poor guy -- more comments on lighting than on excellent content. Linus, it was an informative video. I had already educated myself about this, but I really appreciate your making these videos. it saves me from having to explain to others. I just send them your video link.

[@rexodexo56]

Sir, may I ask how old you are? I'm just curious, as I rarely see as good comments as yours on KZbin and you also don't see older people in the comments section often.

[@BartSchuck]

+TreeSquared3 I'm in my 60s. I worked in IT for nearly 2 decades, have been a geek for 4 decades. now retired but still read extensively. I'm typically asked by people as young as 20-something all the way up to my peers regarding tech purchases, PC & Android issues and apps, and more.

[@rexodexo56]

+Bart Schuck Thanks for the quick and detailed reply! I'm only 17 myself, but it's nice to know that older generations are also present on KZbin ^^

[@BartSchuck]

TreeSquared3 keep learning. Keep an active, inquisitive, healthy mind. It will serve you well for decades. I've seen what happens to men my age that get mentally lazy. I don't watch tv & don't play computer games. Mind wasters!

[@rexodexo56]

+Bart Schuck Thanks for your advice! I very rarely watch TV nowadays, as I also think its a waste of time. Well, with video games you at least have social contact and you also have to use your brain- depending on the game

It's 2024 and I actually just heard about UFS first time ever on WAN Show. Didn't even know it's already in my not so new anymore phone (Note 9) which still displays its internal storage as "sdcard".

[@ultraali453]

[@togwam]

The top edge of the ufs cards remind me of shark fins for some reason

[@tennicktenstyl]

same. and pins are like.. I dunno, some sci-fi weapon-ish stuff. But wait, is UFS just like Micro SD but with more fin-ish design?

[@sl1ckk1ll3r]

+Bartosz Olszewski yes but different electric contact points so it functions differently ergo the way it would receive and transfer information would be slightly different.

[@togwam]

im glad im not the only one

[@PianoMastR64]

For some reason? I think the reason is pretty obvious.

[@mattizzle81]

yeah I thought that was maybe because they look like shark fins, but that was just a guess.

[@GoldenKingStudio]

Dual purpose slots would be extremely useful! Very smart of them. Honestly, whenever there is an innovation that makes prior technology incompatible, it takes so much longer for the new innovation to be adopted. It drives me crazy. Here is hoping Samsung can have a full sized SD card slot that would be compatible with UFS cards via adapter.

[@xpforevergaming8609]

I didn't even know UFS cards existed, I always thought of it as internal storage in phones/tablets/ ultrabooks etc. Never heard of anyone using a UFS card instead of microSD in their Samsung Galaxy S-lineup phones either...

[@Razor2048]

Netbooks are still very useful, they are cheap, and some are fairly decent. For example, I have a Lenovo S21e, which I mainly use for recording lectures, and taking notes. In NY, I am less likely to get robbed for a $125 netbook, and with improvements in IPC, the modern bottom of the barrel CPUs, still perform at about the level of the Intel core 2 duo P8400. You won't be editing video, or gaming on one, but if you need something that is cheap, and will handle Microsoft office just fine, then a netbook is decent. Best of all, since they are passively cooled, and and produce very little heat, you can even have them completely closed while at full CPU load inside of a laptop bag, and only hit around 65C CPU temperature, thus I can have adobe audition recording the lecture while I take notes on Microsoft word, have that sync to google drive, and then at the end, start the adaptive noise reduction filter, and have closing the lid not put it into standby.

It's interresting how nobody ever talks about the error rate & reliabillity of small flash storage devices. They often have very few backup sectors and very few error correction built in. And when they fail, unlike HDDs they usually fail completely, and all datas are lost, instant of just a few sectors.

Hey, Linus! I've got an idea for a TechQuickie or Explained. The history of BBSes, Usenet, and forums.

In addition to introducing it to younger audiences.

It’s 6 years later and I still haven’t found a good video comparing the UFS found in Android phones and NVMe found in desktops, laptops, iPads, and iPhones. Also, there’s still no market for removable UFS cards, 100% of it is still microSD. There aren’t any listings on Amazon for UFS cards. So much for that idea.

[@MRacer001]

it boggles the mind that you will soon be able to buy such a tiny card that can get relatively close to a desktop SSD, my very first SSD was a Crucial M4 SSD 256gb, the idea that i will be able to buy a UFS card which can get that close to it performance wise is frankly amazing. when UFS becomes mainstream i could honestly see desktop PC's using this as a storage option. now if only battery tech was moving forward at the same rate...

[@charleshines6155]

It is funny that you have shown iPhones when you said "as in a smartphone". The funny thing about that is iPhones never had expanable storage. It is a miracle that narcissistic Apple allowed the SIM slots. I guess they had to or they would be just another iPod touch which is very similar to iPhones.

[@xpforevergaming8609]

They'll get rid of the sim card slot soon due to eSIM.

[@denvera1g1]

need to make a mechanical 2.5 inch drive with a SATA expander on it and 2 of these UFS cards in it, so that on most modern laptops,even though you cant have 2 physical drives, unles you remove the optical drive, you can still have a boot SSD and the storage of a mechanical hard dirve

[@denvera1g1]

sort of like the WD black ^2 but instead of 2 physical drives that make up a single expanded drive with partitions seperating the SSD from RPM, it would show as 2 or more physical drives

[@Unborn8436]

The main reason developers don't run apps of off memory cards is because every single time you plug in a usb cable in your phone to your pc the card is unmounted from your phone, but what you said is also true.

So, it is the same size as microSD, will fit in microSD slot but won't work, requiring a new system with a new slot. That is gonna cause lots of problems and lots of "it doesn't work" returns. You really didn't think this through, Samsung.

Most of those tips are from the first generation of SSDs. Most are only going to hurt performance if anything on any near-current gen SSD.

[@2mo2time]

Thanks for the great info

[@imllendream]

One thing is the device processor, and another is the UFS/Micro SD port. How well are they gonna cope up to utilise the UFS speed to its fullness?

[@Tonatsi]

I wonder what would happen if you got these ufs cards, and crammed lots of them into an SSD sized box, and then set them up as a RAID (can't remember which number) and then added a bunch of sata connection ports to the side of the box, would we have our 20TB storage and extremely fast R/W speeds?

[@2ue]

I still have an sd card with 500mb that was huge back in the day...

[@Lukenallen8]

first USB gets changes with type c, now the most accepted storage medium is being replaced? I wish they would have made it the same dimensions as micro SD so that itll fit in sdcard adapters and your existing electronics.... should take about 10years until it takes over like micro USB type B vs mini b and micro SD vs whatever that other standard was...

[@ripp102]

They are the same fit, but it's another tech altogether. They are not compatible and it would be stupid to do soo. If you ask me why? the answer is performance and you reduce the cost of developing a controller that accept both. Samsung decided to do that with the note 7, i but that cost a lot.

[@Lukenallen8]

joker102 im aware of that however they could have played the pins out and made them compatible with existing slots instead of doing what Samsung is doing, I know this would cause confusion with which card is which but a small print could solve that

[@amshermansen]

Not necessarily possible to do...

[@Lukenallen8]

Mansen I'm aware if that, there's completely different requirements for the contact pins, I just wish more development was done on micro SD to minimise the bottleneck of the micro SD standard and to keep backwards compatibility with existing devices. However that's more of a dream as I know that's not exactly possible using the current specifications of micro SD

[@Goodmanperson55]
