Samsung first unveiled the PM1633a 15.36TB SSD back at the 2015 Flash Memory Summit in August. Today it has started shipping the device, claiming it to be the world’s largest capacity (15.36TB) SSD for Enterprise Storage Systems.

The Samsung PM1633a uses a 12Gb/s Serial Attached SCSI (SAS) interface and comes in a 2.5-inch form factor. Its compact dimensions facilitate the deployment of twice the number of drives in a standard 19-inch 2U rack, compared to 3.5-inch drives, says Samsung.

Jung-bae Lee, SVP of the Memory Product Planning and Application Engineering Team, Samsung Electronics, said that the PM1633a ultra-high capacity SAS SSD was created to satisfy the demand from enterprise storage system makers. Furthermore Lee vowed that Samsung would stay ahead of the pack with faster and more capacious SSDs using its advanced 3D V-NAND memory technology.

As you would expect this SSD drive is no slouch. Samsung quotes the following performance figures for the PM1633a:

  • Read: 200,000 IOPS
  • Write: 32,000 IOPS
  • Sequential read/write: 1,200MB/s

The performance of the drive stems from its V-NAND flash technology, its proprietary controller, and firmware technology, says Samsung. The 12Gb/s SAS interface performance is aided by a total of 16GB of DRAM cache.

With an enterprise product, reliability and durability are also key watchwords and Samsung hasn't neglected these according to the specs and figures quoted. The 15.36TB PM1633a drive supports 1 DWPD (drive writes per day), which means 15.36TB of data can be written every day on this single drive without failure, says Samsung. It claims that the PM1633a "can write from two to ten times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies". Another aspect of the drive designed with dependability in mind is its "highly dependable metadata protection mechanism" in addition to supplied data protection and restoration software tools.

As mentioned in the intro Samsung is now shipping the PM1633a. The headlining 15.36TB density model out now will be accompanied by 7.68TB, 3.84TB, 1.92TB, 960-gigabyte (GB) and 480GB models later this year.

Don't suppose Samsung would be willing to offer you a few of these for a potential competition? :P

Seriously though, if only I had the superfluous cash, I'd love to replace my 4x 3TB drives (2 in PC, 2 in D-Link NAS) with either of the larger two of those drives.

@Mark Tyson: just to confirm, is that 15.36TB (decimal) or TiB (binary)? Doesn't make much difference, just curious. I'm presuming it's probably decimal, as with all other drives I've ever seen.
Would just be able to fit my Star Citizen install on that :)
COSTS as much as a series of Titan Z's in Quad SLI setup with a questionable life span.
I've been waiting for higher capacity SSD's to become available and affordable but the recent Google SSD data seems to suggest that age rather than usage of SSD's is the biggest factor in failure. That's not good news for long term backup requirements.

Yeah it also costs as much as a new small family car and that's just as relevant as its price comparison to Titan Z's. Unless of course you spend all day, every day thinking about Titan Z's.
