Western Digital: WD Red Plus as the new NAS hard drive series

Western Digital is introducing new product names for some hard drives – for good reason. If you haven't noticed, Western Digital has hard drives specially marked for NAS use. But there were changes, so that WD Red with the technology Shingled Magnetic Recording (SMR) is commercially available. That technology can (does not have to) cause problems with a RAID rebuild under certain circumstances.

According to the WD, this should not be the case in a typical smart business or home area. However, Western Digital has obviously learned and will make it easier to see in the future whether hard drives rely on conventional magnetic recording (CMR) or shingled magnetic recording (SMR). The new models that work with CMR are now sold under the label WD Red Plus, apparently non-plus models are then Shingled Magnetic Recording (SMR).

Due to the fact that the use cases for NAS have become more and more diverse, the aim is to make it easier for users to find the right drive for their applications and workloads – from moderate SOHO workloads (small office / home office) to intensive use in Small and Medium Business (SMB) to more demanding environments. WD provides an overview:

WD RED with 2TB, 3TB, 4TB and 6TB is the choice for the majority of NAS users whose requirements are lighter SOHO workloads.

– WD Red Plus is the new name for conventional magnetic recording (CMR) NAS drives in the WD Red family, including all capacities from 1 TB to 14 TB. These disks will be the choice for those whose applications require more write-intensive SMB workloads like ZFS. WD Red Plus in 2TB, 3TB, 4TB and 6TB capacities will be available soon.

– The WD Red Pro (CMR 2TB to 14TB) series for the most intensive use remains unchanged.
