SSD Based on 3D Nand

Recommended Posts

Can SSD's using 3D Nand be used for Aerospace and defense applications? What is operating temperature for these chips?

That would be up to the aerospace and defense application vendor designing the spec. I think you'd want to ask them, not the SSD maker...:P

Under what circumstances? Things like data retention are extremely temperature dependent. Hence why the NAND spec itself is not that important, the environment and application it's going to be used in is hugely important.

http://www.samsung.com/us/business/oem-solutions/pdfs/V-NAND_technology_WP.pdf

Shows a massive difference in the duration spec'ed for data retention-- the high temperature test is 13 hours at 85C, the low temperature test is 500 hours at 25C (note that that's just the testing, not the actual spec'ed retention of the NAND).

" The JEDEC specification for data retention tells us that for enterprise storage devices, data retention at the end of the service life shall be at least three months (stored at 40°C).  For SSDs in the client computing market, data retention shall be at least one year after the drive’s service life (assuming it’s stored at 30°C).  "

Shows 0C to +70C.

There are several vendors who make Mil Spec SSDs. What they're using I don't know, but it's more of an issue about the need of the application and selecting the right drive, not the other way around.
