I've seen a report from a datacenter which uses thousands of customer hard disks. In their report HITACHI had the lowest failure rate from all other brands. Also within our company HITACHI is very popular for its reliability and support.

e.g.

Hitachi Travelstar 5K1000 1TB - about 60$ - silent too

In that report mentioned above, also some of the WD disks were good.

But generally you should go for Enterprise class disks if you need reliability. The manufacturers specifically sell those as "Enterprise Class" disks, mainly for 24 hour, 7 days a week for use in a server in RAID arrays. But as these disks are built for use within servers which are normally inside an air-conditioned, noisy server room, they aren't built to be quiet, so that can be a drawback.

Besides, even the most reliable disk will fail eventually, and they might fail even soon after you first use it. So whether you use a reliable or not so reliable disk, you must still have a good backup strategy in place. There is no insurance that it'll not fail.

If you want reliability, do Not put your drive in a USB drive case that can be knocked over or have stuff put on it.  I have had customers go thru several drives simply because they kept knocking them over and breaking them.  In addition, the power supplies in most of those cases are not very good.

Put it in Amazon Glacier - cheap as chips, really slow but you'll never have to worry about the drive breaking - way more reliable than a single hard disk.

Google have an (old) report here:
http://static.googleusercontent.com/media/research.google.com/en//archive/disk_failures.pdf
it's an interesting read, albeit quite old.  Points to deal with:
hardware items have a "bathtub curve" failure rate, generally - ie initial high fails due to teething troubles, then low failure rate (gently increasing), and finally an increasingly high failure rate as the end of service life is reached.  
You have no way of knowing (without extensive burn-in testing) which category you'll be in.  

So, buy a known big-brand, BACK IT UP, and use monitoring controls to measure its availability.  Test your Restore functionality, under a worst-case scenario - ie total raid failure, bare-metal OS recovery, etc.
