Would be great if I could just roll back whenever I wanted to the prior System update if I enabled something like that in settings (it would use more storage though)

It... moreFirst off when it comes to this, I'll take the space savings over having two OS images on the phone's storage. The update times aren't that long, and even when it's an OS upgrade I have my Note 20 Ultra set to just check for and install updates when I'll be sleeping. I've only actually seen one update install and that was when I manually checked for updates. The rest of the monthly security updates have all happened while I'm asleep.
Second to the guy talking about SATA SSD's and what not. You're def right that the NAND itself is the most expensive part of an SSD.
Just to be clear though phones do not use a SATA interface for their NAND storage. Nor do they use PCI-E. They use an industry standard called UFS or Universal Flash Storage.
It gets revised over time to be faster. UFS 1.0 for example maxed out at 300 MB/s. UFS 2.0 maxed out at 1.2 GB/s, and UFS 3.0 and 3.1 are up to 2.9 GB/s. UFS is actually closer to a interface like SCSI in terms of how it functions than it is PCI-E or SATA
As for a Samsung SATA SSD's being ~$30 more than a Crucial, I'm sure a small part of that is paying for the name (Samsung is one of the most well-known, and trusted SSD manufacturers, but Crucial is great as well). But you gotta really look at the details when comparing SSD's. Not just the Read and Write speeds they advertise the most which are just the sequential read and write speeds. IOPS (Input/output operations per second) are just as important since they reflect the speed of random reads and writes which are more common. You're computer will be dealing with the reading and writing of lots of little files instead of one big file far more often than reading or writing one single huge file (which is what the sequential read and write speeds are).
Doing a quick compare of the cheapest Samsung 1 TB SATA SSD and the Crucial 1 TB SATA SSD. They are very close in specs. The Samsung has a slightly higher sequential write speed than the Crucial (530 MB/s vs 510 MB/s) and higher Random Read performance (98,000 IOPS vs 95,000) while the Crucial has slightly higher random write performance (90,000 IOPS vs 88,000 IOPS).Also the price difference on Newegg is $5 more for the Samsung and the difference on Amazon is $10 more for the Samsung.
So it's not like Samsung is charging a huge premium just for their name (at least in the SSD market). Samsung and Crucial share one BIG benefit the smaller players in the space don't (like Western Digital, Seagate, X-data etc). Both Samsung and Crucial manufacture their own NAND memory (and sell tons of it to those smaller brands) and both manufacture RAM which SSD's have a varying amount of they use as cache.
Crucial is owned by Micron the 3rd largest supplier of NAND flash memory at ~16 percent of the world's supply, Samsung is the biggest supplier at ~30%. Also, Samsung designs, and makes their own SSD controllers instead of using an SSD controller from another company (Phison, Silicon Motion, Marvell etc).
Caze, 26 Jan 2021Shows how much people discussing the A/B solution with two partitions actually knows about it.... moreI guess people with 128GB+ (maybe 64GB+) phones wouldn't need to care about less than 0,5GB less space in change for seamless updates.
Anonymous, 27 Jan 2021That reply shows you don't know much about these things. In one ear and out the other.Why don't you just log on with your usual astroturfer accounts instead of being a neutered anon poster? Apple, the OG QAnon....

The interface is not primarily the reason for price, HDDs also use SATA. It's because of the NAND flash storage we pay more, which also comes with higher performance.
You want SSDs to be cheaper, but at the same time defend Samsung even though they sell their SATA SSDs for like €30 more than Crucial.
Anyway, even PCIe 3.0 SSDs are alot faster and are actually about €30 more expensive. Just a year ago it was €100. Gen 4 is too new to become cheap fast.
AnonD-762416, 26 Jan 2021Explain to me why SATA SSD is nearly as expensive as NVME PCIE 4.0 storage? If it's free,... moreYou got it all wrong. NVME SSDs are becoming as cheap as SATA SSDs now, especially Crucial / Micron ones. Those are whole units for consumers, not individual memory chips for manufacturers who get it for a couple of bucks in bulk. Samsung can afford it easily. Maybe they don't want to use this feature to make sure they can brick old devices in the future, forcing consumers to buy new phones.
Not that i care to much about what samsung does, but WOW... crazy.... you can't use your phone for 10 Minutes tops, what a tragedy...

Shows how much people discussing the A/B solution with two partitions actually knows about it. Based on this article https://source.android.com/devices/tech/ota/ab/ab_faqs the A/B partitioning used a whopping 320MB more space on the Pixel compared to not using it.

Not necessarily. Motorola's shattershield protection has never been able to break the front glass.

No they do... moreI've never cracked my glass so I have to think most of this comes down to poor handling of the phone. If you'll crack your back glass you'll crack your front glass. So IMO plastic over glass on the rear is a moot point.
Lyndino, 26 Jan 2021And then some idiot screws up, bricks his phone and constantly complains about Samsung quality... moreI've unlocked the bootloader on nearly all of my phones since 2010 and I've never bricked one of them. Some companies have delivered updates that result in bootloops. Without an unlocked bootloader there is no way for the end user to fix this theirself.
Hildr, 26 Jan 2021Ups, my bad, it's 100€/ton after treatment for the glass.Is that Gorilla Glass 5 / 6 / Victus?
Anonymous, 26 Jan 2021yes but plastic doesn't breakI prefer glass personally, but if manufacturers want to use plastic. Just reflect that in the price. Ultimately they just switch to plastic because they can. Samsung and Apple literally do whatever they want and people still buy the phones so it doesn't matter what consumers actually want. The rest of the industry follows suit.
Anonymous, 26 Jan 2021Funny enough my LG does support this... Less funny is how slow the updates are being releas... moreI would rather wait one extra minute for the update to install than not get any updates for a year. There's nothing worthwhile about this news other than Samsung having pull in the industry. As if we didn't already know that.
