Entware Entware: which USB stick performs well?

[XIII]

This weekend @kvic posted a new tool to measure the performance of the USB stick in your router: https://kazoo.ga/benchmark-usb-flash-drives-on-routers/

Turns out my SanDisk Ultra Fit 32GB USB 3.0 Flash Drive is not performing too well: https://kazoo.ga/content/images/iozone-db.txt

What USB drive do you recommend for Entware?

Or maybe: which one do you use now? And can you add your results to the DB?

 

[kvic]

"SanDisk Cruzer Fit 16GB USB 2.0 Flash Drive" was my old Entware disk. Back then CPU shot up to 100% when doing large file copy into the disk. LoL

"SanDisk Ultra Flair 64GB USB 3.0 Flash Drive" is my current Entware disk though it's already a few years old..

Both test results are available in the iozone-db.txt.

I hope to maintain a db for flash drive, and a separate one for Micro SD (and perhaps SD). Have fun and send in your test results!

The instructions on this site: https://kazoo.ga/benchmark-usb-flash-drives-on-routers/ do not work on my AC3100. I must say that the only version of Entware I have is the version that comes with pixelserv-tls install.

The results in the ssh session to install:

wget -qO- https://gitlab.com/kvic/
Entware-Goodies/raw/master/iozone-v3.482-armv7.tar.gz | tar xf - -C /jffs/bin
tar: can't change directory to '/jffs/bin': No such file or directory

/jffs/bin is not a default folder. If you create it first it might work...

mkdir /jffs/bin

/jffs/bin is not a default folder. If you create it first it might work...

mkdir /jffs/bin

Tried that in winscp nope it runs the install and /jffs/bin is populated with one file. If I run the command to test, it complains that the directory doesn't exist.

mkdir /jffs/bin

I'm wondering if I have enough of Entware to do this. I only have the Entware install from AMTM.

did you run with full path in the command? /jffs/bin/iozone ....

Yes sir @john9527 it is running right now!

I have two usb sticks on my router. Is this script testing both at once or....?

It tests whichever stick is associated with the active directory....

cd /xxxx
to a directory on the stick you want to test

Thanks again @john9527 works as you say.

@skeal

upload your make of sticks and test results here

Sure will!

Here's a sample - note this is an SD Card (actually MicroSD card) so the interface speed is limited by the host (RPi3B+)

git clone https://github.com/pantheon-systems/iozone.git

SanDisk Extreme 32GB MicroSD card

On Raspberry Pi3-B+ on a whim...

Entware or other - I really do like the SanDisk stuff - Samsung is a close second if SanDisk isn't available.

Cool and good to know about this card

is yours pre-A1 or comes with A1 moniker?
I have a SanDisk Ultra 16GB MicroSD card /w A1 moniker on order.
If I had tripled my pay, I could have ordered your version.

I added sfx2000's card to iozone-db.txt on kazoo.ga blog.

Since my last presence on this thread, @Protik also submitted a stick used for Entware partition. So far the best deal in the list I've to say! @XIII paid triple the price with less performance for application use...lol

It's an older card I did on a bulk buy back in 2016... it's UHS-1, no A1 moniker....

Nice because it does support TRIM

Amazing they could stuff TRIM support in such a small package!

How to find out if a stick/card supports TRIM?

How to find out if a stick/card supports TRIM?

Check the lsblk --discard return - DISC-GRAN (discard granularity) and DISC-MAX (discard max bytes) - non-zero values indicate trim support

sfx@raspy3:~ $ lsblk --discard
NAME        DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
mmcblk0            0        4M     584M         0
