6 Best Alternatives to the Samsung 870 QVO SATA III (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
Finding practical samsung 870 qvo sata iii alternatives depends on your specific storage needs and hardware configuration. The Samsung 870 QVO excels at high-capacity performance, offering up to 8TB of storage space, 2,880 TBW endurance on its largest model, and sequential speeds up to 560 MB/s read and 530 MB/s write. These specifications make it an effective 2.5-inch SATA III drive for desktop and laptop setups requiring substantial data storage.
You might want an alternative if your system needs a smaller capacity, such as 256GB, 512GB, or 1TB. You may also prefer solid-state drives using 3D TLC NAND flash memory or options featuring SLC cache technology from other brands. We selected these 6 alternatives because their primary specifications overlap with the original Samsung drive. Every option shares the standard 2.5-inch form factor, connects via SATA III, and delivers sequential speeds between 500 MB/s and 560 MB/s for your upgrade in 2026.
Our top pick: Samsung 870 QVO 8TB 2.5-Inch SATA SSD.
How Each Alternative Compares
Addlink S20 1TB 2.5-Inch SATA SSD
The Addlink S20 offers 1TB of 3D NAND storage with SLC caching in a standard 7mm enclosure. Compared to the 8TB Samsung 870 QVO, you trade away 7TB of storage volume and peak transfer rates, as the S20 reaches up to 500 MB/s read speeds versus Samsung's 560 MB/s sequential read and 530 MB/s sequential write performance. However, the S20 provides dedicated SLC caching for handling everyday file transfers in standard 2.5-inch bays. You should pick the Addlink S20 if you need a straightforward 1TB drive replacement for an older laptop or gaming console hard drive, where basic SATA capability matters more than maximum archive capacity.
TEAMGROUP GX2 512GB SATA III 2.5-Inch SSD
The TEAMGROUP GX2 features 3D TLC NAND flash and integrated DevSleep power efficiency in a 512GB capacity. Compared to the Samsung 870 QVO, the GX2 relies on TLC flash rather than Samsung's 4-bit QLC architecture. You give up the massive 8TB storage pool and top-tier 560 MB/s sequential read speeds, as the GX2 reaches 530 MB/s read performance. It also lacks the extensive 2,880 TBW endurance rating provided by the 8TB Samsung drive. You should select the TEAMGROUP GX2 if you are servicing a legacy laptop or desktop that only needs a focused 512GB upgrade with power-saving features for routine daily computing.
Timetec 1TB 2.5-Inch SATA III SSD
The Timetec 1TB SATA SSD pairs 3D NAND with an SLC cache to deliver sequential speeds up to 550 MB/s. In contrast to the Samsung 870 QVO, you lose 7TB of total space and fall just short of Samsung's 560 MB/s maximum read speed. You also miss out on Samsung's refined ECC algorithm and its 2,880 TBW endurance specification. In return, the Timetec provides SLC cache acceleration for general write tasks in a standard 2.5-inch footprint. You should choose this Timetec drive if you want an entry-level 1TB storage drive for routine system maintenance or older PC refresh projects instead of high-capacity archiving.
Fanxiang 1TB 2.5-Inch SATA TLC SSD
The Fanxiang 1TB SSD provides 3D TLC NAND flash memory inside a standard 2.5-inch SATA enclosure. It runs at sequential speeds up to 520 MB/s, which falls behind the Samsung 870 QVO's 560 MB/s read and 530 MB/s write limits. Opting for this drive means sacrificing 7TB of capacity and the heavy-duty 2,880 TBW endurance rating of the 8TB QVO. However, the Fanxiang incorporates TLC cells rather than 2nd generation QLC flash. Pick the Fanxiang 1TB if you prefer the standard characteristics of TLC flash for an everyday hard drive replacement and do not require massive multi-terabyte data storage.
