Intel Highlights Optane's Unique Speed and Persistence, Says Tech Central

Intel’s Optane line still commands attention because it delivers latency that rivals DRAM while retaining the non‑volatile nature of flash, a claim underscored by Tech Central’s recent deep‑dive into the P4800X, P5800X and consumer 900P/905P models. The drives are built on 3D XPoint, the memory technology co‑developed by Intel and Micron, which “has aspects of DRAM and regular NAND‑based Flash” (Tech Central). In practice, the P5800X can sustain 1.5 million 4 KB read IOPS and 1.5 million write IOPS, with a read bandwidth of 7.2 GB/s on a PCIe 4.0 interface—far outpacing the 2.5 GB/s read speed of the first‑gen P4800X on PCIe 3.0 (Tech Central). This raw performance translates into ultra‑low access times that are “ultra low latency, high durability and high performance” according to the same source, making Optane attractive for workloads that cannot tolerate the millisecond‑scale delays typical of NAND SSDs.

Durability is another differentiator. Optane’s write‑intensive endurance is rated at 30 DWPD (Drive Writes Per Day) for the P4800X and a striking 100 DWPD for the P5800X, eclipsing the 10 DWPD ceiling of the best‑in‑class NAND‑based professional drives (Tech Central). The higher endurance is paired with power‑loss protection, a feature absent from most consumer QLC drives but present on the Optane models (Tech Central). This combination means data integrity is preserved even under abrupt power cuts, a critical requirement for enterprise databases and high‑frequency trading platforms that cannot risk corruption.

Despite these technical merits, Optane’s market traction has been limited by price and capacity. The 375 GB‑1.5 TB P4800X and the 400 GB‑3.2 TB P5800X carry a premium that “high cost and relative low capacity” make prohibitive for many organizations (Tech Central). Moreover, the rapid advancement of NAND SSDs and the emergence of Compute Express Link (CXL) have narrowed the performance gap, prompting Intel to halt further Optane SSD innovation in July 2022 as part of its IDM 2.0 strategy (Tech Central). Nonetheless, Intel continues to sell existing Optane SSDs and DIMMs, and it introduced a new Optane Persistent Memory (PMEM) 300 series NV‑DIMM to complement the fourth‑generation Sapphire Rapids Xeon Scalable CPUs launched in January 2023 (Tech Central). ServeTheHome’s video on Optane Persistent Memory illustrates how the technology can provide byte‑addressable, persistent storage directly attached to the memory bus, blurring the line between RAM and storage.

Industry analysts remain divided on Optane’s long‑term relevance. VentureBeat’s feature on “Optane persistent memory: breakthrough or pending promise?” notes that while the technology offers a compelling “high‑octane” memory tier, its adoption hinges on software ecosystems that can exploit persistent memory semantics (VentureBeat). Ars Technica points out that 3D XPoint’s promise of “changing the world” still faces hurdles in cost‑effectiveness and broader developer support (Ars Technica). CNET echoes the performance narrative, describing Optane as “high‑octane memory” that improves launch and load times without sacrificing speed for storage capacity (CNET). Together, these perspectives suggest that Optane’s niche remains in high‑performance, data‑intensive environments where latency, durability, and persistence outweigh the premium price tag.

In practice, the technology’s strengths are evident in real‑world testing. A VMware vExpert who evaluated the P4800X reported “ultra‑low latency and high durability” that made the drive feel “more like DRAM than flash,” thanks to the underlying 3D XPoint cells (Tech Central). The tester also highlighted the drive’s ability to sustain write‑intensive workloads without throttling, a direct result of its 30 DWPD rating (Tech Central). While the author acknowledges the “high cost and relative low capacity” as limiting factors, the hands‑on experience confirms that Optane still delivers a performance envelope unmatched by conventional NAND SSDs, particularly for workloads that demand consistent, low‑latency access and robust data integrity.
