SSDs from SanDisk eye enterprise, data centre apps
SanDisk has introduced four additional solid state drives (SSDs) to its CloudSpeed Serial ATA (SATA) product family to meet demands of enterprise workloads. According to the company, the SSDs leverage software to address endurance challenges, particularly those created by write-intensive application workloads.
The CloudSpeed Eco, Ascend, Ultra, and Extreme SSDs are all aimed for use in enterprise data centres and cloud computing environments.
Brian Cox, senior director of outbound marketing for SanDisk Enterprise Storage Solutions, said one of the primary concerns for enterprises when adopting SSDs into their computing environments is maintaining uptime and a level of service. When an SSD fails on a client device, only one user is affected, and the SSDs are not optimized for particular workflows. He said the CloudSpeed SSDs are specifically geared at addressing specific enterprise and cloud computing uses cases while leveraging flash management software to improve the endurance and longevity of the SSD.
At the entry level is the CloudSpeed Eco, designed for read-intensive application workloads such as web servers, web 2.0 content repositories, photo sharing, media streaming, video on demand, and cloud computing. One step up is the CloudSpeed Ascend, which is aimed at read-intensive application workloads such as file servers, web-based apps, and virtual tape libraries.
Further up is CloudSpeed Extreme, a high-endurance SSD for write-intensive application workloads such as database logging and high performance computing. Finally, at high end, is SanDisk's CloudSpeed Ultra, which is aimed at mixed-use application workloads such as online transaction processing, financial transactions, email/messaging, e-commerce and virtual desktop Infrastructure (VDI).
All four make use of SanDisk's flash management Guardian Technology Platform to improve the lifespan of the drives by extending the native endurance of MLC flash while providing full data path protection, including data protection from power loss. The entry-level CloudSpeed Eco has a warranty of three years, while the other three come with five-year warranties.
Cox said the costs of SSDs are continuing to plunge to the point where CAPEX is surpassing that of spinning disks. SSDs can run faster on less power and at cooler temperatures with more capacity and greater density. Hard drives can no longer keep up in terms up reliability, longevity or performance, he added, especially for write-intensive applications such as VDI.
Cox said SanDisk is now seeing some startups skip spinning disk infrastructures completely and opting to go all flash for their computing environments.
