How to Switch to a Solid-State Drive
By Patrick Miller, PC World
Prices on solid-state drives are dropping, and operating systems (particularly Windows 7
) are beginning to take advantage of the potential higher speeds of SSDs, so it's a good time to consider slapping one in your computer.
Though SSDs tend to be faster overall than hard-disk drives, their speed advantage doesn't hold across the board. Normally an SSD reads data at a much quicker rate than an HDD does (Intel claims that a typical HDD takes 4000 microseconds to access your data, versus the advertised 65 ms of the company's 160GB X25-M
SSD model); but an SSD's write speeds may be slower than those of a 5400-rpm HDD.
