4-bay 1U short-depth rackmount NAS
QNAP TS-h765eU-8G
A space-saving QuTS hero NAS with four SATA drive bays, three E1.S/M.2 NVMe slots, DDR5 memory and dual 2.5GbE connectivity.
Compact rackmount storage with flexible flash expansion
The QNAP TS-h765eU-8G is a 1U short-depth rackmount NAS designed for space-constrained cabinets and wall-mount racks. It runs the ZFS-based QuTS hero operating system and combines four 3.5-inch SATA bays with three E1.S slots that include pre-installed adapters for M.2 2280 NVMe PCIe SSDs.
Key features and benefits
Short-depth chassis
The 292.1 mm depth is designed for smaller media cabinets and wall-mount network racks.
DDR5 with in-band ECC
The supplied 8 GB DDR5 module has in-band ECC enabled, with a stated maximum memory of 16 GB.
Flexible NVMe slots
Three E1.S slots support E1.S NVMe PCIe SSDs and include adapters for M.2 2280 NVMe PCIe SSDs.
Dual 2.5GbE
Two 2.5GbE ports support 2.5G, 1G, 100M and 10M network speeds.
Optional 10GbE
The supplied specification lists optional 10GbE through the QXG-ES10G1T.
QuTS hero data protection
The supplied overview identifies ZFS-based QuTS hero, data-integrity features and WORM protection for data immutability.
Who is the QNAP TS-h765eU-8G best for?
A strong choice for
- Space-constrained rack or cabinet installations
- Small-business shared storage
- QuTS hero and ZFS-based data protection
- Deployments needing SATA bays plus NVMe expansion
- Networks using dual 2.5GbE connectivity
Consider another model if you need
- More than four 3.5-inch SATA bays in the base chassis
- A tower rather than rackmount form factor
- More than 16 GB maximum memory
- Built-in 10GbE without an optional module
