I don't have a direct summary link, but if you read random storage revenue/capacity reports that seems to be the case. There are a few large buyers of bulk storage which appear to be using it for some form of nearline. At least in my experience (which is obviously warped by the part of the industry I was in), enterprise applications needing IOP's have been overwhelmingly moving to pure flash. There remains a large amount of revenue in hybrid arrays, but the volume is shrinking (although maybe not the raw capacity, similar to the mainframe which is selling record amounts of capacity in fewer and fewer machines). A few years ago I stopped being surprised to see a couple racks of infortrend's or supermicro storage chassis (or any number of other 2nd tier vendors products) sitting at one end of random datacenters, where the local storage admins were running some huge snapshot repo, or Ceph, or whatever on them and the resulting capacities were frequently powers of ten greater than the online storage. Also, I've seen plenty of tape arrays too, but they don't seem nearly as common these days. Partially, because tape has the same problems as disk (lots of bandwidth, but it never seems to be enough). It seems everyone still has one, but you have to hunt for it, and it might only be getting the most critical data (or stuff that is required for compliance with some law), which turns out to be limited by the 2-4-8 drives they have constantly spinning, where an operator walks in every few days and swaps a couple dozen tapes offsite. Sure there are larger libraries but it seems most admin's start any conversation about tape with a groan and eye rolling, which tends to be an attitude that keeps finite resources from being heavily invested in them. So, people will buy 10+Gbit links between their data centers (which sometimes tend to be shockingly inexpensive) rather than spend $10k on a tape library and a fedex account.
