Overview

The SanDisk Optimus2 Eco SDLKOCDR-800G-5C is an enterprise-grade solid-state drive built for data center and server environments where consistent performance and write endurance are critical. With 800GB of usable capacity and MLC NAND flash manufactured on a 19nm process, the drive is positioned for mixed-use workloads that demand a balance between read and write performance. The 3 DWPD endurance rating allows for approximately 2.4TB of data to be written daily over the drive's warranty life, supporting applications such as database hosting, email servers, and virtualization platforms.

The Optimus2 Eco connects via a SAS 6Gb/s interface, the standard for enterprise storage at the time of its release. SAS offers advantages over SATA in enterprise settings, including dual-port capability for failover and multipath I/O, full-duplex communication, and broader command queuing. The 2.5-inch form factor with a 9.5mm thickness ensures compatibility with standard enterprise server drive bays and storage enclosures. This drive is designed for organizations running SAS-based infrastructure that need dependable, endurance-rated solid-state storage without moving to the latest generation of SAS 12Gb/s or NVMe drives.

Pros & Cons

👍 Pros

  • 800GB capacity provides substantial storage for enterprise database and application workloads
  • 3 DWPD endurance rating supports sustained mixed read/write operations in production environments
  • MLC NAND delivers better write endurance compared to TLC-based enterprise drives
  • SAS 6Gb/s interface supports dual-port connectivity for high-availability configurations
  • 2.5-inch 9.5mm form factor fits standard enterprise drive bays without adapters

👎 Cons

  • SAS 6Gb/s interface is a previous generation, with newer drives offering 12Gb/s SAS speeds
  • Requires a SAS controller or backplane, making it incompatible with consumer SATA-only systems
  • 19nm MLC NAND is an older fabrication process, superseded by newer, denser NAND technologies
  • No hardware encryption features mentioned, which may be required in some enterprise security policies
  • Capacity tops out at 800GB, which is modest compared to current multi-terabyte enterprise SSDs

Frequently Asked Questions

The Optimus2 Eco uses a SAS 6Gb/s interface, which is standard in enterprise server and storage array environments and supports dual-port connectivity for high availability.
The drive is rated at 3 Drive Writes Per Day (DWPD), meaning the entire 800GB capacity can be written three times daily over the warranty period, suitable for mixed read/write enterprise workloads.
It uses 19nm MLC (Multi-Level Cell) NAND flash, which provides a balance of endurance and capacity that is well-suited for enterprise mixed-use applications.
Yes, it is a standard 2.5-inch form factor with a 9.5mm thickness, compatible with most enterprise server and storage enclosure 2.5-inch drive bays.
No, the Optimus2 Eco uses a SAS interface, not SATA. It requires a SAS host bus adapter or SAS-capable backplane typically found in enterprise servers and storage arrays.
