Alignment comparison of a cloned SSD – The Benchmark

Standard

In this test we will show you the problems which occur, if the HDD alignment is not correct working. Here you can see, how the performance can be different. 

If you install Windows on a new SSD, the partitions will be automatically setup correctly. But if you want to clone your old system on a new SSD, this alignment will often not work automatically, and have to be setup by yourself. This depends on the tool you are using to clone your HDD and on the SSD itself.
Why the alignment is very important, how you can check it, and how you can change it manually, can be find in this our article: SSD Alignment – How you can change it – With videoIn this our test we will show you the different between the performance of a aligned SSD and an unaligned one. In the test we got a Vertex 2 and a Vertex 3 SSD for the comparison.

Vertex 2 – wrong alignment

Vertex 2 – good alignment

Vertex 3 – wrong

Vertex 3 – good

The difference between the aligned and unaligned SSDs are clear to see in the pictures. The writing rate is really bad without an alignment. In addition, the lifetime of the SSD can get very short through a wrong alignment.
