eSATA speed question

Does anyone have any idea on the transfer speeds of eSATA devices?

I am trying to find out if it is faster or slower than transferring files to a NAS over 100mb network connection (unmanaged).

I know you can get up to 3Gbps with eSATA but what are the transfer speeds in real terms? Is it faster than a 100mb network connection?

Almost certainly. 100Mb/s is only 12.5MB/s and most modern hard drives have real world transfer speeds which are several times greater than that.

eSATA will be significantly quicker than a NAS.

The 3Gbps figure is simply what the interface is capable of, the drive will be the bottleneck - expect to see about 55-60Mb/s average depending on the drive.

From what I've seen most 100Mbps NAS solutions will give you at most 10Mb/s.

Thanks for the replies - this is exactly what I am looking for.

Any recommendations on a proven and decent external eSATA chassis?

I bought one of these from OCUK

Seagate

I use an Akasa eSATA caddy - cheap, simple and effective.
