highest of any drive overall and for writing
other than Intel’s 905P, a super-expensive
Optane drive.
However, there was one slowdown to
about 1GBps during the 48GB single file
write test that stumped us. This is usually an
“Aha! It ran out of cache” moment that’s
mirrored when we write 450GB to the
drive. However, aside from two momentary
and less significant dips in speed, the drive
never slowed down in the same
fashion during the 450GB write
tests. Go figure.
You can see the phenomenon
in the two screen caps below the
test results. The dark green bars
show the FireCuda 510’s
performance.
AS SSD 2 thinks the FireCuda
510 is a beast (in the good sense),
and it is during everyday
performance.
As you’ll see below, the
FireCuda 510 is better with large

groups of small files than with single large

files, though it’s not too shabby with those

either.

The FireCuda 510 dipped to around a

1GBps transfer rate at the 30GB mark during

our 48GB single file write. It stayed there, but

look at the next screen cap.

When given an even larger 450GB file

to write, FireCuda 510 dipped from its

normal 1.8GBps performance only a few

As you can see the Samsung 970 Pro has little on the FireCuda

510 in CrystalDiskMark 6.
