2.5" 7200rpm vs 5400rpm

i want to purchase an external 2.5" drive, where speed plays a major factor to me.
Considering these two drives:
Seagate STBE320200 - 320GB, 7200rpm, USB3
Seagate Expansion Portable Expansion STBX1000200 - 1TB, 5400rpm, USB3

They are about the same price. my question is how much faster is the 7200rpm? is it really worth the sacrifice in capacity? also when working in USB2 mode? is the a faster drive then both?

  1. There isn't a huge difference between 5400 RPM and 7200 RPM. I would much rather go for the 1TB drive over a slightly faster drive.
  2. i process a lot of images, so speed is important. can you you say how much in percentage the 7200rpm is faster? i saw somewhere that Seagate claims it's 40% faster but somehow it doesn't make sense.

    I have both a 5400 RPM and a 7200 RPM HDD in my system. The 7200 RPM is 1TB and the 5400 is older and 500 GB. The difference is really minimal, tbh look at some reviews of read and write speeds, and you won't find a huge difference.

    Plus, more space> speed, especially when you are comparing 320GB and 1TB. simply not worth it to get a 320GB, I guess you could get a SSD..
  4. Ok, so i just as well ask, which one would you prefer?

    Seagate Expansion Portable Drive 1000GB Expansion 1TB STBX1000200
    Transcend 1000GB TS1TSJ25M3

    both are more or less the same price.

  5. I'd go for the first one, because I've never heard of the second brand Transcend.
  6. If you're going to be using them in a usb2 port then get a 5400 rpm drive. It will run a bit cooler and so might last you a bit longer (heat kills)

    Any Harddrive is faster than a USB2 port so rpms is irrelavent.
