Barracuda XT, Barracuda, Barracuda Green, DiamondMax and other desktop SATA and IDE drives

When copying large files between my Barracuda drives (st31000528AS st2000dl003) even with nothing else running I get about 20-25MB/second.

Is that good or bad?

If bad, how can I get an improvement.

Running Windows 7 on  Gigabyte Technology Co., Ltd. GA-MA785GMT-UD2H with AMD Phenom(tm) II X2 545 Processor and 4GB Corsair DDR3 RAM.

Drives are on different channels, but one contains Windows system.

Update your chipset drivers and try a different sata leads or swap the ports around, make sure your sata leads aren't kinked.

Many small files are slower to copy than a few large files. Using the same two drives you mention and copying over a USB 3.0 connection, I get speeds in the range 70-80MB/sec  when copying large files. Using two ST2000DL003 connected to the motherboard via the Sata 6.0 Gb/sec ports, I get speeds in the range 80-130MB/sec depending on file sizes.

if your cables do not have clips, new cables have clips to ensure a solid connection.

I was going to say big files tend to slow down, also you have one 7200 drive with a 5900 drive, the 5900 is a slug, although I still think you are a driver short or the sata leads need re-porting, master should be on a lower number slot that the slave, i.e 7200 port 0, 5900 port 1.

I own the same disk as the OP (ST2000DL003) and copying MP3 files is fast and can achieve close to 45MB/s from a ST37500528AS

The benchmarks seem in line too, so I suspect the OPs small files can slow things down.

I cloned the 750 to the 2TB and it took very little time, the 2TB green has excellent sequential write performance which is ideal for video.

"...the 5900 is a slug"

I disagree. I'm using four of each type of drive (ST31000528AS and ST2000DL003) internally, externally, both as boot and data drives. I find the drives give comparable performance in all situations. Now that's not to say the 528AS won't be quicker under some conditions, but as a general perception, I doubt anyone could consistently tell the difference if they didn't know which drive was inside the box.

ST2000DL003 reviews I read showed it to be respectable, that is why I bought it, so I could install vast numbers of PC games

Never had a problem with it, works perfect as expected

If speed is that critical, get an SSD

Lovely to hear you say so mate, I'll not argue that one with you, if you are happy, that's all good.
