I’m in the process of building a new rig for DL, and I’d like to know whether someone has tried to benchmark the performance of NVMe drives versus regular sata ssds during the training process, particularly with large datasets.
I’m asking this since the minibatches have to be fed to the GPU(s) from the hard drive, so I assume (perhaps incorrectly?) that a relatively slow ssd could be a significant bottleneck no matter the amount of ram, and/or how powerful your GPU could be.
Thanks.
