WD haven’t advised about SMR in their external drives. Evidence and testing seems to suggest you’d be safe with 8tb and above drives.
What is a good non smr external drive ?
WORM is what it is designed for but the naughty manufacturers are miss using it in products it shouldnt be in. Should only be used really for archival usage
Seagate are no better. I picked up a 2tb Barracuda 7200rpm on a whim when building the system as a place to keep my Plex media. Big mistake. It drops down to 10mb/s write after the first gigabyte or two has been written. The logic is inverse to what makes sense to me. It is used to enhance capacity - I foolishly assumed 2tb was so small these days it'd be fine, but the technique would be used in order to try and extract more capacity from the larger drives. SMR should be viewed upon as a write once(slowly), read many media type.
Because they put them in their Red series, which are marketed as designed for RAID, when they are anything but. These were/are sold standalone. It's got nothing to do with being a tightwad. Now that we know which are SMR and which are CMR, in personally still perfectly happy to buy WD drives if the price is right.
