Hard Disk Storage

External Storage media is getting more and more affordable. You can find a 1 TB portable USB hard drive for a little over $100. I favor the Seagate GoFlex hard disk. The WD Passport hard drive is popular, and right now is the smallest form factor (and includes a soft case).

The drives have increased in storage capacity from smaller drives, then 500 GB to 640 GB to 750GB to 880 GB, then to 1 TB. The Iomega 500 GB is the largest portable deive with Firewire 800 connectivity.

Firewire 800 and USB 2.0 are the available connectors for peripherals on the current Macs. Apple dropped the Firewire 400 port in most of the latest models. Converter cables are available from Firewire 400 to 800. Seagate has different hard disk end connectors to add Firewire 800 connectivity. USB 3.0 drives are starting to show up on this market, but this standard is not supported on the Macintosh yet.

The original internal 2.5 inch SATA drive can be removed and replaced with a drive of higher speed and capacity. An original 120 GB, 160 GB or 200 GB drive can be replaced with a 500 GB 7200 rpm hard drive. This upgrade will add new life to your old MacBook Pro for about $100. The best performance drives are Seagate 500 GB 7200 rpm, with a 750 GB 7200 rpm now available. Even better performance is the Seagate MomentusXT 500 GB solid-state hybrid 7200 rpm drive, which remembers computer start-up instructions and learns to work faster.
