Is there any significant difference of mining performance between 5400rpm hd and ssd if they are of the same capacity?

only the fact that you will never get ROI with SSD, so no need to put your text in supersize  

[Yanakitu Tenatako]

Here is a structure of a 4Tb drive:

I made plots with GPUPlotGenerator 3.0.0:

gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101000000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101025000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101050000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101075000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101100000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101125000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101150000000 2048000 8192
gpuplotgenerator.exe generate "D:\plots" 3000*************** 10101175000000  901120 8192

I assume stagger size is 8192 ?

It takes from 130 to 200 seconds for reading with Blago miner.
I have tried with 32Gb ram, does not makes any difference.

With 8Gb ram it wont even read plots. Miner is breaking system apart.

Not really as long as HDD is being read in time without skipping the blocks. Better to buy more space instead. Big capacity USB2 devices might be too slow though. Some 5400 rpm hdds are faster than 7k btw.

[Yanakitu Tenatako]

Using Blago mi ner, for 26Tb plot, it takes 200 seconds (more or less) and CPU is @ 100% use.
Having 16Gb RAM.

IS it OK? I think it is long time.

11,5 Tb, 26 sec, AMD FX 6300, 16Gb RAM

Hmmm..... Must be than a CPU making that difference? I am using A4-7300.
Will get better one for testing. Hdds are fastest I could get. WD purple.

I cannot run latest version of your miner, it is crashing.

My 2nd rig have 8Gb RAM...
You can merge plots for fast reading. Use dcct's "optimizer", or https://burstforum.com/index.php?threads/plot-optimizer-v1-5-j6jq.268/

PM me logs (if you not solo mode)

Generally, stagger size is ok?

Mining process isn't CPU-intensive.

Blago's miner tries to read all files in parallel. You'll have to merge them into one file per HDD or use a different miner which reads them sequentially.
Sorry, not true.

Blago gave an example on his picture, you can read he is having 8-11 files per hdd.
Why then I an getting dofferent woth same structure?
He is not using 1 file per hdd also.

While reading plots CPU is locked at 100% as long as reading goeas on, after that, goes to almost 0%.
So, maybe reading of HDD actually IS CPU sensitive?

Just a thought....

I love it! Nice work! Can I post it places and just give you credit?

This is very well done and good subliminal

Really, really nice
But I would put Burst on the left and other cryptos on the right so people start looking at the image from the most important.

[majere]

Sorry, I confused Blago's miner with Uray's. You are right, it spawns one thread per folder and reads files sequentially.

Sure. No credit is neccessary, it's public domain. I'm not the author, but he reads this forum.

Is there any significant difference of mining performance between 5400rpm hd and ssd if they are of the same capacity?

In theory yes but currently no. The bottleneck is not the hard drive or SSD speed its more of the RAM and CPU when plotting and mining (although with mining the requirements are significantly lower). Usb 2 may see less performance but a usb3 hard drive or any internal hard drive will never be the bottleneck

This is true for Western Audiences.

That's awesome, majere.  Sent you 20K burst.

Will get better one for testing. Hdds are fastest I could get. WD purple.

WD Blacks > WD purples.

Thank you! The image is not mine, but the author told me he much appreciates the donation.

WD Blacks > WD purples.

WD purples should be very fast. Quoting specs:
6 tb - 175 MB/s
5 tb - 170 MB/s
4 tb - 150 MB/s
3 tb - 145 MB/s
2 tb - 145 MB/s
1 tb - 110 MB/s

WD black:
4 tb - 171 MB/s or 154 MB/s depending on model
3 tb - 168 MB/s or 154 MB/s
2 tb - 164 MB/s
1 tb - 150 MB/s or 126 MB/s (I have the second one)

WD red 4tb - 150 MB/s.

My 1 TB WD black vibrates like crazy, I wouldn't recommend it to anyone. Newer models may be better, I don't know. Also blacks are desktop drives. Reds or purples are probably better for mining.

WD Blacks > WD purples.

Yes, yes, I know, I just could not get 60 pcs of black WD in descent time.
So I choose purple over red ones. More intuition than knowledge.

I will try with different hardware, but I have SATA3 mb, SATA3 hdds, SATA3 cables... really nice case and cooling.
Will post my pictures soon, but I am a bit frustrated with results.
Would really really be thankful for setup help.

BTW. Stack of 8 pcs of these purple ones is noiseless. Like not working Temps also ok, but I got Sunon fans just for the case...

Neither firefox nor chrome seem to like the chart.js script on uray's US pool, in both browsers I need to stop the script but it will restart with every new block. Anyone else have the same problem..?
