Bests & Worsts Reviews from Amazon

Let me get this out of the way first: I despise Sony's proprietary price gouging with a fiery passion. For this much money, you can buy a decent 120GB SSD. But I digress. This card will display 59GB when you look at its storage capacity on the Vita itself. I've included an explanation at the end of this review on why your card will read 59GB when you put it in. For those of you who don't want to read all of it, 59GB is what is displayed and this is not incorrect, nor is saying that it is 64GB wrong, it's just a common deceptive practice in today's digital storage market. This card, despite being a Japanese import, works just fine on American PS Vitas. What you are buying is a direct Japanese import, not a card that's been localized for North America. I'm using it on my NA PCH-2000 and I've played games from it, it works just fine. The amount of data on this card makes it a far better deal than all the other cards, and you'll never realisitcally fill this thing unless you're a Vita junkie and have a ridiculous number of games from PSN downloads. I put 5 PS Vita games (Borderlands 2 with all DLC, Gravity Rush, Uncharted, Soul Sacrifice, and WipEout 2048) and 3 PSone classic games (Front Mission 3, FFVII, and FFVIII) on here and it's only taken up 9GB of space. You can get by on the 32GB card, but I'd rather not have to worry about disk space, especially for a relatively minor increase in price comparatively speaking. Swapping cards is frustrating on PS Vita, mainly because it requires you to completely reboot, it's nothing like PSP. However, that's on the Vita's end, not this card's. An explanation on digital storage sizes: The card holds 64GB measured in metric units as opposed to binary units. What's the difference you ask? This is a fairly common practice that many people misunderstand. This thing will display 59GB to your console, despite the fact that it is in fact 64GB. Why? It's not because 5GB is allotted to "formatting" (it doesn't take 5GB to do that). 64GB is measured in metric units, meaning it is measured as 64 billion bytes, since giga- means billion. In computer architecture, measurements are based on binary units, meaning each power of 10 is actually 10 bits, which is 2^10 = 1024 Bytes = 1kB. Expanding this, 1MByte = 1024kBytes = 1,048,576Bytes, and 1GB = 1024MB = 1,048,576kB = 1,073,741,824Bytes in binary units. However, in metric units, 1GB = 1,000,000,000Bytes. The difference is then 1,000,000,000/1,073,741,824 = 0.931, so metric measurements allow them to display sizes that are actually 7% smaller. If you do the math, 0.931*64GB = 59.6GB, so it's 64GB in metric (what they write), 59.6GB in binary (what the computer reads). This is a common business practice and is how literally every form of digital storage is marketted nowadays.
