## Overview

The iXsystems TrueNAS Mini Write Cache (ZIL) Upgrade is a 2.5-inch SATA SSD designed to dramatically enhance write performance and reliability on TrueNAS Mini systems. Leveraging TrueNAS’s advanced ZFS Intent Log algorithms, it securely caches critical data to prevent loss during power outages. With a 16GB effective cache size backed by a 480GB overprovisioned SSD, this developer-certified upgrade ensures both speed and endurance for professional-grade storage solutions.

## Description

Write Cache (SLOG) upgrade to increase the performance for your TrueNAS Mini.

Review: Does what it's supposed to do - One note - if you are new to TrueNAS this write cache is 'over provisioned' and only shows up as a 16GB in size even though it's a 480GB SSD under the covers. The way ZFS Write cache works is that it's cacheing each stripe to this device and then the device writes it to disk immediately. So only 16GB or so is needed but it is rewritten much more than standard SSD, so over provisioning is used so that there is lots of spares as over time this will wear out faster than a normal SSD usage.

## Features

- Boost write performance and reliability on your TrueNAS Mini with a dedicated ZFS Intent Log (SLOG) device.
- Take advantage of TrueNAS’s advanced algorithms to hold critical data waiting to be written in the SLOG until confirmation of a successful write is received. Never lose data waiting to be written to ZFS, even in the event of power loss.
- Hardware tested and qualified by the developers of TrueNAS.
