Why, Ah remember when my bosses at a job long ago gave me a *big*, brand
new drive as a holiday gift, knowing I'd be working at home. Why, it was
all of 30MB!

Sorry, the 750GB's are going, going, gone, and even the 1TB's are
"smaller", except for the HPC clusters, which don't need a lot of disk.
And no, I do not toss my backups at work in my shirt: the offline backups,
fully encrypted disks, go in the fire safe in the locked server room. Some
of the systems they're backing up have HIPAA and PII data.
