What Our Customers Say
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.
Installation Guide
- Back up your existing data using a cloud service or external drive.
- Power down your PC or laptop and remove the battery if applicable.
- Locate the 2.5-inch drive bay and remove the old hard drive or SSD.
- Connect the 870 EVO 4TB to the SATA data and power cables (or slide into the laptop slot).
- Secure the drive with screws, restart your machine, and use Samsung Magician software to clone your data or perform a fresh OS install.
Based in the UK, EvoSSD was founded on the principle that a great computer shouldn't be replaced just because the storage is full or slow. We recognised that many British professionals, gamers, and creatives still rely on dependable hardware that uses the 2.5-inch SATA standard, yet find themselves underserved by the shift towards NVMe-only focuses.
Our mission is to provide the easiest high-capacity internal upgrade path available. By focusing on the 4TB 2.5-inch SATA segment, we offer a massive storage boost that fits seamlessly into older laptops and desktops without the need for expensive adapters or entirely new systems.
We pride ourselves on technical transparency and reliability. Every drive we supply undergoes rigorous testing to ensure it meets the endurance demands of modern workflows, from 4K video editing to extensive gaming libraries, all while maintaining the straightforward compatibility of the SATA III interface.
Why UK Customers Love Us
Our products are designed and supported in the UK, ensuring superior quality and fast tracked delivery from our British warehouse. We offer free UK delivery on all orders, eco-friendly packaging to reduce carbon footprint, and warm, direct customer service. Every order is backed by a generous 30-day returns policy under the UK Consumer Rights Act 2015 — you are always protected.
