And what else examining the bits along the way. You also have issues such as "WHO INSTALLED THIS OS?" since many won't fetch current or even the correct drivers.
To do speed tests we may have to examine dark details of the cache size of the drive and test the transfer rate inside that size (transfer rate will be limited when we actually read from the drive.) You also are writing to a drive and even a simple item such as NT/2000/XP timestamping files and making event logs will thwart the tests.
Sorry, I wish there was a simple test for you but I must defer to many fine speed test web pages out there. Compare with those.
I have a concern about the speed of a new system I recently bought. It is an Intel Core 2 Duo E6600 processor on an MSI Neo-F P965 motherboard with 2 GB or RAM. The hard drive is a Seagate 320 GB SATA3, (model ST3320620AS). This drive is supposed to have a max throughput of 3 Gbits per second.
I suspected the HD data transfer rate was not as fast as I expected it should be, and today after buying an additional drive, I did some tests. I had a ton of media files on the C: drive, and after installing and formatting the new D: drive (which incidentally, is the same model as the original C: drive) I decided to time the transfer rate by moving the media files from the C: drive to the new D: drive.
It took 124 minutes to copy 243.5 GB of data from the C: drive to the D: drive. By my calculations, that works out to about 32.73 MBytes per second, or slightly less than 300 Mbits per second - I am guestimating this by allowing 9 bits per byte to cover overhead. Still, 300 Mbits is a far cry from 3 Gbits!
When installing the new drive, I noticed there was a 'default' jumper on the drive, that limited the transfer rate to 1.5 Gbits per second. (ref: http://www.seagate.com/support/disc/sata/st3320620as.html ). I also noticed that the original drive also still had this jumper installed. I left both jumpers in place. I spoke with the dealer who built the system about this, and he said they never remove the jumper - that the actual transfer rate is controlled by the motherboard and that my motherboard was very new and would override this jumper and do a 3 Gbit transfer, not 1.5 as the jumper was set.
Now, I have a hard time believing this, especially in light of my recent data transfer test. I wrote to Seagate to inquire about this, but still have not had a reply - it is Christmas time after all, and I don't expect them to get back to me before next year. However, even if the jumper was limiting the transfer rate, and even if removing it doubled the rate to 600 Mbits, that is still a far cry from 3 Gbits.
So, my question is: am I being unrealistic in expecting a faster data transfer rate with this system?
