Discussion

When I first started searching for SD cards on AliExpress, I decided to sort by price from lowest to highest — and Hiksemi was a result that came up near the top of the list. At the time, they were selling the 8GB card for just $0.01 — but that was before shipping. Still, I have to say that it’s a pretty effective strategy for getting people’s attention, and the card is still an excellent value even when factoring in shipping costs.

Honestly, though, I have to say that I was pleasantly surprised by Hiksemi’s cards as a whole. This card’s only speed class marking is a Class 10 mark, which it easily qualified for. Sequential read and write speeds were well above average (with sequential read speeds being towards the high end of the spectrum). Random read speeds were average (with sample #1 being above average, and samples #2 and #3 being slightly below average), and random write speeds were all above average.

Endurance is where these cards have really shined. As of the time of this writing:

  • Sample #1 has survived 54,635 read/write cycles without any errors — far more than any other card in my collection thus far. It has also gone the longest without errors out of any of the cards in my collection, having gone nearly-continuously for 299 days without experiencing any errors. And, it’s also endured the most bytes written out of any of the cards I’ve tested so far, at 400.91TiB.
  • Sample #2’s first error was a 32-sector wide corrupted data error during round 3. However, it did not experience any further errors until round 5,918, when it began to experience a large number of missing data errors. It reached the 50% failure threshold during this round, and the test was considered complete at that point. Below is a graph showing this sample’s progression:
  • Sample #3 has survived 14,219 read/write cycles and also has not experienced any errors.

Overall, would I buy this cards again? Yes! It was a complete surprise to me, but this card scored above average in every category. The only downside is that it seems that they’re no longer available at the price point I bought them at — there are other sellers on AliExpress that are selling (what appears to be) the same card, but by the time you add in shipping, the price ends up being between 3-6x what I paid.
