Best PCIe SSD: Intel Optane SSD DC 4800X Series – Product Overview and Insight

See our full list of 7 Best and Fastest SSDs

Bottom Line:

The Intel Optane SSD DC P4800X is best for buyers who require fast caching and fast storage to increase scale per server and reduce transaction costs for latency sensitive workloads.

For those with high write environments, the Optane can withstand intense write traffic that is typically demanded of memory. This includes online transaction processing (OLTP), high performance computing (HPC), write caching and logging. The Western Digital PC SN720 just beats it for raw throughput, but the enterprise credentials of the 4800X make it the best choice for enterprise storage workloads.

Product Description:

The Intel Optane SSD helps eliminate storage bottlenecks to enable bigger, more affordable data sets. It can accelerate applications, reduce transaction costs for latency-sensitive workloads, and improve overall data center TCO. The P4800X is a single port device. It is compatible with PCIe Gen3 x4 speeds. It is the only product on the market that utilizes 3D Xpoint technology and offers latency as low as 10 microseconds.

Based on 64-layer Intel 3D NAND TLC, it accelerates read-intensive workloads at higher service levels and improves overall system reliability and flexibility. SATA firmware adds compatibility with existing SATA arrays to make upgrades easy. Capacity ranges from 240 GB up to 7.68 TB in a standard 2.5-inch form factor. At the same time, these SSDs offer high performance and low power consumption. Those choosing to upgrade their storage arrays from HDDs to these SSDs can add hundreds of times more IOPS.

The flex workload feature of the Optane enables a common drive type to cover more workloads with flexible capacity, flexible endurance, and flexible power-efficient performance. Additionally, end-to-end data protection helps keep data safe regardless of power loss.

Key Markets and Use Cases:

The Intel Optane SSD DC P4800X is ideal for enterprise storage workloads that require fast read and write caching or a superfast storage tier to cope with the demands of OLTP and HPC operations.

Enterprises looking to replace Hard Disk Drives (HDDs) can turn to these efficient Intel SSDs as a way to reduce storage operating costs, accelerate read-intensive workloads. Those with aging arrays who wish to gain further value from them can swap out HDDs easily due to the SATA firmware which solves compatibility issues. Once the SSDs are installed, the firmware completes updates without reset in order to minimize downtime.

Another use case is applications that need high performance and low power consumption. With capacities topping out at 7.68TB in a 2.5-inch form factor, the drives consume up to 6 times less power and 6x less cooling requirements than 2.5-inch HDDs.
