Samsung Shows Off its Biggest and Fastest SSDs at FMS 2015

At the 2015 Flash Memory Summit, Samsung announced the fruition of its swanky new 48-layer 3D V-NAND chips, the PM1633a. Built in the 2.5-inch form-factor, and featuring a SAS 12 Gb/s interface, this drive offers an unformatted capacity nearing 16 TB (15,360 GB to be precise). The drive relies on ten 48-layer stacks of 256 Gb 3-bit NAND flash dies, making up 15,360 GB of unformatted capacity. Samsung showed off a system with 48 of these drives, making up 720 TB of total storage.

Besides the largest SSD, Samsung also showed off the fastest. The PM1725 SSD, designed for servers with high-traffic databases, where throughput is the king, is built in the 2.5-inch form factor (up to 3.2 TB) and HHHL form-factor (up to 6.4 TB). It features a PCI-Express 3.0 host bus, and talks to the OS over the modern NVMe protocol. The two offer random access throughput of up to 1,000,000 IOPS.

Pill MonsterYou don't seem to understand how cache works, or what caching is. RAM IS cache. It's cache for the HDD. Don't you get it?
Caching is simply a matter of preloading data so it can be accessed faster.



If you believe the only type of cache is on the CPU, it isn't.
I said this yesterday why database servers have so much RAM, the files are cached from the HDD into RAM. That is caching. Man talking to you is like talking to a wall.


Problem with your logic is that I was talking about actual cache memory and was specific in my wording.
AquinusThat's why I tried to be careful of my statement. I completely agree which is why I said it should almost be treated as a level of cache. In reality a small enough application will end up completely residing in L2 cache. I would see something like this working no differently by simply using another level of memory should it be available. It's just something that's between you're run of the mill SRAM cache and system memory so you kind of want a little bit of both in terms of functionality to be present at that level, if that makes any sense.

If you consider memory in general, it tends to be virtualized and pages handled by the either the OS and hardware depending on the level. From a logical level, I would want it to be in the same domain as RAM but in the case of using more than what's on the CPU I would want it to act like a cache if there is external memory. I guess that's what I mean by kind of like system memory but kind of like cache.
I think I was 100% clear that I was talking about cache stores not caching algorithms. This is just a continuation of the last thread that was closed. I highly suggest your drop the matter because before you know it a mod might be intervening for going off topic and continuing a discussion that they stopped.

I can drop a matter, how about you learn to do the same and get over it.

There is no problem with my logic, the problem is you can't admit I'm right.

I said at the very beginning RAM is used for HDD caching, you nagged at me to prove it to you.

The cached HDD files are physically in RAM. Even in a virtual environment, if the PF is off or pages are locked in RAM there are no pages on the drive.
They are in RAM. That is CACHE MEMORY. Not caching algorithms. It actual cache. Anyone who would argue against that is just splitting hairs.

You may have a C.S degree, really great for developers, but I have MS cert which is very relevant in my field. Man nobody can know everything, not me and not you.

So, with that out of the way, for me the topic is dropped and yes we can put it behind us..... I haven't checked your pm yet, I will soon.


Maybe a mod can close this or something?

Maybe you guys could stay on topic and not bicker with each other constantly. I know I'm getting tired of it.

FxYes, it will still take some time, but I am excited primarily about HDDs finally being overcome in capacity. This is a BIG hurdle finally cleared. Now it is just a matter of time, and I think that time will drive the prices down faster than we can estimate. There are other entities coming out with 8 and 10TB SSDs so its game on between all of them to be competitive, thus bringing down prices. Samsung, with its V-NAND, is leaps and bounds ahead of everybody and they have an excellent history of offering value in SSDs in both price and performance.

I am absolutely excited over this news. They just put all other SSD vendors on notice.
It's not just capacity they have to compete with, at this time backing up the same amount of data on a SSD cost a a load more to company's and then there is backup data which if stored on a SSD costs a lot more too.

And if the data is really important recovery options sky rocket when the data is on a SSD.

Then there was your 3 1/2 drives

If only they loaded like that when we were loading our games with them lol, at least some people have actually found a use for them ha.

So, where is my 2TB SSD that can be bought for a price of a single testicle? Surely I don't need both of em XD

I wish I had that much harddrive space. so far I have not even filled half of my 2 tb on my envy yet.

My computer is a i5 cpu and has 12gb ram in the system and a 2TB harddrive.
