QNAP

QTS 5.0.x

Disk Types

QTS restricts which type of disk can be used to create SSD cache, storage pools, and static volumes.

Important:
  • For compatibility reasons, PCIe form-factor SSDs and PCIe M.2 SSDs installed in third-party adapter cards cannot be used to create storage pools and static volumes.

  • If you are already using NVMe PCIe SSDs for data storage, then your existing storage configuration will not be affected after upgrading to the latest version of QTS.
