The Samsung 980 Pro, which has already been exhibited at CES 2020 but has not been announced, has appeared on a Samsung Singapore product page. The final specifications of the new NVMe SSD with PCIe 4.0 are therefore now known.
With the Samsung 980 Pro, the South Korean manufacturer is introducing support for PCIe 4.0 in its SSD end customer division for the first time. The Singaporean product page was available for a short time, but apparently Samsung has now consciously deactivated it.
The official datasheet reveals that the NVMe SSD appears as a model with 256 GB, 512 GB, and one terabyte.
Samsung 980 Pro Read Speeds Twice as Fast as Before
The manufacturer specifies the maximum read speed of up to seven gigabytes per second (GB / s) for the 1 TB model, 6.9 GB/s for the 512 GB model, and 6.4 GB/s for the 256 GB model. The maximum write speed is up to 5 GB/s for the two larger variants and up to 2.7 GB/s for the model with the smallest capacity.
MLC-V-NAND with three bits per memory cell is used as flash memory and the SSD uses an SLC cache. Samsung has not yet given any official information on the size of the SLC buffer. The DRAM cache is 512 MB (256 GB / 512 GB) or 1 GB (1 TB) and a Samsung Elpis controller is installed.
As usual, the manufacturer grants a five-year guarantee, provided that the specified writing quantities in TBW are not exceeded beforehand. Depending on the capacity, the product page speaks of 150, 300, or 600 TBW (Total Bytes Written).
Compared to the 970 Pro, the TBW information is halved for the new SSD. But the speed is also much higher. The 1 TB variant of the 970 Pro manages a maximum of 3.5 GB/s reading and 2.7 GB/s writing. No information is yet available on prices and availability.
The market launch of the Samsung 980 Pro is expected to take place shortly.
