how do you get faster write speeds to SSD only getting 24mb/s

@mitu
ill re ty again and the test i did was on the bottom of the forum pagei ran
pi@retropie:~ $ sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches" pi@retropie:~ $ dd if=./largefile of=/dev/null bs=4kand ran
dd if=/dev/zero of=./largefile bs=1M count=1024so i installed it and ran

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

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
Did you try to use the
fstabline that you previously posted ?/dev/sda1 /home/pi/RetroPie exfat nofail,user,uid=pi,gid=pi 0 2When 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 mountedso the results for the tests are

none of them mounted.. unless i change the fstab uuid
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 runningmount -a -t exfatand 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 2is my current Fat32 for the 2TB drive
everytime i format it changes the UUID so then i re change it in the fstaband 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 itto 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 themkfs.exfatcommand I've mentioned. Usecfdisk /dev/sdaorfdisk -l /dev/sdato confirm the drive is properly formatted. -
2nd, modify
/etc/fstaband 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/fstaband mounting works. If none of the commands fail, then you can disable theusbmountservice and reboot to see if the external disc is mounted correctly (to/home/pi/RetroPie).

@mitu
sorry try my best as i have dislexia and its sounds clear to mewhat 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 mountwhen 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

OK, so the disc is not formated as
exfatand mounted via the native kernel support, withoutfuse. This should take out the extra CPU consumed by usingfuseandntfs.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.

@mitu
i thought the disk got formated as exfat/dev/sda1 exfat 1.9T 2.2M 1.9T 1% /home/pi/RetroPieso 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
network is cabled 1gb connection..
its copying any file.. that i getting only 2-10mbs the dd command shows 18mb/s is that saying its only read writting? large or small just doesnt matter ):im using the nespi 4 from my how to guide i made
https://retropie.org.uk/forum/topic/28848/guide-how-to-setup-nespi-4?_=1646095106362so i dont know if it falls under that i thought i solved the slow problem speeds with my article about mounting the sata controller as i think i read that article and thats how i made my article from it

so i dont know if it falls under that i thought i solved the slow problem speeds with my article about mounting the sata controller as i think i read that article and thats how i made my article from it
Did you add the quirks configuration to
/boot/cmdline.txt? Can you try without it ? -
@mitu
yes and noi actually still running the same nintendo nesp case you see in the article i made.. all i did for myself was upgrade from 250gb to a 2tb and i use the 250gb in a new system for a friend.. and speeds were fine for it..
so i didnt need to change the cmdline as i made thes changes back in 2020 .. but ill try removing the part in the cmdline to see if it works for a 2tb i had to add it for the 250 and 500gb

i gonna try to copy over some couple gig files
so copying just random files i get 3-5mbs
random files of 159gb i jsut sliding over is going to take 8hoursso removing the cmdline info i added didnt help ):
but its a limit with this usb hot swap and 2TB maybe its only good for 1TB and less?
i dont have a smaller SSD anymore to test it ):
-
so selecting 4 files all together 8 gb
it started at 90mbs then dropped down to 2mb then up and down but finishedthats with the removal of the extra for the the cmdline.txt
but the other file copying of smaller more files is at 2.38mb/s saying going to take 15 hours now to copy 156gb
i selected 73 files that equaled 159gb to test to copy.... it peaks at 90mbs/ averages like 60mb and says takes 35min to transfer 159gb not the 15 hours for the smaller files ...
should i re add the info to the cmdline.txt and see what happens ..
is it an issue then for small files? and if so anyway to improve speeds for small files
-
had to re add
usb-storage.quirks=152d:0562:u
to the cmdline.txt when you did a reboot was ok.
but when you turned it off.. and turned back on... the usb drive wouldnt not mount
so i re added
usb-storage.quirks=152d:0562:u
then rebooted then the drive mounted..
it can copy big files like 70 meg/s but small files etc slow and takes forever i dont get it.. but if i copy to my windows to unraid server is faster for small files is it possibly not fast cpu?
-
Multiple small files will always be slower to copy than larger files. The CPU should be plenty fast, but I/O (disc/network/internal PCI bus) is not the same as on PC, plus the quirks added which disable UAS in favor of the slower USB mas-storage driver have also an impact.
-
oh so the quirks whatever that is slows the usb port down? or the transfering...
so i wonder if newer nespi4 have it fixed the usb mass storage
does it impact using retropie then loading roms or what not.. or just mainly over network..
and do you guys run the retropie OS on the SD card or do you run it on the SSD
-
@comet424 said in how do you get faster write speeds to SSD only getting 24mb/s:
oh so the quirks whatever that is slows the usb port down? or the transfering...
Yes, using UAS would allow for faster disc operations, this is noted in the troubleshooting topic on the RPI forums:
UAS is an upgraded transport protocol compared to USB mass-storage - commands and data are separated into different queues and multiple outstanding commands can be in flight at the same time, as opposed to USB mass-storage's lock-step relationship between commands and data. This allows better saturation of the 4GBps USB3.0 transport as there can be a continuous stream of data to and from a device
so i wonder if newer nespi4 have it fixed the usb mass storage
I don't know and their web site doesn't have an easy to find changelog, but you can send them an email and ask about it.
does it impact using retropie then loading roms or what not.. or just mainly over network..
I don't think so, even with the USB storage quirks the disc should be faster than a regular SDcard.
-
oh ok.. learn something new everyday
i guess once the roms are on the disk its fast enoughand do you recommend putting retropie OS on the SSD to as well? as 1 i do not know how to do that.. havent googled.. as i know the sd cards only last so long
or is it just ok to leave the os on the SD card?
