Amplim is another one of those many white-label memory card companies. We are not sure where they actually get their cards from but they manage to sell quite a few of them and if you see them on sale sometimes they can be tempting.
The Amplim 667x A1 would not work in our Sandisk UHS-II USB-C memory card reader. It is the only card that wouldn’t work and is likely why it has been discontinued.
We were able to benchmark it in another reader though.
Amplim 667x A1 V30 Review
USB-C read speeds came in at 99.6 MB/s which is very good for a UHS-I card, but the write speeds only came in at 52.2 MB/s which is a little low compared to the competition.
The A1 rating gives this card a small cache and often these types of cards work great when it comes to running applications.
| Card Name | USB-C Read | USB-C Write |
| Amplim 667x A1 V30 | 99.6 MB/s | 52.2 MB/s |
Compatibility
The Amplim 667x was rated at V30 which means it has a minimum write speed of 30MB/s, This is great for most mid-range 4k video cameras that shoot in the 200Mbps range.
For stills photography, the card performs a little below average and it shouldn’t really be considered because of those compatibility issues with Sandisk Readers.
Reliability
Discontinued.
