Memory card prices have been hitting crazy new highs lately
I was pretty shocked by the new pricing while scouting for a high-value card for a client
I just had to write a post to commemorate a second-tier brand reaching such a high price point
The card I picked this time is the
TCELL MicroSDXC UHS-I (A2) U3 512GB Surveillance Memory Card
It’s guaranteed for 3000 P/E Cycles (Program Erase Cycle), which is actually a solid performance for TLC flash
Simply put, this is a HIGH ENDURANCE memory card
It’s perfectly fine if you want to use it for a dash cam
Just a heads-up: double-check the maximum capacity your device can handle before buying
Even now, plenty of devices still max out at 128GB
No surprises with the packaging—it's the standard blister pack shown above
It comes with one MicroSD card and one adapter
All the speed-related info is printed right on the MicroSD card itself
It meets UHS-I U3 and Video Speed Class V30 standards: This means the minimum write speed is 30 MB/s
App Performance Class A2: If your card reader is powerful enough, it can hit 4000 / 2000 IOPS
Let's do a quick reality check
I’m using a Kingston Media Reader USB3.0. [cite_start]It’s a bit old, so the speeds might lag slightly behind the official claims
But surprisingly, the gap was very small
Read: 94.21 MB/s (Official figure is 100 MB/s)
Write: 89.24 MB/s (Official figure is 80 MB/s)
IOPS data is below
The basic performance is actually better than the ADATA card I picked up previously
ADATA High Endurance microSDXC UHS-I U3 A2 V30 128GB Quick Unboxing
However, which one is more durable remains to be seen
I'll leave this post here for now and update it with a "closing box" report once the card finally dies
