Real World Benchmark Lenovo Legion Go Z1

[johng]

For anybody who stumbles across this on whether to buy Primocache, here are my real world benchmarks from 3DMark Storage benchmark on my 2TB upgraded NVMe model with 16GB memory (connected via Thunderbolt 3 to an AMD Radeon RX 6900 XT).

Disks are listed in the benchmark images, but Dockcase has a 512GB 2242 NVMe that came out of the Legion Go.

Crystaldisk is not a great benchmark for this, as it's either ridiculously max performance if the test file all fits in L1 cache or just normal disk performance if it doesn't, hence why 3DMark simulates real world tasks.

* Installed Primocache Pro (trial) on Windows 11 Enterprise IOT 2024 LTSC (x86_64) - Low memory footprint OS
* Created an L1 of only 1GB of memory
* Created an L2 of the 512GB on the external USB4 NVMe
* Selected Preset Profile: Accelerated Read
* Changed Profile to disable Deferred Write Caching
* Only enabled the caching of the Western Digital Black 8TB (Normal performance benchmark is around a sequential throughput of 250Mb/s)
* Ran the benchmarks specifically for this on the WD Black 8TB, after Benchmark first, then disabled Primocache and ran the Before benchmark in that order

Low L1 cache as the Legion Go shares memory with the dGPU, however with the eGPU doing the heavy lifting I still kept it set low, as without the eGPU I wanted to see how it performed.

You should uninstall and clean reboot before you do the "before" benchmark, to prevent measuring of caching done by Windows and to prevent measuring effects by having Primo Cache installed.
