Troubleshooting • Re: RPi 4 NVME over Network transfer speed issue

Problem solved
All data was saved from the HDD, and the partition from NTFS was converted to EXT4. Now the speed of working with SMB over the network is close to maximum - about 1Gb/s. At the same time, HDD is still working in Quirk
It turns out that Raspberry works very poorly with NTFS partitions. The speed is greatly reduced. This is confirmed by many tests on the forum. When working with EXT4 via a USB-SATA adapter, the speed, although far from maximum, is sufficient for a 1Gb/s network.
I couldn’t solve the problem any other way so that NTFS would work :(

Code:

sudo hdparm -Tt --direct /dev/sda/dev/sda: Timing O_DIRECT cached reads:   544 MB in  2.00 seconds = 271.83 MB/sec Timing O_DIRECT disk reads: 450 MB in  3.01 seconds = 149.34 MB/sec

Code:

dd if=/dev/zero of=test.tst bs=16M count=50 oflag=nocache50+0 records in50+0 records out838860800 bytes (839 MB, 800 MiB) copied, 13,1277 s, 63,9 MB/sdd if=test.tst of=/dev/null bs=16M count=50 oflag=nocache50+0 records in50+0 records out838860800 bytes (839 MB, 800 MiB) copied, 8,46451 s, 99,1 MB/s
The DD results are a little strange. This is because the write speed on HDD differs in different places: about 60MB/s on internal tracks and up to 120MB/s on external ones
