By the way. Did anyone try to use a large sd-card as storage ?
I meant 256-512GB. In my logic it must decrease power consumption when keeping the same IO performance as external ssd connected through USB.
- razemio 4y agoI am uncertain if USB can be a bottleneck there, but if I am not mistaken, SSDs offer better (more?) cache. This dramatically reduces time needed for non-sequential read/write operations.
- rmykhajliw 4y agoUSB - 30Mbyte/sec theoretically for RPI, but in reality somewhere around 20Mbyte/sec SD cards - class 10 tested on RPI show the same performance 21-27Mbyte/sec So the issue mostly in throughput performance of the interface
