Samsung 8GB class 4 Micro SDHC card review

Samsung 8GB class 4 Micro SDHC card reviewThe good folks at MemoryCardZoo sent us out a Samsung 8GB class 4 Micro SD card, figuring we might quite like to put some of its bold claims to the test.

Reviewing a Micro SD card would normally be the kind of chore that’d drive a sober chap to booze, or a drunken chap to even more booze, but this Samsung effort reckons it can laugh off a fairly brutal beat-down. Fun times.

Claim the first: the Samsung 8GB class 4 Micro SDHC card is waterproof and dust-resistant, thanks to its EMC (Epoxy Molding Compound) coating. Bit hard to test the dust stuff (though, having said that, my flat could probably use a good spring clean), but the water stuff; that we can do.

I left the Samsung 8GB class 4 Micro SDHC card in a mug of water overnight, and it was completely fine the next day. Indeed, some of the marketing blurb claims the card can live in seawater for up to 24 hours.

Claim the second: the Samsung 8GB class 4 Micro SDHC card is shock proof. The Samsung website suggests it’s ok to step on the card, but I gave it a good kick around the flat too. Again: the Samsung 8GB class 4 Micro SDHC card was unfazed.

Claim the third: the Samsung 8GB class 4 Micro SDHC card is “safe amid x-rays and magnets”. Er, I don’t have my x-ray machine to hand, but I did introduce the card to a few of my favourite fridge magnets. They got along just fine, and the Samsung 8GB class 4 Micro SDHC card walked away unscathed.

I joke about x-rays, in the sense that it’s not exactly easy to test out, but the practical example Samsung gives is x-ray machines in airports.

With write speeds, you’re looking at 6-7MB/s, so just over 20 minutes to fill her up.

The Samsung 8GB class 4 Micro SDHC card goes for £10.50 with free delivery from MemoryCardZoo and comes with an SD adaptor and five-year warranty.


  • Water and dust-resistant
  • Shock proof
  • Magnet proof


  • Not the cheapest 8GB class 4

Summary: You can pick up a less durable 8GB class 4 Micro SDHC card for a good few quid less, but this might be what you’re after if you happen to be particularly clumsy.

It's pretty amazing to think that this tiny little thing can store so much yet be so durable. In fact, the first thing I do when I finish building my time machine is go back to the 80s and go "Hey look at this super-awesome technology guys!".

I wonder what would happen if you microwaved it Lewis? Though that might be a tad dangerous...... We're Mobot, not Mythbusters :)

My micro SD cards tend to be quite safe as they're usually tucked inside my phones (where they dont come out)! (_;)

Do yuou know, ive never thought about the xray machine at an airport messing up the data on my iPhone/Camera? Its not had any problems so far and its been through a fair few so I wonder if thats so much of an issue and more marketing jargon?
