Further, it is twice the capacity of the former largest SSD - Samsung's 15.36TB drive, which was released in March 2016. As long as we're talking about big numbers, the drive's 40 GB of DRAM cache is also worthy of attention.
In addition to the doubled capacity, performance levels have risen significantly and are almost twice that of Samsung's previous generation high-capacity SAS SSD. Spinny metal hard drive capacities top out in the mid-teens these days.
The drive also comes with a new controller that integrates nine main and sub controllers used in previous SSDs. TSV, which supports the integration of 8Gb DDR4 chips, helped in including 10 4GB TSV DRAM packages in the drive.
Samsung's new 30.72TB whopper uses a 12Gb/s SAS connection that provides the dual port and failover features prized in the data center. It should be noted that this is the first time that Samsung used TSV-applied DRAM in an SSD.
The drive offers read and write speeds of 2,100MB/s and 1,700 MB/s. This is three times faster than a normal SATA SSD. Sequential reads could hit a claimed 2100 MB/s, and sequential writes could run at up to 1700 MB/s. Instead, Samsung expects it to be a hit among enterprise customers, wanting to pack as much memory - and fast memory, at that - into as small a footprint as possible. "The PM1643 also offers a mean time between failures (MTBF) of two million hours", the press statement reads.
It's not clear when the PM1643 will go on sale, but Samsung said it started manufacturing initial quantities in January 2018 and has plans to expand the range throughout the year with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions.
Samsung executive VP of memory sales Jaesoo Han said that Samsung will "continue to move aggressively in meeting the shifting demand toward SSDs over 10TB".
The device is guaranteed for five years based on one full write per day, great for data centres, but we think it's important to keep reminding ourselves that this is transferrable tech - somewhere down the line, this could be in your computer at home.
