Yes. Every storage platform no matter what vendor makes it needs to be correctly aligned. If the disks aren’t correctly aligned then you are doing twice as much work for every read and write operation than you need to be doing.
Fortunately new volumes created on a Windows 2008 or higher server (or Vista or higher client OS) will be correctly aligned. They will be aligned at the 1024kb mark instead of the 64kb mark, but as long as the place they are aligned to is evenly divisible by 64k then it’ll be fine.
