If you're looking for a significant performance boost for your middle-aged laptop, replacing your aging hard disk with a solid state disk (SSD) could give your computer a new lease on life.

Solid-state disks (pictured, bottom) differ from traditional hard disks (top) in that they're not constructed with platters and heads. Instead, they're more like giant thumb drives, containing memory chips designed to be written and re-written without wearing out. The upside to this is that SSDs are much, much faster to read and write to, making booting and starting applications lightning-quick.

I recently installed an Intel X25-M SSD, a 160GB drive, as a replacement for a 120GB Toshiba hard disk for my 2006-vintage black MacBook. Spendy, for sure, but for the performance increase and the extra life it adds to my MacBook, well worth it. Plus, I had my state tax refund burning a hole in my pocket.

The performance is phenomenal. The old disk booted in a respectable one minute, 49 seconds. The new disk booted in a blazing 31 seconds. Ridiculous. Windows also boots in less than half the time it took before. Photoshop CS3 launches in five seconds, Illustrator CS3 in nine seconds.

Getting the drive was simple: It's moving the data that takes time. Read on to see how you can migrate your data like I did -- including a Boot Camp partition -- with little fuss.

Peripheral maker Belkin has taken note of the fact that a lot of people are switching to Macs. Their new Switch-to-Mac USB Cable, available in the US now for US$49.99, is designed to streamline the process of moving files from your PC running Windows XP or Vista to your Mac running Tiger or Leopard.

The cable comes with a Migration Assistant that performs a similar function to Apple's Migration Assistant -- it copies music, movies, photos, files, and Internet preferences from the PC to the Mac at USB 2.0 speeds. At the completion of the migration, the software provides a summary of all of the content that has been copied and the location of the files.

Belkin says the Switch-to-Mac USB Cable is on sale in the US now, and it will be available in Canada, Asia, Europe and Australia beginning in February, 2009.
