Samsung recently started selling 4TB 850 EVO SSDs regardless of capacity or on the yuan prices have been amazing enough, but only in the consumer field only. Do anything within the enterprise, and more wild monsters everywhere. In March this year, Samsung announced a new enterprise-class SSD PM1633a, capacity up to an amazing 15.36TB, now it has appeared in the market, CDW, SHI two US retailers are asking $ 10,311.99 and $ 9690, or about RMB 68,000 yuan, 64,000 yuan.
Meanwhile, Samsung also increased for more small-capacity version of the series, including: 480GB, 960GB, 1.92TB, 3.94TB, 7.68TB, the last of which sell for $ 5729.99, 38,000 yuan.
PM1633a SSD based on Samsung customize the third-generation 3D V-NAND 48 layer three-dimensional stacked flash, TLC particles, single grain capacity 256Gb (32GB), 16 Ke packaged together to form a 512GB capacity, a chip, and the chip 32 composition 15.36TB capacity reservations about 1TB as a redundant space, in addition to 32GB DDR3 as a cache.
Due to restrictions, large capacity SSD performance of a variety of factors are often less than ideal, for which Samsung has developed a new autonomous controller, with special custom firmware, SAS 12Gbp high-speed interface (2.5 inch / 15 mm), will continue to read and write speed increased to 1200MB / s, 900MB / s, random read and write is up to 195000 IOPS, 31000 IOPS.
Reliability, MTBF 2 million hours, with tantalum capacitor to prevent power-down losses and support the overall write once a day, five-year warranty.
Unit price of about 65,000 yuan looks incredible, but for large-capacity storage needs of data centers, in fact, a good deal.
For example, Supermicro 2U can be squeezed 48 SAS3 / 12G hard disk, use this 15.36TB SSD Samsung's total capacity will reach 737.28TB, a 42U rack can have 15482TB.
But if you use the traditional 3.5-inch mechanical hard drive, this can only be placed in the cabinet 360, a single block 10TB words but also 3600TB, performance naturally quite different.
