Over the past year ADATA has released a number of different solid state drives aimed at different market segments. Not that long ago we took a look at ADATA's XPG SX930 which was aimed at gamers and enthusiasts. Today we will be taking a look at the Premier SP550 which sits as ADATA's entry-level solid state drive aimed at people who are looking to upgrade to an SSD and still want very good performance. The drive features the Silicon Motion SM2256 controller matched with SK Hynix TLC NAND. This is the first time we?ve seen this combination together. The 240GB version of the drive that we are reviewing today boasts sequential read and write speeds of 560 MB/s and 510 MB/s respectively. Let's get this drive on our test bench and see what it can do!
