Quick answer
Current model answer
Western Digital’s cited current Red Plus data sheet lists every current model as CMR. The range runs from 2TB to 12TB and includes multiple models at several capacities, so the Red Plus name alone does not identify speed, cache, power or acoustics. Verify the complete model number, especially at 8TB, 10TB and 12TB.

Current-model lookup
Enter the base model number printed on the drive or listing. A missing result does not prove a drive is SMR; it means it is not in the cited current model table.
Every model in the current Red Plus table is CMR
Western Digital’s current Red Plus data sheet lists CMR for every model from 2TB through 12TB. This is the clearest distinction between Red Plus and the plain WD Red family, which has included device-managed SMR products. Western Digital specifically positions Red Plus and Red Pro as CMR choices for more demanding NAS and ZFS workloads.
The all-CMR statement applies to the cited current Red Plus model table. Retailers may still sell older WD Red and Red Plus revisions, recertified drives or mislabeled marketplace products. Confirm the exact model number rather than relying on a red label, capacity or combined review page.
Current Red Plus drives share a 180TB-per-year workload rating, up-to-eight-bay target, one-million-hour MTBF class and three-year limited warranty. They do not share one RPM, transfer rate, cache size, power figure or acoustic profile.
Why a Red Plus model list is necessary
At 8TB, Western Digital currently lists WD80EFPX and WD80EFZZ. Both are CMR and 5,640 RPM, but EFPX is rated up to 215MB/s with 256MB cache, while EFZZ is rated up to 185MB/s with 128MB. EFPX also has lower cited power and acoustic figures. A generic “8TB Red Plus” recommendation can therefore hide a meaningful specification difference.
At 12TB, the difference is even larger. WD120EFGX is an air-filled performance model rated up to 260MB/s with 512MB cache. WD120EFBX is a helium-filled model rated up to 196MB/s with 256MB cache, but it has dramatically lower idle power and acoustics. The better model depends on the NAS location and workload.
Model lists also help with replacements. An exact match may be preferred for an existing array, while a current alternative can be better for a new build. The right decision requires knowing which model is actually being offered.
Current 12TB and 10TB models
The current 12TB models are WD120EFGX and WD120EFBX. Both are CMR and 7,200 RPM, but their air-versus-helium platforms create very different speed, power and noise profiles. The current 10TB models are WD100EFGX and WD101EFBX, also CMR and 7,200 RPM, with 512MB versus 256MB cache and 260MB/s versus 215MB/s rated transfer.
These paired capacities show why RPM alone is not enough. Two drives can spin at the same speed and still have different transfer rates, cache, acoustics and energy use. Compare the exact row and current price rather than assuming the last letters are a trivial manufacturing code.
High-capacity drives reduce the number of bays required for a target capacity but increase rebuild size. Plan backup, spare strategy and future expansion. Confirm that the NAS model and operating-system version support the exact capacity and drive.
Current 8TB and 6TB models
WD80EFPX and WD80EFZZ are the current 8TB models in the cited table. WD60EFPX and WD60EFZX are the current 6TB models. All four are CMR, but EFPX models carry 256MB cache while the alternative models listed here carry 128MB. Transfer and power figures also differ.
For a new 8TB array, WD80EFPX is the stronger specification at similar pricing. WD80EFZZ becomes a value option when the discount is significant or when it matches an existing validated array. At 6TB, compare the same factors rather than choosing by one suffix or a combined review score.
A listing that says “NASware” or “for NAS” does not prove that the selected variation is Red Plus. Confirm the model begins with the exact code shown in the table and check the product detail section after selecting the capacity.
Current 4TB and 2TB models
The cited current 4TB models are WD40EFZZ and WD40EFPX, both CMR and 5,400 RPM with the same 180MB/s transfer rating but different cache sizes. The current 2TB model is WD20EFPX, a 5,400 RPM CMR drive rated up to 180MB/s with 64MB cache.
Smaller capacities remain useful for mirrors, backup targets and entry NAS systems, but they can have a higher price per terabyte and consume bays that limit future expansion. Calculate three-to-five-year growth rather than sizing only for the files stored today.
When replacing an older 2TB or 4TB WD Red, do not assume the current Red Plus is identical. It may be a better CMR choice, but verify sector format, compatibility and the NAS replacement-size rule before starting a rebuild.
How Red Plus differs from plain WD Red and Red Pro
Plain WD Red has included device-managed SMR drives intended for lighter home and small-office workloads with idle time for background management. Western Digital recommends Red Plus or Red Pro CMR drives for more demanding environments, including ZFS workloads and sustained random writes during resilvering.
Red Pro is the higher tier, with a current 550TB-per-year workload rating, five-year warranty and unlimited-bay positioning. Red Plus remains the standard CMR NAS tier for up to eight bays and 180TB per year. A shopper should choose the tier first, then the capacity and exact model.
Do not identify the tier by color alone. Read the complete product name and model number. Marketplace search results can use “Red” as a broad keyword even when the actual item is Red Plus, Red Pro, an older Red or an accessory.
Use the model lookup as a first check, not the final check
The lookup recognizes the current model numbers in the cited data sheet and reports their capacity and profile. A model not found may be an older Red Plus revision, a Red Pro, a plain Red, a regional SKU or a typing error. It should not be labeled SMR or unsupported without official documentation.
After identifying the model, check the NAS vendor compatibility list. Compatibility can vary by NAS model, firmware and operating-system version. Synology policies in particular differ by product series and release year, so current vendor guidance matters.
For a marketplace purchase, verify condition and warranty. Manufacturer-recertified, seller-refurbished and used drives are not equivalent to new retail drives even when the model number is identical.
Buying and replacement checklist
Confirm the exact model number in the selected variation, not just in the page title. Check capacity, CMR status, RPM, cache, power, acoustics, condition and seller. Compare total array price and cost per usable terabyte after RAID.
For a new array, identical current models simplify management. For a replacement, verify the backup and follow the NAS repair procedure. Never assume RAID is a backup or replace several members at once without vendor instructions.
Keep the invoice, record serial numbers and firmware, run the recommended extended test and monitor early temperatures. The CMR model list helps avoid a product-selection mistake, but data protection still depends on backup and operating discipline.

Frequently asked questions
Are all current WD Red Plus drives CMR?
Yes. Every model in the cited current WD Red Plus data-sheet table is listed as CMR.
Is plain WD Red also all CMR?
No. Western Digital documents plain WD Red models using SMR, while Red Plus and Red Pro are the CMR families.
What are the current 8TB Red Plus models?
The cited current models are WD80EFPX and WD80EFZZ.
Why are there two 12TB Red Plus models?
They offer different performance and efficiency profiles. WD120EFGX is faster with more cache; WD120EFBX is quieter and lower-power.
Is a model missing from this list automatically SMR?
No. It may be an older CMR revision or another WD family. Check the official data sheet or support page for that exact model.
Can I use Red Plus with ZFS?
Western Digital identifies Red Plus and Red Pro CMR drives as the appropriate Red families for demanding environments including ZFS. Also verify NAS and controller compatibility.
