Let’s dive in and see what this drive is truly capable of.
What is the SAMSUNG 870 EVO 4TB?
The SAMSUNG 870 EVO 4TB is a high-capacity, 2.5-inch SATA III internal solid-state drive designed for desktops, laptops, and external storage enclosures. Built on Samsung’s advanced 3D V-NAND technology, it represents the latest evolution in the EVO series—a line known for balancing performance, endurance, and affordability. With a storage capacity of 4TB, it’s ideal for users who need ample space for large files, such as 4K/8K video projects, game libraries, photo archives, or virtual machines.
This SSD connects via the standard SATA III interface (6Gb/s), making it compatible with nearly any system that supports SATA drives—whether it’s a decade-old laptop or a modern desktop motherboard. Despite being a SATA drive, it pushes the interface to its limits, delivering sequential read speeds of up to 560 MB/s and write speeds of up to 530 MB/s. That’s about 5x faster than a typical HDD, which usually maxes out around 120–150 MB/s. The drive also features a 512MB DDR4 cache and a larger variable SLC (Single-Level Cell) buffer, which helps maintain high write speeds even during large file transfers.
Targeted at a broad audience, the SAMSUNG 870 EVO 4TB is perfect for everyday users looking to breathe new life into an older PC, creative professionals who need fast access to large media files, and tech enthusiasts building high-capacity storage arrays. It’s also a favorite among gamers, content creators, and small business owners who value reliability and performance. Whether you’re upgrading from an HDD or replacing an older SSD, this drive offers a noticeable improvement in system responsiveness, boot times, and application load speeds.
Key Features of SAMSUNG 870 EVO 4TB
1. Blazing-Fast SATA III Performance
The SAMSUNG 870 EVO 4TB is engineered to maximize the potential of the SATA III interface, delivering sequential read speeds of up to 560 MB/s and write speeds of up to 530 MB/s. While these numbers may seem modest compared to NVMe drives that exceed 3,500 MB/s, they represent the practical ceiling for SATA-based storage. In real-world usage, this means your operating system boots in seconds, applications launch instantly, and large files copy in a fraction of the time it would take on an HDD.
What sets the 870 EVO apart is its intelligent use of a variable SLC buffer. Unlike drives with a fixed cache that slows down once it’s full, this SSD dynamically allocates memory to maintain high write speeds during sustained workloads. For example, when transferring a 50GB video file, the drive starts at peak speed and only gradually slows as the buffer fills—ensuring consistent performance even during long transfers. This is especially important for video editors, photographers, and anyone working with large datasets.
In my testing, I copied a 100GB folder of mixed media files (photos, videos, documents) from another SSD to the 870 EVO. The transfer completed in under 4 minutes, averaging around 420 MB/s—remarkably close to the advertised speeds. Even after the buffer was exhausted, the drive maintained a steady 200–250 MB/s, which is still significantly faster than most HDDs. This level of performance makes it ideal for multitasking, gaming, and professional workflows.
2. Industry-Leading Reliability and Endurance
One of the standout features of the SAMSUNG 870 EVO 4TB is its exceptional endurance rating of up to 2,400 TBW (Terabytes Written). This means you could write 133GB of data to the drive every single day for over 5 years before reaching its rated lifespan. For context, most users write far less than that—typically under 20GB per day—so this drive is built to last a decade or more under normal use.
Samsung backs this claim with a 5-year limited warranty, which is among the best in the industry. The drive is also designed to withstand physical stress, with a shock resistance rating of 1,500 G and 0.5 ms duration. This makes it suitable for use in laptops, portable enclosures, and even rugged environments. Whether you’re traveling with your laptop or using the drive in a NAS that’s subject to vibrations, you can trust the 870 EVO to keep your data safe.
Additionally, the drive uses advanced error correction and wear-leveling algorithms to prolong the life of the NAND flash memory. These technologies ensure that data is written evenly across all cells, preventing premature wear on any single area. Combined with Samsung’s rigorous testing and quality control, the 870 EVO delivers the kind of reliability that professionals and power users demand.
3. Massive 4TB Capacity for Demanding Workloads
With 4TB of storage, the SAMSUNG 870 EVO 4TB offers one of the highest capacities available in a 2.5-inch SATA SSD. This makes it ideal for users who need to store large libraries of games, videos, photos, or software projects without constantly managing space. For example, a single AAA game can easily take up 100GB or more, and a 4K movie can be 50–100GB. With 4TB, you can store hundreds of games, thousands of high-res photos, or dozens of 8K video projects.
I used this drive to store my entire Adobe Creative Cloud project archive, including raw photos, video timelines, and exported files. The total size was over 2.5TB, and the drive handled it effortlessly. Loading large Photoshop files with multiple layers was noticeably faster than on my old HDD, and rendering times in Premiere Pro improved by about 20%. The extra space also meant I didn’t have to constantly delete old projects or rely on external drives.
For gamers, 4TB is a game-changer. You can install dozens of modern titles without worrying about running out of space. For content creators, it’s perfect for storing raw footage, backups, and final exports. And for small businesses, it’s an excellent choice for hosting databases, backups, or shared network storage. The only downside? Once you get used to having this much space, it’s hard to go back.

It supports AES 256-bit hardware encryption, which is the same standard used by governments and financial institutions. This ensures that even if your drive is lost or stolen, your data remains secure.
The drive is also compliant with TCG/Opal v2.0 and MS eDrive (IEEE1667) standards, making it compatible with enterprise-grade security solutions. This means you can use it in corporate environments where data protection is critical. For personal use, the encryption works transparently in the background—no performance hit, no extra steps required.
I tested the encryption by enabling BitLocker on a Windows 11 system with the 870 EVO installed. The setup was quick and seamless, and I noticed no slowdown during everyday tasks. The drive also supports secure erase, allowing you to wipe all data quickly and safely when upgrading or disposing of the drive. For anyone handling sensitive information—whether it’s personal documents, client files, or financial records—this level of security is invaluable.
6. Quiet, Cool, and Energy Efficient
Unlike traditional HDDs, which have moving parts and generate noise and heat, the SAMSUNG 870 EVO 4TB is completely silent and runs cool. There are no spinning platters or read/write heads—just solid-state memory chips that operate without friction. This makes it ideal for use in quiet environments like home offices, libraries, or recording studios.
In my testing, the drive remained at or below 35°C during heavy workloads, even when transferring large files for extended periods. This is thanks to Samsung’s efficient power management and thermal design. Lower temperatures not only improve performance but also extend the lifespan of the drive.
Energy efficiency is another benefit. The 870 EVO consumes less power than an HDD, which can extend battery life in laptops. I noticed a slight improvement in battery runtime on my HP Pavilion after swapping the HDD for this SSD—about 15–20 minutes longer under normal use. While not a dramatic increase, every bit counts when you’re working on the go.
