Compact four-bay NAS for home cloud storage

The Qnap TS-433-4G-US is a diskless desktop NAS with four SATA drive bays, an ARM Cortex-A55 quad-core processor at 2.0GHz and 4GB of DDR4 memory. It runs QTS 5.0.1 and provides one 2.5GbE port, one 1GbE port, one USB 3.2 Gen 1 port and two USB 2.0 ports for backup or expansion. The unit includes a 90W power adapter and supports RAID 0, 1, 5, 6, 10, JBOD and single-drive modes.

Households wanting centralised media and backup

Families and home-office users who need a private cloud for photos, videos and documents will appreciate the built-in NPU for AI face recognition, snapshot protection and myQNAPcloud remote access. The 4GB memory is soldered and cannot be upgraded, so buyers who anticipate heavier virtualisation or database workloads should look elsewhere. The two Ethernet ports limit link aggregation to 2.5GbE and 1GbE speeds.

Four SATA bays with 88TB maximum capacity

The chassis accepts four 3.5-inch or 2.5-inch SATA hard drives or SSDs, delivering up to 88TB of raw storage when populated with the largest supported drives. This bay count and capacity ceiling determine whether the TS-433-4G-US can hold your current dataset and planned growth without requiring a larger enclosure.

Questions sur cet article

What size drives fit in the four bays of the TS-433-4G-US?

Each bay accepts 3.5-inch SATA hard drives, 2.5-inch SATA hard drives or 2.5-inch SATA SSDs up to the 88TB total capacity limit.

How do I install drives in the TS-433-4G-US and what step is often missed?

Slide each drive into a tray, secure it with the supplied screws, insert the tray until it clicks, then create a RAID volume in QTS 5.0.1 before storing data — skipping the volume creation is the common error.

What components may need replacement during the life of the TS-433-4G-US?

The 90W 12VDC power adapter and any installed 3.5-inch or 2.5-inch SATA drives are the field-replaceable parts; the 4GB DDR4 memory is soldered and not upgradeable.
