Desktop Test System
All 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.
Our testing includes charting the performance of a single drive, as well as a RAID 0 array of our test subject/s. We are utilizing Windows 8.1 64 Bit OS for all of our testing.
This report will focus mainly on drive scaling in RAID 0, and what a kind of storage performance you will get as you add drives to your Haswell based array. We won't be doing any secondary attached volume testing in this review because there is no way to be sure we could serve up data fast enough from our OS Volume to any array over three drives for our data transfer testing. We're going to post screen shots of our six drive array's performance, and chart a single drive, as well as two through six drive arrays.
ATTO Baseline Performance
Version and / or Patch Used: 2.47
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Transfers are excellent, ramping up quickly, and staying strong throughout. Write transfers are full speed by 8k.
Three through six drive arrays all max out Haswell's PCH write bandwidth.
Our four drive array displays the best performance curve of all our arrays. Performance of our five and six drive arrays doesn't ramp up as quickly, but they finish slightly ahead by the end of the test.
