SandForce SF-1500 Performance
The ATTO Disk Benchmark 2.34 program measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. ATTO Disk Benchmark requires that an active partition be set on the drive being tested, and for testing purposes we format using NTFS after SSD partition alignment. The charted results illustrate bandwidth speed using various file size chunks, and can be used as a general performance indicator.
HD Tune is a low-level test that will not operate on a drive which contains a partition, so Benchmark Reviews uses DISKPART to prepare hardware and remove any partitions before conducting these tests. Random Access tests are divided into 512b, 4KB, 64KB, 1MB and random size test files sizes. The Random Access test measures the performance of random read or write operations. The amount of data which will be read varies from 512 bytes to 1 MB. Performance is reported in operations per second (IOPS), average access time, and average speed. Because it is our intent to compare one product against another, Benchmark Reviews has focused on random transfer size IOPS performance.
Using the OCZ Toolbox utility to format a +1 alignment to the drive, ATTO reported a maximum read-speed of 250 MBps and a respectable 263 MBps write performance. For operational input/output, HD Tune reports 16,355 IOPS for 4KB reads and 13,429 IOPS for write-to operations. Because of the impressive I/O performance, the SandForce SF1500 SSD processor is best suited for high-transaction enterprise environments.
In the coming months, Benchmark Reviews will test several new Solid State Drive products based on SandForce SSD processors. Our entire collection of SSD articles is available in the Benchmark Reviews Featured Reviews: Storage section.
