Dope Tech Episode 2

<<@Fainthen says : So the write speed for collection of files are comparable to the sequential write of a decent HDD, that's not bad at all, there's some SATA SSDs that are slower, but then again, people shouldn't use sd cards and microsd cards for data storage, aside from on the go.>> <<@jessebooker2920 says : yo bob is fye 🔥>> <<@OrakKhan says : Subscribed just by looking at you>> <<@glbernini0 says : Why is the reader so huge? Bought one that size 15 years ago.>> <<@SquadGamersOfficial says : Today, as of 28/04/26 it cost £187.99- the SanDisk PRO-READER SD Express Dual Card Card Reader USB 3.2 Gen 2>> <<@kayoberlander6473 says : thank you, that was the same what i have found on information. We must wait for reader which will use the PCIe nvme protocol to get no transfer drop while copieng files (writespeed so in your vid). I have a device for gaming (ONE X player APEX AI 395 Max+ (16 Core-32 Threats / Radeon 8060S internal graphics). This device has MINI SSD slot for BIWIN MINISD by NVme technology (1700 mb/s). The reason to buy this is to play AAA Games in high or Ultra graph. setting without an external eGPU over USB 4 (40 Gps) and it perform very well. Sweetpot TPD setting is 40W TPD. But now with the nand microchip disater the price for this new storage (MINI SSD Card, a little bigger and thicker like a microsd card) is to high. I have bought since 3 months ago a BIWIN MINI SSD 1 TB Card for 160 USD without taxes (19 percent here in germany to pay from value). And since a few weeks the price for the same MINI SSD 1 TB is noe 300 bucks. 2 TB ( was 300 bucks before, now 500 bucks and over GPD shop 750 Euro without taxes). That was the reason to look for an alternative storage which is faster. The benchmark has open my eys. I copy my Steam library games to storage them on 2280 SSD m.2 and use an MINI SSD card reader from Biwin over USB 4 docking station (PULWTOP TB4 dockingstation) and it is very fast (internal copy in device from MINI SSD to 2280 m.2 (Gen 4x4) big games between 90 GB to 130 GB (maybe 60 to 80 seconds). I like this new storage type MINI SSD but nobody will buy a 2 TB BIWIN MINI SSD for 750 Euros, thats more than crazy. the price for PCIe M.2 are in an utopian pricerange soon if this wont will stop. Thank U, my questions are answered now after this video and demonstration in benchmarks (and in duing praxis - with the drop down to 200 mb/s, thats to low for me.) THX>> <<@tutacat says : SD express is used in high-end cameras (think 4K). Not sure about microSD variant.>> <<@tutacat says : Referring to "USB 3 Gen 2" is confusing if you include the "3.2 gen 2" because you have to ignore the .2 bit, because the USB-IF standard names are confusing. Please just say _either_ USB 3 10Gbps; or you could say USB 3 Gen 2. Realistically gen 2 means "3.1" originally", but USB-IF made this confusing because 3.0 is the same as 3.1g1 and 3.2g1>> <<@petebee2541 says : Chris could I run a linux distro from one of these?>> <<@MinaSmol says : This kind of SD card is actually an improvement of the Micro SD card.>> <<@sooowow says : Wait, did I understand this correctly, SD Express will fallback to UHS-I even in a UHS-II reader because the pins are slightly shorter on SD Express compared to UHS-II ?>> <<@diymyway9747 says : My unit operates on one slot at a time and this is what the red LED on one of the two slots means. You could have mentioned that!>> <<@thebrownbandit3925 says : Why was it so slow transfering from the pc to the sd express?>> <<@HaidarAL says : you missed out the comparison where you put them side by side and give us the information about what speed they ran in.>> <<@joshsmit779 says : I love your channel>> <<@randompoop1565 says : Thank you for bringing me back to 2000s with the latest tech😂>> <<@Greglaz125 says : What about the speed of 128 GBs?>> <<@jaycahow4667 says : As of November 2025 these USB-C readers seem to be out of stock everywhere.>> <<@damiand2480 says : Thank you big help that can use express card in normal sd card reader and dont have to buy express reader as bit expensive at the moment didnt know that use in nowhere tell you Now gonna do my test try nintendo key card games copy the data to pc and back see if I can preserve the data for the games>> <<@kashyapchodankar7568 says : I think they should leave backwards compatibility aside and design a new connector interface>> <<@RealBLAlley says : It seems like yesterday when my PC had twice the normal storage with its 120MB hard drive the size of a modern mini PC.