Huawei Nano Memory Card Review: The FUTURE of phone storage explained! [Mate 20 + P30]

Hey it's Alex Pimentel it's central and today it's time to talk about nano memory so everyone knows microSD right there's been a trend away from expandable storage in many Android phones over the past few years but a lot of big names including Samsung and LG still ship with that all-important SD slot that means you can easily upload photos music podcasts anything that might take up a lot of space on that precious internal storage the problem is in smartphone engineering terms this tiny SD card is actually pretty huge not just in terms of the size of the slot but also the space it

Takes up with the contacts on the PCB so Huawei solution has been to shrink down SD storage even further for all practical purposes all a nano memory card is is a microSD shrunken down into the footprint of a nano SIM card as you can see here the physical size is identical but the gold contacts on the back are a little different right now nano memory is only supported on a handful of high-end huawei phones that mate 20 May 20 + May 20 Pro it's very likely it'll be supported in the upcoming p30 phones as well the way it works is pretty simple

The second SIM slot in these phones doubles as a nano memory slot you can see here marketers mmm so in dual sim models you can either use two sims or a single sim and a single nano memory card it's not a whole lot different to the so-called hybrid slots in some phones right now which can take either a second sim or a micro SD only of course this approach takes up much less space inside the phone and by the way an Anna Marie card will only work in a second slot if you put it in a sim one slot it won't be recognized nano memory cards are currently on sale in China as

Well as the UK on Amazon right now your only real options are 128 or 256 gig Huawei branded cards with up to 90 miles per second speeds and surprisingly these are comparatively more expensive than the same spec of microSD you are paying for that miniaturization afterall and Huawei says it'll open up nano memory to other vendors for free but who knows whether it'll actually take off among the Samsung's or LG's of the world for now this is very much a huawei only accessory you're buying Huawei's card to use in your Huawei phone if you're not using a second SIM in your mate 20 it's

A relatively inexpensive way to double up on storage 128 gigabytes is a water downloaded Netflix or podcasts or music and on the phone like the mate 20x in particular with its enormous screen it's actually a great fit in terms of speeds the 128 gig card that Huawei sent us approached but never quite met the quoted max speed of 90 Meg's per second in sequential reads and writes we saw speeds of around 60 Meg per second read and atmo per second writes rather than read and write speeds fell to between 13 and 14 megabytes per second any case that's more than fast enough for most

Things that you're going to be doing on a phone when I use a card like this in a phone I'm not loading apps onto there mainly it's just a place to store music and podcasts and maybe a bunch of photos so they're not eating into the phone's internal flash so this is basically just a smaller version of something we've had for years in the Android world but it does at least show that there's one manufacturer out there thinking about the future of expandable storage in a phone check the link in the description to buy the 128 gig nano memory card we've shown in this video which I'm

Using in the mate 20x right now that's it be sure to subscribe so you don't miss what's coming next from Huawei at Mobile World Congress and beyond thanks for watching and I'll see you next time
