SSD Benchmark results

[enkoda]

Just for kicks I decided to use CrystalDiskMark 7.0.0 x64 to do some SSD benchmarks across these machines:

PC - i5-4670K, booting off a Samsung 840 Evo 120 GB
Laptop 1 - HP Elitebook 8440p, i5-520M, Integral P Series 4 120GB SSD
Laptop 2 - Dell E7270, i7-6600u, WD Green 240GB M.2 SSD

I didn't get screen shots, so I hope this is readable enough....

PC:
SEQ1M Q8T1 - Read=545.40 Write=532.25
SEQ1M Q1T1 - Read=522.31 Write=512.67
RND4K Q32T16 - Read=393.81 Write=217.80
RND4K Q1T1 - Read=39.84 Write=93.22

Laptop 1:
SEQ1M Q8T1 - Read=258.36 Write=255.82
SEQ1M Q1T1 - Read=233.61 Write=191.88
RND4K Q32T16 - Read=203.50 Write=128.60
RND4K Q1T1 - Read=13.47 Write=18.64

Laptop 2:
SEQ1M Q8T1 - Read=411.24 Write=265.48
SEQ1M Q1T1 - Read=395.94 Write=306.56
RND4K Q32T16 - Read=9.32 Write=36.57
RND4K Q1T1 - Read=5.75 Write=9.96

Any ideas as to why Laptop 2 has such abysmal RND4K speeds, despite it being significantly newer than the other two machines and using a faster interface?

The WD Green is a SATA SSD in an M.2 format, isn't it?

And given where Green drives usually drop into WD's drive line up I don't expect it's going to be the fastest SATA SSD either.

I didn't even consider that, I just thought "oooh M.2 drive, happy days" - the laptop doesn't even seem "sluggish" although tbf I don't use it a lot.

Even if it is a green SSD in M.2 clothing, is that the really the best I can expect?

I don't know if your figures are typical for that drive or not. From a very superficial search, it appears to be a cacheless drive which would mean that its performance is going to be limited.

I'd just use it and avoid running benchmarks if I was you.

No worries, it was something to pass a few minutes in the calm of not getting shot at by Nerf guns!
