Dell Small Business offers its Dell 256GB Serial ATA 6Gb/s 2.5" Internal SSD Upgrade Kit for Dell Desktops and Notebooks bundled with a $50 Dell Gift Card for $159.99 with free shipping. (The gift card will arrive via email 10 to 20 days from ship date.) Assuming you'll use the gift card, that's a savings of $120 and the lowest price we could find, although we saw it for $25 less in June. The kit includes a 256GB SSD, 2.5"-to-3.5" desktop adapter bracket with screws, 7mm-to-9mm laptop adapter, SSD enclosure, USB 2.0 cable for enclosure, SATA cable, and power cable. Deal ends September 18.

Note: This kit is only compatible with the models listed under "Compatibility" on the product page.
