My experience with hard drives:

I run well-ventilated mid-tower Linux-based PCs with plenty of space for 
extra internal hard drives. Internal hard drives tend to work year after 
year. My MythTV recordings drive is internal to such a PC and has been 
glitch-free for the 3+ years it's been installed.

Regarding external USB drive enclosures, I've done OK with single-drive 
enclosures. What has _not_ worked well for me has been dual-drive 
enclosures. I've tried several dual-drive enclosures (with an exhaust fan) 
with two matching hard drives set up as a RAID 1 array. More than once, 
I've had one of the two drives fail within a week or two of the 
enclosure's initial installation. Up to now, I've attributed this to 
faulty enclosures.

So, I've stuck with single-drive enclosures until my recent acquisition of 
a LAN-attached dual-bay Synology NAS. What made me decide to try a 
dual-drive enclosure again was my discovery that some models of hard 
drives, especially the cheaper drives that are sold for home use, are 
prone to premature failure when installed in a high vibration location 
such as the dual-drive USB hard drive enclosures I'd tried before. So, 
this time around I spent some extra money for a pair of hard drives that 
are marketed specifically for use in NAS enclosures. These drives are made 
with anti-vibration technology that's supposed to help them run reliably 
in a high-vibration environment such as a multi-drive enclosure. I've been 
running this NAS for nearly 3 weeks without any hard drive issues so it's 
already outlived at least two of my older USB dual-drive enclosures. 
Hopefully the anti-vibration technology of the hard drives plus the 
Synology enclosure's exhaust fan will help these hard drives to last at 
least a few years.
