Manufacturer description
The TEAMGROUP QX 4TB is a 2.5-inch SATA III solid state drive built for people who need bulk capacity without stepping up to NVMe pricing. It uses 3D NAND QLC flash with Smart Dual Cache and SLC caching, delivering read speeds up to 500 MB/s and writes up to 460 MB/s — enough to saturate the SATA III interface and leave any mechanical hard drive behind on boot times, game loading, and large library access. At 4TB, this TEAMGROUP drive is aimed at Steam libraries, photo and video archives, and laptop upgrades where a single 2.5-inch bay has to hold everything. Endurance is rated at 800TBW…
SpecPicks Verdict
SpecPicks scored TEAMGROUP QX 4TB 3D NAND QLC 2.5 Inch SATA III Internal Solid State… using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. TEAMGROUP's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How fast is the TEAMGROUP QX 4TB SSD?
It reads at up to 500 MB/s and writes at up to 460 MB/s, which is the practical ceiling of the SATA III interface. Smart Dual Cache and SLC caching help sustain those speeds during bursts.
Will this SSD fit in my laptop?
It is a standard 2.5-inch SATA III drive, so it fits any laptop or desktop with a 2.5-inch SATA bay. TEAMGROUP advises confirming your motherboard, processor, and BIOS support the drive before purchasing.
What is the warranty on the TEAMGROUP QX 4TB?
TEAMGROUP covers it with a 3-year or TBW limited warranty, whichever comes first, plus free technical support through the official TEAMGROUP website. TBW is defined per the JEDEC standard.
How much data can I write to it before it wears out?
The QX 4TB is rated for 800TBW — 800 terabytes written — measured under the JEDEC standard. That is roughly 200 full drive writes, well beyond typical consumer use over the warranty period.
Is QLC NAND a problem for a drive this size?
QLC stores more bits per cell, which is how TEAMGROUP reaches 4TB at this price, but sustained writes slow after the SLC cache fills. For game libraries, media archives, and general storage that read far more than they write, it is a reasonable trade.
