Toshiba Q300 SSD review: Not the bargain it should be

Jon L. Jacobi | Nov. 10, 2015
It's decent with smaller files but the Q300 gasses out on large data sets.

Then there were our real-world 20GB copy tests, where the Q300 was also soundly spanked by Kingston’s HyperX Savage SSD (and every other MLC-based drive we’ve tested recently)...

To show you just how slow the Q300 SSD actually is writing large data sets, below it is compared to an external Seagate Backup Plus Fast USB3.0 (two traditional hard drives in a RAID 0 configuration). The Seagate actually beat the Q300 writing our single large 20GB file! Good grief...

Please note that all testing was done with the 960GB model of the Q300. The numbers would be even worse with the lower capacities with their smaller caches (assuming the Q300 is like the Trion).

I can hear some people saying “When am I ever going to copy that amount of data?” Maybe you never will. Maybe you will never back up to the Q300, copy a Blu-ray movie structure there, work with 1080p or 2160p video, or transfer your operating system to it. But I’m guessing you might, and you will not be happy about it as you ruminate over how you could’ve bought a cheaper drive that doesn’t suffer the same slow-down.

If it were half the price, the Q300 might qualify as a bargain. It’s performance woes aren’t an everyday occurrence for most users. Credit: Toshiba

Don’t buy it at current prices

Only buy this drive or another TLC drive (Samsung 850 EVO excepted) if there are serious savings involved. At this point there aren’t. So until prices drop, the Q300 and the Trion that the Toshiba put out under the formerly unsullied OCZ banner are two drives that should be grounded in your “no-buy zone.”  

Avoid them entirely if you perform even moderately disk-intensive work.
