Some require higher IOPS (for random access), others demand high throughput in MB/s (sequential access).
Among the topics are practice for simple computing, applications of linear lists for sequential access, programming by tree structure, applications of classical trees, and algorithms of bipartite graphs and flow networks.
The results are divided into two groups: random access and sequential access. The files will be accessed one by one in sequential access.
Small executable and data files tend to have temporal access patterns, whereas large executable and data files tend to have sequential access patterns.
The Fixstars SSD-6000M supports SATA 6Gbps, providing read speeds of up to 540 MB/s, and write speeds of up to 520MB/s for sequential access. As with the Fixstars SSD-3000M, the proprietary SSD controller enables a stable, high I/O performance for sequential access throughout the lifetime of the drive.
(2) Highest performance in class: Based on the SPC- Benchmark-1(TM), which measures random access performance and the SPC- Benchmark-2(TM), which measures sequential access performance.
And that, in turn, will negatively impact the performance of sequential access because more I/O will be required to read the "same" number of rows.
The scroll was typically read aloud to an owner by someone in his employment and was convenient only for sequential access to contents.
Other topics include an information retrieval method based on sequential access patterns, a parallel model of evolutionary computing based on genetic algorithms, a blind particle filtering algorithm in a flat fading channel, and cognitive radio spectrum detection in OFDM systems.
A sequential access retrieves an object from a sorted data source while a random access returns the score from a given object identifier.
