The flash flood According to Ovum, flash storage is cheaper than traditional storage in dollars-per-data-throughput-speed (IOPS).

The two biggest trends in storage at present are the use of flash memory in the data centre and public cloud storage, according to Tim Stammers, senior analyst at Ovum.

Public cloud storage will take a long time to be adopted, but it will significantly change the face of the storage industry; flash memory will also significantly change the face of the storage industry at a very detailed level. Storage is very much a technical plumbing subject and flash is going to change the way storage systems are put together, said Stammers.

“Flash is a blessing for IT, because it is solving the growing challenges created by the performance limitations of disk storage. A common misconception is that flash storage is expensive, and only suits exotic, high performance applications. The reality is that flash is already boosting performance and reducing costs in a range of other settings, including but not limited to mainstream database and front-office applications, Microsoft Exchange, and server and desktop virtualisation,” he said.

According to Ovum, one of the most important parameters for flash is dollars-per-gigabyte capacity, and there it is much more expensive than disk, but in dollars-per-data-throughput-speed (IOPS) flash is about 40 times cheaper than disk in terms of dollars per IOPS, meaning that companies are likely to start investing more into flash storage.

Key messages of Flash:
• Flash usage will grow rapidly
• Flash technology is very different to disk, and is still developing
• Deployment choices demand new thinking from IT
• Buyers are spoilt for choice in deployment options
• Treat benchmark performance claims with even more care than usual
• Flash life can be long, but is complex
