REVIEWS ADDLINK S70 NVME SSD


512GB model (currently $67
on Amazon [go.pcworld.
com/s512]), and a 2TB model
(currently $269 on Amazon
[go.pcworld.com/s2tb]). Yes,
you pay a bit more per
gigabyte for the max capacity,
but it’s still darn inexpensive.

PERFORMANCE
In the synthetic benchmarks,
the S70 gave the best drives
I’ve tested a real run for the
money. The fact that it slows
down after it runs out of
cache to just under 1GBps
during sustained writes left it
slightly behind. But only a
couple of drives sustain
faster than that, and I’d
hardly call that rate slothful.
The S70 is a very fast
drive, and you’d be hard-
pressed to tell the difference
with the naked eye between
the WD SN750 Black NVMe
and the Samsung 970 Pro to
which I compare it.
The S70’s
CrystalDiskMark numbers,
shown above (gold bars),
measure sustained
throughput with relatively
small amounts of data (1MB).

Though it’s not the world-beater CrystalDiskMark makes it out to
be, the AddLink S70’s numbers aren’t that far off the mark.

Slowing down to just under 1GBps during long sustained writes and
other realities mean the S70 can’t quite match Samsung’s 970 Pro, or
even WD’s SN750 Black, but for the price it’s a darn near thing.
