AliExpress Choice XrayDisk MicroSD Cards: They’re legit!

So… we’re back and here’s the results of the testing of the AliExpress Choice MicroSD Cards. These were XrayDisk-branded, which has been a good brand with some SSDs I got from them in the past.

Surprisingly, they are genuine and unlike the fake 256GB/512GB KRY-branded MicroSDs some time ago, they actually have a good read and write speed which is always a plus.

Tests were performed on the cards using HW2Testw to verify if the cards were faulty or showing a fake capacity. Let’s get on with the testing!

The 64GB MicroSD Cards

The 64GB microSD cards came pre-formatted with the exFAT filesystem, which is a interesting change from the usual FAT32. Anyway, here are the results of that write and verification test:

This is very respectable for genuine cards. Write and Verify speeds may not be the fastest, it’s better than the first experience I had with the KRY branded fake 256/512GB cards… which never really surpassed 9Mbyte/s for the Write and 11 Mbyte/s for the Verify speeds despite them being Class 10 and UHS 1 “certified”.

The 128GB MicroSD Cards

The 128GB microSD cards came pre-formatted with the exFAT filesystem, much like their 64GB sisters. Here’s the write and verification results on the 128GB ones:

Both 128GB cards checked out fine. Speeds were respectable, no other observations worth mentioning. All tested MicroSD cards are rated for Speed Class 10, A1, U3. Whatever that means…

Conclusion & Should You Buy?

I’m satisfied with my purchase and surprised at the quality. I paid less than $30 AUD in total with free shipping to get these MicroSD cards. They’ll be good to slap into something for extra storage in a hurry.

So, yes, I would recommend them for short-term storage. No, I would not recommend them for the long-term. I’d recommend a better brand like genuine SanDisk or Samsung. Especially if you’re planning to use them in a device like Valve’s amazing Steam Deck portable console.

The reason why I say no to the long-term storage is the NAND quality – you don’t know if it’s going to be reliable or die within a short time frame.

With that all said, thank you for reading this review and I hope it was useful. I’ll catch you again soon.