>> <<@EvganyVorona says : SD ExMESS>> <<@FlyingFun. says : Read speed is amazing, write is just ok but I guess not going to need fast write very often. Heat is deffo going to shorten lifespan.>> <<@brendanhoffmann8402 says : SD cards are such a marvel. My new phone has a 1 TB (UHS-1) micro sd card in it. I'm so glad they still make phones that have them. It's a Samsung A25 5G.>> <<@farishanafiah8461 says : Can't even use any of them on smartphones, except Sony phones. If you currently daily drives a Sony phone, hats off to you Sir/Madam. You are a well-educated smart techie that vote with your wallet, not with popularity.>> <<@jeromeprin5668 says : why didn't everyone see it's a SHAME selling this Simple SHIT that price!! It's a kinf of trap when you have a switch 2, you've been had! ^^>> <<@hb1949 says : 02:52 says Samsung but it's Sandisk microsd express car being opened. Just a minor error I presume>> <<@chromerims says : First, the price is too high. Secondly, the SDA didn't anticipate the heat challenges, when they published the specs for microSD Express. So more credit to SanDisk for coming up with ThermAdapt. Sterling video, Chris 👍>> <<@johnhricko8212 says : "Weakest Link" department.... "Standards are great. That's why we have so many of them (...sez the marketing/sales department....)" Like USB standards.... clear as mud. Happy to see Jeff G. commenting on this.>> <<@s7evinshafe7 says : 2:00 and it still A1. we need A2.>> <<@olivesouch6423 says : 2:53 Correction: It's SanDisk not Samsung.>> <<@iraceruk says : All that plastic and other packaging for something as big as a thumb nail is absolutely terrible.>> <<@SrinivasKavuri-u4x says : which port the reader is connected to?>> <<@geirha75 says : those microSD cards are crappy. you can not trust them.>> <<@avon001 says : I'm interested to see some benchmarks on how this card behaves in a non-express system. Maybe it could sustain a higher read and/or write speed than other options, even though it's not running at is full potential>> <<@waatup says : Can you do a test on the backward compatibility of these sd cards? Curious what kind of speeds would they operate with a UHS reader>> <<@rogerstephenson5639 says : Outstanding video and very thorough testing. Thank you for all of the work that you do. I have been watching your videos for a couple of years at least.>> <<@honsbeek2 says : Yeah yeah blah blah blah blah very fast very expensive>> <<@jonathonearl482 says : Does this card reader work for any sd card or just the Express card?>> <<@LukePlayzIE says : I never need to rewind Explaining Computers videos to understand the content. Your articulate presentation style and restrained editing pace are ideal for me, personally. I have autism, and I prefer literal explanations and very clear and concise information. Thank you! This is also very informative regarding the current state of SD cards! 😅>> <<@LarryStone-q6r says : What if I accidentally swallow 1TB of data?>> <<@tromick says : 2012 Tech vibes... Wow... I am 16 again I guess. :)>> <<@juanmelendez3144 says : So walmart has a sandisk express 512gb saying "gameplay" and on the sandisk site, it says "microsd express" is there a difference between the 2?>> <<@idmhead0160 says : Storage manufacturers need to do something about all the stupid little letters and symbols they use to represent all this. I wonder if they could make it any more confusing?>> <<@nosuchthing8 says : Well this should be incorporated into raspberry 6>> <<@nathan-shearer says : Have you benchmarked the MicroSD Express cards in a USB3 and USB2 MicroSD UHS reader? I'm curious if they offer significantly better random IO performance on the slower card readers and if that will result in better performance for legacy systems.>> <<@audie-cashstack-uk4881 says : GameCube was the first ever or almost first ever device to be sd card compatible switch 2 was the first official express device>> <<@iordacheandrei7379 says : If I purchase it to use as an additional storage source on my Xiaomi 11 lite 5gNE phone, would I be able to benefit from its full speed or only 50% or less?>> <<@AlexandruVoda says : There are also UFS cards which also have two rows of pins. UFS is also comparable in speed but there are almost no devices and it is not backwards compatible. EDIT: UFS stands for Universal Flash Storage an independent standard, UHS stands for Ultra High Speed an is part of the Secure Digital standard.>> <<@NexXxus86 says : without dram cache you can't really hold the advertised write speed.>>
