ASUS is ready for SATA Express - Early tech and performance preview - ASUS ROG RAIDR Express Performance

By: Chris Ramseyer | Editorials in Storage | Posted: Dec 20, 2013 10:10 pm






ATTO Disk Benchmark


Version and / or Patch Used: 2.34


Note: ATTO is a timeless benchmark used to provide manufactures with data used market storage products.




Our default test with ATTO uses a queue depth of 4 (left), but using a queue depth of 10 (right) shows increased performance by simulating higher multitasking.


The ASUS ROG RAIDR running over SATA Express delivers over 750 MB/s both read and write sequential transfers.





Version and / or Patch Used: 3.0 Technical Preview


Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.




Our ROG RAIDR Express was pulled from an extended endurance test so the write speed is much lower than the fresh out of box state. Even in this state, the 4K write performance is quite high, over 70 MB/s.


For this test though, we're focusing on sequential read performance. This test uses incompressible data as well, so it's not the optimal method for showing peak performance with the LSI SandForce architecture.



AIDA64 Random Access Time


Version and / or Patch Used: 1.60


Note: AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.



AIDA Read Latency (64KB)



AIDA Write Latency (64KB)


The read (top) and write (bottom) latency doesn't increase with the extra hop through the adapter. Since SATA Express is PCI Express, we didn't expect to gain any performance by using this format. What it will do though is decrease the cost of materials, and thus decrease the cost of retail products.


The ASUS ROG RAIDR Express also still convers the PCIe signal to SATA after the Marvell RAID controller. The two LSI SandForce controllers are electrically SATA still. Since SF-2281 controllers don't use a DRAM buffer to store table data, the latency is a bit higher than products using a buffer and of course native PCIe devices. We just so happen to have one of those somewhere... let me see if I can find it.
