any simple software to test read/write speed on ssd?

Post by freshtamatic » Sat Sep 22, 2018 2:39 pm

I installed a new SSD on my laptop, and I am sure it's running slower than when it had an old HDD. I just need a non complicated software to read/write and output speeds?
I'm on LM Cinnamon now, but the laptop is on LM MATE

There are some fancy graphical tools, but

Code: Select all

time cp big-file to-file
is pretty simple. But then there's 'sync' (dump IO from memory to disk), I'd do
$ sync
$ time sh timer.sh

timer.sh

Code: Select all

cp somebigfile tosomefile
sync
(There's probably some way to do that on one line, but...there ya go!)

$ time sh timer.sh
real 0m0.715s
user 0m0.000s
sys 0m0.216s

Oh boy. Too complicated for me, any GUI ones?
Thanks.

sudo hdparm -t --direct /dev/sda for the correct /dev/sda is the basic sequential-read speed test, to be used to see if things are right or wrong at the lower levels. Just open the terminal and copy/paste that in.

If it's a second-hand SSD, note that a firmware-level format will usually restore the drive to full working state if indeed you find that something's definitely wrong. I've had that happen with (almost) new Intel SSDs. Said formatting can be done through hdparm as well, but I tend to advise to stick the SSD in a Windows system and do so using the vendor-tool, especially since you can then first check for updated firmware as well.

Did you even look? Mint menu > Disks is hard to miss. ;) Benchmark Disk option in the hamburger menu at the top.

'gnome-disks' was the GUI one I thought of...

Edit: have to unmount the partition/disk, which makes it far more complicated than it should be.

Sorry hadnt looked at the menu, I ended up using it.
here are the results:
240 GB Disk — SanDisk SSD PLUS 240 GB [UF3000RL] (/dev/sda)
average sample: 100,0 MiB (104857600 bytes)
average read: 144,1 MB/s (100 samples)
average write rate: -
average access time : 0,85 msec (1000 samples)

Why no write rates? Isn't it slow?
