Pure Accelerate 2019 comes at a pivotal time in Pure Storage's evolution from a flash storage pioneer to a publicly traded company with more than $1 billion in annual revenue. Flash vendors are grappling with uneven prices for NAND flash -- a scenario some analysts predict will linger for at least the next several years. Pure Storage all-flash storage is not out of the headwinds, although it appears to be weathering the storm for now. After back-to-back quarters of stalled flash sales, Pure all-flash revenue jumped last quarter. The company signed up more than 450 new enterprises, bringing its total customer base to around 6,600 paying customers.
