Newegg offers the Adata 480GB Ultimate SU650 3D NAND 2.5" Serial ATA 6Gb/s Internal SSD for $49.99 with free shipping. That's $2 under our last month's mention and the best deal we've seen. (It's the lowest price today by $3; although most sellers charge over $60.) It features read speeds up to 520MB/s and write speeds up to 450MB/s. Note: It's on backorder but can still be purchased at this price for delivery when available.
