Did you know that all-flash primary storage on average improves the performance of most storage-bound applications by a factor of ten?
While this boost in performance is a clear benefit of flash storage, solid state arrays can afford a number of additional advantages too, especially when you consider the total cost of ownership (TCO).
Why TCO is in favour of flash
Despite the fact that the comparative cost of HDD versus all-flash for the same quantity of raw capacity remains in the favour of the former, the TCO is a different story. This is something that Gartner recently analysed in its “Solid-State Array TCO Reality Check” research article.
As authors Joseph Unsworth and Arun Chandrasekaran explained: “Justification of investment for SSA deployments compared with previously installed HDD-based ECB storage systems averaged out to a ROI of 5.4 months.”
Much of the savings come from not having to purchase as much physical raw capacity as HDD or hybrid because of the data reduction features available with all-flash arrays. However, Gartner believes there are other tangible TCO savings to be had relating to:
• Maintenance – There will be a 16 per cent reduction in maintenance costs compared with previously installed HDD-based ECB storage systems
• Power – There will be a 76 per cent savings in power and cooling costs compared with the previously installed HDD-based ECB storage systems
• Space – There will be a 63 per cent savings in terms of rack space compared with the previously installed HDD-based ECB storage systems
• Administration – There will be 48 per cent savings in terms of time and money compared with previously installed HDD-based ECB storage systems
Even if your existing HDD or hybrid storage solutions still have time to run, it might be worth switching to a packaged offer including a trade-in rebate and pay-as-you-go pricing to enjoy the merits of all-flash sooner rather than later. It is only a matter of time before more businesses realise that the reasons for adopting flash storage are not just limited to performance.
