Page 4 - Benchmark: ATTO Disk Benchmark

About ATTO Disk Benchmark

As the industry's leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark for Windows to help measure storage system performance. As one of the top tools in the industry Disk Benchmark identifies performance in hard drives, solid state drives, RAID arrays as well as the host connection to attached storage. Use the tool that top drive manufacturers use to build and test drives.

ATTO Disk Benchmark for Windows can be used to test any OEM RAID controller, storage controller, host adapter, hard drive or SSD drive, and notice that ATTO products consistently provide the highest level of performance to your storage.

Following up next are our usual ATTO read and write tests. ATTO is an often-quoted benchmark because it is easy to use and accurate. ATTO uses easily compressible data, so compression-heavy controllers will perform very well here. As manufacturer peak read and write performance ratings are usually achievable using ATTO, whether a drive lives up to its marketing claims or not can be validated by this program. Lexar claims that the NQ100 480GB has a maximum read speed of 550MB/s and "lower" write speeds. The tested read results came close to the advertised figure, peaking at 539MB/s. The maximum write speed came out to 513MB/s, which I suppose is accurate to the advertised "lower" write speed. Taking a closer look below the curve, the ramp-up write speed is quite fast at moderate file sizes, specifically from 16KB to 256KB. From 16KB to 64KB, the NQ100 480GB was at the top of the pack and only fell behind the UV500 240GB from 128KB to 256KB. However, the NQ100 480GB fell behind the competition at very small and very large file sizes. The ramp-up read speed did not fare any better and was actually the slowest among all the drives shown, only tying with the UV500 240GB for the slowest maximum read speed. While both the peak read and write speeds of the Lexar NQ100 480GB fell behind the other tested drives, it should be noted that all the peak speeds shown are generally close in magnitude. The peak write speed of 513 MB/s is not a terrible measure either, so I still find it strange that Lexar decided not to share this piece of information.
