The Moto G5 Plus accepts a microSD card up to 128GB. Motorola recommends a high-speed UHS-I card for best performance when using the card as internal storage, but capacity support remains capped at 128GB: do not buy a 256GB, 512GB, or 1TB card for this phone on the assumption that it will be supported. Every pick below is a microSDHC or microSDXC UHS-I card at 64GB or 128GB. Choose portable storage if the card must move between devices; formatting as internal storage ties the card to this phone and does not guarantee that every app can be moved.

Samsung EVO Select 128GB microSDXC
A 128GB UHS-I EVO Select, which reaches but does not exceed the Moto G5 Plus’s stated capacity limit. It is rated U1, V10, A1, and Class 10; use it for removable media or format it in the phone only if it will remain there.

Samsung EVO Plus 128GB microSDXC

Samsung PRO Plus 128GB microSDXC
A 128GB UHS-I PRO Plus that meets the G5 Plus capacity ceiling. Samsung rates the PRO Plus U3, V30, A2, and Class 10, but the phone’s own interface and workload determine real-world benefit; its higher card rating does not change the handset’s 128GB limit.

- maximum supported capacity
- extra speed may not benefit every phone task

SanDisk Extreme 64GB microSDXC UHS-I
A 64GB SanDisk Extreme microSDXC UHS-I option for a user who wants a higher-rated card while staying below the phone’s capacity cap. It remains removable phone storage; Android behavior for individual apps is controlled by the handset and app, not the card label.

- within supported capacity
- premium rating may be unnecessary for media
- not a 128GB option
SanDisk Extreme 128GB microSDXC UHS-I
A 128GB SanDisk Extreme microSDXC UHS-I card that stays at the Moto G5 Plus maximum. Use it for media expansion and ensure the card is genuine and new from a reputable seller; capacity above this limit is unsupported by Motorola’s documentation.

- exactly within capacity limit
- Android-oriented current card line
- not for capacities above 128GB
- formatting can limit use in another device
Buying tips
- Buy microSDHC or microSDXC in 64GB or 128GB only; Motorola states a 128GB maximum for the Moto G5 Plus.
- A UHS-I card is the right interface choice, but a card’s U3, V30, or A2 rating does not override the phone’s own storage and performance limits.
- Back up files before formatting. Portable storage travels between devices; internal storage is encrypted for this phone and app support varies.
