Samsung massive 32TB SSD includes cutting edge 3D chip technology

The size of SSDs are ramping up at a dizzying pace – Samsung is intensifying race with its highest capacity 32TB SSD.

32TB SSD doesn’t match capacity of Seagate’s recently announced 60TB drive, but it is denser. drives are being shown at the Flash Memory Summit in Santa Clara, California, this week.

Samsung’s SSD can fit in smaller 2.5-inch slots while Seagate’s 60TB drive fits in 3.5-inch slots

SSD makers are packing more terabytes in drives because of storage demanded by applications like virtual reality, high-definition video, machine learning, and analytics.

Samsung wants to put 100TB of storage into SSDs by 2020, company’s drives are faster -more durable than competitors’ because of its advantage in manufacturing

said Ryan Smith, senior SSD and storage product manager at Samsung.

The 32TB SSD is the first one based on Samsung’s fourth generation V-NAND flash memory, which stacks 64 NAND storage layers in one chip package. That’s the highest density available in chips.

The technology delivers higher sequential read-and-write performance than its predecessor, the 48-layer third generation V-NAND flash memory, Smith said.

Stacking storage layers is a way to add SSD capacity as devices get smaller and more power-efficient. The layers are linked through a proprietary interconnect.

Samsung’s 32TB SSD is faster and more reliable than its 15.36TB drive, Smith said. The company will share performance details at a later date.

The SAS (serial-attached SCSI) SSD is targeted toward servers, flash arrays, and external storage systems, Smith said. The drive isn’t compatible with NVMe slots.

Samsung also announced new Z-SSD, which is NAND flash designed to be used as cache or temporary storage in data centers.

The Z-SSD will provide four times lower latency and 1.6 times faster sequential read speed than the Samsung PM963 NVMe SSD, which is a high-end enterprise SSD.

Samsung is also working with other companies to create a new storage form factor
