Okay, this looks good for a few reasons. First, we are easily exceeding factory sequential specifications for both read and write. Second, this is significantly better than the 660P, so we already see indications that the 665P is indeed faster than the 660P. Additionally, look at that QD1 read - it's fantastic.

The drive's 4-channel Silicon Motion SM2263EN controller doesn't deliver the eye-popping numbers that we see with 8-channel controllers. However, what it does do brilliantly is deliver speed where it really matters. Where it matters most, 4K read, we are seeing 16,637 IOPS. That is a massive number that we don't often see.
We love it when a drive exceeds factory specs for random read. This is what we see in a huge way with the 665P 1TB.
