I don't think anyone has access to a controller to know for realsies.

quote:The Intel 600p only switches into a read-only mode when the spare area is exhausted. Intel also noted users can copy the data from a read-only SSD by installing it as a secondary drive in another computer. Intel provided an official response outlining the recovery procedure, and we include a more detailed explanation in the link. Assuming this is actually what happens, bravo Intel. You simply cannot use a SSD with no spare NAND. I'd happily buy one.

"The Optane SSD was able to achieve 7.2x times more IOPS at low queue depth and upto 5.21 times the IOPs of conventional SSDs at high queue depths. Optane SSDs also provide 8.11x times lower latency than conventional NAND solutions. An Optane Technology based SSD has 10x times the density of conventional SSD drives. The marketing material also claims it is 1000x faster than the competition available on the market but it isn’t clear to what exactly they are referring to. Optane SSDs will have 1000x the endurance – which, if true, should mean the device has virtually unlimited life span for practical purposes."

I swear it doesn't feel like I am waiting for the SSD anymore. It feels more like Windows 10 has inefficiencies that cause delays rather than waiting for a HD to load. Also the task manager says my Intel 750 tends to be around %50 or less usage regardless of what I am doing.

I'm not sure what to think about all of it. In the past, there were huge QA teams and dedicated beta tests. Latter don't necessarily imply being better than the insider preview stuff in terms of reach, but at least there were proper communication channels. Now there's just this lovely nearly useless Feedback app. I've been sending constant feedback with that app. A bunch of my feedbacks have definitely been fixed. Probably a coincidence.

Totally agree about no return path for communication, nor a bug tracking thing of any kind. Pretty pathetic overall. I feel like I should be getting really familiar with Linux because Windows might be jumping the shark.

From googling a bit, you might actually want to RMA that drive. You could also keep backups and keep running the drive. Some say it could be a cable/data issue, one time kind of thing. Others say it could be the beginning of the drive outright failing.

Ika posted:Does the 960 EVO also have throttling issues? I just installed one in my work PC, and tried backing up a 40gb database file I had copied to it earlier, and by the time the file had finished copying the average speed had dropped to 400MB / s. This is using win7 with the samsung NVM driver but without magician. That is normal. 40GB is enough writes to make the drive perform at its lowest speed since the cache is full.

quote:The DC P4800X purportedly offers up to 30 DWPD (Drive Writes Per Day) of endurance, which measures how many times you can fill the drive per day over the warranty period. 30 DWPD is unheard of for NAND-based SSDs; the most endurant modern SSDs top out at 10 DWPD. The DWPD metric can be muddy due to differing capacities, but overall, the DC P4800X can absorb up to 12.3PB of data during its service life. Intel's 450GB DC P3520 SSD, which is NAND-based, can withstand only 590TB, so apparently, 3D XPoint offers almost 21x more endurance than NAND. Hot sex. Still, not 1000x greater endurance than NAND like the hype said way back when.

I know SSD technology has continue to mature over the years, anyone have any sense if there's much life left on that M4? I know I've seen 10+ year endurance lifetimes kicked around for newer gear, any more definitive answers on the older stuff? Run something like Crystal Disk Info and look at the Wear Level Indicator metric. It counts down from 100 to 0 and supposedly around 10 is where the drive should start telling Windows it is bad. http://crystalmark.info/software/CrystalDiskInfo/index-e.html

lordfrikk posted:Is steady-state something that every drive will reach eventually (I guess like some kind of burn in) or does it require long enough uninterrupted usage after which it will return to "normal" (non-steady-state?)? I'm trying to understand if tests using speeds reached in steady-state are of any consequence for regular consumer workload. Steady state occurs when a drive has burned through its buffers and has to directly write and read to the NAND. Consumer models can sustain high levels for shorter amounts of time and are tuned for bursts of i/o whereas enterprise drives are tuned to provide better performance while in steady-state. Benchmarks tend to hit worst-case scenereos so this means more i/o than the buffers can take and then you get to see steady-state performance. On a consumer machine you will probably never reach a steady-state.

da anime bulldog posted:So, im building a computer for gaming, and I'm getting back into the swing of learning what all this poo poo means as I select parts. I'm going to go with a Samsung SSD. NVMe is a faster protocol and was created to work with NAND flash storage. It is far more efficient at using solid state memory than the SATA protocol and does really good when hit with a ton of concurrent requests. So, you definitely want NVMe if your stuff has support for it.
