Introduction:::...
If
you've taken even a passing interest in notebook prices
over the past 12 months or so you can't help but have noticed
the plummeting prices. This isn't happening because manufacturers
are stripping out features, in fact quite the opposite is
true with even budget units offering CD Writer/DVD-ROM combo
drives and 30GB plus hard drives. It's in fact a rather
pleasant side effect to advances in miniaturization and
maturing manufacturing techniques which relegates last year's
"bleeding edge" technology this year's "nothing
special".
Of
course, as prices have fallen and capabilities have climbed,
so more and more people, who would in the past have spurned
the notebook for its limited usefulness, are suddenly seeing
all kinds of possibilities opening up to them. And as more
people buy, so prices fall, and we all like falling prices.
Not
too long ago I was lucky enough to get hold of one of Toshiba's
100GB MK1031GAS hard drives to test, and was genuinely impressed
with its very impressive performance which was no doubt
helped by its industry-leading areal density of 80 gigabits
per square inch.
Today
I have the MK1032GAX for review. While this shares the same
100GB capacity and impressively low power requirements,
it adds a further 8MB to the MK1031GAS's already generous
8MB buffer making it a monstrously large 16MB in size, and
they've also cranked up the rotational speed from 4200rpm
to 5400rpm!
Much
of the information for this hard drive was covered in my
review of the MK1031GAS, but rather than send you over there
to read it I've zapped it over here, that way you can just
skip the bits you've already read.
In
other respects the two drives are very similar. As usual,
