USB thumb-drive speed

Postby DaddyX3 » Thu May 08, 2008 7:15 pm

Ok, same protocall as the hard-drive speed tests. To check what /dev your usb thumb-drive is first do a
sudo fdisk -l
Then plug your usb drive in and repeat. You should see another /dev in the list now. Once you know what /dev/XX it is just enter the following in a terminal:
Code: Select all
sudo hdparm -t -T /dev/xxx

replacing "/dev/xxx" with you devise name listed in fdisk output.

I'll start .....
My junker .... Lexar 2GB WalMart Special a.k.a. P.O.S.
Code: Select all
/dev/sde:
 Timing cached reads:   1532 MB in  2.00 seconds = 766.14 MB/sec
 Timing buffered disk reads:   30 MB in  3.14 seconds =   9.57 MB/sec


My OCZ Rally 2 stick .... a.k.a. "not" a Walmart Special ...
Code: Select all
/dev/sde:
 Timing cached reads:   1420 MB in  2.00 seconds = 710.10 MB/sec
 Timing buffered disk reads:   54 MB in  3.03 seconds =  17.82 MB/sec

I've seen 20MB/s but not any more than that. I'm curious to see if there is any difference with a faster computer?

I think I'll try this with my cameras SD card. Do you think the adapter will have an effect on speed? I have an adapter that came with the card as well as a multi-card reader. Actualy, the multi-card reader shows up under computer as different drives, even with nothing in the slots. I thought that was a bit odd.

give it a run jfg! I have a card reader on my HTPC that does the same thing. I'm running on that though. I'm not sure about Hardy with a card reader.

WOW! This is all I can say. I can't believe the improvement in speeds, from my old computer (3800+ X2/ ASUS AN8 32 SLI Deluxe/2-GB RAM) to my new computer!!!! Check these #'s out for a thumb-drvie!!! New system specs in my sig.

Mind you, same exact thumb-drives:
OCZ Rally2 8GB:
Code: Select all
zzmadi@zzmadi-desktop:~$ sudo hdparm -t -T /dev/sdd

/dev/sdd:
 Timing cached reads:   4308 MB in  2.00 seconds = 2154.52 MB/sec
 Timing buffered disk reads:  100 MB in  3.03 seconds =  33.05 MB/sec


Had to run it twice ... didn't believe it:
Code: Select all
zzmadi@zzmadi-desktop:~$ sudo hdparm -t -T /dev/sdd

/dev/sdd:
 Timing cached reads:   4314 MB in  2.00 seconds = 2157.85 MB/sec
 Timing buffered disk reads:  100 MB in  3.03 seconds =  33.05 MB/sec


Then put in my Walmart special Lexar 2GB thumb-drive:
Code: Select all
zzmadi@zzmadi-desktop:~$ sudo hdparm -t -T /dev/sdd

/dev/sdd:
 Timing cached reads:   3966 MB in  2.00 seconds = 1983.52 MB/sec
 Timing buffered disk reads:   36 MB in  3.11 seconds =  11.59 MB/sec

-NO surprise there! A piece of junk thumb-drive is a piece of junk thumb-drive. No amount of system upgrades will fix that. Although There is a little improvement :)

This is for a 4gb microSD card from my smartphone using a USB adaptor I might add its formatted in NTFS so I might be losing some for that. I'll test my USB stick in a few minutes and post results as well.

I thought I would join in the fun, got a new 8GB "Sandisk Cruzer" yesterday, first I will start with the Lexar Walmart special:
Code: Select all
theemahn@SledgeHammer:~$ sudo hdparm -t -T /dev/sde1

/dev/sde1:
 Timing cached reads:   2634 MB in  2.00 seconds = 1316.64 MB/sec
 Timing buffered disk reads:   48 MB in  3.09 seconds =  15.56 MB/sec
theemahn@SledgeHammer:~$


Sandisk Cruzer:
Code: Select all
theemahn@SledgeHammer:~$ sudo hdparm -t -T /dev/sde1

/dev/sde1:
 Timing cached reads:   2568 MB in  2.00 seconds = 1283.63 MB/sec
 Timing buffered disk reads:   72 MB in  3.06 seconds =  23.50 MB/sec
theemahn@SledgeHammer:~$



I would also like to help you fellas get the "most" out of your USB stick, most people perceive that their motherboard's USB slots are all 2.0, this is not always the case. I am going to take the time to show you how tell tell which ports are 2.0:
Code: Select all
theemahn@SledgeHammer:~$ lsusb
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 003: ID 09da:001a A4 Tech Co., Ltd Wireless Mouse & RXM-15 Receiver
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 005: ID 0781:5406 SanDisk Corp. Cruzer Micro 1/4GB Flash Drive
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Wow, look at that only 2 of the 6 ports shown are 2.0, figuring out which are 2.0 is done by watching how many ports are 2.0 and when you see your flash drive listed and 1 less 2.0 port then you have it in a 2.0 port, I hope this has helped someone.

lsusb is a great little tool to view devices in verbose a -v switch can be added:

Re: USB thumb-drive speed

I paid for a dual sided USB flash drive 4x Winner of Customer Choice Award - on newegg at least for speed 200X... Gents do not be deceived, once the USB port has been saturated you are done. $10 lesson well learned.

The New drive:
Code: Select all
theemahn@SledgeHammer:~$ sudo hdparm -t -T /dev/sdd1

/dev/sdd1:
 Timing cached reads:   3072 MB in  2.00 seconds = 1535.59 MB/sec
 Timing buffered disk reads:   68 MB in  3.02 seconds =  22.52 MB/sec
theemahn@SledgeHammer:~$


You can see the 8 gB stick I have above is faster and this one is only 4 GB, supposedly 200 times faster, once your usb port is maxed out you are done, aka bottleneck.
