There are some old articles like http://lifehacker.com/5837769/make-sure-your-partitions-are-correctly-aligned-for-optimal-solid-state-drive-performance that come up when you search for SSD.
Some like this one How do I check whether partitions on my SSD are properly aligned? have dead links (http://blog.aloisiojr.com/?p=28).
So in 2016 with ubuntu 16 (using from live USB), So I still need to care about aligning my SSD disk correctly (dual boot windows).
I ask cause sometimes the shutdown is slow. Not sure if this was due to closing the wbe server, IDE etc (dev system), Or cause of align issues.
When I run the parted tool it says its fine with the commands:
sudo parted

I understand that the tool is saying it is fine, but how is that as the 314573/4096 is not a whole number?
About my SDD: Model KINGSTON SV300S37A480G (603ABBF0)
Size 480 GB (4,80,10,39,81,056 bytes) GUID Partition Table Disk is OK (33° C / 91° F)
How do I find out what correct align numbers for this? Or can I trust parted and rest easy?
partedsays it's aligned properly, it is aligned properly.sudo parted /dev/sda unit s printorsudo gdisk -l /dev/sda
