Samsungs monstrous 15TB SSD is now shipping

Submitted by: Odio @ 07:37 AM | Tuesday, March 29, 2016 | (url: http://arstechnic...)

Samsung has announced that it is now shipping its PM1633a SSD. That's a boringly mundane name for a drive that's anything but: the PM1633a isn't just the biggest SSD around, it's straight-up the biggest drive around. At 15.36TB, it dwarfs other SSDs and surpasses the capacity even of the very latest magnetic spinning disks. Remarkably, it packs all this storage into a conventional 2.5-inch package.

The company explained how this was done in August last year. While traditional integrated circuits (whether processors or flash memory or RAM or anything else) have a flat, essentially 2D structure, this drive uses Samsung's 3D V-NAND technology, which vertically stacks 48 layers of NAND cells to greatly increase the storage density. The highest performance flash memory stores a single bit in each flash cell; Samsung's trades a bit of performance for density, storing three bits per cell. Each die using this technology stores 256Gb (32GB) of data.

The company then adds a second level of layering: 16 of the 256Gb dies themselves are stacked up, creating a package with a 512GB capacity. Of these packages, 32 are used in the PM1633a to give it its total 15.36TB capacity. Samsung plans future versions with 7.68TB, 3.84TB, 1.92TB, 960GB, and 480GB capacities. The 15.36TB unit also has 16GB of RAM embedded.

The PM1633a is aimed at enterprise markets, and accordingly it will use an enterprise interface: 12Gb/s Serial Attached SCSI (SAS). The raw performance of this drive won't match the very fastest PCIe-attached drives, with Samsung saying it offers read and write speeds of 1,200MB/s, with 200,000 read and 32,000 write operations per second. However, these numbers handily beat spinning disks, and previously, that was the only way of offering this kind of capacity. As for endurance, Samsung says that the drive supports 15.36TB of writes per day over its five-year life cycle.

The South Korean firm is leaving one important detail out, at least for now: the price.

Intels new X25-M 80GB SSD is one of the fastest consumer solid state drives available - a technology that's commonly cited as being the future of storage technology. But at $600, this puppy isn't cheap. Is the technology actually worth it yet?

Toshiba to Release 512GB SSD in '09

Submitted by: KnightMare @ 11:02 AM | Friday, December 19, 2008 | (url: http://www.comput...)

Toshiba said today that it will soon offer samples of 512GB solid-state drives (SSDs), which could make their way to laptops and other devices by mid-2009.

Storage capacities of SSDs are doubling every few months, but Toshiba's 512GB version is the highest storage capacity announced for SSDs intended for consumer devices like laptops. Most PC makers today offer 128GB SSDs for laptops, and competitor Samsung recently said it put into mass production 256GB SSDs, which will become available in a few months.

Samsung announces World's Fastest SSD

Submitted by: KnightMare @ 09:17 AM | Monday, May 26, 2008 | (url:

Samsung Electronics announced today the world's fastest, 2.5", 256GB multi-level cell (MLC) based solid state drive (SSD) using a SATA II interface.

The new Samsung 256GB SSD is also the thinnest drive with the largest capacity to be offered with a SATA II interface.
Performance data of the new Samsung 256GB SSD features a sequential read speed of 200 megabytes per second (MB/s) and sequential write speed of 160MB/s.
The Samsung MLC-based 2.5-inch 256GB SSD is about 2.4 times faster than a typical HDD. Furthermore, the new 256 GB SSD is only 9.5 millimeters (mm) thick, and measures 100.3x69.85 mm.

Perhaps Benchmark Reviews like to ride the edge of technology just a little too close, since we've tested more DDR3 and SSD's than almost everyone else on the web, but the bleeding edge is what where most enthusiasts like to live. OCZ allowed us to test their first Solid State Drive product, the OCZSSD64GB, and while the pricing very affordable the performance wasn't so impressive. Now just a short three months later, OCZ has returned with one of the industries very first SATA-II SSD products, the OCZSSD2. It would be a shame to give away the details, but it appears that the extra time at the design table was very well spent. OCZ's new Solid State Drive offers industry leading performance matched by ultra-affordable pricing, and sets a new record.

Seagate sues SSD maker STEC

Submitted by: KnightMare @ 02:24 PM | Tuesday, April 15, 2008 | (url: http://www.nytime...)

Seagate Technology, the largest maker of computer hard drives, made a pre-emptive strike against an emerging competitor on Monday when it filed a lawsuit in federal court accusing STEC Inc. of patent infringement.

In the suit, Seagate contends that STECs solid-state drive products violate four Seagate patents covering how such drives interface with computers.

STEC, based in Santa Ana, Calif., makes solid-state drives for corporations and other large enterprises, a market that Seagate executives have said the company plans to enter this year. The suit was filed in Federal District Court in the Northern District of California.

OCZ announces 32 & 64 GB SATA II Solid State Drives

Submitted by: KnightMare @ 08:25 AM | Thursday, March 13, 2008 | (url: http://www.ocztec...)

32 and 64GB capacities aren't all that impressive when it comes to SATA II 2.5-inch solid state drives, but OCZ's new devices do claim 120MBps read and 100MBps write speeds which would put it up there on the ranks. Unfortunately, OCZ neglected to clue anyone in on price or release date for these puppies.
