Toshiba has been a leader in the consumer electronics industry for as long as I can remember. Founded more than 70 years ago, this Japanese company manufacturers everything from tiny electronic components to consumer products like televisions, Blu-ray players and personal computers. Toshiba is no stranger to the storage industry either. The company designs and manufactures high-quality flash memory-based storage solutions, SSDs and hard disk drives for the consumer and enterprise markets.

This past fall, Toshiba launched its Q Series Pro SSD. Available in capacities ranging from 128GB up to 512GB, this ultra-slim drive is ideal for avid gamers, graphics professionals or anyone else looking to boost their computer's storage performance to the next level. With no moving or mechanical parts, the Q Series Pro is more rugged, quieter and consumes less power than standard hard drives. Also, with Toshiba's TC358790XBG controller and 19nm Toggle mode MLC NAND flash, the drive is able to deliver faster boot up speeds, shorter application load times and improved system responsiveness.

For this review, we purchased the 256GB version of the Q Series Pro. This drive is capable of delivering up to 554MB/s sequential read and 512MB/s sequential write speeds as well as up to 90,000 random read and 35,000 random write IOPS.
