What Matters In SSD Market?
Performance has been highlighted

Which Metric Matters Most?
Lots of Performance Comparison with HDD
But no comparison between SSDs
Which Metric Matters Most?
Small Size Performance Matters Fast 4KB Performance is Better
Does Performance Scale Go Linearly with What Users Feel?• Source: Sandisk_20100817_F1B_Tailoring SSD Architectures to Meet Evolving PC User Requirements_OrenKlein

What If the SSD Were Infinitely Fast?
Cached DRAM data represent infinitely fast drive

Difference between SSD and infinitely fast drive is small!!
• Test system: Intel® CoreTM i7-2600 8MB L3 3.4GHz P67, 4GB DDR3 • DRAM SSD Simulation Test Method: Launch an application to cache it in the dram and then exit & re-launch to measure the application launch time.• Intel S320 300GB SSD is used for SSD. Seagate Momentus* 7200 rpm ST9500420AS 500GB is used for HDD
