## Appendix D. Solid State Drives (SSDs)

If you are planning on using Solid State Drives (SSDs) for your Oracle NoSQL Database deployment, a special consideration should be taken. Because of how SSDs work, I/O latency can become an issue with SSDs over time. Correct configuration and use of `trim` can help minimize these latency issues.

## Trim requirements

In general, for TRIM to be effective, the following requirements must be met:

- The SSD itself must support trim.

- Linux-kernel 2.6.33 or later.

- Filesystem ext4 (ext3 does not support trim).
