What Is the Best Disk Partition for SSD and How to Get It

  • Contents:

    Compared with common hard disk, a solid state drive (SSD) is much better largely because of its amazing speed. A SSD-equipped PC or laptop may boot in seconds while a HDD requires dozens of seconds or even more than 1 minute. However, if we want to experience amazing speed of SSD, we should create correct partitions. Well then, what is the best disk partition for SSD?

    Simply speaking, partitions on SSD should be aligned correctly. If they are misaligned, both read and write speed will be affected. Under Windows OS released before Vista, users need to align partitions manually. But under Windows Vista and later Windows OS, all newly created partitions will be aligned automatically.

    However, if a partition on SSD has been operated like resized or moved, it may become unaligned. Moreover, if partitions on SSD are migrated or copied from other disks, they are always unaligned. Well then, how to check whether disk partitions on SSD are best or not? Please do the check in diskpart. Here, we take Windows 7 for example.
    • Click Start menu, type diskpart in Search programs and files box, right click diskpart program and run it as administrator.
    • Type the following 2 commands successively (every type ends with clicking Enter key): select disk N (N is the number of the SSD) – list partitions.
    After that, we can see the following information:
