    A good buy if it's 30% or more off List Price, but will look else were if priced higher.
    I bought the 4TB at 38% off the list price, and for that price for a 4TB SSD it was worth the cost. However SATA3 SSDs that have a controller chip all do a similar job overall with just benchmark scores showing the little difference between them all (check picture and compare.) It really just comes to price & warranties that set these apart, but for me it's price. With that said their are other brands that have a better prices yet still perform just as good as WD SATA3 SSDs so your just paying the premium for a brand name & a hit or miss warranty (just look at other reviewers take on it.) I will only recommend Western Digital SATA3 SSDs when they are on sale that is on par with other budget brands.
