HGST incorporates specialized software and hardware that combine to implement Storage Class 

Memory (SCM) within the server. The HGST architecture has been designed to tightly integrate 

different kinds of Flash media, hardware and software to deliver memory-class performance 

with storage-class capacity and persistence. HGST’s FlashMAX® II SCM devices and associated 

software deliver performance without compromise, along with HDD-like capacity in a very 

compact, universal form factor.

vFAS is an Adaptive Scheduling algorithm, which delivers the most efficient access to Flash 

media for applications. In addition to providing optimized access for peak performance, 

vFAS also includes sophisticated techniques to ensure applications get steady sustained 

performance at all times. vFAS virtualizes the underlying Flash media to present a standard 

block device interface to applications, without inefficient storage protocols or interconnects, 

resulting in significant gains in application performance.

FlashMAX II presents a traditional block storage volume to the host so that applications 

can easily access it without modification. vFAS has been designed to treat Flash media 

more like an extension of memory, while maintaining a traditional block storage interface 

for applications. All of this is done without the use of storage protocols, storage controllers 

or storage interconnects. The result is latencies under 30 μs, which is closer to DRAM 

performance. 

FlashMAX II with vFAS delivers consistent performance across all application workloads, 

even when the device is fully utilized. FlashMAX II with vFAS delivers application 

performance whether it is peak small block read performance, where a single low profile 

card can deliver over 1.1 million IOPS, or sustained mixed read/write performance when the 
drive is full. 

Unlike many competing solutions, 100% of the capacity available on a FlashMAX II card 

is available as a single host volume on the server without having to leverage 3rd party 

software RAID products to stripe across multiple drives. With FlashMAX II you can have a 

single volume presented to the operating system up to the advertised formatted capacity, 
which can be as large as 4.8TB when using the FlashMAX II Capacity model.
