RamCache – Fact or Fiction
Setup:
Test HDD Drive: Toshiba X300
5TB Desktop 3.5 Inch SATA 6Gb/s 7200rpm Internal Hard Drive
PC Specs:
CPU:
Intel Core i7 6700K 4.00 GHz (no OC)

Initial Test:

Benchmark after RamCache:
Initial Copy after RamCache(48.34 seconds):
Some
random files were copied to ensure that cache is flushed.
Same
result as no RamCache. As nothing is cached yet, normal read speeds expected.
This
is where the main advantage lies. Once cached, access times are going to be
leaps faster. The speed bottleneck here is probably my main drive.
What about writing to the HDD (6.35GB):
Without
RamCache (30.74 seconds):
The initial high
shows the existence ~2GB of default cache.
With RamCache (11.26 seconds):
A
more consistent performance due to higher cache amount, expect this to go down
when the cache runs out like the previous test.
