The majority of our testing will be done with our test drive/array as our boot volume. Our boot volume is 75% full for all OS Disk "C" drive testing, to mimic a typical consumer OS volume implementation. We're using 64K stripes for all our arrays. Write caching is enabled.

Typically, SSD's that have capacities of 240GB or larger have far better write performance than smaller drives. The EVO we are testing today has a capacity of over 240GB and as such has superior write performance. The EVO's "Turbo Write" technology further enhances write performance.

 

A single 500GB EVO has nearly equivalent write performance to a pair of 120GB drives. A Pair of EVO's in RAID can write at over 1GB per second.

 

Both our RAID arrays have read performances that easily exceed 1GB per second.
