Samsung 840 EVO 1TB Question

Hey guys,

So I bought a Samsung SSD 840 EVO 1 TB about a year ago. I have done a lot with the drive gaming wise especially modifying games which a lot of the times required fresh installs. I've also had to reinstall the OS a few times. I was very new to the SSD scene but yesterday decided to check my Samsung Magician. So far everything checks out but I have written a total of 16 TB so far according to the Magician.

My question is does anyone know how many TB total that the SSD can take? I feel bad that I wasn't more aware of how SSDs work. I've already moved my games that I have modded and continue to do so onto a secondary hard drive to prevent any further uneeded writing to the SSD.

 

Hi, I also bought a 1 TB 840 Evo.
All you need to know is here http://www.anandtech.com/show/7173/...w-120gb-250gb-500gb-750gb-1tb-models-tested/3

So even if you write 100 GiB with write amplification =1, you will still get around 30 years. It took you 1 year to write 16 TB = roughly 44 GB/day so you will get around 60 years with that. My calculation is very rough but basically dont worry about it

 

Oh OK awesome! I was worried. I was thinking about going out and buying a new 850 EVO but the extra 500 in my pocket is the better outcome here. Seems like I'd of wasted my money over nothing. I shoukd get more life out of it now too since my writes per day have decreased dramatically. Thanks again!

 

Yeah, the nand life expectancy is not an issue with almost any modern drive in most normal workflows.

But the bigger issue with TLC drives (the original Samsung 840 and the 840 EVO and possibly, too soon to tell, the 850 EVO...) is that the drives degrade in READING old data (older than about 1 or 2 months) that the drive has written and not modified since.

Note that even after the fix that Samsung supplied a few months ago, the issue still persist for some EVO and 840 (original) owners.

My recommendation would be to avoid TLC drives at all costs (new or old models). Especially Samsung's examples, but other manufactures may be affected as well (but just haven't shown up as being problematic, yet).

 

Would the Pro series be TLC or just the origid all and EVO series?

 

Both 840 Pro and 850 Pro use MLC
Both 840 Evo and 850 Evo use TLC

840 Series use 19nm/21nm NAND
850 Series use 40nm V-NAND

 

It may be a Samsung issue, period. Look in the big thread of the two links I posted and a few pages back, someone is suggesting the 850 Pro is not as fast as it should be.

 

TLC is junk whichever way and Samdung has really screwed the pooch with 840Evo... I'm surprised that OP hasn't noticed any slowdown with it yet.. I would be more worried about that then the TLC memory wearing out..

 

Nope, Do your own benchmarks, moving your power from Balanced to High Performance and vice versa will cause differences, I have had Samsung 470 and Samsung 840 EVO both work great, I never noticed any slow down at all on the EVO, when I did the fix, my iops went up, no real difference could be discerned. Samsung SSD's are good quality(probably have the least problems), since you got 1TB model, you got the most of everything, enjoy, your laptop will go obsolete long before the SSD kicks the bucket if it ever does.

The 470 warranty of 3 yrs has expired by a year or two and still is just as fast as was when it was new. My Evo has a few more years on it.
