Transferring files to another folder. Speed issue.

[Go To Sleep]

I run a 500GB WD Velociraptor as my C drive and I have a standard 7200rpm 500GB HDD as my storage (D drive). I'm only getting about 15mb/s right now transferring files/folders to another folder or transferring from C drive to D. Why is the WD HDD so slow? Am I missing something?

that should be right. this is a spin disk, not an ssd. Also, you transfer files from A to B location with spin slower than A.

There's various reasons, the more files, the slower the transfer as each has to be initiated and completed, so if you had a few large ISO's or ZIP files, that would go faster. Many files and folders will slow down.

There's chipset limitations, hard drive limitations, OS limitations, other hardware limitations that can slow you down. Though 15MB/s seems kinda slow depending on the file(s) being transferred. Mine usually jumps around but averages in the 80MB/s-range between drives on the same system or on my home network. Though I prefer to do large single-file transfers as they are much faster in my experience.

What types of files are you transferring? If it is a bunch of tiny files it will be a lot slower than transferring large files.

Also, what is the model of the second drive?

Right HDTune on both drives and see what results you get in the benchmark. Doing an error scan probably wouldn't be a bad idea either.

that should be right. this is a spin disk, not an ssd.

No, it isn't even close to being right. A standard mechanical hard drive should be able to get close to 100MB/s transferring data, depending on the data.

+1, QFT and all that....

It depends on the type of files being transferred, as well as size. Also, despite the faster velociraptor, it transfer speed cannot be fully utilized, since it is limited by the slower drive's ability to write the data. Finally, write is always slower than read.

However, all that said, that sustained transfer speed is a little bit low I think, without further info.

Files are about 1.50GB. Speeds are about 15mb/s and take forever for that file size.

Hey, @Go To Sleep!

This seems rather unfortunate. I'd suggest you to run tests on the VelociRaptor as well and check up on the health and S.M.A.R.T. status. You can also use WD's Data LifeGuard Diagnostic tool to do that. Just make sure you run the QUICK and EXTENDED test from the utility. Here's a link to it: http://products.wdc.com/support/kb.ashx?id=uySQNl
I'd also recommend backing up any data from the drive somewhere else, just in case. And it might also be a good idea to check the warranty of the WD VelociRaptor here: http://products.wdc.com/support/kb.ashx?id=OpQHRg

Keep us posted with the S.M.A.R.T. results.

Are they SATA or IDE? SATA 2 maybe? Something is using the SATA buss ?

Could be a bad SATA cable. I erased hundreds of 80 GB drives and the normal erase time was about 2 hours. Every now and then, I'd get a computer that takes 4+ hours to erase without errors. I swapped the SATA cable and everytime, the second erase would drop down to the usual 2 hours. I'm not entirely sure why it happens but SATA uses error-correction so my guess is that a lot of packets end up getting dumped but some still get through. It really trashes performance but other than that, it can go unnoticed.

I even recall one drive where performance fell to less than 1 MB/s. Computer still worked but it took like an hour of the computer to boot to Windows. Replacing the cable there fixed it too.
