clickbait video full of trivial general knowledge spread over 10 minutes of your time, shame

The A1 standard is not for standard continuous write/read speeds. The A1 rating is for RANDOM write/read speeds (IOPS). This is important for smart phones uses where you put app data on the sdcard and it needs to go from reading and writing small files very often. Recording video requires fast continuous read/write speeds. The U rating or V rating is the continuous read/write rating (like recording/ playing video). U1 is 10 MB/s minimum, U3 is 30 MB/s minimum. U1 cards will work for 4k recording but at lower bit rates. If you want to record 4k at higher bitrates (100 Mb/s) you will need a U3 card. Also when testing the speed of the card, they can be deceiving. Empty cards are much faster than nearly full cards due to the controller needing to find the empty space to write the file, thus the minimum speed rating on cards.

That was a long SanDisk pre-roll advert, when does the content start?

Anonymous thumbnail for a non-conspiracy informative video, seriously?

[coolvideoish]

I remember when 4gb micro sd cards cost $30, and had read/write speeds of under 3mbps.

[kyliefan]

YES!!! BOYCOTT eBay for SD and micro SD cards!! Junk and eBay doesn’t really care to kick them off for selling garbage!

What you really overlooked with the higher numbers on the box for these more expensive cards is as follows.
Let's say you buy one to put in your phone, or your camera - you go on vacation. You shoot a ton of photo's and video's and when you get home, want to offload them to your laptop/desktop whatever.

Have fun with offloading 256GB at 10mb/sec read speed of a cheap card. It`ll take you 10 hours.Or even worse, having a card with 5 mb/sec write speed that you wanna fill up with media (movies) for on-the-go with your laptop.

Whilst a phone's internals aren't high-bandwidth enough. In other scenario's where you need to offload, or load data in bulk on an SD card or MicroSD card. Doing so with a USB3 card reader you can get some great speeds and it's not so "theoretical" anymore.

That's why a lot of photographers choose the fastest cards for their camera's - especially those on the clock if you're shooting events/sports and need to offload 64GB + a.s.a.p to your laptop, minor edit and send it off to your buyers before the other one can.

"Loading times" will be shorter not "faster". It's the loading that's faster, not the time. ;]

1 The buffer is probably the RAM of the device unless it's specified otherwise which could be in some cases increased to give a boost in performance at the expense of some RAM for the time the software needs it.
2 A faster card by its own doesn't make your videos look better, but allows you to increase the bit rate rate yourself(preset or a direct bit rate setting) which could make your videos look better assuming space isn't an issue and the maximum quality level achieved by the sensor hasn't already reached with lower quality settings anyway, and unless cameras have an auto setting for setting the bit rate themselves according to the speed of the card(which is not impossible but also not very likely) they simply just won't effect the quality of your video.
3 Some internal card reader controller chips of many phones will not be able to utilize the max speed of all cards due to their specs.
4 Some times higher bit rate can cause a less powerful device to heat up and throttle, and the bit rate wasn't set to being constant but rather variable then the camera software will reduce the bit rate automatically otherwise it will other look laggy, distorted, corrupted and it could lead to software crash of either the app or the entire phone requiring a reboot, probably corrupting the video or photo files and in extremely rare cases damaging the card itself.
5 Cards like all storage expect very few exceptions store data in blocks which could be specified when formatted to a certain file system like FAT, FAT32 etc etc. The blocks must have certain sizes according to the file system and their sizes or the sides of the files you write on them which help can help read and write speeds significantly.
So now you know better.

For laptops with the capability to mount a 2.5" HD/SSD inside, I'd reccommend two things. The first is an external 2.5" hard drive PURELY for use as a complete system backup drive. They come up to 4 Terabytes, so you WILL have enough space on one of those...just choose one larger than the total space ALL of your system's HD's and SSDs add up to, and you're set.

The second is a Seagate Ultra Slim 2 Terabyte 2.5: HD. Why? Because the drive within the enclosure is a 7mm high drive, which means that you CAN get TWO TERABYTES of storage on your laptop...as long as it's got the capability to fit a 2.5" drive inside.

Sure, cracking the drive out of it's enclosure WILL kill the warranty, but every time I've ever had to deal with Seagate for a warranty repair/replacement, they've ALWAYS said that "it's not covered" so they effectively only offer warranties until you NEED to make a claim. Even two months after purchase is too long for them.

Anyway, hope that helps someone out there. d=O)

Absolutely right on the money! Done the Aliexpress and Ebay purchases. The amount of trouble they go to. Artwork on packaging is almost identical. However just flip over the Micro SD card to see the ID and there is a telling tale right there. I bulk ordered from a US Camera outfitter. No worries mate.

[jessecannon]

i know i am one of many but i was wondering where you got your phone stick you were shooting footage with

[MinimalistGuy]

Thank you everything that you said was such an inspiration.
When working and travelling you need masses of batteries (so I have 11 and three charging cases, also a 24000 mA Solar charging Power Bank)
I have the 200 GB Fast SanDisk and it is great value and brilliant.
The quality of your videos is incredible, well done.

[NeoSlashott]

You saved me... I almost buying the wrong SD Cards that's hard to choose. Now I know what I want to buy a certified one best. :)

[StarDarkAshes]

I don't see why they don't just make a 1 TB phone already. With 4K it's totally reasonable to have one terabyte on your phone. Why are they so scared to add more gigabytes to it? 256 it's like not even very good.

[RUS-dvsm]

At first I thought why you are making this video :P Then after watching it, it is definitely useful info for those who are new to SD cards.

Since we prefer to view streams of relatively similar images (motion of objects in space) rather than epileptic flashing randomness frame by frame, wouldn't it make the buffer's job easier to first copy all similar/identical pixels from within a certain border of the previous frame, and go from there? Worst case scenario, every pixel is different.

E bay has a lot of fake sd cards that say 64GB but after 8gb everything is corrupt

[coilsmoke]

Yes...That is one jam packed busy day you are slugging thru. God only knows when you will get a break.
