Not All SSDs Are Created Equal: Optimizing Performance Through Flash Management

By Doug Rollins - 2013-07-09

To get the most out of solid state storage, you must be privy to a little secret: not all solid state drives (SSDs) are created equal. Optimal SSD performance and reliability rely heavily on all of the drive’s parts—the controller, the firmware, and the NAND Flash itself—working and playing nicely together. Well-thought-out and strategic Flash management helps this kindergarten lesson become a storage reality. 

As George Crump, lead analyst for Storage Switzerland, discusses in detail in his article, Improving SSD Performance Through Better Flash Management, careful attention to several factors contributes to better NAND Flash management—amping up performance and turning down the latency of SSDs:

  • Background operations integration − Keeping these operations out of the way of host I/O requests
  • Efficient garbage collection − Timing is everything
  • DRAM data protection − Making sure what is read back is really what was written
  • Transparent, dynaNot All SSDs Are Created Equal 2mic tuning − Helping you get the most out of your SSD dollar, transparently

Micron’s SSDs already have features built in to address these needs. For example, our enterprise SSDs have the XPERT feature set that improves both performance and reliability. Because we build the NAND, design the drives, and write the firmware—“owning” the SSD from inception on—we know how to best manage Flash and optimize drives.

We devote significant research, time, and engineering energy to produce top-of-the-line SSDs so that our customers can forget about storage and move on to more important things—like running their businesses.

Micron’s unique NAND expertise puts our SSDs and your application’s performance in a category above the rest.
