No it doesn't.
Reading doesn't cause (much) wear on an SSD - writing does.
(To be technical - it does, but it only requires 1 write / 100,000 reads or so. - https://en.wikipedia.org/wiki/Flash_memory#Read_disturb https://en.wikipedia.org/wiki/Flash_memory#Read_disturb )
- frankmcsherry 12y agoThis probably isn't crystal clear from this post alone, but for PageRank the 42GB working set has a good mix of read and write. Specifically, about 14GB of target rank vector gets +='d all over the place. If they got hammered randomly, then lots of paging and writing would happen.
