Reliance Nitro Makes an Impact

Last week one of our customers sent the following evaluation report in an email to Datalight support staff:

“Right now we are in the process of testing the impact of Reliance Nitro in our application. Apparently, we noticed some boost in the performance:  faster write speed, significant speed increase of transaction point creation, faster read speed, and significantly faster directory read (we typically have 1000 files in the directory). So, in conclusion, the overall performance of the system is boosted quite significantly.”

Another real world example of how Reliance Nitro boosts performance in directories with a large number of files. To learn how Reliance Nitro does it, check out the whitepaper.

Reliance and Reliance Nitro

Ever since we announced our high performance file system Reliance Nitro, we have been getting questions on how it compares to the original Reliance file system. Below is a quick-reference table noting some of the differences between the two. For a more detailed comparison (including performance benchmarks), please contact us.

Attributes Reliance Reliance Nitro Recommendation
High performance on large number of files  (100+)   √ If your device stores a large number of files in a single directory, Nitro will perform much faster than Reliance.
High performance on large files   √ Nitro’s extent based design allows it to perform faster on larger files. For sake of this comparison, files can be considered large if they are 10+ times the block size of the device
Frequent transaction points   √ Nitro introduces a new structure called Delta transactions which speed up the time taken to conduct transaction points. Depending on how often you conduct transactions points, Nitro can provide significant advantage
Random I/O performance most critical √ √ Reliance’s block based design provides an advantage on random I/O on small files. On large files both Reliance and Nitro perform equally well on this metric
Sequential I/O  performance most critical   √ Nitro outperforms Reliance on sequential I/O due to its extent based design
Support for Windows Mobile   √ FlashFX Pro 4.0 for Windows Mobile enables a new discard interface that allows Nitro to have much faster write speeds on flash memory
File-size limit 32-bit 64-bit Nitro uses 64-bit variables for file size limits allowing for very large file sizes.
Read-only version √   Reliance currently provides a read-only version called Reliance Reader. Nitro currently does not provide a reader application – this is scheduled for v2
