4. SiSoftware Sandra 2005

SiSoftware Sandra is a 32 and 64-bit Windows system analyser that includes benchmarking, testing and listing modules. It tries to go beyond other utilities to show you more of what is really going on under the hood so you draw comparisons at both a high and low-level in a single product.

You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, ODBC Connections, USB2, Firewire etc. You can save/print/fax/e-mail/post/upload or insert into ADO/ODBC databases reports in text, HTML, XML, SMS/DMI or RPT format.

This version supports multiple sources of information gathering including: remote computers, PDAs, Smart Phones, ADO/ODBC databases or saved system reports. All benchmarks are optimised for both SMP & SMT (Hyper-Threading), up to 32/64 CPUs depending on the platform.

File system Benchmark

  • The "File system Benchmark" tests how your drive(s) and controller(s) compare to other devices in a typical system:

· Read Test: Buffered, Random, Sequential
· Write Test: Buffered, Random, Sequential
· Seek Test

The "Drive Index" mark is a composite figure representing an overall performance rating based on the average of the read, write, and seek tests, and file and cache size. The Drive Index is intended to represent drive performance under typical use in a PC. A larger number means better performance. The weighting of the results is not equal and represents the distribution of different files sizes as used on these devices (obtained through field research).

Similar performance from both drives, with the Fujitsu being slightly better.

Removable Storage/Flash Benchmark

  • The "Compact Flash" typical usage model for these devices is File operations, such as Writing a file to the device, reading a file from it, and deleting a file. This benchmark exercises the devices in terms of these operations (to measure the “raw” cluster level performance of the device, it is recommended to also test it by means of the File System Benchmark module). The following characteristics are measured for each of the four representative file sizes of 512 Bytes (representing a minimal single data cluster file), 32kB, 256kB and 2MB. The weighting of the results is not equal and it represents the distribution of different files sizes as used on these devices (obtained through field research). For each of the four file sizes, a Combined Index is then calculated, stating the combined performance in terms of Combined Operations Per Second, with respect to a mix of write, read and delete operations.
  • Combined Device Index: is a composite figure representing an overall performance rating based on the average of the Combined Index figures over the four file sizes. (Higher is better, i.e. better performance)
  • Endurance Factor: is a figure representing the Wear and Life Expectancy of flash devices; this is obtained by dividing the average performance (normal condition, i.e. sequential write) to the lowest performance (high-stress condition, i.e. same block re-write). It measures the relative improvement of endurance caused by the wear leveling or flash management algorithm; the absolute endurance of a device (i.e. its expected life-time) is directly dependent, in addition to this Endurance Factor, on the nominal manufacturer rating of maximum erase/reprogram cycles, which is typically 100,000+ for SLC and 10,000+ for MLC devices. (Higher is better, i.e. longer life-time for the device)

Once more, there is a small difference in performance between the two tested drives. The smaller capacity might be the reason for this.
