Is there an equivalent of RAID in this technology or does this 'come for free' with the use of multiple memory devices and an smart controller?

And after it fails, is there a mechanism to retrieve data?

By maintaining the 2.5 inch form factor, they make it easier for PC manufacturers to offer an option of either HDD or SSD in what is otherwise the same PC. Then the customer can decide the economic tradeoff between cost and speed based on individual needs.

soon we will see the demise of HDD's in the PCs. As the demand increase the cost for SSD's will definitely come down.

Stick to a 2.5 inch format so as to be a drop in replacement for an HD. This way the PC maker doesn't have to re-design the internal mechanics, create new (expensive) molds etc.

"The unit is available in capacities up to 512-Gbyte and comes with a 6-Gbyte per second SATA interface and it comes in a 2.5-inches form-factor but at only 9.5-mm or 7-mm deep. " I am not sure why they stick to this 2.5inch formfactor for SSDs, when they can make it really much smaller. Because of the form factor, ultra thin laptops like macbook air, directly uses a smaller PCB with a few flash chips sticked on it. And this reduces the upgrade options for the notebook.

That is worth pointing out. In that case, the non-volatility benefit is not obvious anymore.

"The power consumption at 3.3V is 150-mW in active mode and 75-mW on standby." This could be due to "use of continuous background error checking and advanced NAND recovery mechanisms". Worth it?

Very hard to see the innovation here. Yet, there are things they may be seeing differently.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
