I spent two or three days researching external HDD's, and eventually, after some protracted head-scratching, I decided to go for this one.
Essentially (or so it seems), buying any make or model of external HDD can be somewhat of a lottery, as you simply cannot legislate for the myriad of problems that these types of drives can incur. After canvassing opinion both off and online, the general consensus seemed to be that out of the three most common manufacturers (Seagate, Freecom and WD), Freecom HDD's were, generally, slightly more stable and reliable than the others. So, after spotting this 500GB model for under £80, I decided to go for it.
The drive is solid, quite weighty, and approximately the size of a VHS tape (albeit slightly thicker). The installation process is basic and only requires the connection of a power lead, and a USB chord - the help manual comes on a CD.
After the initial set-up, I checked the properties of my new HDD, and was pleased to see that the drive used in my new HDD was a Samsung HD501LJ model. It had been mentioned to me previously that Samsung drives were usually pretty reliable, and thus I felt even more pleased about my new piece of kit.
As far as daily use - so far, so good! It's on almost 24/7 and everything has worked as it should. It transfers 4GB of VOB files in about 6 minutes, runs warm to very-warm, sits in almost complete silence on my desk, and looks rather smart in jet-black, with only its small blue LED light giving any indication of activity. The only thing I've changed on the HDD is the file system, which, when it was delivered, was pre-formatted to FAT32 (apparently enabling broader compatibility with older versions of Windows). I reformatted to NTFS which took just over an hour, as this file system is more up-to date and is able to cope with meta-data on media files, which FAT32 cannot.
Highly recommended.
