The Lenovo Legion 5i 15 is a formidable mid-range gaming option with plenty of features gamers will love. It also happens to have dual M.2 solid-state drive (SSD) slots, as well as space for a 2.5-inch SATA SSD. However, not all spots can be occupied at the same time. If you're interested in upgrading your laptop's storage after purchase, we have everything you need to know right here. Though we're performing the operation on the Intel-based Legion 5i, it should be the same process for the AMD-powered Legion 5.

Hardware and software to get the job done

How to upgrade the main SSD in Lenovo's Legion 5i 15

Note: Before beginning any upgrades on a PC, it's a good idea to back up your data in the unlikely event something should go wrong. You'll also want to ensure you're not working in a static-filled environment since it can cause damage to a PC's internal hardware. Consider investing in an anti-static wristband to avoid unnecessary damage.

Lenovo's Legion 5i 15 is available in several different configurations to best fit your budget and needs. Baseline models usually ship with only an SSD, while more expensive options have both an M.2 PCIe SSD and a 2.5-inch SATA hard-disk drive (HDD). No matter what, the boot drive for Windows 10 will be the M.2 SSD for faster speeds.

The internals are laid out so that there's always a spot for an M.2 SSD, whereas the secondary storage option must be either another M.2 PCIe SSD or a 2.5-inch solution (SSD or HDD). There's no room for all three. Although a 2.5-inch SATA HDD or SSD is going to be cheaper for large storage sizes, we recommend upgrading with dual M.2 PCIe SSDs for better performance. Something like the Samsung 970 EVO Plus is an excellent option.

If you're upgrading the M.2 SSD boot drive that shipped with the Legion 5i, you might want to invest in an SSD enclosure. This will allow you to connect the new SSD to the laptop and clone any data on the boot drive over to the new drive. For cloning we've had success with Macrium Reflect; we've even written a guide to get you through the cloning process.

If you'd rather replace the M.2 boot drive entirely without cloning any data, you can start fresh with a clean Windows 10 install once the upgrade is complete. There are some steps to take care of before you begin the SSD upgrade, so be sure to head over to our guide to a clean install of Windows 10 to see what's required.

Once you've completed any cloning or have set yourself up for a clean installation of Windows 10, clear out a well-lit workspace and power down your Legion 5i 15 before proceeding with the steps below.

  1. Unscrew the 11 fasteners on the bottom of the laptop using a Phillips screwdriver. They back out entirely, so be sure you have a safe space to collect them. The four short screws go along the front of the chassis.

You can now go ahead with a fresh install of Windows 10 or, if you cloned the drive beforehand, you can boot up the PC to see if the upgrade went according to plan.

How to add a secondary SATA SSD to the Legion 5i 15

If you're content with the boot drive in the Legion 5i 15 staying as it is, you can still add a second M.2 SSD or 2.5-inch SATA SSD for bonus storage. In a gaming laptop that deals with colossal game file sizes, this is especially important. The way the laptop is designed, you can either add an M.2 SSD or a 2.5-inch SATA SSD, so you need to choose before beginning the upgrade process. In this section, we will deal with adding a 2.5-inch SATA SSD. We recommend the Samsung 860 EVO as an excellent pick for a 2.5-inch SATA SSD.

If your laptop already has a secondary SSD and you want to keep the data, you can always go through with the same cloning process, as we explained in the preceding section. Once you're ready to upgrade, clear out a well-lit area and power down your Legion 5i 15.
