Determining the slowest point in network data transfers
Determining the slowest point in network data transfers
It seems like the issue might be with the 660p and write caching. Consider switching to a different SSD for that device.
I thought similarly, but with the original SSD I still face the same issue (Toshiba THNSNJ128G8NY), and I encounter problems with small files and occasionally at the start of file transfers before caching fails. I don’t really require high sustained speeds for transfers; it’s mainly for video editing where all cache files are stored on network USB drives. Finally, regarding speed tests on USB drives connected to X4S, both read and write were around 30-35MBps, so I suspect the limitation isn’t the 660p.
The USB and network drivers will store some information in caching areas. The Intel 660p allocates part of its storage in SLC mode, with capacity ranging from about 6 GB to up to roughly 70 GB for the 500 GB model, as detailed in this review: https://www.legitreviews.com/intel-ssd-6...h_207025/6. When writing to the SLC section, performance remains quick, but speed drops once it fills and transitions to regular flash memory. In the review’s graphs you’ll see this trend. With USB drives, latency becomes an issue—small transfers take longer as commands move between controller and drive. Larger files reduce the impact of delays.
