i just right clic the .rar & drag to folder where i want to extract to... it just extracts for rars anyhow
(winrar)

 

not sure what you're looking for, this maybe?

As far as I know to copy anything from A to B you need to buffer data into memory, pointers are needed.
Sure you can reduce buffer size but you can't skip it.
Even if you copy just a byte one by one it is stored in a memory address first.

 

You want to turn off disk write caching. That's easy - go to device manager, find your disk under "disks", click on it>properties>caching>turn off write cache. It's actually recommendable setting for audio computers - safer for data and uses less cpu. If you have only NVMes and SSDs this caching is a complete waste of time. You may find this setting turned off by default depending on your OS and disk types.

Cheers ArticStorm!

 

sorry to hijack thread by slightly offtopic comment, but what if NVME SSD actually leverages Host Memory Buffer (HMB) to access host system’s RAM for storing parts of the SSD’s mapping tables, as seen by for ex. WD Black SN770, is that completely independent from OS write caching?

 

It's a great question. Knowing how Windows, and Linux for that matter, handles caching - it does what's generally best for a certain type of disk automatically, I don't think it is possible to make anything worse or unstable by turning it off, if it is possible to turn it off at all. I don't have NVMe so I don't know how OSes handle these. It might be disabled by default and parts that need to be in RAM are handled differently.

What I said here is - I'm sure HMB caching is retained in any case. Sorry, I'm still a bit groggy from sleeping.

So I wonder if it will be possible to do anything at all. We'll see what ArticStorm says.

I've turned off write-caching on the large HDD where I keep vsti's (and their associated samples), new footage that needs to be cataloged, and storage for offline footage. Write caching on NVMe's and SSD's is kind of a wash because they are very fast to begin with and you really don't notice the speed difference that much. HDD's especially ones larger than, say 3TB, you will notice some speed increase with it turned off.

 

Teracopy.

 

@SineWave will turning off write caching create a problem for mechanical hard drives?

 

AFAIK Windows will disable or enable cache if it deems necessary for the disk in question.

Edit: worth noting that disabling cache is a placebo at best. The only reason to disable it is if you're afraid of data loss (and if it's on and never happened, no reason to be afraid now)

Cache will boost performance, but results in data loss in a crash or outage. If you also turn buffer flushing off, you might damage the filesystem. I would keep it as is, whatever is the current setting.

 

i had started a topic here titled "
fx cpu idling when it should be performing, winrar

- kind of a dumb way of saying it. cpu is @ 12 or so percent when extracting.
turns out my external usb hd is @ 100 percent thus limiting extraction

 

For media production of any kind at all, you want the easiest, most direct, and fastest path between data storage, RAM, and CPU/GPU that you can get. Unfortunately, they don't make NVMe's in 6-12+ TB sizes yet (if they did they most likely be out of anyone's price range). So for large cheap, fairly fast storage, the job still falls to HDD's.

 

I can't say Total Commander is faster without benchmarking it, but why it can be faster is because Total Commander doesn't use the same copy/move code from Windows Explorer. Instead of calling those native functions, it has its own. If it's faster or not in all cases, that can't be said without proper testing, but caching has not a lot to do with that. Windows will not cache unimportant files, and mostly important, it flushes its cache constantly to avoid data loss.

The issue with slow copying and garbage being left behind might be a symptom of another problem entirely.

 

Have you retested with teracopy? Does it leave the same garbage in RAM as the os file-mangler does? Would be interesting to find out.

I learned early on that microsoft's drive encryption and compression were junk and never ever used them in my some 20+ years using mickey-soft operating systems. The encryption service is one of the first things to be deleted on a new build.
