Caching Beyond RAM: The Case for NVMe
What's the lifetime of an optane or NVMe drive when used as a constantly thrashing cache? Weeks? Months?<p>Edit: Missed this the first time through:<p>> <i>Calculating this is done by monitoring an SSD's tolernace of "Drive Writes Per Day". If a 1TB device could survive 5 years with 2TB of writes per 24 hours it has a tolerance of 2 DWPD. Optane has a high tolerance at 30DWPD, while a high end flash drive is 3-6DWPD.</i>
