HP FX700 4TB: fast QLC storage at bulk capacity (2026)
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.
Read: 7200 MB/s Write: 6200 MB/s Endurance: 1600 TBW Warranty: 5 years Interface: M.2 4.0 x 4
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.
Controller & Memory
HP pairs a Maxio MAP1602A-F3C four-channel controller with YMTC's 232-layer QLC NAND on the FX700, skipping a dedicated DRAM chip but including a 0.5mm graphene thermal pad in the box. It connects over PCIe 4.0 x4 with NVMe 2.0 in a single-sided M.2 2280 form factor, and HP's own materials pitch it toward content creators as well as gamers at this larger capacity.
At 4 TB, the FX700 hits the same 7,200/6,200 MB/s sequential ratings as the 1TB and 2TB models - only the 512GB capacity runs slower - while endurance scales all the way up to 1,600 TBW, the top of a properly-scaling curve that starts at 200 TBW on the 512GB model. This is the same drive family TweakTown specifically praised as the fastest QLC SSD it had tested, at its largest available capacity.
Its single-sided PCB and included thermal pad make the FX700 4TB a strong fit for laptops and the PS5, which HP explicitly markets it for as external expansion storage. At this capacity it competes with other high-capacity budget-flagship drives like the Crucial P3 Plus 4TB and Samsung 990 EVO Plus 4TB, both of which are more widely stocked at major Western retailers but don't clearly beat it on endurance.

FX700 Performance & Benchmarks
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.

- HP FX700 4 TB (this drive): 7,200 MB/s read, 6,200 MB/s write
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.

Verdict: Is the FX700 Worth It in 2026?
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.
