Toshiba Q300 480 Gigabyte Review
Category : Storage
Published by Marc Büchel on 06.01.16
With their Q300 Toshiba appears to be blowing for attack in the price war. All Q300 drives feature a highly competitive price tag. At this point it's obviously the performance question that remains to be answered and we're curious to find how this drive does in our review.

With the Q300 Toshiba shows their first SSD, which is based on TLC NAND flash memory. Thanks to this choice Toshiba is now able to compete with entry level offerings from Samsung and Crucial. As you might know, TLC memory chips are capable of storing three bits per cell, whereas MLC can only hold two bits. This allows for increased capacity per NAND chip and provides the vendor with more headroom when it comes to pricing, since the production cost is lower.

When it comes to the controller we find Toshibas TC58, or to be even more precise: TC58NC1000GSB-00. Apart from that it has been combined with TH58TET1UDKBAEG NAND flash memory, which, as we already mentioned, is TLC NAND. A closer look at the line-up reveals there are four different models being launched available, where there is a 120GB, a 240GB, a 480GB and a 960GB derivate. A closer look at the bundle you get with the Q300 entry level drives, shows even clearer that Toshiba wants to keep the price low. There is basically only the manual, the warranty terms and a spacer to make drive fit neatly in 9mm 2.5'' expansion slots. Apart from that you get three years warranty.

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.

Toshibas Q300 TLC-SSD comes with an extremely aggressive price tag. Checking the usual price comparison portals we find the following prices per gigabyte: 120GB - 0.40 €/GB, 240GB - 0.29 €/GB, 480GB - 0.25 €/GB, 960GB - 0.29 €/GB. It’s interesting to see that the 480 Gigabyte model offers the lowest price per gigabyte since usually that’s the honor the highest capacity drive. In other words the Q300 is a very cheap SSD but unfortunately some of that is reflected on the performance side.

A closer look at the performance reveals that according to our tests especially the write performance is simply not on a competitive level. Maybe Toshiba is going to release a future firmware update, which is going to correct that by a certain extent. Having a closer look at the numbers we measured 199 MB/s for sequential write and about 34’300 IOPS for random write. A quick look at the sequential read performance shows 544 MB/s and in the case of random read we measured 85’800 IOPS. When it comes to the read performance the world appears to be in perfect order. It’s just a pity that it isn’t regarding write performance.

It looks like Toshiba wants to win market share and in order to do so they’re opening the next round in the price battle. If this drive featured competitive write performance then it would be a great deal, which is precisely why we’re hoping that Toshiba can boost write performance with a firmware update or a future revision of the Q300.

Recommendation


Should you be looking for a very aggressively priced SSD, and should write performance not be of importance to you, then the Q300 can considered.
