of the latest revisions of Serial ATA. This is an interface for computer bus used to connect host bus adapters to any mass storage devices like optical drives and hard disk drives. The development of SATA is also a revision from an older interface called PATA or parallel ATA. The main advantages of the SATA are smaller cable, lower cost, faster data transfer, and more efficient data activities.
eSATA is another development from this development. “External” is the keyword that explains the main difference of eSATA to the old SATA. Since external, this newer interface is used for external devices like external hard disks and video camera recorders.
Main Advantages of eSATA
The eSATA is comparable to USB and FireWire 400. The former was introduced when the latter were already dominating the market. But eSATA has something that could help it withstand the competition. Here are some of eSATA’s advantages:
- Fast transferring of data. Compared to FireWire 400 and USB, eSATA is way too fast, triple as fast as these two. USB was created not actually for data transfer but for connecting printers, keyboards, and mice. Meanwhile, eSATA was primarily created for data transfer. It is therefore expected to be good at what it is supposed to do.
- Longer. Unlike USB and FireWire 400, eSATA can use a cable as long as 2 meters even outside the computer.
- More durable. The cable of eSATA is covered with durable materials that can better withstand wear and tear.
- Easy to use. It may not be a plug-and-play like USB but it is hot-plug. Connecting and disconnecting eSATA will not require you to shut down the system.
- No data translation needed. Using eSATA to transfer data is mostly without lag because the computer understands the data from this device without translation.
These advantages are great reasons to always consider using eSATA. There maybe other alternatives but the strong points of this bus can make it always worth considering.
Main Drawback of eSATA
Despite the good things, eSATA still has some bad things and these are:
- Power cables. You can’t use eSATA if it’s not plugged to its own power source. Unlike other buses that draw power from the cable, eSATA is in need of power directly from the source. But this will not be long because the SATA International Organization is already working on a newer version that will erase this major eSATA drawback.
- Enclosure. This bus will need its external enclosure that should be supporting eSATA.
- Less convenient. Compared with other alternatives, eSATA is not that convenient to use for on-the-go people. The cables are longer, the size is bigger, and it needs a power source.
There may be some eSATA drawbacks but these are not enough to scare away the many advantages of using the bus. USB and FireWire 400 may be available, but when you need the fastest and most reliable way to transfer data, there is no better bus for the job but the eSATA.
