The disks are SMR. As drives have gotten bigger, shingled magnetic recording, or SMR, has become a key technology. Larger data centers and systems providers want to manage the SMR process which adds a twist. We are pulling this quote directly from the
press release:
“Host-managed SMR hard drives are designed specifically for sequential write environments, and will not work as drop-in replacements for traditional capacity enterprise drives.” (emphasis added)
Although these are enterprise drives, you need a system that can manage them so do not expect to use the drives in a lower-end NAS unit. At the same time, those using 14TB capacity drives are using them in engineered systems that provide host-managed SMR so this is not an issue. It also shows that why we are seeing QLC in the data center as every time flash can overcome a cost obstacle it enters a new market of competition against hard drives that are having issues scaling.
