Samsung unveils world's largest SSD with whopping 30TB of storage

Samsung unveils world's largest SSD with whopping 30TB of storage

Now this year, Samsung is taking it a step further with the new "PM1643", a 30TB SSD built on the latest 512Gb V-NAND. The record-breaking drive is the industry's largest SAS SSD; indeed, even its 40 GB of DRAM alone is more flash than some smartphones and tablets are shipping with in storage today. The drive offers 12GBps SAS interface with read and write speeds up to 400,000 IOPS (Input/Output Operations per Second) and sequential read and write speed of 2100MBps and 1700MBps respectively.

Samsung has unveiled the world's largest solid state drive - an unassuming-looking bit of kit that boasts a whopping 30.72 terabytes of storage. As an example, the company points out that 5,700 5GB full HD movie files can be stored on a single 2.5-inch drive using these chips. Sequential read and write speeds of up to 2100 MBPS and 1700 MBPS respectively were recorded in tests done by Samsung.

According to Samsung, the new drive performs approximately four times better than a typical SATA SSD; as these drives are focussed on the enterprise, the company also noted that they offer a mean time between failures (MTBF) of two million hours.




Production of the 30.72 TB SSD kicked off last month, though Samsung plans to add to the family later in 2018. Jaesoo Han, executive vice president of Samsung's Memory Sales and Marketing Team commented that, "Samsung will continue to move aggressively in meeting the shifting demand toward SSDs over 10TB", which is good news for everyone.

The new SSD also gets a new control architecture that combines nine controllers from the previous high-capacity SSD range in a single package. This is notably the first time when an SSD has included a TSV-applied DRAM. It features Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages totaling 40GB of DRAM.

Coming to the software front, the PM1643 supports metadata protection. Samsung also said in its press release that the drive is created to endure heavy workloads and can survive one full drive write per day (DWPD), which is equivalents writing 30.72TB data into the drive daily for the 5-year warranty period, which seems to be quite a bold claim.
