Reddit reviews Samsung 128GB up to 48MB/s EVO Class 10 Micro SDXC Card with Adapter (MB-MP128DA/AM)

I would suggest not doing what you are asking.

Keep the SD card you have. Get a USB drive. They're half as much, and you can add on to the space you already have.

Here is one that is ~$28. Compared to ~$55 micro SD Card..

If you keep your current card and get a USB, you would have about 160 GB of space combined. It will also save you $20.

In my personal experience, I went from a 32 GB card that was supported and worked great, to one step up to a 64 GB (same model, just a larger size). For whatever reason the card can't read continuously, which causes pausing while browsing and stuttering during PS1 movie intros. I ordered two of them, and both have the same issues. I did lots of testing, Pi 2 and Pi 3, 2 different 32 GB cards and 2 different 64 GB cards. The 64 GB cards just had issues with reading and occasionally writing. There were never errors, or bad writes, just delays which can cause pausing. Putting the PS1 games on a USB drive solved that.

Edit: If you're using all the ports on the Pi, then upgrading the card might be less of a headache.

I've used these 128G Samsung [Evo Select] (https://www.amazon.com/gp/product/B01DOB6YW4/), [Evo] (https://www.amazon.com/gp/product/B00P3NMVVU/) and [Evo+] (https://www.amazon.com/gp/product/B00XJKL1ME/). The only catch is that Windows 10 (and probably 8.1?) won't format anything over 32G as FAT32, so you'll need a 3rd party utility to do that.

I've had similar issues with microSDs corrupting themselves. So far I've had the best luck with a Samsung EVO 128GB. It's been in my 650 since October 2016 and I haven't had any issues with corrupting disks since I replaced it with that one.

Very hard to tell.

Ask if you can put a file to test if it's actually 128gb, and preload a 64+GB file onto a hdd/flash drive, then transfer it there with him.

And maybe try use diskpart to clear and format with him watching.

Edit: probably fake. Look at the amazon ones packaging; http://www.amazon.ca/gp/aw/d/B00P3NMVVU/

It would be about $107 cheaper for the samsung listed here or $100 cheaper for the Sandisk. So about $100 for 128 GB instead of double that, plus 32GB onboard. http://www.amazon.com/Samsung-128GB-Adapter-MB-MP128DA-AM/dp/B00P3NMVVU/ref=sr_1_2?s=pc&ie=UTF8&qid=1427386463&sr=1-2&keywords=128gb+micro+sd+card

Using this 128gb Samsung microsd. Works perfectly fine

I'd bet twenty bucks that card is counterfeit as shit. Look up the 128GB version of that card on Amazon and compare the pictures.

• The "256" and the "EVO" on the eBay card are in a slightly different typeface than the 128 card.
  
• The top of the "128" is aligned with the top of the "EVO" text, but the "256" is smaller and just kind of splatted on there.
  
• The 128 and below come with SD adapters, the 256 doesn't?
  
• The 256 doesn't list the capacity on the hang tag at all? Even the 32GB announces the capacity in a gigantic Helvetica Neue-esque. 256GB would be a Big Damn Deal™, you better believe they'd not be subtle about it. Maybe even Helvetica Neue Bold.
  
• The 256GB card is the same price as the 128GB? Considering the price differential between 64GB (~$35) and 128GB (~$100), that price, or anything near it, fucks the curve right to hell.
  
  Unfortunately, counterfiet SD cards and USB thumb drives are a thing now. They'll show up to your OS/camera/device as the size stated on the tin, but if you try to put that much data on there, stuff just gets overwritten. It sucks. The card in the auction may not even be 128GB. Could be four.
  
  Edit: Wanna start your own counterfeit ring? Here you go. Look at that thing. Not even close. The Samsung logo isn't even quite properly formed or kerned.

there's a sale on samsung cards on amazon

  Needing more than 128GB of media on your person at all times is a niche use case, but even for people who do - OTG flash drives exist to allow people to supplement their storage space to watch movies/TV shows while traveling or whatever without requiring them to purchase a phone that has a microSD card slot. Considering restrictions on adoptable storage and 'move to SD' functionality, it is better to have a large pool of main storage instead of being forced to rely on a microSD card right out of the gate due to an anemic amount of internal storage.

Sorry- this one then?

Don't get me wrong, I'm actually a big proponent for large and fast internal storage. I'm just saying that 128GB as an option doesn't come cheap and a microSD slot remains a far more affordable alternative. I would've preferred to see 64GB as the base model with the move away from expandable storage but I'm not surprised they didn't.

But yeah, for half the money you could throw one of these into a One M9 and have 160GB total. There are faster cards for around $5 more that do sequential reads faster than a Nexus 5 or S4. They're improving quite a bit.

You're not going to like the price haha
This.
Is.
Quality.

Samsung doesn't make a 128GB card.

EDIT: My mistake, it comes out next week - http://www.amazon.com/Samsung-128GB-Adapter-MB-MP128DA-AM/dp/B00P3NMVVU/ref=sr_1_13?s=pc&ie=UTF8&qid=1417481609&sr=1-13&keywords=128+gb+micro+sd+card

First of all, make sure to double check that none of your pre-existing devices have one. If not, I go by three pillars when finding a MicroSD: Price, Capacity, and Brand. Best capacity for the least amount of money- but with a trustworthy brand like Samsung or SanDisk and good reviews. I personally think This one looks pretty good.

I've have this Samsung 128GB micro SD for over a year now in my 32GB MXPE. It's unmerged and I keep all my videos, podcast, pictures, and music on it. I currently have about 50GB of videos. No problems so far, but I backup my data every 2 months or so.

I prefer SanDisk Ultra https://www.amazon.com/SanDisk-microSDXC-Standard-Packaging-SDSQUNC-064G-GN6MA/dp/B010Q57S62/ref=zg_bs_3015433011_1?_encoding=UTF8&refRID=EMB8XFRBVS080VQV20JP&th=1

or Samsung EVO https://www.amazon.com/Samsung-128GB-Adapter-MB-MP128DA-AM/dp/B00P3NMVVU/ref=sr_1_1?s=pc&ie=UTF8&qid=1485895630&sr=1-1&keywords=samsung+evo+128g

I use this one. Fairly cheap for the size. Especially since it's a Samsung, not a garbage off-brand.

i paired one of these:

with one of these:

the write performance cant compare to a PCIe SSD, but the read is terrific. i highly recommend it.

I bought a 128gb Samsung SD and whenever I had it in the tablet, turning on the screen took a few seconds longer. I looked this problem up and apparently its only for cards larger than 64gb.

Also, I was advised to only use the stock charger so as not mix up the voltages or something and my complaint is that the stock charger cable is short (a little under 2 feet).

Other than that, I haven't encountered any issues, but you should remember that I haven't used it for anything other than MXPlayer/Twitch.

EDIT: Also, the "cast screen" function works perfectly, but I elected to use Bubble UPnP because my TV didn't stretch the "cast screen" picture.

Also, there are no physical buttons so sometimes I would accidentally screen shot with my left hand and that was annoying.

Did you get the Evo or the Evo plus variant?
