A little benchmarking

I installed my new desktop PC (Gigabyte GA-MA78GM-S2H motherboard, AMD Athlon X2 4850e processor, Kingmax 2GB DDR2 800 MHz) and since the motherboard has an eSATA connector I was able to use my WD My Book Home external drive via it's eSATA connection. I was playing a bit and did some benchmarking and tested actual file copying speed with some of my HDD's. I tested my:

1. Western Digital My Book Essential 250GB external HDD (USB2)
2. Western Digital My Book Home 1T external HDD (USB2 and eSATA)
3. Seagate 500GB 32MB SATA internal HDD
4. Samsung SP2504C 250GB 8MB SATA internal HDD.

First I run two hard disk drive benchmarking tools: the aged ATTO Disk Benchmark and HD Tune. Then I copied a 640MB file with Windows Explorer (native) and with TeraCopy free version (2.0 beta 4) and measured the time it took to copy. Then I did the same with 4 files altogether measuring 5,57GB. I gave copy speed in MB/s, actual time is in brackets. Here are the results:

Western Digital My Book Essential 250GB (USB2) [free space: 3%]

Copy test:

Western Digital My Book Home 1T (USB2) [free space: 76%]

Copy test:

Western Digital My Book Home 1T (eSATA) [free space: 76%]

Copy test:

Seagate 500GB (internal SATA) [free space: 95%]

Copy test:

Samsung 250GB (internal SATA) [free space: 6%]

Copy test:

Summary, conclusion?

It is very hard to draw any conclusion because there are so many factors affecting data transfer rate and because of the inaccuracy in measurement.

It seems that:

• TeraCopy increases copy speed, especially when copying larger files; on my internal Seagate HDD it was 1.5-1.7x faster
• WD My Book Home eSATA interface is approximately twice as fast as it's USB2 interface.
