- Some users report the absence of mounting hardware or data cables in the package, requiring separate purchases.
- While generally reliable, some users have reported issues with early failures, though a firmware update reportedly addressed some of these.
- Can be priced higher than some competing SATA SSDs, and sometimes comparable to entry-level NVMe drives.
Dimension Scores
Achieves near-maximum sequential read (560 MB/s) and write (530 MB/s) speeds for the SATA III interface, but is limited by the interface compared to NVMe.
Backed by a 5-year limited warranty and a 600 TBW endurance rating for the 1TB model, indicating high durability for a SATA SSD.
1TB is a common and practical capacity for a primary boot drive or secondary storage, balancing cost and space for most users.
The 2.5-inch SATA form factor is widely compatible with older laptops, desktops, and various host systems, including NAS and video recording devices.
Best For
- Revitalizing older laptops or desktop PCs still using traditional hard disk drives.
- Systems with only SATA III ports available for storage expansion.
- Boot drives for general computing and application loading.
- Users needing a reliable, high-capacity 2.5-inch drive for data storage.
Not Recommended For
- New PC builds with M.2 NVMe slots, which offer significantly faster performance.
- Users requiring the absolute fastest data transfer speeds for intensive video editing or large file transfers.
- Budget-constrained buyers who can find cheaper SATA alternatives for basic storage.
Watch Out For
- No mounting hardware or SATA data cable included in the box, meaning you might need to buy these separately for installation.
- Some users experienced 'incorrect function' errors or inability to initialize the drive, requiring returns.
- The price point can be a sticking point; some Reddit users noted it was priced similarly to 1TB NVMe drives at certain times, making it less competitive on a performance-per-dollar basis.

What Buyers Say
Many users upgrading from traditional hard drives report a dramatic increase in system responsiveness and speed, with boot times cut significantly. The included migration software is frequently praised for making the transition easy, even for less tech-savvy individuals. While performance is capped by the SATA interface, it's consistently noted as a top performer within that limitation. Some complaints revolve around the lack of included mounting hardware or cables, and a few users have encountered issues with drive initialization or early failures, though these seem less common now.
“Dude, my old laptop was crawling, like, seriously slow. Popped this in, and it's like a whole new machine, boots up in seconds now, but seriously, why no screws in the box?!”
Common Praise
- System boots and applications load much faster than with an HDD.
- Migration software makes transferring the OS and files seamless and easy.
- Consistent read and write speeds, even under heavy workloads.
- Easy physical installation due to the standard 2.5-inch form factor.
- Samsung Magician software provides useful tools for drive management.
- Perceived as a significant upgrade for older machines.
Common Complaints
- Does not include mounting screws or SATA data cables, requiring separate purchase.
- Some reports of 'incorrect function' errors or drives not being recognized upon initial setup.
- Price can be higher than other SATA SSDs, sometimes nearing entry-level NVMe drives.
- Specific laptop models might have physical size compatibility issues.
Ownership Tips
- The performance boost over an HDD is immediately noticeable, making old systems feel current again.
- Samsung's Magician software is genuinely useful for monitoring drive health and optimizing performance over time.
- Even after months of heavy use, the drive maintains its speed without noticeable slowdowns.
- The 2.5-inch form factor means it's a direct swap for many laptop hard drives, simplifying upgrades.
- While fast for SATA, it won't keep up with modern NVMe drives in benchmarks, but for everyday tasks, the difference is often imperceptible.
Frequently Asked Questions
Is this SSD faster than a traditional hard drive?
Yes, it's significantly faster. Users report boot times dropping from 30 seconds to around 10 seconds after upgrading from an HDD. Sequential read/write speeds of 560/530 MB/s are many times faster than typical HDDs.
Does it come with software to transfer my old data?
Yes, Samsung provides renewed migration software to help you transfer your operating system and files from your old drive to the 870 EVO.
Will this fit in my laptop?
The 870 EVO uses a standard 2.5-inch form factor, which is compatible with most laptops and desktop PCs that support 2.5-inch SATA drives. However, some users have reported size compatibility problems with specific laptop models.
What is the warranty for this SSD?
It comes with a 5-year limited warranty, covering up to 600 TBW for the 1TB model.
Can I use this for gaming?
Yes, it's suitable for gaming, offering faster game loading times compared to HDDs. However, NVMe drives will offer even quicker load times if your system supports them.
Buying Guide
When looking at an SSD like this, you're primarily buying speed and responsiveness for your computer. Unlike old spinning hard drives, SSDs have no moving parts, which means they can access data almost instantly. This translates to faster boot times, quicker application loading, and snappier overall system performance. You're getting a significant upgrade if you're moving from an HDD, but it's important to understand the limits of the SATA interface.
Capacity (1TB)
This is how much data you can store. 1TB is enough for your operating system, many applications, and a good amount of files, photos, or games. Think of it like the size of your digital closet.
Interface (SATA III)
This is how the SSD connects to your computer. SATA III is the most common connection for older systems and offers speeds up to 600 MB/s. It's like the road your data travels on; SATA is a fast highway, but NVMe is a super-expressway.
Form Factor (2.5 Inches)
This refers to the physical size and shape of the drive. A 2.5-inch drive is the standard size for laptop hard drives and fits into specific bays in desktop PCs. It's like the physical package your data highway comes in.
Sequential Read/Write Speeds (560/530 MB/s)
These numbers tell you how fast the drive can read and write large, continuous files. Higher numbers mean faster transfers for things like copying big videos or loading large game levels. These speeds are near the maximum theoretical limit for the SATA III interface.
Alternatives
If you need faster speeds and your system supports it, look for M.2 NVMe SSDs with PCIe Gen3 or Gen4 interfaces. If you need a larger capacity at a lower price point and can tolerate slightly slower performance, consider QLC-based SATA SSDs.
