A Closer Look
Toshiba's packaging only lists a few details about the drive, and doesn't include any performance data.
The Q300 Pro uses the same chassis design we've seen for a few of Toshiba's product generations.
All of the components are on one side of the PCB. The NAND and controller are topped with thermal transfer material to help dissipate heat to the thin metal enclosure.
What about the DRAM buffer we normally see under the hood? As mentioned, this is a DRAM-less design, so the page table map normally cached there is held in flash instead. As a result, you'll see some random performance loss compared to other SSDs using the same flash.
Initial Performance Testing
This is a familiar sight for owners of OCZ SSDs, dating back to the Vertex 4 days. Adaptive SLC technology is notorious for its inconsistent sequential write performance when the drive is full of data. On the right side of the graph is a latency scale. There is a single 2.75ms outlier just before the Q300 Pro changes over from performance mode to a less aggressive state designed to reduce flash wear.
Toshiba's TC358790 controller doesn't give up performance when it reads or writes incompressible data. However, the Q300 with TLC flash does slow down writing incompressible data, just like the Phison S10-based products we've tested.
I ended up skipping this drive and going for another one, and having read this review, I'm kinda glad I skipped it. Seems to be nothing special, and not worth the price.
I guess I'm the only one that prefers reliability over either of those factors, especially for a system drive. All SSD's fall under the fast category, that there is good enough for me. And as far quality is concerned, you get what you pay for to a certain extent.
Trion 100 is horrible, Trion 150 is slightly better but still not great. As far as I'm concerned, only Samsung has a TLC drive even worth considering.
Is this what you're referring to by issues with Arc 100 and Radeon?
Most of the reviews I read on Arc 100 were very positive, so I bought one about a year ago and haven't had any problems with it. Mine is a 240GB model, this article says that the 480GB models were the ones with issues, maybe that's why. Still, so far, this is the only problem I've read about with Arc 100 drives. Are there other issues?
