Samsung has announced that it has started mass production of its latest low-powered PCIe SSD – SM951, meant for use in ultra-slim notebooks and workstations. The new SSD isn’t just incredibly energy efficient, but is also one of the fastest SSDs yet as far as read and write speeds go.
The SM951 SSD is mainly targeted at ultra-slim notebook PCs as it is the first SSD in the world to adopt the L1.2 low power standby mode that allows all high-speed circuits to be turned off when your PC is sleeping or when in hibernate mode. Thanks to the L1.2 power standby mode, the SM951 consumes as little as 2mW of power, down by 97 percent from 50mW consumed when in L1 state. It also brings a 50 per cent improvement over the previous XP941 SSD from Samsung when it comes to performance per watt.
The new SSD comes in three capacities – 128GB, 256GB and 512GB. Thanks to an all-new 10-nm MLC Flash production platform, the SSD boasts of sequential read and write speeds of 2,150MB/s and 1,550MB/s respectively with the PCIe 3.0 interface. This is around four times higher than what is achieved by most SATA SSDs currently available. When used with the PCIe 2.0 interface, the drive is capable of read and write speeds of 1,600MB/s and 1,350MB/s respectively. Its random read and write speeds are equally impressive. Samsung claims a random read speed up to 130,000 IOPS (inputs/outputs per second), while the random write speed is claimed to be 85,000 IOPS.
Apart from its extremely high speeds and low energy requirement, the new drive is also incredibly small. At 80mm x 22mm, the SM951 is around one seventh the size of a traditional 2.5 inch SSD drive. At just 6 grams, it is incredibly light weight as well.
As of now, the SM951 will only be sold to manufacturers, but we may see it become available for the consumer market later on like its predecessor.
