Not all portable computers have sata drives, some use ide drives which do
have a data cable.
Most portables using mechanical hard drives can be upgraded with drives
which are faster, as the article indicates.

Hello,
This thing is talking about notebooks and notebook upgrades. But yet
it talks about unscrewing a bottom pannel and disconnecting cables.
The notebooks I've had the pleasure of working with do not have any
cables and use SATA drives. Also, the majority of notebook drives are
5400 or 7200 RPM drives. Am I missing something?
Thanks

Notebook Upgrades: Storage
Hard drives are all about storing and accessing data: You want to store
as
much of it as you can, and you want to access it as quickly as possible.
Therefore, capacity is not the only important criterion; speed is also a
consideration. Replacing a hard drive is normally not much more
complicated
than adding memory: Remove a bottom panel, remove the screw(s) holding
the
drive in place, carefully disconnect the power and data cables from the
drive, and gently remove the drive from the drive caddy.
Hard drive sizes have jumped dramatically in order to accommodate the
proliferation of enormous (and enormously powerful) applications and the
gigantic video, audio, and image files we now use on a regular basis.
These
days, a 120GB or larger drive is standard in a notebook, and 250GB is not
uncommon. In addition to size, drives are rated according to how fast the
platters-the magnetic disks on which data is stored-spin. Today's drives
typically spin at 7,200rpm or better, and many spin at 10,000rpm. The
faster
the drive spins, the more quickly data can be retrieved, assuming that
the
drive's head mechanisms can move to the correct place on the platter and
find the appropriate data. That component of a drive's performance is
known
as "seek time," and it's measured in milliseconds; it's one of the specs
you'll want to consider when looking at new drives. A drive with a 12ms
or
13ms seek time is typical, and plenty fast enough for most of us. A
faster
drive requires more sophisticated head mechanisms and more efficient
software, which helps explain why faster drives cost more than slower
ones.
