I've been using Samsung class 10 micro-SD cards with Raspberry Pi's for a while. I used the Samsung cards because I find them rock solid reliable, I have never had one fail, and they perform as claimed. I nearly exclusively use 32GB cards, as the extra space provides plenty of room for the wear levelling algorithm.

I've tried some other brands in the past. I've had some fail within 24 hours. I have had some corrupt data. I have had quite a few that perform no where near the speed advertised.


Much to my horror, the main distributor, Ingram Micro, has decided to cease distributing them. Now I need to find a new brand. Anyone got a brand of class 10 micro-SD they would care to recommend?

Not sure if what you say affects this but oneday.co.nz quite regularly has good deals on the Samsung cards, I got a 32gb from them for around $50 give or take.

Don't use SD cards if I can avoid em myself, as I prefer eMMC, have you looked into that?

Perhaps off topic, but I'm finding Odroids to be a much more attractive options than the pis. Build in gigabit and four quick cores...

Ingram will do that... perhaps another disti has picked them up?

Otherwise I'd probably suggest Sandisk or Transcend (some ram will use Samsung chips). I don't like Transcend 2.5" drives, but their ram was very solid.

Because of the high number of counterfeits in the market, I'm too scared to buy one when the price looks "too good to be true". Samsung have a 10 year guarantee on their cards. The counterfeits look almost exactly the same, but often fail within 12 months or corrupt data when you read it back.

I've looked into eMMC, but it's not possible. I've looked at the Odroid's before, and they do look good. I like to use Ubuntu, as everything is the same across all my platforms then (server, desktop and raspberry pi), and the raspberry pi is an officially support platform.

Odroid's seem more popular with people who like to run Android (aka software developers).

I don't believe AData sell 32GB class 10 UHS-1 micro-sd cards. They do sell lower spec slow micro-sd's - but I want class 10.

Why not order from overseas? Torpedo7 had a special on Samsung 32GB recently, so they should have some.

I use mainly Apacer cards in my cameras and have never had a problem, but writing JPGs in a camera is pretty light duty use.

I've tried searching across our quoting system across all NZ distributors, and nothing else comes up. I've also tried emailing our account managers at several, but nada.

I've read very mixed reviews of both Sandisk and Transcend, so I am luke warm on them. The fact that Samsung give you a 10 year guarantee on their cards speaks volumes to me - that is a very long warranty for anything in the IT storage field.

I wish I had that option. Alas no.

Ah, stink. That's it in a nutshell though, what hold's Odroid back is their biggest strength; to keep up with producing mint hardware, official support and line continuity becomes scarce.

Fair point that I hadn't considered.

Come on, it's just an SD card. Do you need recommendations for your 2-ply toilet papers too?

When you spend days setting something up from scratch you don't want to loose it and have to start again.

Would this do? https://m.1-day.co.nz/products/AFJBAN4WA I have a 64 in my phone. Seems pretty good.
I also have one in my wife's phone. First time she has never complained about the memory card.

Not sure if the waterproof bit changes anything.

I've been using Sandisk cards for years and not had an issue. Could recommend, not sure if that's a brand that is counterfeited though.

Up to 1/3 of all the micro-sd cards in the market are counterfeit. So when I see someone like 1-day offering them for half the normal price, and they don't say where they got them from, then I think it is probably too good to be true, and they have been sucked into promoting someone selling the counterfeits. It's gotten so bad some of the major sites like eBay have posted warnings about the cheap counterfeits.

Some of the fakes are really hard to spot.

Correction I have a 32, logically that means my wife does also. . Lol. Memory always makes things bigger than they really were...

Looking at your links for how to confirm legit? It matches the description of the valid item.

I don't recall it being the program you mention but I have 16 gb of music on it that got there with surprisingly little write time.

They do. RRP = $19.09

I have a collection of lexar,sandisk and strontium class 10 32gb micros. A sandisk one is the only failure within months. Came from a special at Repco.

I have found the Strontium the worst so far. I haven't had a single Strontium yet when I can write a complete image out (so write to every block on it), and then have it pass a verification when I read the image back (so it corrupts the data with no errors, and gives you bad data when you read it back).

Don't put anything no a Strontium if you actually value the data. You wont know you have a problem till you try and get the data back off.

I also found Strontium performs up to 10 times slower than the claims on its pack. This is doing a best case 32GB sequential write.