Fikwot 1TB TLC SATA III SSD
The Fikwot 1TB SSD matches the Samsung 870 QVO on peak sequential read capability at up to 560 MB/s while utilizing 3D TLC flash. Choosing the Fikwot gives you TLC cell architecture for your daily transfers, but you surrender 7TB of available room compared to Samsung's 8TB ceiling. You also forgo Samsung's 2,880 TBW endurance baseline and specialized ECC controller algorithm. The Fikwot fits standard 2.5-inch drive bays across laptops and desktops. You should choose the Fikwot 1TB drive if you want matching 560 MB/s SATA interface read speeds and TLC NAND flash for everyday general computing without needing excessive storage capacity.
KingSpec 256GB 2.5-Inch SATA III SSD
The KingSpec 256GB SSD provides an entry-tier 3D NAND configuration for systems with minimal storage demands. Compared to the Samsung 870 QVO, you trade off nearly all raw capacity, dropping from 8TB down to 256GB. You also leave behind Samsung's 560 MB/s sequential read rates, 530 MB/s write limits, and 2,880 TBW rating. However, the 2.5-inch KingSpec drive installs into standard SATA bays without adding unneeded volume. Choose the KingSpec 256GB if you only need a small boot drive to hold an operating system or basic applications, rather than a massive storage repository for large multimedia libraries or extensive backup archives.

Frequently asked questions
Which Samsung 870 QVO alternative offers the fastest sequential read speed?
The Fikwot 1TB SSD offers the highest sequential read speed among the alternatives, reaching up to 560MB/s. This drive uses 3D TLC flash storage in a standard 2.5-inch form factor. Other options like the Timetec 1TB reach up to 550MB/s, while the TEAMGROUP GX2 achieves 530MB/s. You get standard SATA III interface bandwidth across all these choices.
Can you use these 2.5-inch SATA SSD alternatives in gaming consoles?
Yes, you can install compatible 2.5-inch SATA III SSDs into consoles that support standard 2.5-inch internal drives. For example, the Addlink S20 1TB specifically suits PS4 console hard drive replacements alongside laptop setups. Because it features a 7mm enclosure, SLC caching, and standard SATA connections, it drops directly into standard drive bays without needing custom adapters.
Which alternatives use 3D TLC NAND flash memory instead of QLC?
The TEAMGROUP GX2, Fanxiang S101, and Fikwot drives use 3D TLC NAND flash memory. TLC flash stores three bits of data per cell. The TEAMGROUP GX2 provides 512GB of TLC storage, while the Fanxiang and Fikwot models provide 1TB each. These configurations deliver read speeds between 520MB/s and 560MB/s for everyday desktop and laptop drive upgrades.
What is the smallest capacity alternative available on this list?
The KingSpec 2.5-Inch SATA III SSD is the smallest capacity drive on the list at 256GB. It utilizes 3D NAND flash memory and fits standard 2.5-inch drive bays in laptops and desktops. This capacity works well if you only need a basic boot drive for routine system maintenance rather than storing large media libraries.
Do any of these SATA III SSD alternatives include SLC caching?
Yes, both the Addlink S20 1TB and the Timetec 1TB SSDs specify SLC cache support. SLC caching allocates a portion of the 3D NAND memory to act as single-level cell flash. This mechanism helps manage temporary write bursts. Both drives share the 2.5-inch form factor and SATA III interface, providing practical options for desktop and laptop drive upgrades.
Which alternative includes DevSleep support for power efficiency?
The TEAMGROUP GX2 512GB SSD features DevSleep efficiency for power management. DevSleep allows compatible host devices to place the SATA drive into a low-power standby state when idle. This makes the 512GB GX2 a practical pick for legacy laptop upgrades. It also features 3D TLC NAND and delivers sequential read speeds up to 530 MB/s.
Are all 6 alternatives compatible with both laptops and desktops?
Yes, all 6 alternatives on this list support both laptop and desktop systems. Every listed drive features the 2.5-inch form factor and utilizes the SATA III interface. As long as your laptop or desktop contains a standard 2.5-inch drive bay and a SATA connection, you can install any of these drives directly as system storage.
