This is good.
For sometime now, the speed of SSD drives haven't been blocking part, especially NVMe ones.

The biggest flaw is the price and I would like companies work more aggressive on their prices.

1Tb of SSD (even SATA ones) is still expensive.

Re: Toshiba RC100 is a value optimised M.2 NVMe SSD

My only issue would be if they've cut costs in random performance. I'm always wary of a repeat of the JMicron controller debacle where they sacrificed random performance for big sequential numbers for marketing and when OCZ produced some cheap but awful SSDs for the same reason. This resulted in an utterly crap SSD and is the reason we now test IOPS. The sequential numbers aren't really an issue anymore as you say but the random speeds can certainly bottleneck and I would be very cautious about investing in a "cheap" SSD until these have been fully tested, ideally by Anandtech as they go so in depth it's ludicrous. I don't think there's an issue with the underlying technology anymore - even the cheapest NAND is usually up to the job of a consumer SSD - but there are definitely potential issues surrounding optimisation of the controller, garbage collection and performance when the drive has been written on. Really, the money will be saved in the optimisation of the controller code and this means it's still possible to get a bad SSD.

Those figures are roughly two to three times faster than a SATA SSD drive.

Sorry Hexus, but I think you're wrong there - even post meltdown fix my SATA 2 connected SSD with host buffer gets seq transfer rates in the 3000-4000MB/s range, and while my IOPS are lower, it's not by 2-3x as you claim for a SATA SSD.

That logo is stylised like an OCZ one - I wonder what that means for the OCZ brand as this appears to be a retail drive unlike previous Toshiba-branded ones?

KIANIEL you may be mistaken or just being fooled by the buffering on your ssd. Samsung rapid also does this and if your transfer *fits in* the buffer it will be reported as 1200mb or whatever.
These do sound a bit cheapo and the price is not marvelous, bettered by crucial mx300/mx500 (uk) but presumably it will fall to below 20p/Gb (25cents/Gb) . Certainly a step in the right direction, price-wise.

I readily admit that's RAM buffering, hence why I said 'with host buffer', the point is so is the Hexus quote - it begins 'with its Host Memory Buffer'.
