Shouldn't a NAS hard drive be better than this?

mine gets 24MBps when transferring large files(>1GB) in my PC from another hard drive which consistently sends data @ >100MBps to my other drives in my PC.
Why is it so slow? It doesn't matter if it is connected via SATAIII or ESATA. I've tried it in another PC with the same result.
 
Can you give some more details? What is the exact drive model, how full are the sending/receiving drives, what is the rest of your set-up like?

Something sounds wrong but without more information that's about all one can say.
 
Is your SATA port on a different controller than the other drives?

Please run the HDTune benchmarks mentioned here (rather than a file copy, which isn't a terribly reliable benchmark anyway) and post screenshots.

The drive should be capable of a lot better than 36MB/sec.

Edit: sorry, you said you tried it on two different PCs. I'd still benchmark it for comprehensiveness' sake, but if the benchmarks are as bad as the performance you're seeing, I'd be looking into an RMA of the drive.

Edit 2: Also, look at the HD activity light on your computer - during a disk-to-disk file copy, it should be pretty much solid. If there are gaps and blinks, it may mean the computer is waiting on something... else.

Edit 3: Google says no, but just to be sure - this is a NAS drive and not an Archive drive? It doesn't use SMR?

This was a concern I considered also, but newegg/amazon say that part number is a NAS drive w/o SMR.

I 2nd the HDTune benchmark. Post those results, and if they're equally bad, I think it needs to be RMA'd. A 4TB drive should have no trouble transferring ~100 MB/s in sequential writes if it is mostly empty.
