There's no backpeddling. Buy whatever you want and I hope it works out for you. Don't peddle your false facts about consumer drives being enterprise drives--they aren't.Keep backpedaling and read my posts more carefully, you'll eventually arrive at what I've been saying all along in this entire thread.
This is pretty common--a lot of the drive manufacturers have been using the word 'class' to define a particular category of performance. And without the exact spec sheets, you don't really know what the real rpm is. And does it matter? If a 7200rpm drive performs like a 5400rpm and they told you this a part of the marketing material, what's the problem?An Ars Technica article on the WD External drive RPM speed controversy: Western Digital is trying to redefine the word “RPM”
The article has links to the r/Datahoarder tests.
I have said the same thing about quality. And you need to make no mistake that these are consumer drives as the quality isn't enterprise aka 'real business'.This part is likely correct. They are the same drive in the sense of hardware parts, but not the same drive in the sense of quality.
However quality wise you should note that they are still better made than consumer grade drives, which uses cheaper parts and technology at the first place.
Warranty is not related at all. Warranty is a support service, and you can attach any period of warranty as you wish. For example, my ex company provides lifetime warranty for our servers with Seagate ES.3 drives. Of course, those drives are backed by only 5 year warranty, but we charge more and we self-warrant / self-insure. We replace the drives with brand new ones even after 7-8 years of purchase.
Another example is Seagate Exos drives shucked from expansions. They used to have warranty data on their website but they later revised them. New drives from RMA replacement also have different warranty (inheriting from the replaced drive).
Warranty cannot prove any of your points at all.
You are free to look it up. WD had admitted that they mislabeled some of the 7200RPM and claimed to correctly label them at near future.
The 8TB and above "5400 genuine red drive"s are also 7200 RPM drives.
In fact, WD never actually write "5400 RPM" on their drive specs. It has always been "5400 RPM Class", which has nothing to do with RPM at all.
It's like you buy a car that has "V6 power class" engine. Does it have a V6 engine? Maybe. It doesn't even need to have an engine. It can have an electric motor that produces V6-like power. Don't fool yourself with marketing terms and take that as "facts". You are not talking about "facts", you simply trust whatever they said. Which is reasonable because a regular consumer has no way to actually measure the RPM of a drive. It doesn't have a tachometer.
You really can't read--it's 5400 class, ie 'performance like 5400'. Does it matter what rpm it is moving if the job gets done within spec? No--that is why there are specs in the first place, for the job and the solution.The problem is someone on a forum would argue that a 7200RPM drive is 5400RPM.
The problem is someone compares a 7200RPM drive with a 5400RPM drive performance and claims the former must be running at 5400RPM because they are almost equally quick, but in fact it's the latter that's running at 7200RPM.
The problem is someone would prefer a "5400RPM class" drive because "5400RPM" produces less heat and has less vibration than a 7200RPM drive, and later find that's not the case.
You still don't see a problem? RPM is rev per minute, period. If you wanna talk about performance, we used to have WD black = top performance, green = least performance, etc, and that is the correct way to market. RPM is not about performance alone. We had 10k and 15k RPM drives in the past, and they perform worse than those WD Red 5400RPM drives. Should they be renamed to 1k and 1.5k RPM drives respectively? How about SSD? They should be advertised as 250000RPM or something? How about turkey? They should be advertised as chicken class or something?
I could never understand that people are ok with vendors deliberately misleading consumers. /rant

RPM define how performant (sequential AND random io) hdds are when the platters have the same storage densityYou know how fast a 15k velociraptor drive from a decade ago performs today? Even today's 5400rpm drives are faster. RPM means nothing these days except as a unofficial rating system.
That's great. I'll be getting some on the next drop I guess.The TLER setting change is retained on reboots if anyone was wondering. I upgraded to U3 TrueNAS last night and it's still 7 seconds on all drives. So that (non?)mystery is solved!
Is there a good summary or guide to TLER? I’m using 24x shucked 8TB disks, never changed anything or noticed any issuesThe TLER setting change is retained on reboots if anyone was wondering. I upgraded to U3 TrueNAS last night and it's still 7 seconds on all drives. So that (non?)mystery is solved!
It's already here...Better buy whatever you can now before chia mining picks up. Hdd/ssd are going to get really expensive in the near future
Agree. Last I checked the network was at 600PB and growing fast.Better buy whatever you can now before chia mining picks up. Hdd/ssd are going to get really expensive in the near future
