Lol, about 25 days to blast through the drive's 650TiB life. It kinda embarrasses all the other drives tested here.

However, it certainly does look like your 830 is performing more normally then the previous 830 tested. 600TiB is my conservative estimate for the drive life of a 256gig drive with 3000 cycle NAND, and your 830 is going a bit beyond that.
