Verbatin V3 MAX 32GB speed test

Looking for a fast USB drive to use on my Chromebook, which only has USB2, I came across what appears to be bargain "fast" USB3 drive from Verbatim. Claimed transfer is 175MB/s on USB3, of course you will not get this on USB2 but I was hoping it would comfortably max out the USB2 limits. 

Here are the results:


On my HP laptop:

[~] # hdparm -t /dev/sdb

 Timing buffered disk reads:  96 MB in  3.03 seconds =  31.69 MB/sec

[/media/VERBATIM] $ dd if=/dev/zero of=test bs=10240 count=102400
102400+0 records in
102400+0 records out
1048576000 bytes (1.0 GB) copied, 42.0829 s, 24.9 MB/s

Which is what I was hoping for, from wikipedia the maximum USB2 throughput is  35 MB/s. 




Encrypt your USB memory stick

What to feel like Edward Snowden and walk around with an encrypted memory stick in your pocket?
Use cryptsetup to create LUKS encryption on your removable media. 


A lecture on backups and how to encrypt removable media

Golden rules of backups
- at least 3 copies.
- stored in atleast 2 different locations. 
- any removable media is encrypted. 
- if the backups have not been tested they do no exist. 
- RAID does not count as a copy. 

If you are using USB drives to backup your data, you have no excuse to not encrypt them. The handy procedure is exactly the same for USB sticks and is supported by all the main Linux distributions.
