Samsung Starts Volume Production of a 30.72-terabyte SSD
And before you get your hopes up, you'll never be able to afford it :) Samsung announced that it has begun mass producing the industry's largest capacity Serial Attached SCSI (SAS) solid state drive (SSD), the PM1643 - for use in enterprise storage systems. This puppy has 40GB of DRAM also.
Leveraging Samsung's latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips, the 30.72 terabytes (TB) drive delivers twice the capacity and performance of the previous 15.36 TB high-capacity lineup introduced in March 2016. This breakthrough was made possible by combining 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512 Gb V-NAND chips. These super-dense 1 TB packages allow for approximately 5,700 5-gigabyte (GB), full HD movie files to be stored within a mere 2.5-inch storage device.
Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging and associated software. Included in these advancements is a highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD.
Complementing the SSD's hardware ingenuity is enhanced software that supports metadata protection as well as data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm to ensure high reliability and minimal storage maintenance. Furthermore, the SSD provides a robust endurance level of one full drive write per day (DWPD), which translates into writing 30.72TB of data every day over the five-year warranty period without failure. The PM1643 also offers a mean time between failures (MTBF) of two million hours.
Samsung started manufacturing initial quantities of the 30.72 TB SSDs in January and plans to expand the lineup later this year - with 15.36 TB, 7.68 TB, 3.84 TB, 1.92 TB, 960 GB and 800 GB versions - to further drive the growth of all-flash-arrays and accelerate the transition from hard disk drives (HDDs) to SSDs in the enterprise market. The wide range of models and much improved performance will be pivotal in meeting the growing storage needs in a host of market segments, including the government, financial services, healthcare, education, oil & gas, pharmaceutical, social media, business services, retail and communications sectors.

Improvements to tech should at least eventually lead to more TB sized SSD's if nothing else, still likely going to be really expensive but little by little traditional HDD's might start seeing gradual replacement if nothing else comes along in the meantime.
EDIT: One of these would still be sweet to have though. :p
I highly doubt that and even the consumer 4TB are so ridiculously overpriced it ain't funny and 30TB SSD I beat well north of 20k

I suppose it's to be expected, even the 256 GB models are still quite expensive though the speed advantage and other improvements over mechanical makes it a worthwhile upgrade and quite a bottleneck removal on modern systems for a variety of tasks.

(Read and write speed but also less seek times and such.)
That was a interesting read too, good information and I really under-estimated the price range for enterprise hardware and it rises even more as storage size increases.
(Which I did know but not quite to the extend I had thought, it ramps up by a lot more.)
Well nothing bad about having a storage HDD and a system SSD though a full HDD replacement is not happening anytime soon then.
(Besides HDD sizes are also increasing year by year even if they can't match a SSD in terms of speed.)
I suppose HDD's were a bit like this initially too though, 10 - 20 MB of storage for a home computer though back then it was thought to be a lot but it costed a small fortune too.

I had a upgraded 40MB HD in my 386 and it was awesome had so much storage space would never fill that up.
