There is no 1tb sandisk on stock but i can go with mx500 is this better ?Skip the Crucial. Its a QLC drive and will drop to being as slow as an HDD when you fill the large buffer. The buffer size varies with how full the drive is since it is using empty cells of the SSD in SLC mode.
The 860 is the quickest of the bunch, The Blue and the Red are very close. I would not overlook the Sandisk Ultra 3d (same drive as the WD Blue 3d) or the Mx500 if their prices are equivalent.
Thank u for helping i will buy mx500The Mx500 is the 2nd best of all the current Sata SSD's in my opinion.
