Write Once Read Mostly
Shingled media is almost useless for random access, since rewriting a logical block means relocating its entire "shingle" strip somewhere else., then, at some other time, garbage-collecting the entire region and relocating the still-in-use blocks. You definitely want to run these "noatime", to prevent thrashing directory blocks, and they should probably have a new filesystem designed for them.
Some have tried tinkering with flash filesystems due to the "copy/invalidate/garbage collect" and the LBAs are gathered in some larger storage block in no particular order, and that storage block needs to be managed. Don't know if Seagate will tell us what the size of a erase block (a set of overlapping, concentric "shingles", which have to be collected as a group) really is, or if they'll even be a consistent size.
If you're streaming from them, you may hit "garbage collect" long access times, and I don't know what proprietary commands and settings may be available, if any, to tell the drive "now is a good time to do housekeeping".
As "archive media", shingled drives probably work OK, since that is a WROM application, but, personally, I would NOT use them on any existing file system.
