Newegg offers the SanDisk 240GB Ultra Serial ATA 6Gb/s Internal SSD, model no. SDSSDHII-240G-G25, for $92.99 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $17, although we saw it for $3 less last month. It features up to 500MB/s write and 550MB/s read speeds.
Note: If you haven't yet, use Newegg’s Android app and pay using Google Wallet to cut it further to $77.99. (This discount can only be used once per account.)
