# HP FX900 256GB -- Budget PCIe 4.0 NVMe SSD Review (2026)

The HP FX900 256 GB is the entry-level capacity in HP's mainstream PCIe 4.0 SSD line, built on the DRAM-less InnoGrit IG5220BAA controller for budget-conscious builds.

Quick answer: The 256 GB FX900 is a bare-bones budget PCIe 4.0 boot drive. Its 4,600/1,700 MB/s speeds are adequate for OS use but below what mid-range PCIe 4.0 drives deliver. The 100 TBW endurance is low — appropriate for light workloads only. At this capacity and price tier, the Kingston NV2 256 GB and WD Blue SN580 256 GB are direct competitors. Choose the FX900 if it is the cheapest option; otherwise, the WD Blue SN580 offers better sustained performance at similar pricing.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 256 GB |
| Interface | M.2 4.0 x 4 |
| Controller | Innogrit IG5220BAA |
| Memory type | MicronTLC |
| DRAM cache | HMB |
| Sequential read | 4600 MB/s |
| Sequential write | 1700 MB/s |
| Random read IOPS | 820000 |
| Random write IOPS | 645000 |
| Endurance | 100 TBW |
| MTBF | 1500000 |
| Warranty | 5 years |

## Performance

The 256 GB FX900 delivers 4,600/1,700 MB/s sequential reads and writes with up to 820,000/645,000 read/write IOPS. The HMB architecture provides adequate random I/O for light desktop use but transitions to native NAND speeds faster than DRAM-equipped drives under sustained writes. For OS boot and application launches, the experience is responsive.

## Endurance, TBW & Warranty

HP covers the FX900 256 GB with a five-year warranty limited by 100 TBW, equivalent to roughly 55 GB/day over five years. The 512 GB model carries 200 TBW, 1 TB 400 TBW, and 2 TB reaches 800 TBW.

## Pros and Cons

**Pros:**

- 4,600 MB/s reads -- adequate for boot drive
- DRAM-less HMB design keeps price low
- Single-sided PCB -- thin-laptop compatible
- 5-year warranty
**Cons:**

- 1,700 MB/s writes -- well below mid-range
- 100 TBW endurance -- lowest in the lineup
- 256 GB tight for modern use
- No DRAM -- slower sustained random I/O


## Verdict

The 256 GB FX900 is a bare-bones budget PCIe 4.0 boot drive. Its 4,600/1,700 MB/s speeds are adequate for OS use but below what mid-range PCIe 4.0 drives deliver. The 100 TBW endurance is low — appropriate for light workloads only. At this capacity and price tier, the Kingston NV2 256 GB and WD Blue SN580 256 GB are direct competitors. Choose the FX900 if it is the cheapest option; otherwise, the WD Blue SN580 offers better sustained performance at similar pricing.

## Frequently Asked Questions

### Is the 256GB FX900 good for basic PC builds?

Yes — 4,600 MB/s reads provide responsive OS boot and application launches. The 256 GB capacity is sufficient for Windows, core applications, and a few games. For larger libraries, step up to 512 GB or 1 TB.

### What is the TBW of the 256GB FX900?

Rated for 100 TBW over five years, equivalent to roughly 55 GB/day. At light use of 10-15 GB/day this lasts 18-27 years.

### Does it have DRAM?

No — the FX900 uses a DRAM-less HMB (Host Memory Buffer) design, which borrows a small amount of system RAM for the flash translation layer. This keeps costs down but reduces sustained random I/O performance compared to DRAM-equipped drives.

### How does it compare to the Kingston NV2 256GB?

Both are DRAM-less budget PCIe 4.0 drives. The NV2 rates at 3,500/2,100 MB/s. The FX900 leads on reads (4,600 vs 3,500) but trails on writes (1,700 vs 2,100). Both are adequate for boot drives.

### Can I use it for PS5?

Technically yes — it fits the M.2 2280 bay and exceeds the 5,500 MB/s read minimum is not met (4,600 MB/s). However, Sony recommends drives at 5,500 MB/s minimum, and the 256 GB capacity holds only one or two large titles. Not recommended for PS5.
