Mean Time Between Failure (MTBF) for hard drives is a traditional and
probably useless measure of drive reliability
. From my experience HDs may be expected to
fail after 3-7 years of being on mostly 24x7, that is, not being
turned on/off a few times a day. You might buy an enterprise-quality
HD (e.g. http://tinyurl.com/3nlu26)
for more reliability.
Flash drives do have a limited write life. A wikipedia article
says flash USB drives
"have built-in controllers to perform wear-levelling" which will help.
Googling turns up the usual ambiguous contradictions, 100K write
cycles are often cited without attribution. I'll speculate that a USB
flash drive that works with Vista ReadyBoost to supplement the PC's
RAM might be designed to support lots of write/erase cycles.
OK, I haven't come up with any hard numbers. Maybe we can simply say
HDs might last longer than flash memory. How are you expecting to use
your Slug? If you need lots of storage (more than say 8-16 GB) then a
HD is probably your only option and makes the decision easy. I am
going to use my Slug mainly as a proxy server and maybe to serve a few
files (photos, etc) for a limited audience (family). So I'm going to
use a 4GB flash drive and see how it works. Other advice posted about
making backups is always good.
