I have the 512G model and considering swapping to the 1TB as people are reporting 20% faster speed.
Here are some specifics from numbers i've compiled:
Surface Book 1TB v Surface Book 2 512g:
= 27% faster on sequential reads and 87% faster on writes
= 2% slower on 4KiB Q32T1 reads and 13% faster on writes
= 7% slower on 4KiB Q32T1 reads and 18% slower on writes
= No change on 4KiB Q1T1 reads and 31% slower on writes
Samsung PM961 512g v Surface Book 2 512g
= 73% faster on sequential reads and 131% faster on writes
= 110% faster on 4KiB Q32T1 reads and 250% faster on writes
= 100% faster on 4KiB Q32T1 reads and 39% faster on writes
= 39% faster on 4KiB Q1T1 reads and 82% faster on writes
Samsung 960 Pro 512g v Surface Book 2 512g:
= 86% faster on sequential reads and 225% faster on writes
= 93% faster on 4KiB Q32T1 reads and 374% faster on writes
= 144% faster on 4KiB Q32T1 reads and 50% faster on writes
= 37% faster on 4KiB Q1T1 reads and 87% faster on writes
Has anyone managed to get decent performance from it? Its way slower than the PM961 or Samsung 960 Pro
