Topmore’s TA-101 card, at 389 yuan (roughly 54 dollars), is possibly the cheapest route for adding an extra 1TB of storage to your tablet – and testing shows it isn’t as bad as you may think.
Many of the best microSD cards today aren’t super quick if you compare them with the best hard drives or SSDs. And that’s to be expected.
For example, theTeamGroup Elite A1 microSD card registered 92MB/s read and 87MB/s write speeds when tested via CrystalDiskMark in our review a few years ago. Similarly, according to the manufacturer, the Samsung Pro Endurance offers read rates of 100MB/s and write speeds of 40MB/s,
Not all cheap devices are bad deals.
Enter the Topmore TA-101 white 1TB TF card, which Chinese publication MyDrivers has branded the cheapest in the world. This is a TF card rather than a microSD card, meaning it’s a previous generation of technology but serves the same purpose.
Testing via CrystalDiskMark showed read and write speeds of 95.8MB/s and 93MB/s, respectively aligned with the manufacturer’s claims. This is ideally in line with many of the cheapest microSD cards, including the Silicon Power 1TB device, which has read and writes of 100MB/s and 80MB/s, respectively. This, by contrast, retails for $65.
However, crystalDiskMark results are a little different from judging performance in real-world contexts. When copying over a 100GB file, there were some dips in quality when assessed through HD Tune Pro, but the performance when copying over a 4K movie was relatively poor, with significant drops in speed at various points along the way.
While the TA-101 1TB is an enticing option, especially for its price, it may be worth waiting a while because Topmore has recently announced that a 2TB version is in the works. Although 1TB microSD cards are rare, 2TB versions are practically unheard of.
