my setup:
- dual socket epyc 7551 (total of 64 cores / 128 threads)
- 16 * 32 GB ecc-reg ddr4 2666 mhz Ram ( total of 512 GB)
- HBA card is LSI 9400-16i
- backplane is gooxi 36 v1.0 (with sas expander)
- 24 bay SAS-2 internal hdd ports
- backplane and LSI are connected with 2 cables (i think to get aggregated and higher transfer speed)
- 10 TB sata-600 7200 rpm seagate iron wolf pro
- 4* Dell 900 GB SAS-2 10k rpm (configured as STRIPED = raid 0 volume under Windows 10 enterprise)
now the odd thing.....
......when transfering chia-plot files from 4* dell raid0 to 10 tb sata-600 (size of 101 gb big files) under Windows 10 i get transfer speed of 30 MB/s
..... when transfering the same file from 4* dell raid0 to 10 TB sata-600 under Ubuntu 20.04 i get transfer speed of 130 MB/s
in Ubuntu 20.04 all drives are mounted as NTFS paritions, using the latest ntfs-3g available from ubuntu repositories.
one would expect on native platform (Windows 10 and NTFS) to get faster transfer speed then in non-native platform (i.e. NTFS in Ubuntu)......this is odd....
does anyone have any explanations to these odd difference between Windows and Ubuntu, regarding transfer speed?
i dont care about chia plots and speeds of it, but i am very curious how this situation can be explained.
