Nimbus Data is known in the enterprise segment as a manufacturer of ultra high capacity SSDs. Two years ago she ExaDrive DC series SSDs up to 100TB. By the time of launch, she did not name their cost. It has recently become clear why.
Resource TechRadar found that Nimbus Data is finally the cost of their Ultra High Capacity ExaDrive DC SSDs. The 50TB SSD model (EDDCT020/EDDCS050) is priced at $12. A 500 TB model (EDDCT100/EDDCS100) will cost the buyer $100. Calculations suggest that the cost of 40 TB for the first option is $000, while for the second it reaches $1.
ExaDrive DC drives are presented in a 3,5-inch form factor and are available in either SATA III or SAS-2, which is mainly used in server systems. The price remains the same in both cases.
According to the manufacturer, each ExaDrive DC series drive uses four flash memory controllers, which are controlled by a protocol processor responsible for directing data flows. The drives are based on NAND flash memory chips based on 3D MLC technology (Multi-Level Cell, two bits per cell). In addition, each SSD has RAM on board, but Nimbus Data does not specify how much.
Obviously, the main feature of this series of media is their storage density. At the same time, their performance remains at the usual level that you would expect from a simple SATA SSD drive.
The maximum read and write speed of ExaDrive DC SATA drives declared by the manufacturer is up to 500 MB/s. At the same time, performance indicators at the level of random reading and writing can reach 114 and 106 thousand IOPS, respectively. The read and write speeds of the SAS versions reach 450 and 260 MB/s, respectively. And the speed of arbitrary reading and writing reaches 97 and 91 thousand IOPS, respectively.
Nimbus Data also points to a supposedly unlimited number of drive write cycles and gives them a five-year warranty.
