      @comet424 like mitu said at the bottom of the forum don’t use ntfs. I haven’t actually put everything into action yet but I did a lot of research and I do remember seeing not to use that format as it will affect performance.

        ah ok ill check out link

        i did try formating the 2TB in Fat in my Unraid Box but it formated but it was unmountable formatting FAT wouldnt format 2TB right

        and then i googleed.. and it said Linux 5 and up has ntfs full support doesnt retropie use Linux 5+?

        so how can i format it then in retropie to get the 2TB to see Fat? or would be better ExFat? as i was able to mount that in Unraid ExFat for 2tb

        do you guys fill a 2TB? or find 1TB big enough?

        i didnt know from that link kodi was to watch pirated videos .. i seen i on my unraid has the kodi /LibreElece/OpenElece
        learn something new everyday

        and didnt know bios's and such not legal either..

          i ran the dd program on the bottom of that forum

          pi@retropie:~ $ dd if=/dev/zero of=./largefile bs=1M count=1024
          1024+0 records in
          1024+0 records out
          1073741824 bytes (1.1 GB, 1.0 GiB) copied, 45.0954 s, 23.8 MB/s
          
          pi@retropie:~ $ sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"
          pi@retropie:~ $ dd if=./largefile of=/dev/null bs=4k
          262144+0 records in
          262144+0 records out
          1073741824 bytes (1.1 GB, 1.0 GiB) copied, 25.6095 s, 41.9 MB/s
          pi@retropie:~ $
          

          and i running a WD 2tb SSD speeds up to what 550mb/s

          but thats why i went ntfs.. cuz when i googled linux should have full support in kernel for ntfs least thats what i read unless thats a different version?

            Can you please provide a source link ? Not sure what Linux 5 is suppose to mean.

            You can format it on a PC with ExFat or from Linux with the command line mkfs.exfat command.

            sudo apt -y install exfat-utils
            sudo mkfs.exfat /dev/sda1
            

            Warning - formatting will erase all existing data on the disk !

              wont let me post correctly
              https://www.theregister.com/2021/10/13/how_ntfs_finally_made_it/#:~:text=Starting with the Linux 5.15,FAT)%20file%20system%20across%20Windows.

              here it says as if linux 5.5 version ntfs fully supported
              but maybe fully supported and getting retropie to access at full speed 2 different things

              Starting with the Linux 5.15 kernel, NTFS is finally being fully supported in Linux. This journey hasn't been easy.
              
              Microsoft introduced NTFS, a proprietary – naturally – journaling file system in Windows NT 3.1 in 1993. From there, it replaced 1977's File Allocation Table (FAT) file system across Windows.
              
              
              

              https://www.zdnet.com/article/linux-boosts-microsoft-ntfs-support-as-linus-torvalds-complains-about-github-merges/

              Linux creator Linus Torvalds has agreed to include Paragon Software's NTFS3 kernel driver, giving the Linux kernel 5.15 release improved support for Microsoft's NTFS file system. But he also had some process and security lessons to offer developers about how to code submissions to the kernel should be made.
              

              i did see in another link
              to use ntfs-3g

              for for the fstab
              would that fix things? adding -3g

                i guess retropie doesnt fully support ntfs

                above says Linux 5.15 kernal is fully supported

                but when i logged into retropie

                it only runs 5.10.63 so its not fully supported yet.. i guess once retropie upgrades to 5.15 maybe then ntfs gets the fully speeds

                i formated to exfat but it didnt take

                  extfat just wouldnt work now is this fat or fat32?

                  so copying is even worse.. now it only copies 2-5mbs/s

                    i did google and found a different format

                    pi@retropie:~ $ sudo mkfs.vfat -F 32 /dev/sda1
                    

                    now i got 5-10mb/s but no where near 80mbs whats going on? its it writting to the SD card first then the SSD?
                    as its supposed to write directly to the SSD

                    and i dont know how to get the testing of the dd or the hdparm command for the sda1

                    is it maybe retropie cant hand 2TB at the full usb 3.0 speeds? as i didnt have issue with the same brand SSD just at a 250 and 500mbs but now i jumped to a 2TB i get these extreme slow speeds..

                    and i dont know linux good enough to trouble shoot things

                      @comet424 said in how do you get faster write speeds to SSD only getting 24mb/s:

                      i formated to exfat but it didnt take
                      [...]

