Endurance Experiment Writes One Petabyte To Six Consumer SSDs

Emetophobe Re:media wearout indicator (MWI)? (164 comments)

If you read the article (I know this is Slashdot) they explain that MWI is an Intel-only SMART attribute. They use different SMART attributes for the Kingston and Samsung drives.


This SMART attribute starts at 100 and decreases as the NAND's rated write tolerance is exhausted. It's completely unaffected by the number of reallocated sectors, and it's been ticking down steadily since the experiment began. The remaining life estimate in Intel's SSD Toolbox utility is based on the MWI, and so is the general health assessment offered by HD Sentinel, the third-party tool we've been using to grab raw SMART data.


On the HyperX 3K, the SSD life left attribute tracks flash wear. Like Intel's media wearout indicator, it counts down from 100 and is tied directly to the rated lifespan of the NAND.


The wear-leveling count is sort of like the MWI and life-left attributes on the Intel and Kingston SSDs. It's "directly related to [the] lifetime of the SSD," according to Samsung, and it bottomed out after 300TB of writes.

Endurance Experiment Writes One Petabyte To Six Consumer SSDs

Emetophobe Re:How is 700TB "endurance"? (164 comments)

1TB of writes per day to an SSD probably isn't a normal usage scenario for your average consumer. Samsung for example claims that the average consumer writes no more than 10GB/day to an SSD:

The 840 Series demonstrates impressive lifespan results under industry-standard methods of simulating real-world use-cases. BAPCo's SYSMARK, a third party benchmarking tool, shows a 20 year lifespan under a moderate workload consisting of 35% random writes. Applying JEDEC's testing methodology, the minimum lifespan is 7 years, despite an extremely severe workload containing 75% random writes. Keep in mind that these testing scenarios, especially the JEDEC workload, are used primarily for enterprise computing applications (e.g. workstations, servers). Under consumer workloads (internally estimated not to exceed 10GB/day for most users) and more appropriate testing scenarios, the 840 Series will show considerably better endurance numbers.

$3000 GeForce GTX TITAN Z Tested, Less Performance Than $1500 R9 295X2

Emetophobe Re:So glad it's over (151 comments)

You're correct. Newer Intel CPUs can use a technology called Intel Quick Sync to speed up streaming and video encoding. Basically it uses the hardware encoder on Intel CPUs to perform the encoding.

Streaming software like OBS supports Quick Sync. Impact on CPU and GPU usage is much lower since it's using the iGPU (which would normally be disabled when playing games with a discrete video card). It's basically using silicon which would otherwise go to waste, since most people disable the integrated video on Intel CPUs. Here's a guide that explains how to setup Quick Sync with OBS, and it shows that CPU usage goes from 50-75% with a x264 encoder to 1-5% with Quick Sync.

AMD and NVIDIA Trade Allegations, Denials Over Shady Tactics

Emetophobe Re:NVidia's sin (69 comments)

You're partially correct. AMD cards tend to draw more power and run hotter. You're wrong in thinking AMD cards are slower though.

The R9 280x is comparable in performance to a GTX 770, but the 770 costs as much as an R9 290.
The R9 290 is up to 40% faster than a GTX 770 but they cost the same.
The R9 290 is also slightly faster than a GTX 780, but the 290 is $100-150 cheaper.

Basically Nvidia cards are overpriced and need to come down to match the price/performance of AMD cards.

Titanfall Dev Claims Xbox One Doesn't Need DX12 To Improve Performance

That BS. Microsoft and Sony fanboys mocked the Wii for targeting 720p. According to them they had all the games in glorious 1080p while Wii peasant didn't had real HD.

Correction: The Wii was 480p, not 720p.

It's hardly a phablet compared to your Nexus 4, it's only 4mm longer...

Nexus 4 dimensions: 133.90 x 68.70 x 9.10 mm (with a 4.7" screen)
Nexus 5 dimensions: 137.84 x 69.17 x 8.59 mm (with a 4.9" screen)

GTA V Makes $800 Million In 24 Hours

Emetophobe Re:Gah-bage! (396 comments)

I want them to continue developing Half Life ! And I miss the simulation games of yore - Age of Empires, Civilization, Roller Coaster Tycoon, etc..

Age of Empires was an RTS, not a Simulation game.

I'd much prefer something challenging and stimulating than a boring game cloned from 15 years ago because they haven't bothered to come up with anything new and just want to jazz it up with eye-candy, give it a new name, and sell if for $60...

