Quite horrible but its a storage drive after all



Pro 512GB version.

Bug is causing extremely low speeds when reading old data.

PS: Still using hard drives and loving every second of it.

Use hard drives all you want, I've saved years in loading and start up time. Love hard drives for mass storage but ssd for boot and games everyday!!

The title for this is a bit misleading. Its not degradation as such... Its just how the Toggle NAND works, as to why old data gets such low speeds only Samsung could answer that.

I don't boot up and as for gaming SSDs hardly help at all and in most cases not at all.

I looked for this topic to see if it was posted and didn't find it.  Mods take it down.

LOL SSDs hahahahaha

It's good practice to shut your PC down every so often and not merely rely on sleep. Having been using an SSD for just over a month now the difference is phenomenal.

SSDs hardly help at all......uh yeah sure ok. This guy ^

Until you use ssd for a boot drive or gaming dont comment cause you have no experience with it.

[GoodBytes]

Well, I knew TLC nand wasn't a good idea. But at least a fix is underway.

So, I guess the temporary fix, is to defrag your SSD, once and while.

This should shift data everywhere and rectify the problem until a fix is available.

Obviously you don't know what you are talking about.  Again for gaming it hardly helps at all and as for a boot drive I know what it does for boot times but like I said I don't need a faster boot time.  Geezus.

Even if I shut my pcs off I would not buy an SSD to have faster boot times.  Also I have no reason to shut off my pcs I am not paying for the electric bill.

Do you have an ssd at all in your system? If you dont then you have no idea if how fast ssds are. At all.

Yeah you do, or the memory leaks from your browser will fill up your RaM and kill your HDD faster. Shutting down and rebooting is good for your performance.

Also, it helps a lot with games. Load screens practically disappear except for online ones where you need other player data.

I also find general OS responsiveness goes up plus no annoying clicking sound under my bed when my rig is doing F@H overnight

Ah yes hard drives are dropping dead all over the place from what you said.  Uh ... no ...

As for loading screens whatever man.

Hard drives meh, I swapped my WD10EZRX for a 840 evo 1TB because it was so noisy. My 840 evo has the same performance bug but I don't really care about performance for a storage drive.

I'm glad you love every second of it, because there are so many

I had so many that I started calling them minutes.

What a waste of power. I could never do that. At least help out the person who is paying the bills (however small a difference it may make).

For the record I almost never have the lights on and I don't leave the tv on when I am not using it.  I do understand trying to limit costs in regards to power use and such.  Also until recently I had power saving features on for all my pcs.

Related to burning thru resources/something to consider:

The "average" home in the US:

#1 Juicer = A/C and Heating

#2 Lighting (it's pooled, but 2012 "avg. home=60ish lightbulbs)

Then washer-dryer, fridge and all those 2x 2000W "pewter" rated PSUs.

Anyway, it took me a little less then 1 year to switch every damned CFL/Incandescent bulb in my place over to the newer (2nd/3rd gen) LED bulbs. 65w equiv. floods were the most expensive (30-35$ each) 60w 2700k incandescent equivalents=15-18$.

Expensive right? Well...

I about flipped my lid when I saw the y/y electric bill difference. Despite 'ol lectric raising rates by 5-8%/KWh mid year, according to the bill total electricity use was down by 33%. I used to carry the bill in my wallet to nudge ppl into considering a "switch". Oh yeah, for those unfamiliar with the good LED Bulbs: I'll be dead by the time the bulbs burn out, if the numbers are genuine. Cool to touch+you can drop one from 6' onto concrete and the thing will just bounce. Newer models are filled with silicon goo...and others, the heavy duty ones are in a container, hermetically zipped, stopping any transfer of heat, saving A/C $$.

I was never a green type but I am familiar with commodities, the finite ones which are war-causal. Not appropriate to go into falsified USGS data and related things, but hey, look at Gazprom...and Qatar and...etc etc.

$£€1000 well spent. Plus, no lingering guilt re: 10x 5000PSU (rated Clay).

If you're on a fixed tariff, it won't make a difference. However if you're not, it does.

100 watts per hour (as a rough number for a mid-spec pc) x 8 hours of inactivity (user sleeping) = 800Wh per day = roughly 300KWh yearly.

Over here electricity is roughly €0.25 per KWh, meaning I'd be wasting around €0.20 per day or € 75 each year for leaving it on at night.

Then there's also the extra wear on the PC components and the carbon footprint from producing so much electricity which is then wasted. You may think that won't matter because it's only a little bit, but if a million people do it, it's not just a little bit anymore.

If you really are going to leave the PC on overnight, at least let it do something useful. Plenty of science facilities have applications that you can install to allow them to use your PC's computing power for their scientific research. At least that way it's helping to cure some disease or something similarly interesting when you're not using it. If you're not worried about the electricity bill anyway, the extra electricity needed to power a core or two won't make a difference after all.

What kind of computer uses 100W while sleeping? Hell, what does that while idle? Does an average PC even use that much from web browsing!?

This is going to be *REALLY* bad if the datacenter TLC drives they have experience the same issues. I'm getting about 40-50 megabytes per second transfers on a three month old file on my 1TB EVO and about 400-500 on a 15 day old set of files.
