Came across this article on TechRadar and it caught my attention. Especially the following, “The ten-disk hard drive, which is based on shingled magnetic recording (SMR) technology”.

My understanding is that SMR drives are not all that good for RAID setups. So I’m curious as to why this type of drive would be a good candidate for data centers. Thoughts?

    Your understanding is incorrect. Only DMSMR drives are not very good because the disk is managing zones like a black box. HMSMR are great because user have full control on how to write data, thus eliminating all the shortcomings.
