Give up 100gb and spend 1/3 the money. This is the one I have in my lite and it’s been great so far:

Hey, just a general heads up, I see that in a few other responses you've mentioned getting the 1TB card for a really cheap sale price. Always be wary of that. 1TB micro SD's are relatively new and as such are never cheap. For reference, a 400GB is about $65.

512gb to costly. Look for the Sandisk 400Gb I got on Amazon for $53 as the 512Gb is $100.

Surface Pro can go 1 or 2? TB.

Delete some shit you don’t play and buy that shit online. Or get an SD card off amazon. This one is particularly inexpensive.

You’re an adult. “Muh storage” is no longer a valid excuse for exposing yourself and others to this shit.

I would personally cancel and go with Clove because not only is it cheaper but you also get a free pair of headphones which you can just flip on ebay for an easy $150. That's a big difference in price vs wonda. When you consider the amount you can get for the headphones you're going to end up saving $230 USD assuming you're in the USA. And all you are getting is an extra 128GB on a phone that has expandable storage... lol

256GB is only useful if you are installing tons of games or other heavy apps that need to run off your phone. Otherwise just take advantage of the phone's microSD support and get a nice big card. $60 for a 400GB card on amazon right now...

Oh, I was wrong it is 400GB not 512GB. My phone (Samsung S9+) has 64 GB internal storage and then I inserted a 400GB microSD card in there too. I set PocketCasts to use the microsd card so it doesn't store downloaded podcasts on the phone's limited 64GB storage at all.

This seems to be a reliable one. Will still test it before I put anything on it since fakes get mixed up even with legit markets due to warehouses and huge counterfeit market.

Believe it or not, microSD cards can come in any capacity. That they follow the powers of two (doubling every time) that you've pointed out is due to convention. Here's an example of a 400GB microSD card. So there's no absolute reason that it has to be double the last. However, if you look carefully on that page you'll notice a 200GB microSD card and that should give you an indication of what might be going on.

When it comes to hard drives, microSD cards, and what not, there's an internal geometry to how the circuits are arranged. This underlying geometry is what dictates the "platform" the actual SD card or whatever is built upon. So let's look at something.

   C
 . |
R- #

So let's say we have the above memory cell represented by the hashtag. There's a C for column line and a R for row line that selects it. Now how the actual selection goes that's a bit detailed, but in this case, if we wanted to address that memory cell we would send (C, R) coordinates.

 12345678
1########
2########
3########
4########

So let's say we have the following memory layout. We have here (8 x 4) memory cells which is 32 memory cells. If I shrink that memory by a factor of two (which is usually what the target for shrinking cells is) then in the same physical size I can now fit two of these. And I'll add a "page" selector.

p1 12345678   p2 12345678
  1########     1########
  2########     2########
  3########     3########
  4########     4########

So I've now double the size. But let's say I shrink that by a factor of two again. Now I can fit double the previous. So twice the previous is equal to four times the first.

p1 12345678   p2 12345678
  1########     1########
  2########     2########
  3########     3########
  4########     4########
p3 12345678   p4 12345678
  1########     1########
  2########     2########
  3########     3########
  4########     4########

So if I shrink that by two I'll gain double that, which is eight times the first. I'll just squares at this point to represent pages.

._._._._.
|1|2|5|6|
._._._._.
|3|4|7|8|
._._._._.

Okay. But now let's head back to the first one. And this time the underlying platform, instead of being 8, we're going to make it 10.

 123456789A
1##########
2##########
3##########
4##########

So here I start with 40 as opposed to 32. So if I shrink that by two, I can fit twice as much, and thus you would then get 80, 160, 320, and so on...

Companies design the geometry they'll build a platform on from a pretty early point and they tend not to really want to mess with that design unless there's a really good reason. Additionally, a shrink of a factor of two is just a typical goal. If they can shrink more and the platform will fit nicely in that value, then they'll select that. Power of two sizes are usually selected because they fit nicely with a shrink of two. But a platform that is built with say a geometry of 10 would also fit nicely within a shrink of five, since that's a factor of 10. But a shrink of five might be harder to get to so might only do that with some limited platforms.

Hard drives, SD cards, and what not do not HAVE TO be a factor of two, it's just that it's a nice one to work with because shrinking by two is typically the minimum bar. And so a platform with a geometry based on two, gets selected early on in the design phase. But it's not an absolute requirement.

Now people might use powers of two as THE REASON it is the way it is. And there's a good reason for that too. RAM is always a power of two. That is because RAM is tied directly to the CPU and without having to get into how memory is addressed and used by the CPU, a factor of anything other than two would massively slow down everything. However, hard drives and other things like that, like SD cards, aren't tied directly to the CPU, so delays between the two in addressing aren't as apparent as with say RAM. Some people will confuse that requirement with RAM with the same in other types of memory not tied to the CPU, but if it's not tied directly to the CPU, then you can select any size for the underlying geometry of your disk platform.

So why even have the 200GB and 400GB platforms? It boils down to the "cross the line first". Hard disk makers have quite a few platform designs to work with. If they find they can take their factor ten based platform to a shrink of two and everyone else is having a problem with shrinking by two 256GB to 512GB, then they might go ahead and shrink their 200GB to get 400GB and be first person to cross the 256GB line. When everyone catches up and we're solid in the 512GB and everyone is pulling their hair out trying to get to 1TB, they might figure out how to shrink their factor ten to 800GB and be first to market with something post 512GB. It's all a bit of marketing gamble on if they'll do that or not though. If it's been quite a hot minute since the 512GB started, it might be worthwhile to see if shrinking by two the 400GB will work.

Again, the shrinking by two is also just a picked number. It's the factor to shrink by that most makers feel is "worthwhile". But it could be a shrink of 1.75, 0.8888, or whatever. Heck you might even have someone that might not release till they get a shrink of 5. It's all up to the makers. But a factor of two seems to be the factor that a lot of makers like to hit. And since you shrink by a factor of two, you always double the size. And that is why you see that doubling.

​

EDIT: I also noticed that you would like to know a bit more about how computers work. Might I suggest Ben Eater's 8-bit CPU build. This video series covers logic circuits and some very fundamental building blocks of digital circuits in a very easy to approach manner. His video series uses all of that knowledge to eventually build up to a working 8-bit CPU with very, very basic I/O on a seven segment display. He also has a series on the 65c02 platform, which dives into the realm of looking at hardware and how assembly instructions interact with the actual hardware and begins getting into arithmetic algorithms on that hardware. And yes, you can actually buy all the breadboards and ICs to build along with the video series as each video gives you a parts list should you want to do so for yourself.

Torn between two micro sd cards, advice for better choice?

My unpatched switch is on the way and I'm trying to get everything ready. For the micro sd cards the two are SanDisk Ultra 400GB MicroSDXC UHS-I Card with Adapter - SDSQUAR-400G-GN6MA,Red or the Samsung Electronics EVO Select 256GB.

I like the idea of more size but the U3 speeds from samsung appeal to me and I wonder how noticeable the nicer write speeds are in effecting day to day switch hacking/gaming activity. I appreciate any advice or help I can get! Thanks!

As long as you're not going to be taxing it too hard IO-wise (primarily using it for warm/cold storage, not running VMs or games off of it), you can get away with a UHS-I Class 10 SD card. I've gotten this one twice in the past as it goes on sale frequently.

I have a quad that i bought direct from iflash a year ago, and it works flawlessly. 6th gen running Rockbox. I dont play FLACs though, only mp3.

​

This is the exact SD card i bought for it:

I have two other iflash adapters (all bought direct from him) and they all perform flawlessly.

You mean Sandisk Ultra vs Extreme? The main difference between the two are their read and write speeds - upper and lower limit. For the Switch, the Sandisk Ultra is more than enough with write speed of UHS-1 U3. Even the official Nintendo Sandisk Micro SD cards have the same speeds.

Using a "slower" card on the Switch not noticeable in real world scenario. And the Switch also caps the speeds at 100MB/s. So getting a Micro SD card with maximum write speed above that is a waste of money.

Ummm... the same amount? 25,000.

That’d be 25 petabytes in one milk jug for $6.475 million. ($259.99 per card)

But if you bought 400 GB cards at only $57.99 each, you could buy 44 petabytes for the same price. You would need 5 milk jugs though to hold the 116k cards.

Honestly any Samsung or Sandisk 128-400GB SD card should be fine, depending on your budget and how many games you want to put on it. I buy most games physical, but since a lot of indie titles are eShop (digital) only, I eventually bought a 256GB one. They've gone down in price tremendously; a 400GB microSDXC card will only put you back $65 with shipping ( https://www.amazon.com/SanDisk-400GB-microSDXC-Memory-Adapter/dp/B074RNRM2B ), while 256GB is only $40 these days. 400 GB cards seem to have the best GB/$ ratio these days, too. Overall, I've found Sandisk to be the overall cheapest high-quality brand for microSD cards, and they've served me just fine.

That said, if you're going full digital, a 400 GB card is definitely something I would recommend over 256, as there are games that are well over 15 GB each, even Nintendo titles.

32GB should be fine at the start unless the physical games in particular require a large download. Most physical games do not, though.

But yeah, eventually you will probably want to get an SD card. I recommend seeing how fast you fill up the internal storage to decide how big of an SD card you need.

I recommend either the Sandisk Ultra or Samsung Evo Select SD cards. Just make sure that they’re being sold by Amazon.

> Do I need to buy another joystick or if not a serious gamer the two mini ones that come with it are more than enough?

The included controllers are fine! You just may find that larger controller would be more comfortable, but it’s not at all necessary. Definitely wait and see how you like the comfort of the included controllers before deciding if you want to get a different one.

> How often is the console release cycle, every few years or undetermined? I wouldn’t want to buy the current console if another is coming out soon.

Nintendo’s consoles usually last at least 6 years. I don’t expect a new console for at least another 3 years.

We could get an improved version of the current Switch, but we have no idea if that will happen and it would not make the current model obsolete anyway.

> Is Animal Crossing as good as it sounds? Heard people rave about it.

It’s good, but it’s definitely not for everyone! It’s not quite like most games. I recommend checking out this post if you want to learn more about what the gameplay is like.

> Presume it’s best not to buy the Switch Lite since you can’t display on TV right?

If you want to use the Swirch on the TV then it’s definitely best to go for the regular Switch if you can afford it. The Lite is a good cheaper option but that’s a pretty big feature that it’s missing.

I don’t think there are any special features with Apple TV
