Getting Started
We tried various combinations of I/O drives for relative performance, with the following results:
| Model | Capacity | Cost | Relative Performance |
|---|---|---|---|
| Sandisk Ultra SDCard A1 | 32GB | $7 | 1,078 |
| Sandisk Ultra Fit USB flashdrive | 128GB | $19 | 1,393 |
| Kingston A400 (+cable) | 120GB | $32 | 7,533 |
| WD Blue SN500 NVMe (+adapter) | 250GB | $94 | 7,912 |
N.B. a larger Kingston A400 with 240GB capacity is available for $42 including the USB<->SATA cable.
Full details of the I/O benchmark are available on our I/O benchmarks page.

Documentation is written in markdown using the Ghostwriter markdown editor.
It is rendered using the Hugo static site generator and makes use of the simple Whisper theme for style, which will be modified slightly in due course. Deployment is via rsync.
