There is a sticker on the back of the HP FX900 Pro 2TB with the product model and serial number. The 2TB capacity naturally has a double-sided PCB design. There are flash memory particles under the sticker. The product provides a five-year 1200TBW after-sales warranty, which is the most common flagship in the industry. Grade products are consistent. With this maximum TBW, as long as it is used under normal circumstances, the actual lifespan will definitely be far more than five years.

Remove the heat sink and sticker and you can see the PCB. The front is the main control, a cache, and two flash memory particles, and the back is another cache and two flash memory particles. It is not recommended to put the heat sink and the two flash memory particles under normal use. When the sticker is peeled off, it may become dirty or deformed.

In the center of the front of the PCB is RainierPC (Innogrit IG5236), the main control unit of SSD, which is based on the 12nm FinFET CMOS manufacturing process and supports the NVMe 1.4 protocol and 8-channel flash memory. It is a high-end PCIe 4.0 consumer-grade main control solution. The area on the left is 176-layer 3D TLC NAND flash memory particles from Micron, each with a capacity of 512GB.

The area on the right is a cache chip from Nanya, model NT5AD512M16C4-JR, factory frequency DDR4-3200 CL20, single chip capacity 1GB.

The back of the PCB corresponds to the layout of two other flash memory particles and one cache particle. The model and front components are consistent.

Check the SSD information through CrystalDiskInfo. HP FX900 Pro 2TB supports NVME 1.4 protocol, SMART, TRIM, and Volatile Write Cache functions. It has a standard PCIe 4.0×4 interface and the firmware version is 3.AF12. The SSD is brand new and unused and has no data volume. It is on standby and the temperature under no-load conditions is approximately 40°C.

Performance and Benchmarks

In the CrystalDiskMark test, the HP FX900 Pro SSD’s sequential reading speed is 7134.04MB/s and the writing speed is 6623.41MB/s. The 4K multi-threaded random reading and writing speed is 1095.02MB/s reading and 986.09MB/s writing. The performance is very good. Whether it is sequential reading and writing, or 4K reading and writing, it is a proper flagship-level PCIe4.0 solid state.

In the AS SSD test, the HP FX900 Pro SSD sequentially read 5773.37MB/s and write 5665.22MB/s, with a total score of 11391, which is a very high score. As can be seen from the IOPS results, the 64-thread IOPS performance of 4K is also excellent.

In the AS SSD Copy test, the ISO file transfer rate reached 3811.21MB/s, with a duration of 0.60s; the program transfer rate reached 2411.08MB/s, 2.24s; the game transfer rate reached 2105.04MB/s, 0.66s, The performance was outstanding.

TxBench will more fully squeeze the extreme performance of SSD! so the sequential performance is better than the AS SSD Benchmark. However, the test items of these two software are similar. Except for the sequential score check, the scores of other parts are no different from the AS SSD Benchmark. Interested friends can take a closer look and will not go into details here. The sequential read and write speeds of FX900 Pro are 6763MB/s and 6405MB/s, both reaching the 7GB/s level! 4K random (QD1) read and write are 92MB/s and 332MB/s, which are basically similar to the previous test results.

The Anvil SSD benchmark results show that the HP FX900 Pro SSD’s read performance score was 10,059.51 points, the write performance was 17,885.50 points, and the total score was 27.945.01 points.
