You aren't comparing apples to apples. You aren't even comparing apples to gorillas.
First, you would need more than one hard drive. You would need to buy at least two hard drives(even two may expose you to more risk than you desire). Even if you do opt for just two, and do manual mirroring, it now takes two years to catch up with glacier.
Second, $240 upfront is more costly in this environment than putting $10 up per month for 24 months. Glacier costs will very likely fall over two years, and that fact will be reflected in your statement at the end of the month. HDD costs will fall over the two year period, you can't utilize any of these lower rates, since you've already sunk your capital into two outdated hard drives.
Third, glacier is designed to have data constantly written to it, and only infrequently read from it. This is difficult to pull off with external hard drives that you have locked in a safe at the bank.
