I/O Performance

There is little point of having an SSD drive that has blazing sustained reading and writing speeds, if the drive can’t handle reading and writing of small random files. If you intend to use your new SSD drive to store and run your operating system, then the drive must be able to cope with the many small random files that Windows will write to the drive continually. So I feel it is very important to test how many of these random files that a drive can handle in one second. I believe that anything over 1,000 I/O’s per second would be enough for most users running a consumer grade
mainstream PC, and should provide a smooth running system. But obviously, the more I/O’s that a drive can handle, the faster the drive will feel and leave more headroom for those huge multitasking sessions that users sometimes engage in.

The things that I will look at are the total I/O per second and total MB/s.

Partition alignment and sector boundaries

Windows 10 will automatically align a partition to 4k boundaries during partition creation, Windows XP won’t. It is imperative that an SSDs partition is aligned. Windows XP is also restricted to sector boundaries, while Windows 10 will use 4k boundaries if it can. The Toshiba TR200 480GB SSD is 4k boundary aware, and will use these boundaries if possible.
Of course it will also remap LBAs for compatibility with the sector boundaries so that the drive can be used with Windows XP.

IOMeter allows us to set the sector boundaries for conducting the tests, and I have therefore set the sector boundaries at 4K, which means the IOMeter tests are valid for Windows 10 and Windows Vista users. XP users will not be able to obtain such results.

I will provide a screenshot of the tests on the review drive for those of you who like to see the actual test result. All the comparison drive results are represented in the form of graphs.

If any of you would like to see a screenshot from any IOMeter test on a particular drive, please feel free to request one, and I’ll post the screenshot in the forum thread.

All the IOMeter tests create a 20GB data set on the target drive, and each test is run for a duration of 3 minutes.


IOMeter 4K random write test with repeating data.

The first test involves creating continual 4KB random files on the target drive with IOMeter. I use a 4KB file size, as it is believed that Windows will create and modify many of this size of file constantly in the background during a typical Windows session. It is said that most 4K random writes take place at a queue depth of only one.

Queue depth 1

The result is very good.

Queue depth 4

Usually this is the test that I see higher numbers in, but in the case of the Toshiba TR200 I extracted the maximum that the drive could deliver.

4K random write queue depth profile

For this test I used various queue depths from 1 – 32 to give you an idea how this SSD performs at different queue depths. For a normal desktop user, with lightweight multitasking, the queue depth will rarely rise above 2. For heavy multitasking,
the queue depth is unlikely to rise above a value of 8.

The performance of the Toshiba TR200 480GB SSD is good for a DRAM-less TLC SSD.


IOMeter 4K random read test.

If there are many 4k files created, then that must also mean that many 4k files need to be read. This test measures 4k reading performance.

Queue depth 1

The best result that I have seen so far from any SATA SSD that I have tested.

The result here is again just good.

A very good result for the Toshiba TR200
SSD.

This test shows how the review drive scales with increasing queue depths.

The overall performance of the Toshiba TR200 480GB SSD is very good when it comes to read performance.


IOMeter 512KB write test with repeating data.

Sequential writing performance is also very important, and in this test I will be measuring the sequential writing performance of the drive.

Toshiba OCZ TR200 480GB review

Again the write result is not the best, but
it is still good for a DRAM-less SSD.


IOMeter 512KB read test.

This test measures 512k sequential reading performance.

An excellent result for Toshiba TR200 SSD in the read test.


IOMeter Workstation simulation (outstanding I/Os = 64).

When running applications you will find that there is a mixture of small random files and larger sequential files, being created and read. Not only that, it isn’t just one file at a time. In this test I measure a simulated workstation pattern, with a queue depth of 64 (threaded).

Toshiba OCZ TR200 480GB review

The result for the Toshiba TR200 is unimpressive.

Summary

The performance of the Toshiba TR200 is very good when it comes to read speed, write speed is not its strongest point but then again this is an SSD that is aimed at those that are looking for a value for money drive.

Now let’s head to the next page where we will look at how the Toshiba TR200 480GB SSD performs using Anvil’s Storage utilities….
