Did you expect to see a DRAMless, actually a BGA DRAMless, SSD perform as well as the new Toshiba BG4?
To be honest, I didn't. After looking at the results, I went back to see the specifications and the notes from a briefing from nearly a year ago. I was convinced Toshiba changed the build and added a DRAM die in the package. We can confirm the BG4 is still a DRAMless design.
The drive is very quick for what it is, and most users would have a difficult time justifying upgrading a notebook with this drive inside. That's very high praise for any OEM-style SSD. Sadly, at this time, Toshiba doesn't have any plans to bring this drive to market as an upgrade product sold through retail channels. In the future, the drive may come to market, likely under the RC200 name like the BG3. Clearly, the BG4 would be a more competitive product with the new PCIe 3.0 x4 interface compared to the RC100 with only two PCIe lanes.
