Hello! I've just bought a Seagate HDD, model ST1000DM003 (-1CH162).

Immediately after installing the first game I noticed that the Loading time was the same or sometimes more than in my previous HDD, Seagate ST3320613AS which is much more older and has lower specs. The first thing I did was to copy/paste a 10GB folder from one location to another on the hard disk. While it first began at 181MB/s which is OK but not perfect for the hard disk's capabilities, after 2 seconds it suddenly dropped to 100MB/s, then 60, and then it decreased to 20-25MB/s max, throughout the cope/paste process. I tried with all kind of files, all formats and sizes, different locations and I always end up having the same speeds.

Then I searched for a HDD SpeedTest program and I found HDTune. I run the Benchmark and I got this result:

I run it again:

I really dont know what is really happening, but it looks quite unstable to me.
I also did the File Benchmark test and I got these results:

in the test above, the transfer speeds seem to be the optimal ones, but that's just not happening in the actual tranfers. My OS is Windows 7 Professional SP1 64-bit, Motherboard model GIGABYTE GA-MA770-UD3 and I use SATA2 instead of the optimal SATA3 (but that is not the problem as SATA2 can handle up to 300MB/s).

If anyone knows or suspects anything please help, as I dont know if it's the Hard Drive that is faulty or it's me who does something wrong. If any more info from me is required, just say the word. :)

Does anyone else have the same Hard Drive? What Benchmark results do you get?

Yep, Seagate disks are not good, it looks good on paper but in real world scenario it is not good, on brand new Barracuda 2tb 256mb cache, speed drops to 20Mbs while copying 6gb file. Seagate disks have long access times.
Never will I buy Seagate again, WD is better.

I tried that and I get the exact same benchmark results.

I also tried to unistall the Hard Drive from the Device Manager and let it reinstall itself after restart but it makes no difference.
