The Korean company has announced a new SSD for the enterprise market, the most ” large world ” according to the statement released to the press.

Samsung is one of the giants of the most prestigious in the field of storage and of the greatest innovators in the category, both the consumer and enterprise side. The company today announced a new SSD model designed just for this last category, the SSD with the largest capacity in the world. With Samsung PM1633a Koreans touch tip 15.36 TB within a 2.5-inch form factor, values which place the new model in the Olympus of solid-state drives.

With the company which had shown inside a rack chassis to two units, which integrated well 48 identical models, for a total of 768 TB available to the client, all through SSD. Samsung has reached a record low of 15.36 TB cramming into a single unit well, 512 V-NAND memory chips 256 GB, stacked in 16 layers to form a single package 512 GB. Combining 32 of these packages you get to 15.36 TB threshold.

Samsung has used the V-NAND third-generation technology that allows you to use individual modules from 48 to 256 GB layer significantly increasing performance, storage capacity and reliability of new solutions compared to its predecessor (PM1633), which used modules V-NAND 128 gigabit and 32 layers. The performances of Samsung PM1633a are absolutely interesting: up to 200,000 IOPS and 32,000 IOPS random read and write, 1200 MB/s read and sequential write.

In comparison, Samsung claims that the random read and write IOPS are ” about 1000 times higher than those allowed by hard-disk SAS “, while about twice as much as those of traditional SATA SSD.

Samsung PM1633a uses SAS interface from 12 Gb/s to a combined total of 16GB DRAM memory, in addition to a firmware specially developed that is able to handle large quantities of files simultaneously.

As regards the reliability, the new model has a duration in time from 2 to 10 times compared to a traditional SSD based on flash technologies MLC NAND planar or TLC. It supports, according to figures released by the company, up to 1 DWPD (drive writes per day), which means that every day can be written over 15 TB of data without encountering problems of various kinds.

Samsung PM1633a initially was sold in version from 15.36 TB, but will follow shortly other solutions that reach up to a minimum of 480GB. Among the intermediate models we’ll find from 7.68 TB, 3.84 TB, 1.92TB and 960GB. Probably exorbitant prices, not yet publicly announced, since we are dealing with solutions designed exclusively for the enterprise market, and certainly not for domestic use or typical common user.
