Toshiba OCZ VX500 SSD with MLC-NAND review

With the VX500 series Toshiba presents a completely new range of mainstream SSD models. The new SSDs of the VX500 series should be characterized by a good reading performance at an attractive price and delivering attractive results just in practice. So exactly what you want from a good and cheap SSD.

The new Toshiba VX500 is positioned between the Enthusiast Series OCZ RD400 and the entry-level OCZ TR150 series . The SATA-6 Gbit interface is used for optimum compatibility and a wide range of applications. As an M-2 version the SSD will probably not be offered. Therefore you have to do without the fast NVMe standard. The SSDs are held in the usual 2.5 inch format and can be installed in most notebooks.

Like all new OCZ models, the SSDs of the VX500 series are now distributed under the brand name OCZ but with Toshiba as a manufacturer. The release offers four different models with 128, 256, 512 and 1,024 gigabytes of storage capacity. For the test, the price was especially attractive 512-GB version provided. Depending on the size of the SSD, the performance differences between the different memory sizes are quite measurable.

All SSDs of the VX500 series offer a maximum reading speed of 550 MB / s. The write speed is between 485 and 515 MB / s. According to Toshiba, the maximum IOPS is read at the maximum of 62,000 and the write speed is 49,000. For versions with 256 to 1,024 gigabytes, the maximum IOPS is reading at 90,000 to 92,000 and writing 58,000 to 65,000. The 512Gbyte model we tested has a TBW (Terrabytes Written) of 296, which means that the SSD can theoretically be completed almost 600 times without the problem of durability.

Toshiba installed a controller of the OCZ VX500, not specified or described, in the SSDs of the OCZ VX500. 15-nm MLC-NAND, which can store a maximum of two bits per flash cell, is used as the flash memory. The advantage of MLC-NAND compared to TLC-NAND memory is faster write and reader data, but the memory is often somewhat more expensive compared to TLC-NAND because more NAND flash cells have to be installed for the same memory capacity.

In the case of the new SSD, Toshiba turns from the old rather heavy OCZ design and uses similar enclosures as Toshiba’s SSDs, such as the Toshiba Q300 Pro SSD we tested last .

How the new OCZ VX500 from Toshiba beats and whether the surcharge compared to the value series OCZ TR150 is worth, we will clarify on the next pages of our review. So go on to the various benchmarks.

Benchmark AS SSD

The AS SSD benchmark is a benchmark specifically for SSDs, and it also performs these specialized tests similar to the Crystaldiskmark, but still offers a 4K-64 thread and an interesting file copy test that is quick and easy to perform. The data can be output in the AS SSD in MB / s or IOPS.


In the following test, the SSD is “edited” with different patterns. In this case, write and read accesses on the SSD take place according to a particular pattern. Each test takes 5 minutes, and the data throughput is output by a curve.

The tests are much more demanding than typical SSD benchmarks and are more oriented to use in professional workstations or servers and less to the typical desktop or gaming PCs. We would like to point out that the Trion 150 is not intended for enterprise use. We are still testing the test as a comparison to other tested SSDs, as they give a good insight into performance in more demanding applications.

The following patterns are used.

Workstation: read 70% write 30% – sequential 20% random 80%
Database: read 90% write 10% – sequential 10% random 90%
FileServer: read 80% write 20% – sequential 0% random 100%
Webserver: read 100% write 0% – sequential 0% random 100%
The pattern tests show that the differences between the SSDs are much lower than in the theoretical test. If read and write access is interdependent and is not strictly separated from one another, the performance of the SSDs generally falls significantly short of the read / write benchmarks. The various patterns can also be multiplied by so-called “workers” or “threads” so as to increase the load on the SSD. In the following, we run the tests with 1.2 and 4 threads each to assess the fluctuations in the performance and the multithread capabilities of the SSDs. Especially the tests with several threads according to a judgment in the server area rather than the typical desktop use.


With the OCZ VX500, Toshiba is re-emerging in the mainstream segment. It is clear that the OCZ VX500 is not the direct successor of the OCZ VT180, even if it reaches the end-of-life status shortly and the VX500 probably occupies the place of the VT180. As a successor of the fast VT180 one can rather look at the RD400, because this is not limited by the M.2 and NVMe by the SATA interface.

Even though it is only a SATA SSD, the 512-gigabyte version of the OCZ VX500 provides a decent picture in our benchmarks. Overall, it just lands just behind the VT180 (Vector 180). More favorable SSDs models with TLC memory beats the VX500 generally clear.

Interesting is that the VX500 in the writing is much slower, but in the practice benchmarks faster than the VT180 is. In the benchmarks like PC Mark 8 and PC Mark 7, the Toshiba OCZ VX 500 can play their muscles and shows here comparable results as the Toshiba Q300 Pro. Even the so popular Samsung 850 Pro and Evo leaves it often behind it.

The maximum reading and writing rate of 550 MB / s or 515 MB / s corresponds to today’s standard of SSDs with SATA-6-GBps connection and is therefore no special feature anymore. In our Stresstest the performance of the OCZ VX500 SSD 512 gigabytes of storage space towards the end somewhat more clearly, but initially provides quite good results, so that in practice in typical desktop use synonymous of it will not notice anything.

A hardware encryption must be dispensed with the SSDs of the VX500 series. however all standard features for performance enhancements such as TRIM and garbage collection are of course available. The consumption of the new SSDs of the VX500 series is only 3.4 watts in active operation and decreases in DevSlp to only five milliwatt. The low consumption is particularly suitable for notebook users with battery operation. The SSD itself weighs only 52 grams and is held in a commercial 2.5 inch format with the dimensions of 100 mm x 69.85 mm x 7.00 mm.

With a TBW of 296, the write performance of the OCZ VX500 with 512 gigabytes of storage is up to 162 gigabytes per day for the warranty period of five years and can thus be described as quite robust. Thanks to Toshiba’s own production, the same quality of the flash memory is guaranteed to a high degree.

As with all Toshiba brand OCZ SSDs, the VX500 Series also offers the advanced warranty of the Advanced Warranty Program. The warranty processing is handled via the serial number of the SSD, so the retention of the cash receipt is no longer required. As a replacement for a defect within the five-year warranty, the manufacturer offers a completely new SSD as a replacement. The replacement SSD is made available to the user before the upload, which means that the transfer of files to the new drive is theoretically still possible. The support of OCZ and Toshiba also strives for a fast processing of all warranty claims so that the replacement SSD can be sent to the user on the next working day. There is currently no other manufacturer of SSDs offering such a high level of service.

For easy migration of data to the SSD or backups, Toshiba also provides a version of Acronis True Image 2016 for the OCZ VX500 with Windows 10 Support free of charge. In addition, the SSD utility of OCZ can be used for maintenance/firmware updates of the SSD. The new OCZ tool also provides its own functions for the support.

At the price, Toshiba suggests moderate sounds for the new OCZ VX500. For example, the EIAs for 128 GB at 65 Euro, for 256 GB at 95 Euro, for 512 GB at 145 Euro and for the large 1024 GB model at 355 Euro. In particular, the popular 512 GB models are priced on very solid legs and remain the most interesting version. The SSD also appears to be cheaper than the comparable Toshiba Q300 Pro model. In addition, the OCZ VX500 with the pre-exchange service provides somewhat better warranty conditions.

The new OCZ VX500 is particularly interesting for users who, in addition to an excellent performance with standard applications at an attractive price paired with good warranty performance and reliability. If the pure continuous writing speed plays a subordinate role, in normal mainstream use this is always the case, then the OCZ VX500 is clearly a recommendation.
