QuickBench is a recent addition to our tool chest and we use it as it does a great job validating ATTO scores by measuring the transfer speeds of increasingly larger files. For our purposes, we have tested in standard and extended file sizes. Performance highs are displayed in blue while lows are displayed in brown.
Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we thought we might cheat just a bit and throw in an ‘optimized’ result on the right (CPU ‘C” States turned off).
The performance we are seeing is the highest we have ever seen from a single form factor solid state drive. Whats even more intriguing is the fact that the XP941 just may be one of the smallest SSDs we have tested yet.
Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data. AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
Given our first glimpse at IOPS, this may be a bit lower than the listed 122K, however, 98779 is a great IOPS result. The AS SSD Copy Bench was even better, giving us the one of the highest results we have ever seen in ISO transfer, regardless of the media tested:
