SanDisk 1.5TB Ultra microSDXC card + SD adapter up to 150 MB/s A1 UHS-I, Class 10

It depends on what you want to use it for, but as an archive mechanism, any SD card is a bad idea. This will be most likely aimed at being put into a Switch, where the price of a failure is just mild irritation at having to reinstall games

Not if you still use a phone with a card slot....

OneDrive can be extremely slow, especially if youre using the interface in windows file explorer. On big downloads they throttle the connection too and if you want to view files it may download a whole video, before you can view it (on your throttled connection). The online app is more efficient if youre sorting as it streams it but still clunky. (I find onedrive limited my connection to 4mb/second even though my connection can do 33 download)

Local storage will usually be much much faster/cheaper long term than the cloud. But you do need to factor in a backup for your most valuable data (the cloud doesn't tend to fail)

The external hard disks you have could be good as a back up. You may want to get something like a new 2tb external 2.5" hdd which can hold a lot. Small footprint. They go up to about 5TB without needing a separate power cable. Via USB you'll get about (70-130 megabytes/second continuous read or write)

Alternative if you want top speed and budget isn't an issue, you could have an external SSD drive, either m.2 stick in an enclosure, or dedicated external SSD or a drive with a external SATA cable. Speeds via USB can go up to (500+ mb/second, potentially thousands)

The sd card like this is very compact but can be unreliable as so much chip is in such a small space and it can generate a lot of heat and die, or its easy to break. They're great for unimportant data though and local copies in a device.

A NAS may be excessive for your needs. They're best for people needing lots of storage or multiple people sharing a server at different times. Think small business work server or video editors with lots of footage, or more commonly now personal media server (people collecting tons of movie/tv series files etc.) Those devices can run programs too.

Look at diskprices.co.UK for some of the best offers on drives, sticks etc. EBay also has good deals occasionally (edited)

Me too it's nuts how that much storage can fit into that small space!

What has that to do with microSD cards which you use for phones, Nintendo switch etc...?

Raspberry Pi builds never had it so good

That's why I've never uograded since the Note 20

That'll be 64GB not TB.

I got a 17.2GB HDD when I was a student (pre millennium) so I could copy cd's. *duplicate backups of ones I legally own, obviously...

Yep. I wonder what 20 years down the road will be like, justTeleport will be beaming my kebab to me, I'll be plugging an aerial into my ear to work from home. Dfs will still have a sale on, sports direct will still be carp. And France will be on strike.

Already outdated though ... Petabyte blurays are already a thing.

Who's storing important data on a micro SD card for any period of time? Best application for these are games in purple devices, so data loss really doesn't matter.

Ironically you don't need to spend all this money to expand your memory...

Yes, the Switch supports microSD cards up to 2TB.

The problem has always been commercial application; The HD TV was about during the 70s but didn't hit mainstream until late 90s. Now, with UHD, 4K etc it makes sense these cards will become standard in a few years.

I was thinking the same with tho mobiles will it only see 1tb or not work at all ??

Dont buy one then 🤷🏻‍♂️

She agrees with you

Get the Corsair mp600 core mini 2TB for £10 less at scan. 

I hope you have all that data backed up. Just because it hasn't failed yet, doesn't mean it won't ever.

Lucky you, you can make this problem 7x worse now.
