My CPU and GPU plot time tests (based on 5TB drive)
-
@vier23 Thanks, that's what I'm trying to figure out too. Others have said it's my CPU, number of threads I use, RAM, etc. I'm not sure. Granted the Seagates are bit on the slower side, but still 5 days is nuts. Once I have time and more drives, I'll do another CPU optimized plot test.
I did the GPU plot because I got impatient, and wanted to get up and running. lol I know some people with dual Xeons and 256GB of RAM, can do CPU plotting with 25TB, and get it done in +-24hours, which is crazy fast.

@Vneck said in My CPU and GPU plot time tests (based on 5TB drive):
RECAP:
CPU plot: 5 and 1/2ish days
GPU plot: 20ish hours.Thanks for your test, but like mentioned before, you can not compare this two results directly, as the CPU plot is already optimized. So for me the result should look like:
CPU plot (optimized): 5 and 1/2ish days
GPU plot: 20ish hours. (buffered mode)
GPU plot (optimized): ~1 day 11,5 hours (2nd drive needed, ~15,5h optimize @90mb/s)GPU plot (optimized): running ... (direct mode)
I'm not sure if the optimizer is really that fast ... could also be double time :-)

Hi Superfriends. I bought another 5TB drive, as I'm still using the other 5TB plotted earlier (non-optimized), and have started a new GPU Direct "optimized" plot. I'll let you know what times I get.
@blago thanks for the settings tip.

@Vneck SMR drives are a PITA to plot, they mine fine, but plotting is slow.
-
Yup, finding that out the hard way. lol Are there other external drives you can recommend? Trying to avoid buying bare drives and then buying a separate enclosure. I used to be a big WD fan back in the day, but I haven't kept up on the latest tech since I left desktop support.

@Vneck Check this thread: https://forums.burst-team.us/topic/4290/wd-external-hdd/
More recommendations are: Toshiba and HGST.
Work around SMRs is to plot on a normal (faster) drive and copy the plot to SMR drive.

@rnahlawi Yes I'm thinking the same. I'm gonna get a WD drive next and do another test. If the WD drive is faster, I'll continue that route.
