eSATA to eSATA transfer speed slow

[mlah384]

I have 2 external hard drives that I am trying to transfer all of the info off of one onto the other.

They are a Segate 750GB SATA HD (ST3750330AS) in an Antec MX-1 USB2.0 & eSATA External Enclosure and an Hitachi Deskstar 2TB HD (HD32000 IDK/7k) in a Rosewill RX358 USB2.0 & eSATA External Enclosure. They are both connected to the computer via 2 eSATA ports on the motherboard. I am transfering 650gigs off of the Segate 750GB HD to the Hitachi 2TB HD. The transfer speed according to Vista is varying between 15mb/sec to 28mb/sec. Isnt that WAY too slow for eSATA? I thought it would be 300mb/sec? Am I missing something?

Thanks

look in device manager under disk drives and go to the drive in question and right click it then properties. then go to the policies tab and enable advanced performance. i just setup a MX-1 myself and run into the same exact thing

You will *never* (Well, unless there is some vast improvement on platter density), see a mechanical drive push data anywhere near 300MB/sec, unless you got some serious RAID hardware. That is the interface speed, the actual HD speed, depending on the data, and where it is located, yes, it can go down that low.
The other issue may be that while the Rosewill might have a eSATA port, it still might transfer at USB 2 speeds. There are some really cheap controllers that do this.

that's funny, my seagate 1tb does 100-105 mb\sec pretty consistantly inside my MX-1 using esata port.

Thanks for answering! It ended up getting to about 50-68mb/sec. and sustaining that speed but it took about an hour before it got to that point. Took about 4ish hours to transfer 700gb to the 2Tb Drive. I wish I could get faster than that... A LOT faster than that!

ur file size also matters and day dreaming dude.
we all do that...
