Test Setup
Testing was accomplished on a blank formatted SSD. The drive used in our tests was first securely erased via software provided by their respective manufacturer and then updated to their latest firmware. For the test I tested the drive with as an active drive and between each test I ran TRIM and rebooted the system.
VX500 Performance Testing
Just as a quick reminder of the advertised specifications from Toshiba OCZ VX500 512gb Solid State Drive. Sequential read 550 MB/s and sequential write 515 MB/s.
ATTO Disk Benchmark v3.05
The ATTO Disk Benchmark application was designed to measure your storage systems performance with transfer sizes and test lengths for reads and write speeds.Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. You can test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives.
ATTO Disk Benchmark Features:
- Transfer sizes from 512KB to 8MB
- Transfer lengths from 64KB to 2GB
- Support for overlapped I/O Supports a variety of queue depths
- I/O comparisons with various test patterns
- Timed mode allows continuous testing
- Non-destructive performance measurement on formatted drives.
Results: Max Sequential read 553 MB/s and sequential write 520 MB/s
Our tested speeds exceeded the rated speeds advertised!
AS SSD Benchmark 1.9.5986
The AS SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains six synthetic and three copy tests.The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache.
In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Thrd 4K procedure except that the read and write operations are distributed to 64 threads. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The additional compression test can measure the power of the SSD in response to compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.In the first three synthetic tests and the compression test, the size of the test file 1 GB.
Finally the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. The write access test, however, is done with a 1 GB big test file.
Results: Max Sequential read 501.1 MB/s and sequential write 462.6 MB/s
AS SSD always has seem to bench lower scores than every other bench mark out there so I am not concerned seeing these results.
Crystal Disk Mark
CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds.
CrystalDiskMark Features:
- Measure sequential reads/writes speed
- Measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed
- Select test data (Random, 0Fill, 1Fill)
- Theme support
- Multi-Language support
Results: Max Sequential read 552.2 MB/s and sequential write 519.2 MB/s
Our tested read speed once again exceeded the rated read speed as advertised and the write speed comes in right where it needs to be!
AS SSD Benchmark Graph
The OCZ VX500 512GB brought to you by Toshiba exceeded our expectations in our testing suite and blew by the competition! Let us cover a few final thoughts and conclusion of our review.
