So my old Cloud Mirror gen 1 has finally had a disk fail. I currently have two 4TB drives model WD RED WD40EFRX. Now that I have to replace one of them, do I have to buy the EXACT same make and model, or can I buy a newer version of the 4TB (for instance the WD40EFAX)? Sorry I’m not a super tech savvy person and this drive replacement issues is a major stressor LOL.
Hello,
Please refer to the following KBA article to find the compatible hard drive: https://support-en.wd.com/app/products/product-detail/p/136#WD_compatibility
So. . . the “Red” product line has changed since the MyClouds went off of store shelves.
The lower end of the “red” line are now SMR drives.
I would not fool with that and jump to the 5400 rpm CMR lines, which is a feature of the “red plus” line of WD nas drives. I don’t think you really NEED to use WD branded drives. I would feel comfortable with any 5400 or 7200RPM CMR drive that is rated for NAS service
I have heard that on OS3, you could put 10 or 12TB drives into the MyCloud Mirrors. . . .although they were not sold that way. With OS5, drive sizes above 8TB are no longer supported (gah)
(I suspect very large drives will cause problems with the indexing process. . .the MyCloud mirrors are questionable in terms of their ability to effectively index).
Curious whether anyone can confirm whether you can upgrade to 10TB or 12TB drives with OS5. Looking to upgrade my 4TB drives as I’ve run out of space. Thanks!!
Hi, I know this is an old question, but I have the same situation. How did you solve it? Did the new version of the drive work for you?
The mycloud mirror is a very old device at this point. I would highly recommend a newer 2 bay NAS as replacement. (The EX2 Ultra is a nice unit; but is OLD tech. . . .like, 5+ years old. . . .avoid the WD Home line like the plague)
I have heard that OS5 in a mycloud mirror will not support more than an 8TB drive (this is a software “feature”, not a hardware problem. Others have put larger drives in the old boxes when running OS/3).
Hi, thanks for your answer. I use this My Cloud Mirror gen 2 only for private pictures or movies. And it works fine for me for the last years. I don’t need a bigger hdd. I have an EX2 ultra too for private documents.
So my question was actually related to the first question in this topic. If I can replace the one old 4TB hdd (WD40EFRX) with a new model (WD40EFPX), but still 4TB?
It should work in general.
The new model. . .the EFPX… . .is that a ssd? That is giving me pause.
I would try to stick to spinning drive. Just make sure they are CMR, and not SMR.
