Western Digital is not sitting in its wheelchairs and has unveiled the veil of its latest enterprise-class SSD SAS, Ultrastar DC SS540, which promises 2.5 million hours of MTBF life. With a SAS 12 Gb / s interface, it has 2.5-inch, 15-millimeter disk space for potential customers, with options from 800 GB to 15.36 TB. 96-cell TLC, 3D NAND flash memory rests underneath the casing and, depending on the model, the sequential read speed is from 1935 to 2130, and the sequential write speed from 1024 to 2109 MB / s. Random read / write operations take about 237 000 and 470,000 IOPS operations.


The 800 GB, 1.6, 3.2 and 6.4 TB versions are authenticated for 3 caps per day (DWPD = 3), while the 960 GB, 1.92, 3.84, 7, Variants 68 and 15.36 TB are forced to mature with a "churic load" ( DWPD = 1) daily. Of course, because it fits into this category, the devices have many protective mechanisms designed to prevent data loss in the event of a failure, are compliant with the T10 Data Integrity Field (DIF) standard, and also have features such as secure fast cleaning or saying TCG + FIPS encryption . For simplicity, additional specifications have been added in the form of one image.


We will also add that although the control group has already begun testing the samples, actual market launch is expected in the first quarter of next year.
