Fast, reliable.

On par with all the greatest.
Bit hotter than other PCI-e 4x on IDLE. But still less than Patriot Viper or KC3000.
I would recommend this to a friend!

Fast, good quality. Although now there are new products like pcle 5.0*4, SN850X is still good enough for daily gaming and working.

I ran out of storage on my iMac, so I purchased 2 of the WD Black SN850X 4TB SSDs. I use one as my main storage and the second is my TimeMachine backup. Speed tests confirm these SDDs are FAST R/W speeds! Very impressed and happy.
