TEAMGROUP is a Taiwanese manufacturer, founded in 1997, that makes a range of memory products — including RAM, SSDs, thumb drives, SD cards, and — of course — microSD cards. They also sell some PC accessories such as cases, fans, and CPU coolers.
Their products seem to come up fairly frequently in my Amazon searches. An anonymous donor sent me a set of the TEAMGROUP High Endurance 64GB’s, which caused me to ponder about what else they had.
This one made me thing of the Kingston Canvas Go! Plus — what with having “GO” as part of the name — which made me think that this was TEAMGROUP’s high-performance option. Looking at what they have available, it looks like that wasn’t the case — they have a few options that advertise better speeds — but this one boasted 100 MB/sec read speeds and 90 MB/sec write speeds — which would be impressive if it managed to pull them off.
It did not, in fact, pull them off.
It did, however, score in the bottom half of all cards I’ve tested so far for performance:
| Measurement | Percentile Score* |
|---|---|
| Sequential Read | 20th |
| Sequential Write | 35th |
| Random Read | 29th |
| Random Write | 45th |
* As of March 1st, 2026. If you’re not familiar with percentile scores, think of them as “this card did better than X% of all cards I’ve tested”.
DISCLAIMER: I’ve only tested one sample so far; these results are only representative of how that one sample performed.
This card bears the U3, V30, and A1 performance marks; the measurements I got weren’t good enough for it to qualify for any of them. (The U3 and V30 marks require sequential write speeds of at least 30MB/sec; the A1 performance mark requires random read speeds of at least 1,500 IOPS/sec and random write speeds of at least 500 IOPS/sec — none of which this card was able to achieve.)
On the endurance testing front:
- Sample #1 has not yet reached the 2,000 read/write cycle mark. It is expected to get there sometime in March 2026.
- Samples #2 and #3 are still in the package, waiting to be tested.