Geez, make up your mind. First you say you want more sequels to a bunch of 10-20 year old games, and then the next paragraph you say you don't want rehashed versions of 15 year old games. Which one is it?

The last time I used a dial-up modem was...

Emetophobe Early cable (410 comments)

When I first "signed on" around 1995 dialup prices were around $30-40/month for a 28.8 connection. Within a few years there were so many competiting dialup providers that you could get a 56K connection for $5/month and it came with a personal website, several emails, usenet access, etc... You could literally find a hundred competiting ISPs in the yellow pages in the Toronto area.

I was one of the first to get cable internet in my area. I can't remember the price, but it was fairly decent, and the service quality was amazing. I remember being blown away by the speeds. I'd usually get 600KBytes/sec down from sites like sunsite.unc.edu. A few years later my isp (Shaw) and another isp (Rogers) decided to swap customers for some odd reason (without any say from the customers of course). So I ended up getting stuck with Rogers, and service quality quickly degraded over the next several years. The dialup ISPs slowly died off and competition died with it.

Fast forward 10-15 years and I'm still with Rogers. The service quality is much better than it was 5 years ago, mostly due to the CTRC finally getting off their asses and slapping Rogers over their throttling practices. The speeds are good, I get 6.5MB/sec on average and I almost never have any service outages (maybe once or twice a year for a few hours). The price and caps are unacceptable though. I pay $80/month for 50Mbit down with a 150GB monthly cap. What I wouldn't do for a little competition again. I had it with dialup, why can't I have it with cable? I should still have access to dozens of competiting providers like I did ~20 years ago. /rant

The Man Who Convinced Us We Needed Vitamin Supplements

Emetophobe Re:Diet and laziness (707 comments)

While I agree with some of what you said, there are medical cases where supplements are neccessary. I had a severe Vitamin D deficiency 2 years ago that ended up causing osteomalacia-like symptoms (severe muscle, joint, and bone pain throughout my entire body). My family doctor ran blood tests and told me I had the worst Vitamin D deficiency that she had ever seen in 35 years (I had something like 12 nmol/L of 25-hydroxyvitamin D). Anyway, long story short, she perscribed me 1000mg of Vitamin D once a day and the problem went away within a month or two.

Facebook's Android App Can Now Retrieve Data About What Apps You Use

Emetophobe Re:Pause while in call (176 comments)

I thought you could already do that without requiring READ_PHONE_STATE? When your app loses focus (for whatever reason, a call, user switches to another app, etc..) then onPause() gets called. You should be able to handle losing focus there... without needing any special permissions.

Though I only write android apps as a hobby, so maybe I'm wrong.

Firefox 20 Arrives With Per-Window Private Browsing, New Download Manager

Emetophobe Re:So what did they take away now? (181 comments)

Looked at the location bar... shed a tear for my "http://"

You can disable that by going to about:config and setting browser.urlbar.trimURLs to false.

It's old, but still a pain. Remember when Stop had a separate button?

There's always been a separate stop button, you just have to customize the toolbar so that the stop button is ordered before the reload button, otherwise it "combines" them into a single reload/stop button. http://forums.mozillazine.org/viewtopic.php?f=38&t=2142587

Basically you right click the toolbar, select customize, then drag the stop button to the left of the reload button, and viola... separate buttons (yes it's retarded).

Andy Rubin Steps Down As Chief of Google Android

Emetophobe Re:Quit, landscape, MTP, Linux, root (156 comments)

Using the home button does not end the app, it's still running in the background using memory. I think OP might have meant "exit" to mean an easy way to exit the app that also 'force stops' it. A feature most apps do not do and one that I would welcome, since it's an unwanted set of taps (settings / apps / force stop).

Why would you want apps to be force closed? Just so you don't see them in the recent apps list? There's a good reason for Android to only pause apps and not close them:

1. When an app is no longer needed it gets paused (it still uses memory, but it's in a stopped state, unless it has background threads or services).

1.a When that app is started again it is resumed from its previous state (much faster than having to restart the app from scratch since it's still in memory).

1.b If Android needs to free up memory it may close the paused app, in which cause the app needs to be restarted from scratch the next time it's run (since it's no longer in memory).

That behaviour is well designed in my opinion, it uses available memory to speed up apps, and Android only frees memory when it needs to. The developer activity lifecycle illustrates it pretty well.
You should never have to use Settings->Apps->Force Stop unless you're dealing with misbehaving or badly designed apps.
