Silicon Power 1TB Superior Gaming Micro SDXC UHS-I (U3), V30 4K A2,High Speed MicroSD Card with Adapter, Design for Steam Deck, ROG Ally and Nintendo-Switch

Used in two RetroPie and they work great and at a great price

I bought this initially for $80 in mid-August. Now it's about $65 >.>Anywho, this sd card is amazing. I specifically got the "Game" version of the SD card, compatible with game systems like the Steam Deck and Switch. It's an A2 card with faster read/write speeds than A1 cards, like the SanDisk Ultra for instance. Loaded it up on my Switch and half is full already which is a good sign.Read and write speeds float around 30-35mb/s from testing via h2testw on Windows 10. Tested ALL of the available space, so I can vouch it's an authentic 1TB card.Installation is very simple. Just plop it into the card reader on your device and it shows up automatically. This surprised me since previous cards wouldn't be detected so easily.Something to note. You will not be using ALL of the 1TB card. It's merely a metric of measurement for SD card manufacturers to round it to a more appealing number. Think of it as marketing.Realistically, you'll be getting 923GB instead of the marketed 1,000GB's. So, "IT'S A SCAM" am I right? No, I'm actually not. The rest of the storage capacity is used for storage memory since you'll be inserting and taking out 923GB's worth of files constantly. That's normal and it happens with every other sd card size. 400GB cards for instance, you're only getting 366GB available.There's also the fact some devices measure storage units differently. An example, my card shows 665GB available while on my Nintendo Switch it only shows 620GB.It's practical and necessary for the most efficient use of the card.History Lesson:There have been prototypes of 1TB cards in the works for years, but it never became finalized. At least it hadn't until 2019 when the first ever 1TB SD cards would reach the market from both Lexar and SanDisk respectively. This was a large leap over the previous highest, 512GB cards.You can imagine the price, right? $100? $200? $350? It was actually priced around $450-$500 initially. Think about that. $500 for a 1TB SD card.And in 2023, this is the first time these cards have dipped below $100 making them very affordable now. $80 is already an excellent deal, but for $65? That's an immediate buy!As for this card, would I recommend it? Absolutely. It's fast, efficient, and about 15% of what they cost 4 years ago.Thanks for reading :)

Update 6 months later:I still haven’t had any issues with these (my main use is in iFlash adapters), but with other brands that have larger usable capacities (Samsung) inching closer to the same price point, I opt for larger capacity cards more often even if they are still 50% more expensive. But I still buy this brand a lot and will continue to do so. I wish there was an agreed upon standard for SD manufacturers as to what actual size qualifies for each stated capacity.~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~I've gone through around 35 of the 256gb cards, 12 of the 512gb cards, and 2 1TB microsd and they've all worked just as they should. It's still a small sample size, and they format to a slightly lower storage space than other cards of the same labelled capacity, but it's a negligible amount for the price, which is something on the order of 30-50% of the price of the major brands (Sandisk, Samsung, PNY, etc).I don't feel like I'm sacrificing reliability for the savings, either. They're microSD cards, and inherently fragile so they'll all break eventually, especially if theyre subjected to lots of insertions and removals. My use for them is more or less permanent storage that's rarely written to, and so far so good.

Gives enough space

Do not buy for ALLY or steam deck!!! It makes the system act weird and you can’t install any games to it. They will always try to download then give error messages no matter how you format it. The quality is bad

I purchased this for my Steam deck so I could expand its memory and it works perfectly. It’s a really great price and it delivers of more space to same games and also speed when loading games. Don’t be put off by the cheaper price, this things works great.

My son bought one of these cards for both him and me I wasn't even aware my phone would use this size but it is fantastic it's a beautiful little card put it in my phone it was very easy to install and man did it work fantastic moved all of my photos and everything freed up tons and tons of memory in my phone and still has lots and lots of room on it of course I've bought the 256 gig and can't say enough about it this brand is a fantastic brand and have had no problems with it neither has he he uses his for his computer and gaming devices and it's very very affordable and it's a brand that we will buy again so yeah give it a try we're happy with it

This item, 2-pack of 256GB micro SD cards would've been given five stars, however, one of them gave me problems in my Samsung Galaxy phone where the phone couldn't detect it and I was forced to replace it with a different micro SD card. So far, the other SD card is working OK in another Samsung Galaxy phone I keep as a backup.
