What’s In My SSD? SLC, MLC, or TLC?

SLC, MLC, or TLC?Someone recently asked The SSD Guy if there is a way to determine whether an SSD is SLC, MLC, eMLC or TLC.

I found it a little odd to be asked this, since most vendors tell what kind of flash they use in an SSD’s specifications, especially if it’s SLC.

Not finding it there then the next thing I would look at is the price.  Raw SLC NAND flash now sells for about 6-10 times as much as its MLC counterpart, so an SSD with a price of around $1/GB is likely to be MLC and one that sells for around $10/GB is probably SLC.

TLC SSDs are really rare.  There is the Continue reading

Comparing Samsung’s Planar and V-NAND SSDs

Samsung 3D V-NAND Press PhotoSamsung recently introduced  its 3D V-NAND-based 850 SSD which, according to The Tech Report, uses the same MEX controller as the company’s 3-bit planar SSD, the 840, introduced last year.

Samsung said in its keynote speech at the 2013 Flash Memory Summit that V-NAND consumes an average of 27% less power and runs at least 20% faster than its planar counterpart in an SSD application, all while providing ten times the endurance.  It’s only natural to assume that this would allow designers to produce a V-NAND SSD that would significantly outperform its planar NAND counterpart.

SanDisk: We’ll Upgrade Your PCs For You!

SanDisk Tech Assisted Refresh (STAR)In a move that The SSD Guy wishes he had thought of for himself, SanDisk has begun to help corporations upgrade their fleets of notebook PCs by replacing their HDDs with SSDs.

SanDisk calls this program STAR for: “SanDisk Tech-Assisted Refresh”.  According to the press release: “Through the STAR program, SanDisk relieves IT departments of having to manage all aspects of upgrading corporate laptops such as, endpoint inventory analysis, employee service scheduling, system upgrades, data migration, daily progress reporting, post-upgrade analysis and support.”

SanDisk points out that PCs slow down with disk utilization and software updates, lowering users’ productivity.  Often faster storage can solve that problem.

This is not an altogether new Continue reading
