Also, bigger plates, mean more time reading the same place. When you have 4 drives, you divide the point of failure, so if your 40GB drive dies, you only lose access to 40GB, which very likely you could recover with GetDataBack for NTFS.
Basically, a drive will last an X amount of hours which are influenced in the condition of the drive (heat, dust). This is normal since HDD are mechanical, so they suffer from wear off.
At Veronica, external drives (just are internal) can get damaged with heat, however there is better airflow inside the computer case than inside the external enclosure. Disabling the indexing on the external drive will reduce the amount of reads that the drive would have. I always disable index for my PC (not just external drives) since I never use it (twice a year I search for files, and I prefer to wait 30 minutes than to reduce 300 hours from my drives).
357, a big advantage of having 4 drives, is that you have 4 independent I/O, so lets say your OS is in the 40GB, then your music in the 80 GB, Videos on 120GB and programs and games in the 100GB, you could play a video game, and your own music with a less performance impact that if everything was in 1 drive.
I actually do that with most of my PCs, and I even go one step further by placing the virtual memory in a separate hard drive (sometimes in the same drive as the music).
If you are worried about losing data, then I would suggest that you get 4 drives the same size and set them up in RAID 10, so 4 500GB would give you 1 TB stripped and mirrored storage. and you can go another step by setting another external drive to put data outside the RAID.
