Entware Entware: which USB stick performs well?

[sfx2000]

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

heads up - error 404 on the links

Thanks and known issue..

I have two VPS each on one side of the Atlantic. The new one went down for few hours already. So I've pointed the domain back to the old VPS that doesn't have the content after the migration. Hence, people will see an old snapshot...(better than seeing Cloudflare errors). The links in OP are not available in the old VPS.

A couple of weeks ago I decided to change my usb stick to usb3 for entware and ab solution. They were previously on an old usb2 stick and I actually noticed lagging. Bought a brand new Toshiba usb3 stick, formatted it and installed the AB and... it was lagging worse. Couldn’t figure it out. Bit the bullet and bought a SanDisk. Did a benchmark on unbuntu to compare the two sticks and it showed that the toshiba was allegedly faster. Went ahead and installed ab onto the SanDisk and haven’t had any issues with lagging since. And also, the toshiba works fine on my other systems. Never could figure out what was the issue.

Obviously am gonna install this nifty tool and see what’s what. Thank you for sharing this!

Thanks sfx2000 for the heads up
I thought it was just me

I am thinking about installing AB solution, and other scripts in the future and trying to decide to what USB brand to order....Any recommendations? So far San Disk, Samsung have come up. Are there any other brands you would recommend? as 2.0 vs 3.0. Would 3.0 be a better choice?

I am using a Sandisk usb3 32GB flash, and I have not had any problems to report. I am using that stick for technical reasons, it was on sale.

Here is a copy of original post I made on Discord channel. It still works.

Installation - ARMv7 routers

wget -qO- https://gitlab.com/kvic/Entware-Goodies/raw/master/iozone-v3.482-armv7.tar.gz | tar xf - -C /jffs/bin

You could replace /jffs/bin with another path.

Installation - aarch64 routers

wget -qO- https://gitlab.com/kvic/Entware-Goodies/raw/master/iozone-v3.482-aarch64.tar.gz | tar xf - -C /jffs/bin

You could replace /jffs/bin with another path.

Uninstall

rm /jffs/bin/iozone

To benchmark target disk I/O - take Entware disk as example

cd /opt
/jffs/bin/iozone  -e -I -a -s 20M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2

If you post test results, @sfx2000 and I would be able to offer you an assessment for free. lol

(my new VPS has been down for 24 hrs... I'm trying to get back my data.)

From the test data I've seen so far, if people want to spend little, grab a SanDisk Cruzer Blade USB 2.0 if you could find it on sale. @Protik is using this one. Move up a little, can consider SanDisk Ultra Flair USB 3.0 - it's my Entware stick.

So @Marin, your pick... Recommendation will change when I collect more samples.

 

[john9527]

Do you think the format of the target will change the results....ext2 vs ext4?

Filesystems should have effect. See, for example, sequential write (open in a new tab for full resolution):

However, I doubt it has observable impact on random read/write on USB sticks/SD cards. Random read/write is important criteria here but the bottleneck is apparently vendors' memory chips put in different brandings..

I was using ext4 in my tests. What did others use?

This is using a RT-AC86U and a Lexar 64G USB3 stick formatted ext4 plugged into the USB2 slot on the router.

 

[kvic]

@punkinduster I will add your stick to iozone-db.txt. Is it a Lexar JumpDrive S57 64GB USB 3.0 flash drive?

@XIII I use ext4 too.

ext4 on the SD card I provided data for

It is the Lexar JumpDrive Triton 64GB USB 3.0 that I bought about 6 yrs ago.

Got it and found it on Amazon. One of the fastest back then. Read/Write up to 150/150MB/s. Must come with a premium price..

Old hero is aging fast! I shall say its random 4KiB write performance doesn't reflect its premium but we all know it's from 6 years ago.

OMG!

This beast is in its own class. No one is near.

@Beherit I'll add it to iozone-db.txt

Reading further on this beast. It's basically a SSD with a USB 3 connector. It shall be running UASP. Does Merlin firmware support it? @RMerlin

If the firmware enable UASP, I believe this beast and any USB 3.0 attached storage shall run much faster.
