Toshiba vs. Seagate

[danielcummins]

In our company, we use Lenovo laptops but with a mixture of hard drives. Lately, I've found that the hard drive performance varies between laptops but we cannot figure out why. The laptops with the Seagate hard drive perform better than the Toshiba hard drives. I have compared the hard drives in every way that I can think and all of the specs are identical except for amperage (which should not impact performance). Is there really such a big difference based solely on the brand or is there some spec that I am overlooking that is causing such a performance variance? Here are the specs that I have compared that are the same between drives:

Seagate Momentus 7200.4 9HV144-071
RoHS
500 GB
7200 RPM
3.0 Gb/sec
+5V 0.451A
LBA: 976,773,168
CHS: 16,383 / 16 / 63

Toshiba MK5061GSY
RoHS
500 GB
7200 RPM
3.0Gb/sec
+5V 1.1A
LBA: 976,773,168
CHS: 16,383 / 16 / 63

Thank you for your help.

Seagate's business is hard drives, Toshiba's is not. Also, the amp difference could be a factor - the Toshiba requires twice the power to deliver the same performance - in laptops, that power draw may be unavailable depending on what other 5v requirements have to be met.

the seagate has ncq. the Toshiba does not.
Thats the only real difference I could find on the two.