                      You've run the correct command, but your next df commands don't show that the newly formatted partition is mounted.

                      so i dont have that hdparm program not sure how to install it

                      You can install it with sudo apt install hdparm.

                      i did get it to format and mount using sudo mkfs.fat
                      extfat just wouldnt work now is this fat or fat32?

                      It's neither, exfat is another type of filesystem, just like fat or vfat (which is Linux name for FAT32).

                      I'm not really sure how you're testing, your df commands don't show the /dev/sda1 partition being mounted so you may actually be testing just the sdcard.

                      is it maybe retropie cant hand 2TB at the full usb 3.0 speeds? as i didnt have issue with the same brand SSD just at a 250 and 500mbs but now i jumped to a 2TB i get these extreme slow speeds.

                      It can handle it fine, that's not the issue here - is the filesystem used. Use exfat instead of ntfs and you should get better performance.

                        ill re ty again and the test i did was on the bottom of the forum page

                        i ran

                        pi@retropie:~ $ sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"
                        pi@retropie:~ $ dd if=./largefile of=/dev/null bs=4k
                        

                        and ran

                        dd if=/dev/zero of=./largefile bs=1M count=1024
                        

                        so i installed it and ran

                        pi@retropie:~ $ sudo hdparm -Tt /dev/sda1
                        
                        /dev/sda1:
                         Timing cached reads:   1588 MB in  2.00 seconds = 793.80 MB/sec
                         Timing buffered disk reads: 882 MB in  3.00 seconds = 293.62 MB/sec
                        

                        so for doing the exfat how do i change that for the fstab? as it wouldnt mount or if it did it was media/usb0

                        pi@retropie:~ $ df -h -T

                        this above formated for fat 32 and i getting copy speeds of 5-10mbs

                        but when i had ntfs it was least 25 so i dont get it ):

                          Did you try to use the fstab line that you previously posted ?

                          /dev/sda1  /home/pi/RetroPie       exfat   nofail,user,uid=pi,gid=pi 0     2
                          

                          When you test using dd, make sure you're using an output file that's on the external disc:

                          dd if=/dev/urandom of=/home/pi/RetroPie/test.file bs=1M count=1024

                            for the fstab i tried "exfat" "exfat4" "extfat" "ext4"
                            none of them mounted.. unless i change the fstab uuid
                            and set the usbmount to Enabled in the menu
                            then sometimes it mounted

                            so the results for the tests are

                              My example was without the UUID, just using the partition inode directly. If you re-format the drive, it's label may change, so the UUID may not match.

                              EDIT: add the entry to /etc/fstab, then try running

                              mount -a -t exfat
                              

                              and if the drive is mounted (mount -t exfat).

                                ok so not sure what to change in my fstab

                                proc            /proc           proc    defaults          0       0
                                PARTUUID=e22bcd10-01  /boot           vfat    defaults          0       2
                                PARTUUID=e22bcd10-02  /               ext4    defaults,noatime  0       1
                                # a swapfile is not a swap partition, no line here
                                #   use  dphys-swapfile swap[on|off]  for that
                                UUID=3FDD-79EC  /home/pi/RetroPie       vfat    nofail,user,uid=pi,gid=pi 0     2
                                

                                is my current Fat32 for the 2TB drive
                                everytime i format it changes the UUID so then i re change it in the fstab

                                and what i was meaning is /home/pi/RetroPie vfat
                                i changed the vfat to "ext4" "exfat" "exfat4"
                                when i had it formated as exFat or whatever the proper wording is for it

                                to see if it would mount.. it would sometimes mount as /media/usb0

                                so wehre in the fstab do i add /etc/fstab

                                and i guess reformat the drive to exfat right?

