# HP FX700 4TB: fast QLC storage at bulk capacity (2026)

The HP FX700 4TB combines the QLC line's full rated speed with the largest capacity and a 1,600 TBW endurance rating, all under a genuine 5-year warranty.

Quick answer: The HP FX700 4TB suits content creators, media archivists, and gamers with large libraries who want bulk capacity at genuinely fast rated speeds without paying TLC-drive prices. It's a weaker choice for professionals doing constant large sustained writes at the highest end, where a TLC-based rival like the Samsung 990 EVO Plus holds sequential write speed more consistently past its own cache limit. Buyers who want a more widely available alternative at a similar QLC price point should consider the Crucial P3 Plus 4TB. Overall, the FX700 4TB carries the line's fastest-QLC reputation forward with genuinely scaled endurance and a strong warranty to match.

## Performance

HP rates the FX700 4TB at up to 7,200 MB/s sequential reads and 6,200 MB/s sequential writes over PCIe 4.0 x4, matching the 1TB and 2TB capacities. The official datasheet lists random performance at 1,000,000 read IOPS and 820,000 write IOPS - the highest write-IOPS figure anywhere in the FX700 line, consistent with more NAND dies operating in parallel at this capacity.

QLC NAND is typically the weak point in a drive's sustained write performance, since it leans harder on its SLC write cache than TLC does. At 4 TB the FX700 has the largest absolute cache headroom in the line, so it takes a bigger sustained transfer to exhaust it before write speeds drop toward the native QLC ceiling. For large game libraries, media archives, and content-creation workflows that mix big files with everyday responsiveness, the FX700 4TB is one of the stronger QLC options available at this capacity, according to independent reviewers.

## Endurance, TBW & Warranty

HP rates the FX700 4TB at 1,600 TBW of total write endurance, backed by a 5-year limited warranty according to the official specification sheet. At a typical 20-50 GB of writes per day, that endurance budget lasts roughly 88 to 219 years before hitting the rated limit, far beyond any realistic ownership period, so endurance is effectively a non-issue at this capacity despite QLC's lower per-cell durability than TLC. The MTBF rating is 2,000,000 hours, a statistical reliability figure describing failure rates across a large population of drives rather than a promise for any individual unit.

The 5-year warranty term matches the rest of the FX700 line and is a genuine strength for a high-capacity QLC drive, especially paired with the 4TB model's properly-scaled endurance rating.

## Pros and Cons

**Pros:**

- 7,200 MB/s sequential reads on PCIe 4.0
- 1,600 TBW endurance, the highest in the FX700 line
- 820,000 write IOPS, the fastest write-IOPS in the line
- 5-year manufacturer warranty
- Single-sided design with included graphene thermal pad
**Cons:**

- QLC NAND has lower per-cell endurance than TLC
- DRAM-less design relies on Host Memory Buffer
- Highest power draw in the FX700 line at this capacity
- Sustained writes past the SLC cache trail TLC rivals


## Verdict

The HP FX700 4TB suits content creators, media archivists, and gamers with large libraries who want bulk capacity at genuinely fast rated speeds without paying TLC-drive prices. It's a weaker choice for professionals doing constant large sustained writes at the highest end, where a TLC-based rival like the Samsung 990 EVO Plus holds sequential write speed more consistently past its own cache limit. Buyers who want a more widely available alternative at a similar QLC price point should consider the Crucial P3 Plus 4TB.

## Frequently Asked Questions

### Is the HP FX700 4TB good for gaming?

Yes - it shares the FX700 line's strong random IOPS performance, the same lineup TweakTown called the fastest QLC it had tested, and 4 TB is enough for a very large modern game library. Normal gaming use rarely pushes past its SLC write cache, making it a strong pick for a primary gaming and storage drive combined.

### Is the HP FX700 4TB compatible with the PS5?

Yes - HP explicitly markets the FX700 for PS5 use, and its 7,200 MB/s rated sequential read comfortably clears Sony's suggested 5,500 MB/s minimum for expansion storage. Its single-sided M.2 2280 form factor with an included thermal pad fits the console's internal slot without clearance issues, and 4 TB is more capacity than most PS5 owners will need.

### Does the HP FX700 4TB have a DRAM cache?

No, the FX700 is a DRAM-less design that relies on Host Memory Buffer and an SLC write cache instead of a dedicated DRAM chip. At 4 TB the cache has the most absolute headroom in the line, and independent testing found the drive delivers unusually strong random IOPS for a QLC-based design.

### What is the TBW endurance and warranty of the HP FX700 4TB?

HP rates the 4TB FX700 at 1,600 TBW (terabytes written), the highest in the line, backed by a 5-year limited warranty. At a typical 20-50 GB of writes per day, that endurance budget lasts roughly 88 to 219 years before reaching the rated limit, making endurance essentially a non-issue at this capacity.

### Does the HP FX700 4TB need a heatsink?

HP already includes a 0.5mm graphene thermal pad on the drive itself, which is enough for laptops, the PS5, and typical desktop use. Given this capacity's higher power draw under sustained load, desktop users running heavy write workloads may see a more noticeable benefit from an additional motherboard M.2 heatsink than on smaller FX700 capacities.

### How does the HP FX700 4TB compare to the Crucial P3 Plus 4TB?

Both are DRAM-less, QLC-based PCIe 4.0 drives at bulk capacity, but the FX700 rates higher for sequential reads and random IOPS, and comes from the line TweakTown specifically called the fastest QLC it had tested. The Crucial P3 Plus has wider availability at major Western retailers and a longer independent track record, while the FX700's endurance rating and 5-year warranty are at least as strong.

### Is 4TB of QLC storage reliable enough for long-term use?

Yes for mainstream use - the FX700 4TB's 1,600 TBW rating and 5-year warranty are both properly scaled for the capacity, and at a realistic 20-50 GB of daily writes the endurance budget lasts far longer than most people keep a drive. QLC's main trade-off is sustained write consistency during very large transfers, not long-term reliability under normal use.
