"The data intensity of typical small business/home NAS workloads is intermittent, leaving sufficient idle time for DMSMR drives to perform background data management tasks as needed and continue an optimal performance experience for users."
A NAS drive, which features RAID specific firmware no less, is _very_ likely to be put in a RAID, and rebuilding the RAID after replacing a disk is exactly the opposite of an intermittent workload.
What they should have done is this:
- Change the name slightly, "WD Red Lite" or something.
- Make sure the product information page (and firmware if applicable) says this is a DM-SMR drive.
- Say it is intended for single-disk or RAID-1 (mirror) setups, and is not recommended in RAID-5, RAID-6 or similar setups, with links to their Red Pro disks for that.
That would allowed them to capitalize on the "WD Red" name as something consumers have heard about, while also not right out lying about a very important aspect of the product.