                                and i did try where vfat is when i had "ntfs" i tried changing it to "ntfs-3g" but that didnt help either as i read that in a different retropie article someone said worked but didnt work for me
                                when i had it as ntfs

                                  Sorry, but it's getting difficult to follow your replies without any phrasing or punctuation. Can you make an effort and organize your replies better ? I understand English may not be your native language, but try to make an effort and put some structure into it.

                                  • First, make sure you format your drive as exfat, use the mkfs.exfat command I've mentioned. Use cfdisk /dev/sda or fdisk -l /dev/sda to confirm the drive is properly formatted.

                                  • 2nd, modify /etc/fstab and replace the last line with the entry I mentioned a couple of replies ago:

                                  /dev/sda1  /home/pi/RetroPie       exfat   nofail,user,uid=pi,gid=pi	0	2
                                  
                                  • 3rd, try the mount commands from my previous reply to make sure that you've correctly modified /etc/fstab and mounting works. If none of the commands fail, then you can disable the usbmount service and reboot to see if the external disc is mounted correctly (to /home/pi/RetroPie).

                                    sorry try my best as i have dislexia and its sounds clear to me

                                    what i was say
                                    in fstab file
                                    vfat line i changed it to "ext4" "exfat" "exfat4" for Exfat
                                    non of these settings "mounted" the drive tp /home/pi/RetroPie
                                    only to /media/usb0 and you had to have the Auto USBmount service Enabled in the Menu.. Disabled wouldnt mount

                                    when it was ntfs i treid "ntfs" and "ntfs-3g"

                                    and i was sayin since its in Fat32 i guess i have to reformat it

                                    and i said i had to change the UUID in the Fstab every single time when i formated the drive

                                    pi@retropie:/etc $ sudo mkfs.exfat /dev/sda1

                                      The errors below

                                      cfdisk: cannot open /dev/sda1: Permission denied
                                      pi@retropie:~ $ fdisk -l /dev/sda
                                      fdisk: cannot open /dev/sda: Permission denied
                                      pi@retropie:~ $ fdisk -l /dev/sda1
                                      fdisk: cannot open /dev/sda1: Permission denied

                                      are because I forgot to prefix them with sudo (they need root access). Try

                                      sudo fdisk -l /dev/sda
                                      

                                      and check if the /dev/sda1 partition is reported as NTFS/exFAT.

                                      The same with the mount commands.

                                      sudo mount -a -t exfat
                                      FUSE exfat 1.3.0
                                      WARN: volume was not unmounted cleanly.
                                      fuse: mountpoint is not empty
                                      fuse: if you are sure this is safe, use the 'nonempty' mount option

                                      The first message is because the fuse variant is installed, though it shouldn't interfere. You can uninstall it first by running

                                      sudo apt remove exfat-fuse
                                      

                                      and the mounting will use the native Linux exfat support. Re-try then to run

                                      > sudo mount -a -t exfat -o nonempty
                                      

                                      and then check by running mount that /home/pi/RetroPie is mounted using exfat.

                                          OK, so the disc is not formated as exfat and mounted via the native kernel support, without fuse. This should take out the extra CPU consumed by using fuse and ntfs.

                                          If you're copying just a large file over the network, do you get the same - low - speed ? Is this over a wired or wireless conenction ?

                                          I know the NesPi case - the older versions ? - had an issue with the SATA controller used in the case (see this topic), it might be worth checking if the case you're using falls has the SATA controller that is problematic.

                                          Just

                                            i thought the disk got formated as exfat

                                            /dev/sda1      exfat     1.9T  2.2M  1.9T   1% /home/pi/RetroPie
                                            

                                            so what do you mean exactly by "OK, so the disc is not formated as exfat and mounted via the native kernel support, without fuse. This should take out the extra CPU consumed by using fuse and ntfs."

                                            explain it for someone that doesnt know the fuse and the native kernel support or the extra cpu consummed etc
