Which hdd is faster

[rarenick]

Assuming both hdds runs on USB 3.0 interface.

1. 7200rpm SATA II 3.0Gb/s

2. 5400rpm SATA III 6.0Gb/s

Pls note again that both hdds are connecting to pc via USB 3.0 interface.

A 5400rpm HDD from 2015 will be faster than a 7200rpm HDD from 2010

1. 7200rpm is 7 yrs old drive
2. 5400rpm is like 2 or 3 yrs old drive

Any data to backup your claim?

some link below for you to read up.
So it seems to be very minimal diff between sata 2 and sata 3 but a 7200rpm drive will have a higher impact over a 5400rpm drive
So in you case, a 7200rpm would perform better

which is theoretically faster

My 7200RPM HDD is also 7-years-old. Hahaha... And it is a Hitachi HDD somemore.

Yup mine is Hitachi. Now trying to see which one to use as my primary backup ext hdd. Need to buy a casing first to test the speed.

Not necessary actually. The transfer rate on the newer and denser platter will be better, but the 7200rpm drive will always have an advantage in terms of response time.

Anyway, it does not matter whether is SATA 2 or 3 since most if not all consumer class mechanical drive can barely saturate SATA 2.

If for backup, I'll choose the younger HDD by default.
