A lot of people copy over their old alignment when migrating to a SSD. Thought this would be handy for people to check:


Type cmd in the Search field and press Enter.
At the command line prompt type:
wmic partition get BlockSize, Index, Name, StartingOffset

You will get the output looking like this:

In the screen shot, disk 0 has an incorrect alignment and disks 3 and 4 have the correct alignment.

There are multiple tools to fix it. Partitionwizard.com has a free one, or you can google how to manually fix. Also make a backup before trying to fix it.

Won't affect most people i'm sure. I've seen it on occasion though and use MiniTool Partition Wizard to sort it out. Great (free) program... pretty much Windows' answer to GParted.

From what i remember about the topic, if it's not aligned then your SSD will write to more blocks than it needs to. Think of it like walking on cracks in the pavement, so you end up walking on more pavement tiles in total. But for an SSD, this slows it down (writing to more blocks than it should) and reduces life (blocks being written to more often = hit the write-lifecycle sooner).

If i'm off, then someone correct me... this is just how i remember it.

Number should divide by your block allocation size, to a whole number. In modern Windows versions this should be 4096 (not sure about XP and such).

The "1048576" next to each #0 partition. 1048576 / 4096 = 256. No decimal = good to go.
