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.

Then there was your 3 1/2 drives
Maybe because I was 3 years old back then :p
No one compares the speed between HDDs and SSDs. Perhaps only a small fraction of people consider data retrieval methods. This is because the reliability of the drives and how you configure them determines risk. Both RAID 10 and small arrays of RAID 6 provide excellent resiliency and give superb performance as well.
HDDs are simply being outclassed in 2016 and onward.
You can get a 500GB for $170 but still that's a lot less space for more money.
It's getting there though, 2TB SSD's at HDD prices that's going take time.
I am absolutely excited over this news. They just put all other SSD vendors on notice.
I buy a new laptop and I put in a new $55 1TB HDD, if I want SSD I have to pay $330. Do you see the price per GB difference? It is very big and if I buy a laptop for $300 (because only cheap laptops have the lowest price per performance and "what you get") I pay more for the SSD than the laptop itself. This is outrageous!
Or if I buy a desktop PC and I put in two 3TB HDDs in RAID 1 and it would still be only $200 compared to the unknown high price for the SSD configuration.
The price has to come down to the same level as the price of HDDs are now. And HDDs can retain data after 5 years of inactivity, can SSDs also?
Point taken on mass storage but, remember. Producing anything in bulk is cheaper, that's not only limited to HDDs but, point taken nonetheless.
I look forward for cheap drives that can pass the ancient DDR-200 RAMs on speed :))
This tech could trickle down and really make the CPU divisions significant, for example i3 = 4GB, i5 = 8GB, and i7 = 16GB.
But you cannot include only that memory on laptops and miniPCs because it would become non-upgradeable and that would mean I could not have i3 with 16 GBs of memory on laptop. It would be a disaster and it would limit the use of a device.
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.
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.
