Maybe you shouldnt use card readers you got out of a cracker

The Mymemory (and elsewhere) virtually the same name product but with a "80MB/s" on packaging is a much slower one for the 4k read/writes. This one is the "90MB/s" is the much better performer for all four tests and you identify this specific integral one with this description
Integral 64GB Ultima Pro 90MB/s Micro SDXC U1 Class 10 product code of INMSDX64G10-90U1
It is not just the 90MB/s headline figure is important, this one is also very reasonable for the 4k read/write. Tested using USB 3 port to a "4 portTecknet USB 3 powered hub" in Windows 8.1 64bit OS with a USB 3 memory card USB adapter. All kit along the benchmark path need to be USB 3.

Good price for Ultima Pro.

I am buying given the very good test results below, despite I do not need one.

Such a fast card at £10, cannot go wrong, maybe I just upgrade some of my relatively slower cards.

Great price

great post and heated up :smiley: .....just got a tonbux mxq android box off amazon and was wondering if this a good card to use with additional media on it to play through the box on the goggle box....such as 1080p video and 320kbps / flac audio files? thanks for any sound feedback in advance :smiley:

Does anyone have any experience, if this will work with Sandisk Sansa Clip+ MP3 player?

Was the 'Bad experience' when they told you that MB/s and MBytes/s were different?

They are one and the same. You're thinking of Mb which is 1/8 of a MB.

MrPud is correct that the card doesn't meet Class 10 (10 MB/s) writing standards. It's actually a class 8.

More likely he mixed up his micro SDXC and used USB 2 somewhere along the data path such as a USB 2 memory card USB 2 adapter (as I never had a fake one from Amazon, Mobymemory, Mymemory, 7dayshop, etc. and I don't buy from eBAY unless it is one of those shops) as anyone buying from eBAY unknown seller should NEVER post benchmark here due to fakes.

Good spot & thanks for the code SAVOOSD

That person tested a different memory, read my post above. In a nutshell, this family of "90MB/s" models is very good performer. Here are the product codes that have this level lof performance http://www.integralmemory.com/product/ultimapro-microsdhc-microsdxc-90mb-class-10-uhs-i-u1-memory-card?quicktabs_product-tabs=fourth#quicktabs-product-tabs
Notably this latest new family "90MB/s" has no 128GB version so the Inergrals 128GB on sale now are from different families,

Read my comments above, look carefully at that benchmark that Geezer put up, it is not even 64GB as a starter for ten.

That looks much better, especially the random access is impressive. And the price is excellent - if only it wasn't mymemory...

Been using them for years, not a single problem with them at all, very good service even for once in 2014 when a wrong memory was despatched but resolved promptly to my satisfaction. Must have spent hundreds of pounds with them over the years. With these barebones onlines sellers, cheap and qualitystuff, you gotta be ready to take it on the chin once every few years, basically save buckets of cash with their bargain prices but be prepared to write off bad experience one or twice over the years.

Acording to their website, this family DOES include a 16GB variant.

See my post #16 above, that's what I typed an hour ago at 18:09 (your post was 18:40 too late).

Thanks heat added and purchased with 3% quidco. Cheers

What are the performance differences between this and the Samsung Evo plus, however tiny they may be??

Great price! Got it for £9.49 with the promo code SAVOOSD

Will this work on a galaxy s5??

I have Integral UltimaPro X U3, speeds at 65/77 write/read.

Your results are more correct for the UltimaPro U1.

The other person's results clearly has something wrong.

Yes, good random speeds.

I only have Sandisk Extreme U3 to beat it in both random write and read.

Having said that, if only used to store movies, random speeds is not that important for this purpose.

Taa, bought some. Every little helps.

Both MB and MBytes stand for Megabyte(s) - so what exactly are you on about?

Are you having a bad experience or something?

I've just read some of these comments and its like reading a script from 'The Big Bang Theory'

Not needed, but ordered none the less. Thanks op and thanks for code.
Damn you hotukdeals!

Many thanks OP.

Price has increased to 12.85

Received mine yesterday. Tested with ATTO disk benchmark but I only got 22MB/s write speed. Not bad for the price but no where near 40MB/s as previous people posted.

I received mine today. It is the correct product, product code of INMSDX64G10-90U1.

I used quite few programs to test. Most of them return max 20MB/s write.

I also verified the whole 64GB, constant 20MB/s write throughout.

My test equipments are fine. I have some U3 cards can get to 74 write, 93 read on the same equipments.


How did you get 45MB/s write?


At £10, 20MB/s is not bad.
But I would be must better go for today's Sandisk Extreme 64GB U3 card at £15. Much faster card.
Or the 7dayshop 64GB write 29MB/s at £11.

I only bought it to upgrade based on 45MB/s write and I do not need extra cards, 20MB/s write is slower than any cards I am currently using. Completely defeated the purpose what I bought it for.

Yeah, code is the same on the packaging.

All test equipments are USB 3.0, they did not limit the results as they can get up to a lot faster than your results on some of my U3 card.


I am returning it. It is no use to me at 20MB/s write. The one I want to upgrade by this card is not slower than this one.

Could be your USB controller, but here is ATTO in exactly same hardware test environment, I am getting 25MB/s to 27MB average Write using ATTO tests.

46 down to 25 is a big drop.

The other person got 22.

I got slightly less than 20.

Nowhere close to 46.

I also got 20 or so write and 73 read on an inbuilt sd card reader. Presumably usb 3.0 given the read speed and the fact the laptop has usb 3.0 ports.

Good for my purposes - upgrading from transcend 300x, for capacity only as speeds similar, but clearly not 45.

Yup, just tested mine. Consistent 78/20 MB across the board with both ATTO and CrystalDiskMark. I also picked up the 128GB from SanDisk which quotes 80MB/s from an earlier offer and ran similar tests: got a much better 80/40 MB/s.

Dunno what Splender was testing, but definitely not this Integral rated as 90MB/s.

I've had my card for a few days, and the performance has been terrible. My Moto G 3rd keeps complaining that the card is corrupted after a few hours, which means scanning/fixing on a PC. Trying it in my Lumia 830 causes the handset to crash after a few hours, when it reboots it states that there is a problem with the card...

Testing in my PC, using a USB3.0 built-in SD reader, I can use the card without it corrupting, but writing to it is painfully slow. Even my old slow Sony branded 40MB/s card is faster.

Integral 64GB 90MB/s
