Samsung shipping 15TB SSD

Recommended Posts

Samsung Electronics announced Wednesday that it is now shipping the industry's highest-capacity solid-state drive (SSD), the 15.36TB PM1633a.

Samsung revealed it was working on the drive last August, saying it would use the same form factor as for a laptop computer: 2.5-in, but the drive is 15mm in height. Laptop SSDs are typically 9mm, 7mm or 5mm in height (for ultrathin notbooks).

 

The 2.5-in SSD is based on a 12Gbps Serial Attached SCSI (SAS) interface for use in enterprise storage systems. The PM1633a has blazing fast performance, with random read and write speeds of up to 200,000 and 32,000 I/Os per second (IOPS), respectively. It delivers sequential read and write speeds of up to 1200MBps, the company said. A typical SATA SSD can peak at about 550MBps.

Because the PM1633a comes in a 2.5-in. form factor, IT managers can fit twice as many of the drives in a standard 19-in. 2U (3.5-in.) rack, compared to an equivalent 3.5-in. storage drive. The SSD also sets a new bar for sustainability, Samsung said. The 15.36TB PM1633a drive supports one full drive write per day, which means 15.36TB of data can be written every day on a single drive without failure over its five-year warranty.

The SSD can write from two to 10 times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies.

Samsung said it is betting on the PM1633a SSD line-up to "rapidly become" the overwhelming favorite over hard disks for enterprise storage systems.

"To satisfy an increasing market need for ultra-high-capacity SAS SSDs from leading enterprise storage system manufacturers, we are directing our best efforts toward meeting our customers' SSD requests," Jung-bae Lee, senior vice president of Samsung Electronic's Application Engineering Team, said in a statement. The performance of the PM1633a SSD is based on four factors: the 3D NAND (vertical NAND or V-NAND) chips; 16GB of DRAM; Samsung's proprietary controller chip; and the 12Gbps SAS interface.

The random read IOPS performance is about 1,000 times that of SAS-type hard disk drives and the sequential read and write speeds are more than twice the speed of a typical SATA SSD, the company said.

Combining 512 of Samsung's 256Gbit V-NAND memory chips enables the SSD's unprecedented 15.36TB of data storage capacity in a single drive. V-NAND, or 3D NAND, is a way of stacking NAND cells one atop another like a microscopic skyscraper. Not only does it double the density of standard planar NAND chips, from 128Gbits to 256Gbits, it also increases performance.

Samsung originally announced the 48-layer V-NAND last August, saying it also sports 3-bits per cell or multi-level cell (MLC) NAND technology.

I'm also thinking that this could be the final nail in the coffin for mechanical hard drives.  The one think they still had going for them was capacity.  Even the latest HAMR (Heat-assisted Magnetic Recording) drives can't come close...

 

We'll think of terabytes in the future as we do gigabytes today.  I can't wait for the day when a 1TB PCIe SSD is laughable.

I grabbed an old Fujitsu 520T laptop the other day, of course first thing I do is open it up, see what we have right.

The HDD is a Toshiba HDD2517 , which is a 814MB drive

Not to mention I have nothing here that connects to the pins,we've come along way.

Seems to be something missing yes? lol Such as a scsi connector

Too bad my 5.5 yr old iMac will only accept 3 Gbps SSDs, but hey, they're getting cheap. I'm like 3 generations behind now, and still using 800 Mbps external Firewire. LOL. The DIY kit of tools and adapters for installing the SSDs costs almost as much as the SSD now to put one inside the iMac.
