T420: mSATA SSD performance issue [SOLVED]

[Farro]

hi guys ,
i am wondering is someone can help me pin the issue: I recently added a 128GB msata ssd to my T420. When i check the disk for io i get this:

dd if=/dev/zero of=/tmp/output conv=fdatasync bs=384k count=1k; rm -f /tmp/output
1024+0 records in
1024+0 records out
402653184 bytes (403 MB, 384 MiB) copied, 1.86245 s, 216 MB/s

and

sudo hdparm -Tt /dev/sda
[sudo] password for XXXXX:

/dev/sda:
Timing cached reads: 9834 MB in 2.00 seconds = 4918.77 MB/sec
Timing buffered disk reads: 818 MB in 3.00 seconds = 272.28 MB/sec

but this is the issue .. when i try to close thunderbird ( email client ) it takes forever to close ..
i had another 128GB ssd disk ..in which when i close thunderbird ..its instantaneous ..

also the reboot takes forever

ps: i am not using any swap

i am thinking its got something to do with msata ... can someone help me out ?

You should fix your thread title from T400 to T420.

I've noticed the same delay when closing thunderbird.
My solution:
1. a keyboard shortcut to 'pkill thunderbird'
2. echo 'tmpfs /home/USER/.cache tmpfs noatime,size=512M 0 0' >> /etc/fstab
3. add entry to thunderbird 'browser.cache.disk.parent_directory' value = /home/USER/.cache
