Class Notes

  • SSD’s are built with NAND Flash Memory which is non volatile memory.
  • There are numerous types of interface for Solid State Drive with PCIe being the fastest.
  • TRIM is kind of like defragmenting for a SSD.  Windows 7 and 8 do it automatically.  XP and Vista require you use a manufacturer piece of software.
  • “Memory Wear” means the NAND will degrade over time.  Although this is technically a concern unless you are running a server for the likes of Facebook your PC/ Server will be replaced before the drive fails.
  • IOPS means Input / Output Operations per Second and measures the total number of individual transactions per second the drive can handle.  This is important in database operations.
  • “Sequential Read/ Write Speed” means the speed the drive can read or write contiguous files.
  • “Random Read /Write Speed” means how fast the drive can read/ write to numerous different files



Lab Setup Used in Demonstration

  • The ETCG Host Computer Specs are:
    • ASUS Model: CM6870US01
    • 16 GB of RAM
    • 1 TB 7200 RPM Hard Drive
    • i7 3.4 GHz Intel Processor
