Samsung has introduced its new lineup of datacenter-class SSDs that uses its latest V-NAND flash memory and a SATA interface. The new drives offer up to 7680 GB capacity, consume less power than predecessors including helium-filled hard drives.
The Samsung PM833 SSDs are based on the company’s proprietary controller as well as 64-layer TLC V-NAND memory. The new drives carry 4 TB and 8 TB of raw NAND flash memory to provide 3840 and 7680 GB capacities. Meanwhile, the key feature of the PM833 is not capacity, but very low power consumption when compared to other SSDs: they consume only 2.8 W during read operations and 3.7 W during write operations. To reduce power consumption, the PM833 use several methods: in addition to usage of high-density V-NAND flash memory, they use LPDDR4 DRAM produced using a 10-nm-class process technology. Furthermore, the drives support Power Disable (PWDIS) feature of the SATA 3.3 protocol that enables power management in individual SSDs within a data center. Obviously, to take advantage of the PWDIS, host systems have to support this feature too.
When it comes to performance, the Samsung PM833 can read data sequentially at 550 MB/s and write data at 520 MB/s. As for random performance, the new drives are capable of 98,000 read IOPS as well as 28,000 write IOPS. Meanwhile, the endurance of Samsung’s PM833 SSDs is rated at 5466 TB for the 3840 GB model and 10,932 TB for the 7680 GB SKU.

Samsung did not disclose MSRPs of the PM833 drives, but since the SSDs are designed primarily for cloud datacenters, their actual pricing will depend on negotiations with particular clients.
