So what about SSDs? There’s no question SSDs are in Linode’s future, however enterprise-class SSDs (SLC or eMLC based) are prohibitively expensive. And although MLC-based drives are cheaper we just don’t feel right about using consumer grade laptop drives to power your Linodes. So we will wait until capacities for enterprise SSDs increase.
