AS SSD BenchmarkFirst up is a pretty new benchmark called
AS SSD Benchmark. A raw translation of the German details below:
The synthetic tests to determine the sequential and random read and write performance of the SSD. These tests are carried out without the use of the operating system caches. In the program Seq-test measures how long it takes to read a 1 GB large file, respectively, to write. In the 4K test will determine the read and write performance for random 4K blocks. The 4K-64-THRD-test corresponds to the 4K procedure except that the read and write operations are spread across 64 threads (typical start of a program).
In all three synthetic test is the test file size of 1GB. Last, still determines the access time of the SSD, the access of which is determined to read through the entire capacity of the SSD (Full Stroke). Write access test only to be met with a 1 GB big test file.
Sequential READ likes large stripe sizes as is visible in the chart above, the difference between 64k and 128k is quite small.
4k performance is surprisingly not highest with 4k stripe, 16k and 8k score the best here. But overall it doesn’t really matter as the difference between them is ~1mb/s throughput.
Threading the 4k test shows no clear winner.
Read access times are all pretty much the same.
Unlike with the sequential read test, the write test doesn’t show clear winners, the 16k stripe offers the best performance here, but the 128k stripe is only ~5mb/s slower;
4k write performance is best on 32k stripe size, while 4k stripe size is worst, 128k doesn’t do that well either.
The threaded 4k performance follows the previous result chart.
Access times are all well below half a millisecond, the differences are bit larger here, 32k stripe performing the best.
In the copy test (menu Tool-copy benchmark) the following test folders are created: (ISO) two large files, programs) (typical program folder with many small files) and games (folder of a game with small and large files. These three folders are copied with a simple copy command of the operating system. The cache is turned on for this test.
The COPY ISO test is all about large files, the largest stripe size performs best and the smaller the stripe size, the lower the average throughput gets.
The result chart with the Program preset is less linear, 128k still in the lead.
The Game COPY performs best with 32k stripe size, going one step lower incurs a large penalty, from 80mb/s to 51.46mb/s with 16k strip size.
Let’s take an average from all the throughput tests, which stripe size does best:
Let us find out if this trend continues in the other benchmarks.
I'll be upgrading soon (or at least after you publish the new Cooler roundup ) and I'm undecided as to an OS drive.
260 Euro can get you a very fast, single, simple to use SSD.
