# Team Group MP44Q 4TB Review — QLC Density, Gen4 Speed (2026)

The Team Group MP44Q 4TB sells QLC density the honest way — 7,000 MB/s Gen4 reads, 2,048 TBW of endurance and serious headroom for game libraries.

Quick answer: The Team Group MP44Q 4TB is for the archive builder: a game vault, media library or PS5 expansion that wants 7,000 MB/s reads and 2,048 TBW of endurance at QLC pricing, with five years of coverage. Skip it for constant heavy writing — post-cache QLC throughput falls to hard-drive pace — and note Tom's Hardware's caution that TLC drives get compelling at 4 TB prices; the Crucial P310 4TB or a TLC sale might serve heavy users better. The Crucial P3 Plus 4TB is the closest QLC rival at a lower rated speed. As budget bulk storage with flagship-class endurance numbers, the 4 TB MP44Q makes a coherent and confident case.

## Performance

TeamGroup rates the MP44Q 4TB at 7,000 MB/s sequential reads and 5,900 MB/s writes — the same figures as every capacity in the range, and a rating that clears Sony's 5,500 MB/s PS5 guidance with room to spare. No random IOPS figure is published. In daily use, reads at this level mean game loads and file access with no perceptible penalty against costlier TLC drives; Tom's Hardware's testing of the 2 TB sibling found the platform outscoring TLC rivals including the Kingston NV3, TeamGroup's own MP44 and the WD Black SN770 in 3DMark and PCMark storage benchmarks.

The QLC trade-off matters more at 4 TB only because buyers here move bigger files. The dynamic pseudo-SLC cache absorbs bursts — roughly a quarter of the 2 TB model's capacity per Tom's Hardware's measurements, with writes of 5.75 GB/s sustained for 86 seconds before a drop to around 103 MB/s. A 4 TB drive scales that cache up, so the wall arrives later but the post-cache pace is similar. Media archivists and game-library builders rarely hit it; editors shuffling terabytes of footage daily should buy TLC. Where the platform shines for this capacity's audience is efficiency and thermals: low power draw, a 56-degree Celsius peak in write testing, and a graphene label that adds under a millimeter of height.

## Endurance, TBW & Warranty

Team Group backs the MP44Q 4TB with a 5-year limited warranty rated at 2,048 TBW of writes — the product page rounds the figure to 2,000 TBW — whichever limit arrives first. That is endurance usually reserved for flagship TLC drives, and it translates to roughly 280 years at a steady 20 GB of daily writes, so the warranty term is the practical ceiling. The 1 TB and 2 TB models carry 512 TBW and 1,024 TBW on identical terms, and an 8 TB flagship tops the range at 4,000 TBW. The rated MTBF of 1.6 million hours is a fleet-wide population statistic, not a per-drive promise, but it ranks near the top of the consumer tier. Claims run through TeamGroup's regional service network with proof-of-purchase.

## Pros and Cons

**Pros:**

- Rated 7,000 MB/s reads and 5,900 MB/s writes
- 2,048 TBW endurance — flagship-drive territory
- 5-year warranty at a QLC price point
- Low power draw confirmed in Tom's Hardware testing
- Single-sided 3.7 mm PCB with graphene label
**Cons:**

- Post-cache writes drop to roughly 100 MB/s
- No DRAM on the PCB — Host Memory Buffer only
- TLC alternatives get compelling at 4 TB pricing
- Random IOPS figures not published


## Verdict

The Team Group MP44Q 4TB is for the archive builder: a game vault, media library or PS5 expansion that wants 7,000 MB/s reads and 2,048 TBW of endurance at QLC pricing, with five years of coverage. Skip it for constant heavy writing — post-cache QLC throughput falls to hard-drive pace — and note Tom's Hardware's caution that TLC drives get compelling at 4 TB prices; the Crucial P310 4TB or a TLC sale might serve heavy users better. The Crucial P3 Plus 4TB is the closest QLC rival at a lower rated speed. As budget bulk storage with flagship-class endurance numbers, the 4 TB MP44Q makes a coherent and confident case.

