are we ready yeah are you sure you ready for this actually hold on a second let me just let me just fix well no you don't it's it's already set I said before we did anything I think so you don't have to change oh right this one no no oh oh okay you know what I just forget it I'll just I'll host it you you operate the camera let's just go back to the very opening things what's uh what's this video about again nice t-shirts Oh at all right now I remember why you're doing this okay let's go cooler masters casemod World Series is your opportunity to show off your modding skills and win great prizes entries close February 7 to 2015 click now to learn more hey guys what's up Brandon here so SD cards they're boring right Linus officer thought so but they're way more exciting than you probably realize mine's changed no okay fine but on to my actual point SD cards are one of the most important things I personally use on a day to day basis and while I get some flack for the number of them I've collected over the years like if I didn't have them I wouldn't be able to do my job so learning about them for me was a worthwhile investment and I'm going to share some of that knowledge with you guys to start with we need to demystify some of the confusing numbers and letters associated with the different classes of SD cards because there's a lot of them class 4 class 6 class 10 uhs-1 UHS 3 does your brain hurt yet let's break it down each of these numbered classes represents an increase in the minimum write speed in megabytes that our card can handle with UHS one and UHS three two noting the most recent ultra high-speed cards recently there's been a lot of hype about consumer devices that can shoot 4k video and 4k support and SD cards which is why the UHS 3 standard was introduced and is the focus of our video today does it matter do I need a UHS 3 card to shoot 4k video well I wanted to know one I also wanted more SD card support so I asked Linus if I could put in a few sample requests and he said uh yeah I guess as long as you do the benchmarking on them so I did I ended up with nine cards in total and I ran a number of different benchmarks including crystal dis mark as well as some real world testing on a Canon 60d SLR and our lovely Panasonic gh4 which is a 4k 30fps capable camera these two cameras will be amongst the most demanding cameras that can run on SD cards with the higher performance options like our fs700 requiring SSD or proprietary media something that you can see in this video here so how did we do well the numbers speak for themselves most cars performed in crystallises mark as expected within the range of their rating benchmarking was done in an msi gs70 with the built-in card reader which I used out of convenience when I observed its results were pretty much identical to the one we were getting with the standalone Kingston USB 3 reader now crystal dis mark is only a synthetic benchmarking software and those numbers are not necessarily representative of real-world performance where other factors like camel former can come into play so onto our real-world tests for the gh4 test I shot multiple 30-second and one minute clips on each card the first clip is in 4k at 30fps shooting at a bit rate of a hundred megabits per second the second clip is in 1080p at 30fps shooting in a very stressful bitrate of 200 megabits per second I was astonished to discover that every single card in our roundup worked perfectly with the gh4 I did a combination of static shots with a slow pan and tilt with each card when playing back the footage in Premiere none of them had any drop frames moving on to the Canon 6d test I shot 30 raw stills per card using the burst shooting mode here are my camera settings to give a visual representation of this I recorded audio of the shutter during the test the audio bunch that you see here are the 18 raw still that can be taken within the cameras buffer and every spike after that is the following picture leading up to a total of 30 to my surprise the sony card came in the slowest in this test even with its higher read/write speed compared to the lower end a dated and kingston cards with sandjas cars taking the win with very solid performance in the shortest amount of time so conclusion time is one SD card really better than another yes is it absolutely necessary to have a UHS 3 card for 4k video the short answer seems to be no for now while only half the cards in this test are classified as UHS one they all managed to have high enough speeds 10 all the 100 to 200 megabit bit rates of the gh4 s recording modes but in future cameras we might see higher support periods and you need to be careful to get the card that can handle the right speeds to match it should be noted that if you're shopping that read speeds are far less important than still only coming to play when ingesting footage that you've already shot something that is rarely the bottleneck with our workflow so thanks for watching let me know what you guys thought of the video if you enjoyed it if you want to see me talk about tech on the other side of the lens more like I said he would pay for me to go to nab this year so please leave lots of honest feedback under the video I really want to go to NAB so even if you hated it you probably should tell him that you loved it and all right all right all right all right all right all right all right yeah just getting pathetic over there so guys like he did say though please do leave comments if you enjoyed Brandon's first on-camera appearance ever he really is our resident expert when it comes to this stuff and we really appreciate you guys watching this video we also really appreciate our sponsor Dollar Shave Club Dollar Shave Club is the way to get inexpensive high quality shaving supplies delivered directly to your door for only a few bucks a month it's available in a variety of territories including the say Canada and New Zealand and their pricing is extremely reasonable basically just factoring in the additional costs associated with well you know shipping all these different places and adjusting for the currency of these different regions now they don't just have razors they've also got shaving cream they've got well shouldn't say cream because it's more of a butter it goes on clear so you can see what you're doing they've got their aftershave and they've got their then this is always a fan favorite one wiped Charlie's which are peppermint scented bought wipes for men visit dollarshaveclub.com slash Linus to sign up and start shaving time and shaving money it's one of those things shaving time and shaving money I get flack from you guys when I do the shave time shave money thing and when I do save time save money I feel kind of bad because their slogan is shave time shave money even though it's a bit of a cheesy joke but they're kind of cheesy guys actually very good guys anyway you guys are good guys to like it if you liked it dislike it if you thought it sucked leave a comment if your feelings are more complicated than this which I'm sure they probably are given we like did a hosts swab here on you out of completely freaking nowhere as always guys check the link in the video description you excuse me you can buy a cool t-shirt like this one you can give us a monthly contribution where you
