AS-SSD Benchmark

Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.

Beginning with sequential read and write performance, the ADATA S511 Solid State Drive AS511S3 produced 514.57 MB/s read speed, and 152.87 MB/s write performance. Because this benchmark uses compressed data, sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this section, we will concentrate on the operational IOPS performance using compressed data. Single-threaded 4K IOPS performance delivers 17.84 MB/s read and 59.24 MB/s write, while the 64-thread 4K reads recorded 109.00 MB/s and write performance was 145.55 MB/s.

AS-SSD 64-thread 4KB IOPS performance results are displayed in the chart below, which compares several enthusiast-level storage products currently on the market. The chart is sorted by total combined performance, which helps to illustrate which products offer the best operational input/output under load:

In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.

"SandForce claims that the 2200 series has a 0% minimum over-provisioning improvement, which could open up additional storage space if the remaining capacity made it necessary to complete a write cycle."

The second half of that sentence is not a logical conclusion to the first. If something has 0% improvement, it means it has not improved at all. It does not facilitate a declaration it is the same technology although that is usually the case.

You're reading it wrong. SandForce SSDs previously had a 7% or more over-provisioning, and now they offer SSDs with 0% over-provisioning, which is an improvement.

I am not reading it wrong, it was structured comfusing for hte simple. 9% change means nothing changed.

As a matter of cat I have a MAX IOPS drive up for review as I type. And guess what.

One NAND chips worth of data density was set aside for OP and EC. 16 times 16GB = 256 GB not 240...


Only trying to help.

*edit also it means it has not decreased at all. (sorry that explains the logic in the PC community that nothing changed architecturally, it neither improved nor degraded).
