Farewell, spinning rust
It's even smaller than the 10TB 3.5-inch version

Samsung's 2-5-inch 15.36TB SSD is now shipping, with half as much capacity again as the 10TB 3.5-inch disk drive capacity alternative, and taking up less physical space.
This relative monster of an SSD first appeared at the Flash Memory Summit in August 2015.
The PM1633a drive houses 512 x 256Gb 48-layer V-NAND chips stacked in 16 layers to create a 512GB package. Thirty two of these packages are then used inside the 15.36TB drive. So the individual chips are 3D in nature, and then the 512GB packages with their 16 layers are 3D too.

Later this year Samsung will ship 480GB, 960GB, 1.92TB, 3.84TB, and 7.68TB versions of the drive. It expects this drive "to rapidly become the overwhelming favourite over hard disks for enterprise storage systems," not differentiating between performance and capacity data storage in its statement.

In general, Samsung could be a year or more ahead of its competitors at this 15.36TB capacity level. A flash array using 24 x PM1633 drives would have a capacity of 96TB vs 368TB using PM1633a drives. And that could be done in a 2U or 3U rack shelf space.

my comment: I think Mellor is exaggerating a little about Samsung being "a year or more ahead" of everyone else, based on my reading, but still--there are times when I want to say about Samsung what Robert Redford said about the bounty hunters chasing him and Redford in "Butch Cassidy", "Who are those guys, anyway?" They have been firing on all cylinders in NAND and DRAM for several years now without a misstep. I can't say the same about all of their other businesses, but sometimes I feel like saying to their memory group, "Hey guys, slow down, you move too fast, you got to make the morning last..." Tough competition. Very, very tough. |
