Optimus Ascend™ SSD

Ideal for mixed-use environments and applications like collaboration, email and messaging, financial transactions, on-line transaction processing (OLTP) databases and virtual desktop infrastructure (VDI).


Optimus Ultra™ SSD

Optimus Ultra SAS SSDs provide performance, capacity, and reliability for databases and line-of-business applications, ERP, CRM, and on-line transaction processing.

Optimus Extreme™ SSD

Optimus Extreme SAS SSDs are designed for demanding write-intensive application workloads that need the highest levels of performance and reliability.


Optimus MAX™ SSD

Up to 4TB7 for read-intensive applications 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.
