Samsung's Fastest Phone Memory Ever Goes Into Production at 512GB (cnet.com) 44
Samsung today said it's started mass producing 512GB mobile-focused flash memory with over twice the read speed and 1.5 times the write speed of the previous leader, the 1TB module announced last month at CES. From a report: The V-NAND (PDF) memory is based on its embedded Universal Flash Storage (eUFS) 3.0 spec -- the 1TB is eUFS 2.1. Samsung says the 512GB memory can hit read speeds up to 2,100 megabytes per second compared with 1,000MB/sec of the 1TB flash; sequential write can hit 410MB/sec versus 260MB/sec. The eUFS 3.0 1TB memory is slated to arrive in the second half of 2019.

Because having 512 GIGABYTES of PHONE RAM is really what the consumer needs. Can you make it fold and come in pink? I'll take out a mortgage, must have the new shiny whizbang!

Not so much for iOS, but for Android phones, I find they fill up much faster.
I am not trying to Troll. it is probably because you can do more custom stuff on Android phones, that they get filled up faster. While Apple Walled Garden approach to Apps makes storage much smaller first by reducing what you can possible use, and often rejecting apps that use a lot of resources (even it for a purpose) and also forcing apps to follow UI Policies, so there is more shared resources.

Android is based off of Linux, while not Unix, was designed with many of the Unix principals in mind.

Sorry, blame JEDEC for that - UFS is the next-generation flash interface, which is what is done at the physical connect

Yeah, UFS was a decent idea back in the '80s, but filesystems have advanced a lot since then. Find an OS with UFS support and try it out. You'll find it's slow and handles power failures poorly.

Oh sure, UFS is better than FAT, but that's not hard to do. Just about anything's better than FAT in terms of performance and functionality. The one advantage FAT has is that it's dead simple and easy to implement. A high school student could probably implement FAT.
The BSDs kind of cheat by doing write-ahead logging for entire partitions. It's not that the filesystem supports it, it's that the OS storage layer wraps it around the filesystem. Unlike the journaling in newer incarnations of ext and HFS it

It's not Samsung, it's good old JEDEC. The official JEDEC name for this storage interface is Universal Flash Storage, abbreviated to UFS. Initialisms are always going to be overloaded unless they're made excessively long and convoluted (hello PCMCIA). I mean, take SMBC: it's Sumitomo Mitsui Banking Corporation, Sydney Missionary and Bible College, and (webcomic) Saturday Morning Breakfast Cereal.

Quick off the top of your head what is the Bus transfer rate of your motherboard?
The thing is, sometime technology reaches a good enough state, that for normal use, knowing how much you have isn't a big deal anymore.
Mobile devices are not well designed for heavy multi-tasking like your desktop is. And with rather fast storage of state when you switch apps, Having dozens of Gigs of Volatile Ram isn't as needed on such a device.

How do they handle the heat? Many nvnm desktop solid state storage have heat sinks and they are bigger too.
As for memory versus storage this used to be a continuum . Old computers leaned heavily on virtual memory page swaps. And newer ones have a continuum of speeds for memory caches and dram and memory backing the ssd and then ssd fused with spinning disk.
On cellphones Apple initially only let one app be active at a time in memory .
And future designs show even more memory types . Many core machines have

Because it is still Memory, and it is still RAM (Random Access Memory). The difference is that this product is Non-Volatile RAM that data will not go away after its power is turned off and what you call Memory is Volatile RAM, which will go away after power is lost.
However both is Memory and RAM. As it hold data given to it for later retrieval. And they are Random Access meaning you don't need to sift threw a blocks of data you don't need until you happen to get to your useful memory spot.

Nope, Flash can't be accessed randomly, only by a block of the whole page. And even worse, those blocks need then to be erased in large groups. Actual memory not only is byte addressable, but also has around 4 orders of magnitude better access time than the flash disks in the article. As for non-volatile memory, it's 2-3 orders of magnitude faster than this fancy flash.
Per your definition, a spinning disk would also count as memory, as you don't need to read it sequentially but can seek to a given sector

So yeah, Samsung is producing a 512GB memory chip.

Re: (Score:2)
Chances are you SSD's arn't really that big, A good portion of it is protective casing, and connectors spreading out so they can be clipped in, and even spacing for anything that will need a human to be able to solder together. The big point about RAID, is if one fails, you can replace the failed component with a new one. Having an embedded RAID device the size of a stick of Gum would be counter productive.
