Re: CMR or SMR?
I don't really have a preference.....I've never paid much attention when looking at NAS or NVR/DVR HDD's.<--- Badcaps.net Founder

Re: CMR or SMR?
If given a choice, why would anyone prefer SMR?
Unless you mean, taking also capacity into consideration.Comment

Re: CMR or SMR?
I have an SMR drive in my main system. It's only a data drive (no software), so speed doesn't matter that much. It's one of those drives that wasn't advertised as an SMR drive, but it's good enough for what I'm doing.Comment

Re: CMR or SMR?
Whatever I got the better deal on. Not sure what my server backup drive is... 4TB iron wolf NAS drive I got at a pawn shop for virtually free and then RMA'd since it was still under warranty. The main drives are CMR's for sure... desktop 1 platter 7200RPM 250GB seagates (15 of them). OS drive is a CMR Seagate 7200 80GB (smallest SATA drive I've ever seen, only good use for it).sigpic

Re: CMR or SMR?
CMR. Unless managed properly, you can expect problems with SMR drives.Useful conversions. I don't "speak" imperial. Please use metric, if you want to address me.
1km=1000m=100000cm, 1inch=2.54cm, 1mile=1609.344meters, 1ft=30.48cm 1gal(US)=3.785liters, 1lb=453grams, 1oz=28.34gramsComment

Re: CMR or SMR?
I did a lot of research before I bought two new 6GB NAS drives. Nobody has anything positive to say about SMR's performance or longevity. Price and capacity seem to be its main advantages but, if you're looking at a once-every-five-years purchase like a NAS upgrade, you might as well shell out a few extra bucks for the more reliable solution. Rebuilding those drives is a pain and takes forever.Comment

Re: CMR or SMR?
Yep. 24 hours minimum to write 4TB to my 4TB external drive (which is SMR), and at least 18 hours to immediately read it all back and write to to a CMR drive.
Meanwhile, I can move 4TB from one CMR drive to another in 10 hours.Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

Re: CMR or SMR?
Meh, where's the option for longitudinal recording?!
(OK, I suppose that still falls under CMR.
)
My 80 GB Samsung-made Samsung PATA/IDE HDD is still happily clunking away as we speak here.

Re: CMR or SMR?
That's no surprise, it was made before Samsung exited the HDD market and basically sold the whole division to Seagate. I suffered a major data loss event thanks to a 2014-era Samsung external drive, which was nothing more than a rebadged Seagate drive.Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

I've been using a digital microscope and would like to purchase a nice stereo scope. Which model(s) do you prefer? Would like to be under $700 USD.

Ok, I was given this Mac Pro (early 2009) 4,1 a week or so ago.... Single socket Bloomfield quad core @ 2.66GHz and 8gb RAM.
I found a dual socket CPU card that is coming with a pair of CPU's and 32gb RAM for it (hasn't arrived yet)....and want to play around with this thing a little....but here the first problem. It originally came with 10.11 'El Capitan', which isn't bootable...OS long gone. I got Mint 20.3 running great on it and windows as well. Under Windows, the only thing I couldn't seem to get working is the bluetooth (worked fine on Linux).....but... -
Happy New Year to all,
I have a 2012 macbook pro 13 motherboard 820-3115-B with the following problem (due to water damage): it starts up normally but does not go on screen. I checked the LVDS CONNECTOR line and found the following damaged components:
L9004: FERR-120-OHM-1.5A 0402-LF
L9008: 120-OHM-0.3A-EMI 0402-LF
In the repair I would prefer to replace the adjacent capacitors as well: C9010 and C9015: 0.001UF 10% 50V X7R-CERM 0402.
On Mouser I tracked down the following components respectively for:
L9004 with the following... -
I read article after article in bed last night and It's still confusing on what's good, what's bad, what definitely needs cleaning afterwards, etc.
I have a spool of MG Chem 63/37 RA 2.2% and that's pretty much my go to for anything I care about. I have some cheap chinese 63/37 as well that I use when priming a joint for suction/removal or stuff I care less about.
I like .8 and .6mm thickness. Anything thinner and I feel like I'd have to feed a ton more in. -
