In Howard Marks’ Network Computing column yesterday, he makes the point that there are different performance tiers among SSD storage arrays. He uses a car metaphor to differentiate vendor offerings by speed. It is fun, creative and definitely flattering to be compared to a Lamborghini. However, as we usually do, we would like to make a few comments.
Speed is not enough to distinguish among SSD storage arrays
We started 2012 off by proclaiming it was the Year of the SSD. Since then, we have discussed frequently that while IOPs and latency are important to convince organizations to adopt SSD, speed is not enough. Data protection and high availability are particularly important to enterprise customers. Many customers we speak with say data protection is equally important to them as speed in determining whether to adopt SSD arrays in their data center. So it would be nice to extend Marks’ car metaphor to include data protection. In fact, if a Lamborghini could cross-breed with a Volvo, the offspring would be a lot closer metaphor for the Kaminario K2.
