Power Consumption
The Extreme Pro supports both DevSLP and slumber power. We are still working on a way to measure DevSLP power but in the mean time, we have to rely on slumber power measurements. Slumber power consumption is quite average -- it's not the most efficient drive we have tested but 100mW is pretty typical for a high performance SSD. What is awesome, however, is the load power consumption, because the drive doesn't exceed 3W in any case and stays at around 2W when under random write workload. Out of the high performance SSDs, the Extreme Pro is definitely the most power efficient because it supports DevSLP and slumber states, yet the load power consumption is very low too.

The only improvements are idle power consumption and support for Low-Power DDR3, and this isn't really a mobile-targeted drive.Oyster - Monday, June 16, 2014 - link
10 years warranty. Love it. L.O.V.E. I.T. Thank you, SanDisk, for setting this trend. I'll surely wait, but I think this is exactly what I need for my next build.10 years... OMFG! Drool!

It's a great warranty but I think ssds potential failure points are less than an hdd. (my speculation).When I saw that though it definitely peaked my interest. Would have purchased this drive if it had been an option as that warranty would definitely make me feel better as I hold onto my hardware for a long time.

I'd still choose the MX100 over this any day. It's not like these drives are falling apart everywhere. And if you save the price difference between these drives you could use it to buy something significantly better in a few years, should the MX100 have failed by then (I wouldn't expect it to).nathanddrews - Tuesday, June 17, 2014 - link
This is pretty awesome:http://techreport.com/review/26523/the-ssd-enduran...

that is really good testbinarycrusader - Monday, June 16, 2014 - link
How exactly is this a no compromise drive when it doesn't offer encryption and it doesn't offer capaciyor-based power loss protection? Data integrity and security seem like pretty big compromises. Or is the SLC buffer seen as a sufficient substitute for a capacitor-based solution?BillyONeal - Monday, June 16, 2014 - link
It is a no compromise drive for the market it targets -- the consumer market. Few / no consumer-targeted drives have capacitors; pretty much all such drives are targeting the server market, such as Intel's SSD DC3700. Very few consumer drives offer TCG Opal, but some do, e.g. Samsung's 840 EVO.binarycrusader - Monday, June 16, 2014 - link
The author specifically mentioned disappointment at the lack of encryption, and the author, unlike you specifically used the phrase "only no compromise high-end SSD in the market" while simultaneously declaring Intel's 730 SSD, OCZ's Vector 150, and Samsung 840 Pro as being in that same "high-end" market. So it seemed rightfully bizarre to simultaneously proclaim it as a "no compromises" drive given the other drives the author also compared it to that are supposedly in the same market.Also, while you're right that few consumer-targeted drives have capacitors, the Crucial M500 does. And honestly, capacitors don't cost that much, but it's no wonder Intel's happy to let all of the other manufacturers fight over "razor-thin" margins.

Because the Extreme Pro is the only high-end SSD without the compromises that the three other SSDs have. Intel SSD 730 and OCZ Vector 150 don't support any form of low-power states and are thus not suitable for laptops. The 840 Pro, on the other hand, lacks IO consistency. All three drives are in the same high-end performance market, thus I'm comparing the Extreme Pro with them.Crucial's drives have capacitors that provide power loss protection but they are the only drives along with Intel's SSD 730. However, you can get away without capacitors if the firmware is designed not to rely too much on the DRAM cache. I would certainly like to see OEMs use capacitors more in consumer-grade drives but on the other hand, I'm not sure if I consider it to be that big of a deal. We don't have a proper way to test power losses, so I don't want to give too much value to a feature that may or may not be needed.
