S840 400GB SAS MLC Bulk solid state drive
STEC™ s840 Enterprise SAS SSD
STEC™ s840 Enterprise SAS SSDs are ideal for use cases that require extreme I/O performance. These include VDI deployments, OLTP databases that need very fast response times, and SAN and NAS appliances that need a cost-effective-high IOPS for Tier-0 storage.
s840 drives outperform SATA SSDs and HDDs, achieving constant drive-life performance while delivering real-world high IOPS, a dual-port HA solution and the scalability to support mass deployments. The result is best-in-class price performance, enterprise-proven reliability, and the endurance to lower TCO and increase ROI.
The Right SSD For Enterprise Applications
A large number of SSDs claim high performance and reliability. However, data center operators and the enterprise can experience slower performance, device failure or data loss when using consumer SSDs not suitable for demanding true enterprise application workloads.
Understanding the capabilities of solid-state drives helps enterprises select the right solutions for their intended applications. STEC™ s840 Enterprise SAS solid-state drives comprise the universally accepted standard for I/O connectivity in enterprise storage and server systems to deliver the highest levels of performance and efficiency in data center servers and storage solutions.
