The three pools in this one system represent the three NAS systems I had before the consolidation. I have even put together some hardware just to test things out a time or two.įor a while I had three systems, all at once, at home but I am making some hardware changes right now and only one NAS is online. I made some mistakes along the way, learned some and I try to share some of those lessons learned experiences here in the forum. ![]() This is the 8th FreeNAS unit I have built for home. Think farmer's almanac, not encyclopedia.ģ.This one was built in 2018, but I reused the name from a previous build. That also means the chart below is not going to be 100% reliable. As I explained in that thread, I'm not prepared to commit the amount of time charting this data as I'm pretty sure it'll require. As such, I'll repeat: the data and information represented in this compendium is simply not complete. Recently /u/nfx45 posted such data with a specific call out about one serial number not working with his PSU and another 2 that did, even though all three are EMAZ drives. (confirmation about this thanks to /u/phaicm here)Ī lot of people in the comments have shared data about serial numbers, DCM's, and other such data in relation to the Easyshares as a whole but also trying to parse out info on the White Labels. This drive appears to be the white label version of the WD80EFZX, and from what I've been able to find thus far does not utilize the SATA 3.3 compliant power adapter so the 3.3v PIN issue can be ignored. The latest addition the Easystore family is the WD80EMZZ, another White Label. It seems this re-defined P3 spec was pushed on manufacturers by datacenter owners that wanted to save money from having a tech forced to manually pull and reseat a specific drive (reset) under limited cases of drive lockups. It was known that there could be legacy compatibility issues. At that time, the STA (SCSI Trade Association) researched the marketplace and determined that there were no conflicting legacy concerns. Q: When was this feature introduced on SAS HDDs?Ī: With the introduction of 12G SAS, a new SAS standard, SAS-3, redefined P3 (Pin 3) from “3.3V Power” to “POWER DISABLE”, i.e. The issue as the HGST document explains is that P3 (Pin 3) functionality was re-defined for SAS spec, and then later it was pushed into SATA Rev 3.3. Why is this a thing? Thanks to /u/breakr5 for calling out /u/MrKazador 's previous comments from here and breaking it down more clearly. Your psu/backplane may or may not be sata 3.3 compliant however. To quote /u/deebeeoh:Īlso of note the 3.3v issue is not so much an issue as a feature in the sata 3.3 spec. If you're using a ~10+ year old server, you might have problems, but you should probably realize that since you're using a ~10+ year old server. It mostly only affects older backplanes and power supplies, but some newer PSU's also may not support the newer pin design. The 3.3v pin "issue." These drives, when shucked, have been known to have problems with some SATA backplanes. The real point of discussion about these drives is the 3.3v pin. There's also a good chance that White Labels are Reds, just labelled differently for some models to mess with people shucking the drives and then reselling them. The white labels are probably drives sourced from a number of channels, tested to meet a minimum standard, and then labeled as WD80EMAZ where it fits. Supply for hard drives is not consistent. My theory: All of these theories are correct. Some people think these are relabeled HGST drives, refurb'ed Reds, Red's that didn't quite meet QA requirements, Red's with a missing feature or two. The general consensus is they're fine for most users as long as you're aware of what you're getting. There is what I'd call "some debate" over these drives. The -NEBB/WD80EMAZ "White Label" discussion WD80EMAZĘTB WD "White label", 256MB cache Seems identical to WD80EFAX, but potential problems for older devices you may plug in to.
