  1. SSD Multiprocessing / Multithreading Chak Yee

  2. How are SSDs involved? • File I/O slowest when seeking and writing to hard drive. • SSDs don’t have platters or mechanical heads, thus eliminates seek time.

  3. Single vs. Multithreaded Read MB/s SSD HDD 384.46 MB/s 80.07 MB/s

  4. Cause of Disparity • Multiple read/write requests to HDDs require head to access different parts of the platter. • SSDs can read/write from multiple modules at the same time. (Varies between makers)
