If it takes 46 pages to explain, then I don't think it does anything for <3TB drives
While I agree with your text (in BOLD), I don't understand the purpose of your LINK, so I just QUOTEd the appropriate section from @ggieseke's post, which is what I believe @CIR-Engineering was referring to.
If the requirement is you open the door in 10 seconds and you place the person opening the door next to the door in one case and in the other case you place them at the top of the stairs, the door will still open within 10 seconds.
So yes, the guy on the other side of the door waiting to get in will still have the door opened within 10 seconds.
However in one case, the person opening the door will get more wear and tear.
When I first got my Seagate 4TB SMR drives I copied over a few hundred GBs to it with the PC to test it out. It had very fast transfer rates and provided consistent speeds. But it also had firmware 0001.
I've read that the WD 4TB drive might use a combination of SMR and PMR. And maybe that is what my 0001 Seagate drive does too. no idea. But that was back in October 2015 when I first got those 4TB drives and tested them.
I've used msfr on every drive in every TiVo I've used in the past few years. From 500GB up to 5TB.
No idea if the version that works on 2TB and lower drives is out yet. I had to send a PM to get the version that worked with 2TB and lower drives. But I've had no issues with the 500GB drives I've used msfr on.
Glad you got a response. I haven't hear back from my friend yet at WD. I kinda figured the drive had to be.
Well if it's fully a PMR drive then that should be the first choice and also the largest PMR drive available to use.
Although it seems to be expensive. More than the already expensive 3TB WD drive is.
Yeah, I'm pretty stoked about this upgrade.
My Premiere Series 4 with a 4TB WD Purple has been an absolute joy.
Ok. My WD WD40NPZZ is in, and apparently ok (fingers crossed).
MFS Reformatter under Windows 10 was ridiculously fast - I attached it directly to the MotherBoard. Is it normal to take less than a minute ?
I watched - pretty easy.
I used a TEKTON 2830 Everybit https://www.amazon.com/TEKTON-2830-Everybit-Precision-Electronic/dp/B009MKGRQA/ref=pd_lpo_vtph_469_tr_t_2?_encoding=UTF8&psc=1&refRID=EMPY8XK76Q84W5NCPTWS which costs under $10 , and includes a Star Security Bit and a Spudger Mini-Pry Bar as well.
TIP: Get yourself an old Credit Card and cut it up. Every time you release a tab, place a strip of Credit Card in place to hold it open. Makes life easy.
I opened the case and closed it without breaking a single tab !
4TB = 4399 SD Hours ?
I have a 2T @ 2177, so about right
MFSr is really fast and easy.
Mine says 4401 hours ;-)
I guess a 1% or 2% difference is acceptable.
Yes. It took less than a minute on my 8TB WD Easy Store drive that I used in my Romio OTA.
Quite a difference from the Linux Boot CD I used with my Premiere Series 4 units !
Of course I was copying files then.
Yet my WD 4TB Purple on my Premiere Series 4 states 5607 SD hours.
That's more than 10% more hours in the Premiere.
The number of hours is nothing more than a guess and TiVo may not be using the same estimated size per hour in different models for some reason.
Pulled my WD40NPZZ 4TB drive yesterday and ran an extended SMART test in my Linux machine to check on it... all good so far. Also, the seller on eBay central_valley_computer_parts_inc has the exact 3TB hard drives that are used in the BOLT+ right now. Item number 272309193026.
I know that jpeg is a compression algorithm, and that pictures that have the same frame size, can be stored with vastly different byte counts. That is because some pics are simpler than others.
For instance, a 600X800 pixel of the Mona Lisa would be far more complex than a 600X800 black, featureless square.
So while a storage device could hold untold thousands (millions), of pics that are featureless black squares, it would hold far less complex Mona Lisa pics.
So any claim to number of pics that can be stored will always be an estimate.
I suspect the same principle applies to hours of Video. An hour of simple videos, e.i., early Hanna Barbera cartoons, would take up far less space in Bytes than an hour of The Last Jedi.
Does this explain the differences in Video Hour Capacity that are claimed ?
