AS determines the performance of Solid State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are 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 all synthetic tests the test file size is 1GB. AS can also determine the access time of the SSD, the access of which the drive is determined to read through the entire capacity of the SSD (Full Stroke). The write access test is only to be met with a 1 GB big test file. At the end of the tests three values for the read and write as well as the overall performance will be issued. In addition to the calculated values which are shown in MB/s, they are also represented in IO per seconds (IOPS).
Note: AS SSD is a great benchmark for many tests, but since Crystal Disk Mark covers a broader range of 4K tests and HD Tune Pro covering sequential speeds, we will only use the Copy Benchmark from AS SSD.
- Copy Benchmark USB 2.0
For the most part all of the USB 2.0 drives cost within a few dollars of each other for the same capacity. Some drives, like the OCZ Diesel, are very cheap; just 15.99 for the 8GB model. On the high end the available drives in our roundup we found the 8GB Lexar JumpDrive TwistTurn at Newegg for 23.79. Going on price alone is foolish, though, so let's take a look at some real performance data. We'll get into pricing more in the conclusion.
The chart above uses three models to gain insight into the performance of each drive. As you can see, each drive performs differently with each type of software being transferred. The Program Test uses many small files, the ISO Test is one very large file and the game test is a mix between small and large files.
When it comes to performance, the Silicon Power LuxMini 920 is the fastest drive at all three tests. The 920 is very fast, one of the fastest USB 2.0 drives we have ever seen. A close second is the Patriot Memory Xporter Rage. These are the two top of the class speed demons, but there are other categories to consider as well. The Patriot Magnum is one of the few drives in this round up that is available in 128GB capacity; most of the others top out at 32GB and a few go up to 64GB. The Magnum, even though it is a massive drive, is still very fast; third on the list.
- Copy Benchmark USB 3.0
This was our first year of seeing USB 3.0 drives in our annual Thumb Drive Round Up and all three couldn't have been designed more different. ADATA's N005 is what we would consider a traditional thumb drive. The N005 is a little longer than most thumb drives, but other than that the shape of the drive is unmistakable.
OCZ's Enyo looks nothing like a thumb drive and even uses an external cable for connectivity. The Enyo is portable, but it isn't something you are going to stick on a keychain. Last but not least is the Super Talent SuperCrypt. The SuperCrypt is in the shape of a thumb drive, but is at least 2x the size of any other traditional USB 2.0 drive we looked at today.
When it comes to transfer performance the OCZ Enyo tops out our USB 3.0 tests. This really isn't a big surprise since it is based on proven SSD technology and for the most part is a solid state drive. The ADATA N005 was faster than the USB 2.0 drives, but much slower than what we expected. Super Talent's SuperCrypt was the mixed bag from the group. The SuperCrypt did a very good job with large ISO files, but the Game Test had it being outperformed by the fastest USB 2.0 drive in the round up.
