September 9, 2014, Intel Developer Forum, San Francisco—One issue for systems performance is constrained by the SSD actual versus specified parameters. The operating conditions can dramatically affect IOPS and latency, which are the drivers for changing a storage tier to SSDs in the first place. The first challenge is the concurrency effects of multiple die…
September 18, 2013, Storage Developer Conference, Santa Clara, CA—Peter Murray from SwiftTest suggested that IOPs is not a good metric for characterizing and testing storage performance. The problem is that this measurement doesn’t acknowledge the contributions of the other systems components to storage performance. Storage performance validation has evolved from blind reliance on vendor claims,…
At the Flash Memory Summit in August, Samsung presented thier offering on UFS interface Flash. The UFS interface (Universal Flash Storage) is a new memory multi-device specification for both embedded and removable memory. The specification is based on performance in IOPS rather than MB/s as the driver. The initial release is a poit to point…
