# HP FX900 Pro 1TB -- InnoGrit IG5236 PCIe 4.0 NVMe SSD Review (2026)

The HP FX900 Pro 1 TB is the capacity sweet spot in HP's flagship PCIe 4.0 SSD line, delivering near-gen4-ceiling throughput on the InnoGrit IG5236 controller.

Quick answer: The 1 TB FX900 Pro is the capacity to buy in the HP Gen4 lineup. It delivers near-maximum PCIe 4.0 read speeds, solid write throughput, and 600 TBW endurance sufficient for any consumer workload. The InnoGrit IG5236 is a proven alternative to the Phison E18. At competitive pricing, the FX900 Pro 1 TB is a strong contender against the Samsung 990 Pro 1 TB, WD Black SN850X 1 TB, and Kingston KC3000 1 TB. Compare pricing and choose the best-value option at the time of purchase.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 1 TB |
| Interface | M.2 4.0 x 4 |
| Controller | Innogrit IG5236 |
| Memory type | Micron TLC |
| DRAM cache | DDR4 |
| Sequential read | 7400 MB/s |
| Sequential write | 6400 MB/s |
| Random read IOPS | 1300000 |
| Random write IOPS | 1100000 |
| Endurance | 600 TBW |
| MTBF | 2000000 |
| Warranty | 5 years |

## Performance

The 1 TB FX900 Pro delivers 7,400/6,400 MB/s sequential reads and writes with up to 1,300,000/1,100,000 read/write IOPS. The IG5236 pseudo-SLC cache handles burst writes efficiently. Under sustained workloads, temperatures are competitive with other Gen4 flagships. Gaming load times are indistinguishable from any PCIe 4.0 drive.

## Endurance, TBW & Warranty

HP covers the FX900 Pro 1 TB with a five-year warranty limited by 600 TBW, equivalent to roughly 328 GB/day over five years. The 512 GB model carries 300 TBW, 2 TB 1,200 TBW, and 4 TB reaches 2,400 TBW.

## Pros and Cons

**Pros:**

- 7,400/6,400 MB/s -- near-full PCIe 4.0 ceiling
- InnoGrit IG5236 -- proven Gen4 controller
- Single-sided PCB -- fits thin laptops
- 600 TBW endurance with 5-year warranty
- PS5-compatible
**Cons:**

- Write speed marginally below 2TB model (6,400 vs 6,700 MB/s)
- Less brand recognition than Samsung or WD in the SSD space
- No factory heatsink option


## Verdict

The 1 TB FX900 Pro is the capacity to buy in the HP Gen4 lineup. It delivers near-maximum PCIe 4.0 read speeds, solid write throughput, and 600 TBW endurance sufficient for any consumer workload. The InnoGrit IG5236 is a proven alternative to the Phison E18. At competitive pricing, the FX900 Pro 1 TB is a strong contender against the Samsung 990 Pro 1 TB, WD Black SN850X 1 TB, and Kingston KC3000 1 TB. Compare pricing and choose the best-value option at the time of purchase.

## Frequently Asked Questions

### Is the 1TB FX900 Pro good for PS5?

Yes — 7,400 MB/s reads exceed the 5,500 MB/s minimum. The standard M.2 2280 form factor and single-sided PCB fit the PS5 expansion bay. Add a compatible heatsink since the drive ships bare.

### What is the TBW of the 1TB FX900 Pro?

Rated for 600 TBW over five years, equivalent to roughly 328 GB/day. The 2 TB carries 1,200 TBW.

### How does the InnoGrit IG5236 compare to the Phison E18?

Both are 8-channel PCIe 4.0 controllers delivering similar real-world performance. The E18 is more widely adopted (Corsair, Kingston, Seagate), while the IG5236 appears in HP, PNY, and ADATA drives. Peak throughput is comparable.

### Does it have DRAM?

Yes — the FX900 Pro includes DRAM cache for better random I/O performance compared to DRAM-less HMB designs.

### How does it compare to the Samsung 990 Pro 1TB?

The 990 Pro leads on reads (7,450 vs 7,400 MB/s) and IOPS. Both load games identically. The 990 Pro is more power-efficient and has broader brand recognition. At similar pricing, the 990 Pro edges ahead; when the FX900 Pro is discounted, it offers good value.
