wise choice, that's a backup drive for like nightly backups.. one big write every once and a while.
most drives can last very long times when used as an archive drive, simply because they sit parked almost always until a backup kicks in.
using standard desktop drives for video recording is acceptable, but archival grade storage is along the lines of flash memory, optical media, magnetic tape.. light duty cycle and long life.. not really any need for a ton of that for surveillance video @ 100% duty, most interesting clips worth keeping are just a few hundred megs.
back when we had to use analouge tapes for video recording, surveillance systems would wear the stuff to dust.. alot of quality issues were due to tapes that been recorded over a thousand times.. imagine your recordings slowly getting worse with time, ugh.
harddrives are complicated beasts with there own lil operating system running on them, when a drive controller has very specific software designed for one task its a very bad idea to try to make it to the exact opposite.. just going to end in tears... it works the same way when people use surveillance grade disks in desktops/gaming rigs.. they fail alot quicker than a normal drive would have because they gave it a duty load it was not optimized for.
General Duty drives work well for most all tasks, specific duty drives should not be 'beta tested' unless you have more money than sense.
