## Preparation
- Get some SATA or NVMe SSDs with capacitors (server-grade drives). You can use desktop SSDs
with lazy fsync, but prepare for inferior single-thread latency. Read more about capacitors
[here](../config/layout-cluster.en.md#immediate_commit).
- Get some SATA or NVMe SSDs with capacitors (server-grade drives). The best performance
is achieved with Micron or Kioxia NVMes with atomic write support (see below). You can use desktop
SSDs with lazy fsync, but prepare for inferior single-thread latency. Read more about
capacitors [here](../config/layout-cluster.en.md#immediate_commit).
- If you want to use HDDs, get modern HDDs with Media Cache or SSD Cache: HGST Ultrastar,
Toshiba MG, Seagate EXOS or something similar. If your drives don't have such cache then
you also need small SSDs for journal and metadata (even 2 GB per 1 TB of HDD space is enough).
