Bought the Samsung Evo Select 512GB microSDXC UHS-I U3 during Amazon Pre Black Friday sale. The sale is from Amazon.com, but it is available on Amazon.sg as well.
I got it for S$75.52 with free shipping to Singapore since I am an Amazon Singapore Prime member. The usual price is about S$120 on Amazon, and on Lazada, it is selling for S$174.99.
After much research, I think the Samsung Evo Select 512GB microSDXC UHS-I U3 is the most value for money microSDXC card for the Nintendo Switch.
The specifications are the same as the Sandisk Memory Cards For Nintendo Switch which is UHS-I with Speed Class 3 (U3). That gives you a read speed of up to 100 MB/s and a write speed of up to 80 MB/s.
A SanDisk 512GB microSDXC UHS-I-Memory Card for Nintendo Switch retails for S$117.21 on Amazon.sg which makes it 40% more expensive than the Samsung Evo Select 512GB microSDXC UHS-I U3.
The only downside is you don’t get the cute prints of the Nintendo Switch on the microSDXC card. But when the card is inserted into the Nintendo Switch, you can’t see the design anyway.
