INTRODUCTION

   When the very first 2.5" SATA II (3Gb/s) consumer oriented solid state drives (SSDs) made their debut in the market roughly 15 years ago you'd be extremely lucky if you found a model surpassing 250MB/s in both reads and writes. The introduction of SATA III (6Gb/s) a few years later (first for 2.5" drives and later on for M.2) boosted that number to just over 450MB/s which compared to older mechanical drives was a rather significant improvement. In late 2015 we witnessed the introduction of the very first consumer oriented M.2 NVMe drives (PCIe 3.0 Gen3) which propelled read and write numbers to just over 2000MB/s thus producing up to 5 times higher performance compared to SATA III models. Later PCIe 3.0 Gen3 models easily surpassed 3000MB/s and the rest as they say is history. Today several PCIe 4.0 Gen4 M.2 NVMe SSDs can reach speeds of up to well over 7000MB/s and the brand new FX900 Pro model by HP (BIWIN) seems to be among them.

   HP ranks annually among the world's most recognized and valuable brands. Fuelled by innovative research and distinctive marketing, the HP brand is famous as a world leader in personal computers, printers, and other IT products. Under an official worldwide license, HP personal storage (SSDs, DRAM, and memory cards) products are designed, built, marketed, and sold by BIWIN Storage Technology. All trademarks are property of the respective brand owners.

   Just like many other PCIe 4.0 Gen4 M.2 NVMe SSDs in the market today the FX900 Pro line is also based on the Rainier IG5236 eight-channel NVMe v1.4 NAND flash controller by Innogrit which HP (BIWIN) has paired with DDR4L DRAM flash by Nanya (512MB/1GB/2GB/4GB for the 512GB/1TB/2TB/4TB models respectively) and 176-layer 3D TLC NAND flash by Micron. In terms of technologies the Innogrit Rainier IG5236 controller is fully packed with end-to-end data protection, LDPC (low-density parity check) error-correction with SRAM ECC, programmable RAID, smart cache, AES encryption, SHA, RSA, ONFI 4.1 and Toggle 4.0. HP (BIWIN) also uses a graphene thermal pad (reduces temperatures up to 18 degrees), covers the entire line with a 5-year limited warranty and reports an MTBF (meantime between failures) of 1 million hours together with endurance numbers of 300/600/1200/2400TBW for the 512GB/1TB/2TB/4TB models.
