Question about Seagate Exos X18

The Seagate EXOS X18 (16 TB, 3.5", CMR) with product ID ST16000NM000J is not officially listed in the Synology compatibility list, but it can still be used in a Synology NAS such as the DS723+.

- There are reports that these hard drives work in Synology NAS systems even though they are not on the compatibility list. However, there may be system warnings in the DSM (DiskStation Manager) software.
- It is important to note that the use of non-Compatibility List hard drives in certain Synology enterprise-class products may affect support. It is advisable to contact Synology support directly, especially for higher end devices.

Overall, the EXOS X18 hard drives are technically compatible, but there may be slight limitations and warnings.
