SSD Performance File Copy tests
SSD Performance File Copy tests
In this round of benchmarks we start off with our 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 3GB worth files. We now measure how many seconds it takes to copy the files from the RAMDISK towards the storage unit tested today.
File copy write test - compressed files
For the this 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 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 a RAMDISK) and measure the amount in seconds it takes for the storage unit to deal with it. Lower is obviously better. This SSD needs merely seconds to copy over 4000 files.
As you can see, the SATA controller slowly but steadily is becoming a bottleneck. 6 Seconds is probably the best we'll ever achieve on this platform.
The most basic and simple test, yet everybody uses it on a very regular basis. Above we simply drop a 14 GB compressed file onto the SSD. As you can see the results is roughly 200 MB/sec writes at the end of the file copy sequence.
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.
As you can see all top SSDs however at 9 seconds, this is the fastest the system will go, yup .. our X79 MSI with six cores Core i7 3960X processor is becoming a bottleneck as well. See, now that is why synthetic benchmarks are developed. So let's have a look at a few of them.
In an all new article we test, benchmark and review the Samsung 840 EVO SSD. With the EVO Samsung raises the bar though as the SSD 840 EVO was designed to deliver more speed and even better reliability.
Samsung 840 Pro SSD review
In this article we test, benchmark and review the Samsung 840 Pro SSD. What a stunning piece of technology this is. An SSD that is extremely fast and actually amongst the handful of fastest storage units we have ever tested. Head on over into the review.
Samsung I9300 Galaxy S III review
We review the Samsung I9300 Galaxy S III, Under the motto 'three times is a charm' Samsung releases their Samsung Galaxy S III smartphone. The screen of the S3 is a McDonald's super sized 4.8" Big Mac that tops even the HTC Titan II, yes, the display screen is massive. Will this Ice Cream Sandwich powered device be all we want it to be?
Samsung Spinpoint HD203WI 2TB HDD review
We test the latest Samsung Spinpoint F3 HD203WI HDD. it comes with 2TB that's 2000 GB of storage and sells at an incredible 117 EUR these days. But does it perform at the very least reasonably ?