## Frequently Asked Questions

### Is the Team Group MP44Q 4TB compatible with the PS5?

Measured against Sony's published requirements — PCIe 4.0 NVMe, 5,500 MB/s or faster reads recommended, and dimensions no larger than 110 x 25 x 11.25 mm with heatsink — the MP44Q 4TB passes on every point. The 7,000 MB/s rating beats the speed guidance comfortably, the graphene label adds under a millimeter over the 3.7 mm PCB, and TechPowerUp marks the family PS5-compatible. Four terabytes suits console owners who keep a large installed library, since PS5 games occupy 50 to 150 GB each. QLC's slower post-cache writes affect installation tail times more than gameplay, but for a budget PS5 library expansion the capacity-per-dollar math is the main attraction.

### Is the Team Group MP44Q 4TB good for gaming?

For loading games, absolutely. The 7,000 MB/s sequential read rating sits at the top of PCIe 4.0, so levels load with no perceptible penalty against more expensive drives, and Tom's Hardware's review of the 2 TB sibling found the platform outscoring TLC drives like the WD Black SN770 and Kingston NV3 in 3DMark and PCMark storage benchmarks. Four terabytes holds roughly 40 to 60 large modern games alongside an operating system. The write-side caveat is QLC's post-cache behavior: massive install batches eventually drop into slow writes while data folds into dense cells. For playing rather than constantly shuffling a library, the 4 TB MP44Q is a strong budget game vault.

### What is the TBW endurance of the Team Group MP44Q 4TB?

The 4 TB model is rated at 2,048 TBW under the 5-year limited warranty, whichever comes first — TeamGroup's product page rounds the figure to 2,000 TBW, and TechPowerUp's database entry for this exact capacity corroborates the 2048 TBW rating. Endurance doubles with each capacity step in the family: 512 TBW at 1 TB and 1,024 TBW at 2 TB. At a steady 20 GB of daily writes, the 4 TB budget would take roughly 280 years to exhaust, so the warranty term is the realistic limit. QLC's lower per-cell program/erase tolerance is already accounted for in the rated figure, and the warranty length matches premium TLC drives.

### Does the Team Group MP44Q have a DRAM cache?

No. The MP44Q is a DRAM-less design built on Maxio's MAP1602 controller, which relies on the NVMe Host Memory Buffer feature to store the flash translation table in system RAM. A dynamic pseudo-SLC cache carved from the QLC NAND absorbs burst writes on top of that. For boot duty, gaming and general desktop use, HMB responsiveness comes close to DRAM-equipped drives while cutting cost and power draw — the latter confirmed in Tom's Hardware's efficiency testing. On the 4 TB model the dynamic cache scales with capacity, delaying the post-cache slowdown during large transfers. Constant multi-hundred-gigabyte write sessions remain the workload where a DRAM-equipped TLC drive justifies its premium.

### Team Group MP44Q 4TB or Crucial P3 Plus 4TB for bulk storage?

Both are QLC Gen4 drives aimed at the same cheap-terabytes buyer, and the MP44Q holds the rated-speed advantage: 7,000/5,900 MB/s against the P3 Plus 4TB's 5,000 MB/s read ceiling. Both are DRAM-less HMB designs that share the post-cache write slowdown, so neither suits constant heavy transfers. The MP44Q extends to 8 TB where Crucial stops, and its 2,048 TBW endurance rating at 4 TB is generous for the QLC class. Crucial counters with a long retail track record and often sharper shelf pricing. Choose the TeamGroup for rated speed and endurance; choose Crucial when the price gap on the day decides it.

### Is a 4TB QLC drive a bad idea for video editing or heavy writing?

For editing projects that involve frequent multi-hundred-gigabyte transfers, yes — the capacity should not be mistaken for sustained-write capability. Once the MP44Q's pseudo-SLC cache exhausts, writes settle to roughly 100 MB/s while data folds back into QLC cells, a pace Tom's Hardware measured on the 2 TB sibling. Cache recovery is not instant, so back-to-back large exports queue behind the folding process. Reading archives, loading games and holding projects remain excellent uses, and the 2,048 TBW endurance rating means the flash itself will outlast the warranty by decades. If daily sustained writes are the workload, a TLC drive such as the WD Black SN770 or Crucial T500 is the correct tool.
