128gb MicroSD Cards

Do you guys have a brand preference? I'd like to see a head to head:

Samsung 128GB EVO Micro SDXC up to 48MB/s with Adapter (MB-MP128DA/AM)

http://www.amazon.com/Samsung-128GB-Ada ... DA%2FAM%29

SanDisk Ultra 128GB UHI-I/Class 10 Micro SDXC Memory Card Up To 48MB/s With Adapter- SDSDQUAN-128G-G4A [Newest Version]

http://www.amazon.com/SanDisk-Ultra-UHI ... Version%5D

Lexar High-Performance microSDXC 633x 128GB UHS-I/U3 Flash Memory Card LSDMI128BBNL633R

I need something to christen the Pi2? Pi 2? Pi Tau?

It's clearly called "circumference" from 2πr (rearranged as r.π.2).

I like that.

Anyways, has anyone used a 128 GB SD for this? If so, which one? I'm on a bit of a budget, so I'd like to get it around $40 or so if possible. I've seen them for as little as $16.99 ( http://www.ebay.com/itm/161471284810 ), but I'm not sure that this would work, so I'd like to get one that someone can verify works with the Circumference.

For my Pi2B server (which is called Apollo) I found a 150GB SATA hard drive and bought a USB2.0 carrier for £10. I'm still convinced that spinning chromium is better than SDCards and there's lots of money to invest in a 128GB SDCard. Here in Rightpondia they cost about £40 ($60). Any ones you've seen on eBay for under $20 are probably Chinese fakes.

It's too much of a gamble forking out for an expensive sd card. Those cards are not designed for the usage profile they get from running an OS, they're intended to write large blocks of data very rapidly, not do loads of I/O of small chunks of data. Exotic cards have been problematic with the Pi in the past and it's common knowledge that class 4 & 6 cards can give better performance on a Pi than class 10 - google will throw up loads of hits on the subject.

I too am looking for a 128gb microSD card for my new pi2. I really like the form factor/profile of the pi without any USB peripherals plugged in and I currently use a 128gb SD card for my original pi with RaspbMC. So upgrading is super easy.

I took a risk with a "SanDisk Ultra 128 GB microSDXC UHS-I Class 10 Memory Card with Adapter up to 48MB/s Read (SDSDQUAN-128G-G4A)" from amazon and it didn't work.

I don't really want to try a dozen cards before I find one that boots. Are there any that are confirmed to work on the new Pi?

Did you realize that cards >32GB tend to be formatted as exFAT, instead of FAT32. The PI expects a FAT32 partition to boot from, and if its formatted as exFAT it wont boot. Read the "pitfalls for beginners sticky" for details.

$16.99 looks like way too good a price for a 128GB (as in giga bytes) SD card.

I would not be surprised if it actually was a 16 GigaByte card, "mistakenly" marked as 128GB instead of 128Gb

It was a cloned image from an existing, and working, RaspbMC installation so it retained its FAT32 formatting. In addition I installed the latest Raspbian distribution on it, still didn't work.

Just in case, I just checked its formatting and it is indeed FAT32.

Does your existing 128gb card work in the pi-2? If so then why not get one the same?

Are you aware that Raspbmc isn't compatable with the pi-2 so you can't do a straight copy of your existing system?

the pi2 has a microSD card reader, my existing card is just an SD card.

Is that so? I will have to do some research...

I'm giving a sample. (sorry if i'm wrong) 128gb mini sd can be connect with usb adaptor. Can be better for compatibility. Need small microsd for boot. Other data can be install over usb data. ( installation like usb flash disk )

High quality usb microsd adapter can be give better performance result when compared pi's default microsd slot.
I cant using enough English language. My writings can be wrong grammer.$
