Conclusion

Announcement: Despite the circumstance that the rating of a product is based on as many objective facts as possible there are factors which can have an influence on a rating after publication. Every autor may perceive data differently over time whereas one possible reason for example is a deeper background knowledge or understanding of certain processes. Certain unforseen market conditions as well as changes have the potential to render a descision made at a certain point in time obsolete.

With the Q300 Pro Toshiba has a solid SSD in its portfolio. What you get is a drive capable of maxing out the SATA interface specifications and apart from that it’s equipped with durable MLC NAND flash memory. Therefore the Q300 Pro is perfectly capable of keeping up with the MLC SATA competition the market has to offer and furthermore the endurance is on an equally competitive level. Apart from that there is a five year warranty plan as well as a spacer which makes the drive compatible with 9.5 millimeter slots. If the Q300 Pro is to become your new boot drive you’ll also like the free copy of NTI’s Echo cloning software which is included in the delivery.

Having a more detailed look at the performance, we see that the Q300 Pro does perfectly well in these tests. According to our measurements sequential throughputs are 524 MB/s in the case of writing and 539 MB/s when testing sequential read capabilities. Also regarding IOPS performance the Q300 Pro does well, managing 77’900/93’900 random write/read IOPS. Looking at IOPS in the case of queue depth 1 we measured 34’400 regarding write and 4’900 regarding read. What we like was the strong sequential performance at QD1 which was 498/443 MB/s write/read.

Meanwhile it’s about time to start talking about the price. The Q300 Pro is available with three different capacities: 128/256/512 GB and these days the corresponding prices are 57/104/197 Euro. This means the price per gigabyte is 0.45/0.41/0.38 Euro respectively. Overall these are not cheap drives. Since the Q300 Pro is based on MLC memory it is to compete with for example the 850 Pro from Samsung and that it’s definitely capable of, coming at almost the same price – the smaller capacity drive are a little bit cheaper and the 512 GB model is tiny bit more – with very well comparable performance.

Overall the Q300 Pro from Toshiba is a solid alterantive when it comes to MLC SSDs, which we can definitely recommend should you be looking for a quick and reliable MLC-based SSD.
