Corsair Neutron XT (240GB, 480GB & 960GB) SSD Review: Phison S10 Debuts
by Kristian Vättö on November 17, 2014 9:00 AM ESTPower Consumption
Currently the S10 controller doesn't support slumber or DevSleep power modes, which is why the idle power consumption turns out to be high compared to the competition. Phison told me that the slumber power (HIPM+DIPM) implementation is nearly complete and a new firmware should follow in about a month, but in the meantime the S10 and Neutron XT aren't really suitable for mobile use. The load power consumption is more moderate, although there are more efficient drives and controller solutions on the market.

At this point, we have a better chance of finding Loch Ness Monster than getting sf3700 :)eddieobscurant - Monday, November 17, 2014 - link

Any endurance testing done?I have a Neutron 512GB (not GTX) and am pretty disppointed at what the wear leveling indicator from SMART data is telling me..... it looks like the 512GB Neutron has an expected write endurance of only 100TB?

I haven't done any endurance testing, but Corsair is rating the Neutron XT at 124TB (according to The Tech Report). Note that the SMART data isn't usually an indication of an expected failure as the threshold has been set by the manufacturer for warranty reasons, so they can determine whether you've exceeded the endurance rating. In that light 100TB is pretty good because most drives are rated at around 70TB or so.Joepublic2 - Monday, November 17, 2014 - link
I'm disappointed to see them dropping the 5 year warranty on the Neutron line. I bought a Neutron and a Neutron GTX for myself and a few dozen for various clients primarily due to the 5 year warranty. Expected endurance figures mean nothing to me as a user if the company isn't willing to back it up with a appropriate warranty.Kristian Vättö - Tuesday, November 18, 2014 - link
Actually, there was an error in the reviewer's guide, so the warranty is indeed 5 years similar to the original Neutron series. I've updated the article as well.glugglug - Sunday, November 23, 2014 - link
That is very reassuring.One other disturbing thing is the raw read error rate reported in SMART. It starts out looking good after a cold boot, then gradually drops to a value of "1" as the system gets a higher uptime. I think this is actually calculated wrong, being a direct mapping from the raw value, which is always identical to the "Soft ECC Correction Rate" raw value (sitting at ~250,000 after about a month of uptime), instead of being calculated based on the rate of change in that raw value like its supposed to be. Corsair SSD Toolbox labels that counter as "informational only", while CrystalDiskInfo, Stablebit Scanner, & other tools complain when the nominal value crosses the apparent manufacturer suggested threshold of "6" after a week or so.
Restarting Windows does NOT reset the counter -- it gets reset only by a cold boot.

That wear leveling indicator has very little to do with ACTUAL flash lifetime. It is mostly to do with giving the manufacturer the ability to determine when warranty has expired.sonicmerlin - Monday, November 17, 2014 - link
It's really kinda cool these things have quad core processors now.On a side note, does anyone know when someone other than Samsung is going to release 3D NAND?

IMFT (i.e. Micron and Intel) is next year and so is SK Hynix. Toshiba/SanDisk is H1'16.
