The wait for the higher-density V-NAND is because Samsung insists upon making sure the 950 Pros are single-sided only; they could have released a 1TB at the same time as the 512GBs, but it would have to have been double-sided.

(source)Anandtech said:The PCIe 3.0 x4 interface certainly gives the drive plenty of headroom. And based on the performance of the 950 Pro, it's doubtful that an M.2 drive will be able to saturate the interface before running in to thermal limits while still remaining in the same form factor. Future drives in this area will probably have to implement aggressive power saving techniques in order to keep average temperatures low enough to accommodate bursts of activity. The 950 Pro and the PCIe ecosystem in general have a lot to improve upon here.
The M.2 form factor is also constraining drive capacities to a degree. The back side of the 950 Pro is empty so a 1TB model should be geometrically possible if not economical, but the extra NAND packages would be even more susceptible to thermal problems. Samsung is instead choosing to wait for their 256Gb third-generation V-NAND before offering a larger model of the 950 Pro.
Ah yes, I remember the reason now--with all the "throttling" issues. Thanks for reminding me!
There is one potential cause for concern with the 950 Pro drive, and thats thermal throttling. In short, the amount of data that the drive and controller can process in a short amount of time is staggering. Under heavy loads, however, it can cause the controller to heat up to the point where it has to reduce clock speeds in order to keep temperatures in check. For normal workloads, this doesnt happen much and even when it does its not particularly noticeable.
Thus is from a review on Maximum PC for the Samsung 950 Pro:

what does that mean? If your referring to current gen the only reason they throttle is because people have crap cases.
Well, "crap" airflow, technically
But Samsung has to design for the worst-case scenario...
no its plausibleI am looking forward to the release of the 1TB in hopes that the 512GB might go down a little in price. Is that wishful thinking?
Early 2016 my ass. Damn it's already mid-2016 and not even news about the 4tb evo/pro and 1tb 950 pro.
no further updates? I know last statement was September but wasn't sure if new news was released and i missed it.Samsung has released new SSDs in very early July in previous years, so you might see something then.

at this point it'll be more worth buying Optane :/Yeah, nothing...
that source is dumb...it was always know 1TB was waiting on 48 layer derp derp. What is news is they are re-branding it instead of calling it a 950PRO like they first intended.
edrive?I'd like to know when the firmware update to allow e-drive will be coming to the rest of the range (if it ever will)
Most SSD's hardware encrypt the data written to the NAND by default, but the keys are stored in the controller in such a way that it's transparent to the rest of the computer. eDrive has Bittlocker manage the key and store it in the TPM rather than encrypting/decrypting the data in software. The performance hit from Bittlocker isn't huge, but being able to use eDrive would mean no overhead at all compared to an unencrypted drive.edrive?
Samsung does have the OEM edition of the 960 available already...Samsung SM961 1TB M.2 NVMe PCIe SSD Review
About $550 US from RamCity.
