New(but old external HD) formating/plotting info

Im putting this here for some general info
im about to plot a new drive , i seen somewhere to plot but so it has little impact on your cpu useage , were was that info , i seen it just cant find it, im sure @haitch posted it somewhere
also formating it what is best
NTFS or exfat?
and format
unit size
4096 bytes
8192 bytes
16 kilo
32 kilo
64 kilobytes ?and also quick format or not ??
thanks in advance

I don't think it affect much, let see what other thinking about.
-
All my farm drives are NTFS, 64k and quick format is fine. I plot 100GB files on the drive to get each completed plot file mining ASAP, rather than waiting for a huge full drive file to finish. Also, if something goes wrong with a file, you can just delete the offending 100GB file instead of 2TB, 4TB or 8TB full drive files.
-
@rds I think I might have to give this a try rather than doing the bulk drive. I'm using 3TB drives with 3 cores and its taking about 3 days.... that's a lot of 3's....

ok kool so just do lots of little 100 GB files then , thanks for the info mate appreciated !!

Well go me hands on 4 5TB seagate externals $130 Aussie each , all hubbed up and let the plotting begin!!
-
Wish there was a way to plot multiple drives at once without needing to use up another pc.

@DougLife Me too but it is what it is !!

@Bitdv I think 100GB is too small. I plot 1TB files and with a decent i7 PC with 32Gb of RAM I can do 5TB in 24 Hours.

@RichBC I have AMD FX-8350 Processor 8 Core, wraith cooled 32 gb ram so will see how it pans out
-
@Bitdv Thing to do is get plotting and see how it goes, as with everything you learn quickly. Starting from scratch I would now uses xplotter, but here I still use wplotgenerator and optimizer as I am used to them.

@Bitdv NTFS, 64KB Block size and one large file instead of lots of smaller ones.
xplotter to do a drive at a time, gpuplotgenerator to do drives in parallel.

How about the aspect of files generating errors, the ability to just delete an offending 100GB file compared to re-plotting a 5TB file?
Just me thinking along Bitdv's idea
-
I've got a laptop with i7 6700HQ cpu and 32 GB of ram and plotting 400 GB file at a time with Xploter is fine to me :)
@Bitdv if you use Xploter do not forget to run it as administrator as it goes faster.

@delords it'll be much slower to mine 50 100GB files rather than one optimized 5TB file. Yes it's painful if you have a plotting error, but in the long term the pain is worth it for mining performance. Remember, you plot once, but mine forever.

Thanks, Noted

Which is why I have settled on the compromise of a 1TB file size. Very little hit on reading and not too much of a pain if the plotting goes wrong. That said I know what I am doing now and 5TB would probably be fine. At least with wplotgenerator as it is very good at restarting if the PC reboots etc. Not sure if xplotter does this?
-
@RichBC Yep, xplotter can be stopped and resumed
-
How can one be sure of the next starting nonce without overlapping when trying to resume xplotter after a fail or system restart?
-
@delords wplotgenerator checks and sorts this automatically. I assume xplotter does the same?
