Why Choose EvoSSD
The Industry Standard for SATA Upgrades
The Samsung 870 EVO 4TB is the definitive choice for users looking to max out their storage without moving to a new NVMe-based system. Whether you are upgrading an older Dell Inspiron, a custom-built gaming desktop, or a creative workstation, this 2.5-inch drive delivers the maximum saturation of the SATA III interface. It provides a transformative experience, reducing boot times from minutes to seconds and making applications feel snappy and responsive.
Unmatched Reliability and Endurance
With 4TB of space, this drive is built for the long haul. It features Samsung's 6th-generation V-NAND and a refined MKX controller, ensuring stable performance even under heavy workloads. For UK creators handling large 4K video files or gamers with massive Steam libraries, the 2,400 TBW (Terabytes Written) endurance rating means this drive will likely outlast the computer you install it in.
Simple Installation for Any PC
One of the greatest strengths of the 870 EVO is its 'plug and play' nature for SATA-based systems. It uses the standard 7mm 2.5-inch form factor, fitting perfectly into laptop drive bays and desktop mounting brackets. Compatible with Windows, macOS, and Linux, it is the most straightforward way to gain massive storage capacity without worrying about M.2 slot availability or PCIe lane configurations.

Customer Reviews
Transformed my 2015 iMac. The 4TB capacity means I finally have enough room for my entire Lightroom library internally. The speed difference over the old mechanical drive is night and day.
Bought this for my gaming rig to replace a noisy 4TB HDD. It's completely silent, and my games load almost instantly now. Great service from EvoSSD, arrived next day.
Perfect for my NAS setup. The high TBW rating gives me confidence that my data is safe for years to come. Best price I found in the UK for a genuine 4TB EVO.
Solid performance and huge space. Installation was easy in my Dell Latitude. Only 4 stars because the price is quite a jump from the 2TB version, but worth it for the convenience.
I was worried about compatibility with an older desktop, but it worked straight out of the box. Samsung Magician software made the transfer from my old 500GB drive seamless.
Great drive, very reliable. It's limited by the SATA interface so don't expect NVMe speeds, but for an older laptop upgrade, you can't do better than this capacity.
The best upgrade I've ever made. My laptop feels brand new and I never have to worry about 'disk full' warnings ever again. 4TB is a game changer.
