the read speeds are correct on userbench but the write speed is wildly inaccurate when tested next to crystal disk.

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.

Amazing performance for the price and solid reliability.

Western Digital replaced TLC with QLC NAND in Blue SN550 (recognizable by firmware id 233010WD). This is why the peformance shows terrible consistency. The new SN550 with TLC performes significantly worse then the old one. WD is supposedly offering a free replacement.
