Lenovo ThinkPad T470 Ultrabook running Linux – Part 4 – Benchmarks

Disk Benchmarks

Non-Volatile Memory Express (NVMe) is the latest industry-standard software interface for PCIe SSDs. NVMe enables drives to benefit from the same “pool” of lanes that directly connect to the CPU. PCIe 4.0 drives can offer in excess of 7,000MB/s reads and 6,500MB/writes (with very large files). We don’t find this technology on refurbished machines.  But even with the older PCIe technology, we can get read speeds in excess of 3,000MB/s and write speeds over 2,000MB/s.

You can see a clear difference in performance when you use NVMe, with a read/write throughput far higher than the hard drives and slower SATA SSDs also lagging somewhat behind. But it’s not always a huge difference.

The T470 has an NVMe but its performance is not great by current standards.

The GNOME Disks benchmark, of course, is a synthetic throughput that rarely corresponds with reality.

We wanted to verify the GNOME Disks tests. We therefore performed an extra disk speed test with dd. Note that we are using a blocksize of 1 MiB (whereas the GNOME Disks test is using a different sample size).

$ sync; dd if=/dev/zero of=tempfile bs=1M count=1024; sync
$ sudo /sbin/sysctl -w vm.drop_caches=3
$ dd if=tempfile of=/dev/null bs=1M count=1024

The chart below shows the findings (the test on each machine was run 5 times).

We didn’t test write speed. Remember, you cannot unmount a filesystem that’s in use. And the GNOME Disks write benchmark is destructive.
