Read and Write drives

Description of problem or question:

I am currently building a new PC with an AMD Ryzen 9 3900X. I have been using Handbrake for years. What a great program.
My question is that I want one drive to store my encoding files and one drive to write the results to. Which drive [read/write] should be the faster NVMe drive?


Steps to reproduce the problem (If Applicable):




HandBrake version (e.g., 1.0.0):

1.3.1


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Windows 10


HandBrake Activity Log ***required*** (see How-to get an activity log)

Code: Select all

Please replace this text with the contents of your log file between the two code tags - OR -  provide a pastebin URL in place of these 3 lines.

Unless you're dealing with raw uncompressed video source files, it doesn't matter, even a mechanical hard drive will suffice, difference will be imperceptible. The only thing that could be a bottleneck is USB 2 (not USB 3) :D

To echo Rodeo, drive throughput is not an issue in either direction for most video encoding.
That said, concentrate on your CPU first, and GPU second.

Thanks I am about to order a new PC with AMD RYZEN R9 3900X and MSI GeForce RTX 2070 Ventus GP Graphics Card plus PCIe 4.0 SSDs so I should be OK

Yes, you should. Try keeping render threads around 8 to maximize efficiency and minimize overhead.

I burn all my videos to DVD so when encoding I select a bitrate to fit the optimum amount of video per DVD. For 1080p I usually choose between 2500 and 3000 kbps to get say 4 x 44 minute videos per DVD. The picture then looks great [to me] on a 75" 4k TV. I am sorry but I have absolutely no idea what "keeping render threads to around 8 to maximize efficiency and minimize overhead" means.
My current system is pretty good but I just want to increase my framerates while keeping video quality up. With my first Core i7 system you could not do anything else while encoding.
My new system includes 3 SATA and 2 NMVe drives with the main encoding power as follows...
AMD RYZEN R9 3900X, 12C 24T, 70MB CACHE, 105W TDP
GIGABYTE X570 AORUS PRO WIFI AMD MOTHERBOARD
G.Skill Trident Z Neo 32GB (2x16GB) DDR4 3600MHz Desktop RAM
MSI GeForce RTX 2070 Ventus GP Graphics Card
Corsair Force MP600 1TB PCIe Gen4 M.2 NVME SSD

While my current system is...
Intel Core i7 7700 3.6Ghz 7th Gen
Gigabyte GT1070 windforce OC 8GB
Gigabyte GA Z270 Gaming ATX mother board
Corsair 32 GB DDR4 2400 RAM
Samsung 960 EVO 1TB M.2 NVMe SSD MZ V6E1T0BW

Unless you are having specific issues don’t worry about the threads, the encoder is much better at dealing with that than musicvid.
