The largest SSD and hard drive of 2025

This 2-bay NAS can accommodate up to 60TB of hard drive storage and supports up to 50 user accounts

This tiny NAS can store up to 32TB of super-fast SSD data and even comes with a VPN server and a 4K HDMI port

This absurdly powerful NAS uses a Ryzen AI 9 CPU paired with up to 96GB ECC RAM, OCuLink, and has its own MinisCloud OS

TerraMaster F4 NAS SSD review

Is this the fastest external SSD ever? Terramaster’s D1 can reach almost 4GB/s in write speeds when paired with a Samsung 990 Pro

This NAS has an integrated UPS and can accommodate more than 180TB of storage, as well as a memory card – but I wonder how much it will actually cost

Rare AMD CPU powers this just-announced NAS offering, not only 2 USB4 ports but also one OCuLink connector – I’d love to use it as a mini PC

Intel Celeron N5095 drives TerraMaster’s fastest consumer-grade NAS yet
TerraMaster F4-425’s four-bay design allows staggering 120TB capacity for growing media libraries
Hardware-level 4K H.265 decoding supports smooth Plex and Emby streaming

TerraMaster has introduced the F4-425, a four-bay network-attached storage device that swaps older ARM chips for an Intel Celeron N5095 quad-core CPU.

The company promotes this as its “fastest” Celeron-based NAS so far, claiming a 40% performance increase over earlier ARM-based systems.
It targets home users but borrows traits usually found in higher-end storage units, such as 4GB of DDR4 memory, a 2.5GbE network port, and the ability to handle 4K video encoding and decoding.

Massive storage and the controversial TRAID technology
The shift to Intel x86 architecture positions it closer to entry-level enterprise devices while still being marketed as a consumer solution.

The F4-425 supports up to 120TB through four 30TB drives, giving households and small creative teams plenty of headroom.
TerraMaster’s new TRAID feature is the most talked-about addition, promising up to 30% greater storage efficiency than traditional RAID without sacrificing redundancy.
While that sounds appealing, the claim warrants scrutiny, as efficiency gains often involve trade-offs in resilience or recovery speed.

The TNAS Mobile app allows initial setup without a PC and enables local or remote synchronization for smartphone backups.
TerraSync adds millisecond-level file syncing and a 32-version recovery system, while the Push-Lock tool-free design claims to install drives in ten seconds.
Low noise levels of 21dB(A) are promoted as another home-friendly feature.
The F4-425 is listed at £369.99 in the UK and $369.99 in the US, with a temporary 10% discount.
This pricing makes it attractive for home users or small studios.
While Intel’s N5095 chip is faster than many ARM options, real-world performance depends on network conditions, drive quality, and firmware maturity.
