Kingston DataTraveler extremely slow

Post by jeenuv »

I find that ext formatting a Kingston DataTraveler 64GB USB3.0 pen drive is taking over an hour! Even after formatting, data transfer is painfully slow.

This happens only with Kingston devices. I've so far tried 2 brand new devices of the same make, and both have the same problem. I tried formatting a Sandisk USB 3.0, and that was completed in a jiffy.

Here's lsusb -v on the Kingston.

Taking cue from elsewhere, I wrote 0 to /sys/module/usbcore/parameters/usbfs_memory_mb; but that didn't help.

Here's my uname -a:

Code: Select all

Linux jeenu-laptop 4.15.0-58-generic #64-Ubuntu SMP Tue Aug 6 11:12:41 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Any help is appreciated.

Yes, they are slow. The data travelers I have are about 5MBs write speed. I only use them now for on a key ring, which they fit well onto, otherwise prefer the Samsung.

I'll add this. A few years back I used them almost exclusively, but NOT for a full install, ONLY as a LIVE USB flashdrive with "persistence" on it. That at least used the compressed ISO file as the operating system, since the CPU could decompress the data from the ISO faster than reading it from an fully installed system on it. Doing it that way on such slow USB flashdrive did help it run faster, and really didn't seem much different than using a fully installed/expanded system. If you want to try that method instead, I'd advise using mkusb program to install it to the flashdrive. It really makes a speed difference at least for running the system using that method.

Also, don't use any encryption if doing full install to the flashdrive, that only increases the slowness problem.

osdisc.com used Kingston earlier, but then they moved to these, and their write speed is about 5 times faster, and the read speed even faster, yet the cost is comparable.

All things go better with Mint. Mint julep, mint jelly, mint gum, candy mints, pillow mints, peppermint, chocolate mints, spearmint,....

Ah, thank you. I was worried that it's my laptop/driver/USB port's fault. I'll remember to avoid them in the future.
