Note: The connected drive may not reach its optimal performance due to protocol translation and some overhead.

SAS dual-port advantage for fault tolerance

SAS features dual porting for redundancy, eliminating single points of failure and allowing for higher reliability and performance. By installing a SATA drive with the QDA-SA3 into a dual-controller all-flash Enterprise ZFS NAS, the SATA drive can share these SAS dual-port advantages to ensure a high-availability, fault tolerant enterprise storage environment.

Designed for all-flash Enterprise ZFS NAS

The QDA-SA3 can be easily installed in the 2.5-inch disk tray of an all-flash array Enterprise ZFS NAS (ES2486dc disk tray model: TRAY-25-NK-BLK04).

Note: QDA-SA3 does not support SSD TRIM and the drive S.M.A.R.T. feature is not supported on non-QES operating system.
