SanDisk SDLLOCDR-038T-5CA1 4TB 2.5" 6Gbps Optimus MAX eMLC SAS SSD - New Pull

SanDisk SDLLOCDR-038T-5CA1 4000GB 2.5" 6.0 Gbps Optimus MAX Enterprise Multi-Level Cell Serial Attached SCSI Solid State Disk Drive - New Pull

Achieve ultimate capacity and scalability for maximum TCO savings

The Optimus MAX™ 4TB SAS SSD is the first SSD of its kind to deliver SAS performance and features at the cost of SATA SSD-like prices for enterprise, cloud and virtualized data centers. This 4TB SSD enables organization to transition to a leaner infrastructure model, for maximum total cost of ownership (TCO) savings and surpasses the current high capacity 2.5" SAS SSDs and 2.5” SAS HDDs on the market today. The Optimus MAX SSD is optimized for read-intensive application workloads such as, Data Warehousing, Media Streaming, Web Servers, Video on Demand (VOD), and Web-based Applications with a typical workload comprised of a 90/10 read/write mix. This 4TB SAS SSD alleviates I/O bottlenecks by providing high-density storage for efficient data throughput to deliver, high performance, superior reliability and enhanced endurance for maximum application scalability.

The Optimus MAX 4TB SAS SSD features industry leading 19nm eMLC with a native 6Gb/s SATA interface and provides data transfer rates of up to 500/500MB/s sequential read/ write and performance of up to 65K/10K IOPS random read/write. This SSD offers 1 full drive write per day (DWPD) with a limited 5 year warranty. The Optimus MAX 4TB SAS SSD removes the flash capacity barrier for replacing 10K and 15K RPM SAS HDDs and provides an ideal solution for true storage stack applications.

Guardian Technology™ Platform

The Optimus MAX 4TB SSD is powered by SanDisk’s innovative Guardian Technology Platform, a comprehensive suite of enterprise features comprised of FlashGuard™, DataGuard™ and EverGuard™ technologies.

FlashGuard Technology combines Aggregated Flash Management, which treats all flash elements as a single system, and Advanced Signal Processing, which dynamically adjusts flash parameters throughout the life of the SSD, to reliably extract significantly more life from commercial-grade MLC flash, making it suitable for mixed-use application workloads.

DataGuard Technology features full data path protection, safeguarding user data from corruption along all data paths in the SSD. DataGuard also protects the SSD against loss of data at the page and block levels using a unique feature called F.R.A.M.E. (Flexible Redundant Array of Memory Elements). F.R.A.M.E. acts as a data recovery feature that enables the recovery of user data even after catastrophic events such as flash page or block failures.

EverGuard Technology protects against loss of user data in the event of unexpected power interruptions using a 3rd generation backup power circuit design and high reliability discrete capacitors.


This drive is compatible with any server that accepts 2.5" x 15mm (SFF Hard Drive) SAS drives.
