Review: A good hard drive - Arrived very quickly. Being used in an enclosure as an external backup drive. 4TB version. Packaging was ok (just cardboard rather than foam or bubble wrap) but drive seems fine. Formatted no problem and drive scan shows no errors. Only problem was my older enclosure (IcyBox - over esata) was ok with the previous 2TB drive but couldn't cope with the new 4TB one (both WD) - formatting errors. New enclosure (RSHTech - over USB 3) is fine with it. Very quiet and only slightly warm in its enclosure. Pleased so far.
Review: Rock solid NAS drive - Purchased a pair of these drives. Have never looked back. Reliable and that's the way it should be. Using the drives in a SOHO setup for photography. No issues This is not the first time for me to set up a SOHO NAS but it has been the most stress free using these drives Deserves all five stars and more

## Questions & Answers

**Q: How much cache does this drive have?**
A: UPDATE: Just checked with WD website and it seems that they have updated these drives. The more recent version of the Red Plus is the WD40EFZX model which does indeed have 128mb cache. The older WD40EFRX had only 16mb of cache. Both drives use CMR technology (not the crap SMR technology) so both are equally good and equally suitable for NAS drive. Just check that the model number is WD40EFZX and you'll be fine. Oh and don't get hung up about the cache if you're planning to use these drives in a NAS because you're unlikely to see any real increase in performance.

**Q: Where did you get the new drives since they have been out of production for several years? are these repaired drives?**
A: I purchased them from Amazon.

**Q: Are these any good for storing & streaming 4k movies for plex ?**
A: That’s exactly what I use it for in a Qnap NAS. Works great.

**Q: Has this 128MB cache or not? Details are lacking, can't purchase on a probability!!**
A: Yes it has
