The toshiba mk6459gsx gets a Passmark drivemark of 471, making it a mid range 2.5″ drive, so not too shabby, given the capacity.
The only bad thing to say about this drive is that it comes in a plastic case. Freecoms used to come in a metal case, so I guess that some cost cutting has taken place to stay this competitive, but I can’t really complain especially give that the bare hard drive itself costs more than the current asking price… but you will need a case if you want to carry it about a lot.
Also worth noting that the drive comes formatted as FAT32. I reformatted to NTFS (so that I can copy large files onto it, such as DVD images), and that took about 8-10 hours to complete! Bit of a bind, but not really a massive headache (I just left it to go overnight).
All in all, very pleased; its a perfect backup drive for what I wanted (I back up my digital photographs, DVD images, and documents folder to it), and very cheap for the capacity. The drive is pleasing to the eye and very quiet too. It also runs off the USB for power so no issues with finding plugs. I also bought the suggested protective case for when I take the hard drive out and about. It fits snuggly and seems well protected.
I have only used it to back up data, so have not accessed it that much. Time will tell I suppose how good this drive really is, but so far I have no complaints.
