These days, you can pick up a 7200rpm, 1TB laptop hard drive for a little more than $100. (Of course, hard drive prices have also plummeted. This isn't unexpected in January 2012, research firm IDC predicted that prices of SSDs would tumble this year.
For example, Crucial in July announced its new low-cost v4 SSD that costs $100 for a 128GB model and $190 for a 256GB model. Today, however, SSDs cost close to one-third of what they did in 2009 - in many cases, less than $1 per gigabyte. If you were paying $700 for a laptop, it wasn't reasonable to expect to pay almost half that for a new drive. That meant a 120GB SSD cost you more than $300. In 2009, SSDs cost around $3 per gigabyte. Perhaps the single biggest change, though, is price. In addition, in adherence to Intel's new ultrabook computer specifications (PDF), manufacturers are beginning to produce laptops with two drive slots, one for a hard drive and the other for a low-capacity cache SSD which works with hard disk drives to speed up boot and application load times. For example, hybrid drives combine NAND flash cache memory with a spinning disk in a hard-drive form factor.
