ASUS ROG RAIDR Express 240GB PCIe SSD Review - Benchmarks - Anvil Storage Utilities

ASUS ROG RAIDR Express 240GB PCIe SSD Review

PCI Express is the future of performance storage, but native PCIe SSDs are rare. Are these RAID controlled SATA products worthy of their high price? (TPE:2357)

Anvil Storage Utilities

 

Version and / or Patch Used: RC6

 

So, what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests; you can run a full test, just the read or the write test, or you can run a single test, i.e. 4K DQ16.

 

Anvil Storage Utilities is not officially available yet, but we've been playing with the beta for several months now. The author, Anvil, has been updating the software steadily on several international forums and is adding new features every couple of months.

 

The software is used several different ways, and to show different aspects for each drive. We've chosen to use this software to show the performance of a drive with two different data sets. The first is with compressible data and the second data set is incompressible data. Several users have requested this data in our SSD reviews.

 

0-Fill Compressible Data

Incompressible Data

The ROG RAIDR Express uses LSI SandForce controllers, so incompressible data flows slower than compressible data. LSI uses this as a feature to increase compressible data performance, and reduce the number of writes to the NAND flash.

 

Read IOPS through Queue Depth Scale

The 64K stripe size holds the SSDs back from breaking records with random data, even at high queue depths. In consumer applications, you want low queue depth performance. The RAIDR does well at QD1, QD2, and QD4.

 

Scaling Write IOPS through Queue Scale

The RAIDR scales well in random write IOPS tests. At QD32, the drive nearly breaks 100K IOPS. Low queue depth IOPS performance is decent, but less than what a single SF-2281 240GB SSD can produce.
