Customer Ratings & Reviews

I am going all digital with my Switch library and this came out at the perfect time. The price is a little high but this is currently the only microSD card on the market over 256 GB. Definitely worth the investment to have all of you games installed on the SD card when you’re going portable.

A must own for Nintendo switch user well worth the price for game updates, patches, dlc and full game downloads.

Just buy this if you have a switch and download games. Fast and will not have to worry about storage again!

I travel extensively with my Switch, so I don't want to carry game cartridges with me - too easy to lose, and too much money to lose if they get stolen. With downloaded games, not only do I not have to physically transport them, I can just...redownload them if my Switch grows legs! But that means you need a big and fast memory card... This memory card definitely hits the mark. The Switch's microSD slot is the speed limitation, and it gives you TONS of capacity for those big games you downloaded over Christmas break at a reasonable-ish price. On a side note, I always buy my SanDisk memory cards from Best Buy. For something like this, the risk of getting a bogus/counterfeit card from an online seller is too high - I go into the store and buy off the rack, because BB has a trustworthy supply chain for store inventory.

Using this card as extra internal storage in a MacBook Pro for about 8 weeks now. Working reliably with normal use. It holds an entire iTunes and Photos library so it's accessed pretty heavily. No problems so far. Would purchase again.

Seems to work well. I use it for taking pictures on my Galaxy Note 4, and storage of audio, video files. Lots of storage space for the price. Great bargain and value. I don't really care about the speed, so I not paid any attention to it's performance except for the capacity. I would recommend it and purchase it again in the future.

I use this to store my entire music library, downloaded google play movies, pictures and I still have yet to fill up half of the storage. Formatting is the only downside as you only get about 366.76GB of accessible storage out of the product listed 400GB. Not sure why 33.24GB is wasted in formatting. That aside, I'm still happy this SD card turned my 512GB Samsung Galaxy Note 9 into an almost 1TB phone.

I've had many different to micro SD cards but this one is the largest and fastest I've ever had it works in my phone and my tablet and in my Chromebook. I would recommend this to everyone I only wish they made larger storage

Bought this on sale and great price for the storage it can hold. Use it in my phone and no issues so far. Fast read and write times and highly recommend it if on sale.

I got this card to use with my tablets. It has worked perfectly in my testing. Sandisk is always the memory card company I choose to buy as its quality is always good.

400gb is enough for me not to worry about storage for my Nintendo Switch. The read speed is good enough to play games.

Good capacity storage and as usual sandisk quality stands out. I use this for both my note phone as well as my Samsung tablet and so far no problems.

Got this on sale for $65 which is excellent for how much storage. Installed in my Nintendo Switch and works great.

I only digitally download games and I found myself running out of space too quickly with the 256gb micro SD. Upgrading to 400gb was a big help. Keep in mind, if you are planning to use this card for your Nintendo switch make sure you format it to FAT32.

For storage on the Nintendo Switch, it works like a champ. Plenty of storage and reliable.

This 400GB MicroSD card is the perfect card for you to use in your Nintendo Switch. We upgraded from our 128GB card to this and we are loving the space to download more titles (and DLC). If you plan on going digital with your Nintendo Switch, you cannot go wrong with this card. Between new game purchases and updates to your existing games, you'll see that you will fill up MicroSD cards fast!

I have a good workstation-class computer (HP Zbook X2 G4) but it has a smallish SSD (256 Gb). Luckily, it has an SD card slot so I was able to use this to expand my storage. Sure I wouldn't run programs/installs off of it, but it's good for storage of photos and working files that I need and I can keep the SSD for just the OS and program installs.

Look it’s 400gbs of storage. And getting it for the price I did was amazing (60$) so what I recommend (buy) is that (it) getting it (when) for your devices that have (its) an SD card slot (on sale) like your Samsung and your Switch (at least) it helps with the storage (once a month) and really didn’t break the bank (it’s on sale)

a lot of space.got on sale.if you can get it .get it.no 4k.

I got this as a gift, and I love it. 400 GB for either a phone or a tablet. I use this to store all my files from my tablet so if the tablet dies, the files on it will automatically be backed up. Great and secure way to protect your data and free up your device to store programs or data you don't need to back up.
