Flash storage offers dramatically faster performance over traditional spinning magnetic disk storage technology, but many enterprises have postponed adoption of it because of cost concerns. But it’s not as expensive as you think.
“When the storage efficiency techniques and the ability to safely use lower-cost memory are combined, all-flash storage systems can typically match the price of high-performance, tier 1, HDD-based storage systems,” says Storage Switzerland Senior Analyst George Crump. “What’s more, they’re now working their way into the price-band of tier 2 storage systems.”
Crump believes that a multi-step approach to driving down flash costs will help the enterprise reduce its overall storage costs. He suggests techniques like thinly provisioning all volumes on the system to make sure that capacity is only used when it’s actually needed and minimizing the data being written through the always-on deduplication and compression capabilities of flash storage.
