SSD Performance RW File Copy tests
In this round of benchmarks we start off with our two latest additions in our test suite, real-world file copy tests. Currently certain controllers benefit from compressed files, while others don't. Certain storage units hate small files, others work well with it. So it only makes sense to do some manual tests on that.
Any storage unit's nightmare, whether that is an HDD or SSD, is storing really small files as fast as possible. So on our Test PC we created a RAMDISK partition (we can't use an SSD/HDD here as it would be a bottleneck) in which we install roughly 500MB worth of text files, highly compressible. We now measure how many seconds it takes to copy the files from the RAMDISK towards the storage unit tested today.
The crucial factor here is that we copy many small files that can be compressed. But we made the files so small that the file-system will simply choke up. Make no mistake, this test is ridiculous. Over time results will build up of course.
So in the above chart we take 0,52 GB of random text files sized from just merely bytes (the vast majority) up-to 250KB. In total copy queues up over 113,586 files in this test, and these are being copied from the RAMDISK towards the storage unit in the number of minutes shown above. Lower is obviously better.
Now the bottleneck is the file-system and this test is bizarre (you basically drag a hundred-thirteen-thousand miniscule files and drop them onto the storage solution). The difference will be marginal, even compared to HDDs as NAND based flash solutions behave very similar.
Bing a memory cache based SSD, the Corsair Performance Pro performs really good.
File copy write test - Slightly larger compressed files.
For the second real world file-copy test we take compressed data, like small JPG and MP3 files. We have them in random sizes from less than one KB up-to slightly larger 2MB files to emulate MP3 copying better (which most of you can relate to a notch better).
So we know that once we pass 16/32KB sizes, SSDs really haul ass and speed up almost exponentially. Hence we increased the total workload here towards 3 GB with 4272 compressed files in total, with a maximum files-size of 2MB. We drop all these MP3/JPG files onto the drive, copied from the RAMDISK and measure the amount in seconds it takes for the storage unit to deal with it. Again, the files are being copied from the RAMDISK in the amount of seconds you see above towards the tested storage unit, lower is obviously better.
We already had an indication that sustained performance of compressed data should perform really well on the product, and so it does.
Performance Game load times
Here at Guru3D.com the audience is catered to gamers. And as such I like to start off with three real world performance game tests for a change.
We take the Alien Versus Predator benchmark and run it a couple of times. From the moment we click on the icon and load up the game to the moment the benchmark start to run is what we are looking at for load time in seconds.
We just added this test, so in the future results will build up with more and more storage units.
We review a new chassis from Corsair, it Obsidian 350D. It is the mini-me version of the new Obsidian 900D chassis. Not mid, not full, mini and this intended for small form factor PCs. Now the product might be tagged as mini, the details and features however are grand. Armed with a price much better then the 900D this might be the product a lot of you are on the lookout for.
Corsair Voyager Air review
We review the Voyager Air, it is a portable storage unit allows you to connect it towards USB 3.0 and Ethernet, but it also includes WIFI support and it actually comes on a 100 GB HDD model as well. This great looking device might just be what the doctor to move or stream your content from.
Corsair Obsidian 900D review
We test and review the all new Corsair Obsidian 900D chassis. Not, mid, not full heck, this is a super tower. Probably one of the biggest products you have seen to date. It is highly configurable has hidden options in every corner and a craftsmanship that will stun you.
Corsair H90 review
A test and review the Corsair H90 liquid cooler. The Hydro Series H90 is Corsairs first 140mm Liquid Cooling solution that is bound to draw some impressive heat from your processor.
