PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
Our file creation and copy tests highlight some of the differences between SF behavior when running in Sync (Vertex 3) vs. Async (Agility 3) modes. Remember that these are test completion times – lower is better, meaning Agility 3 *beat* Vertex 3 in a fair chunk of these tests (but not all).
I tested a Vertex 2 120GB
I tested a Vertex 2 120GB against an Agility 3 120GB on an X58 (3Gb) and found them to be very close in most things with the Vertex having a slight advantage except for Random Read/Write 4KB (QD=1) and burst speeds.
I realize that the Agility 3 is designed for 6Gb so my test is not entirely fair.
dude, they both peak at
dude, they both peak at 275mb/s which is max speed for sata 3gbps…its not exactly a wonder why u cant see much of a difference when you put a 550mb drive on a 275mb line and compare it with a 275mb drive
Allyn: another good review.
Allyn: another good review. I’m just adding this Comment to remind you about our private correspondence, in which we discussed a test to determine if TRIM works on OS software RAIDs when the RAID members are formatted as “dynamic” partitions.
Cheers and … thanks for the great reviews!
