n1-standard-4 Intel Skylake NVME SSD by Google Cloud

Bandwidth testing are conducted with local and block storages attached to the instance. We use the well-known open-source tool FIO. To express bandwidth the following parameters are used:

1M block
Sequential access
No filesystem (except for write access with root volume)
Avoidance of cache and buffer
