Great SSD for the price. Not sure why the rankings/% is messed up though

Very modern day SSD with plenty of quick and good value storage. Just bought it for 125$ CAD and it's incredibly quick and Its great value. The advertised speed is 2400mbs (2.4GB) with a 5-year warranty. Definitely one of the best value SSDs on the market.
