|Okay, recently purchased new SEAGATE SATA 3.0Gb/s which translates to |
3 Gigabits/sec =>
3,000,000,000bits/sec / 8 = > 375,000,000
375,000,000 / 1024^2 = 357 Mbytes / sec.
Here are the tests I ran:
Athlon Phenom 3 core
- Large data transfer (64G) between two partitions in Linux Ubuntu 11.04: 12-13M/sec (initial few seconds 50-60MB/s after that rate steadily dropped. Roughly same result in Windows 7.
- Between two same HDD, surprisinly the rate was higher 30-40MB/s
- Used GHOST to clone the whole partition with data with 64G, took about 40mins which translates to about 27MB/s.
This is far below the manufacturer's spec, now I know the ideal transfer rate can not be achieved in real life but neither do I expect it to be this low speed either.
Here I am taking inputs from user people who have done similar test and I am especially interested in inputs of how to make the test environment as close to the ideal speed as possible.
