I didnt know MSI has this kind of warranty. Do they also send you a new one and you can mail them the faulty one all for free?

They better have low RMA rates, otherwise with the thin margins as they have they would be bankrupt in no time 😛

No, I'm sorry, I meant they use a serial based warranty, meaning you don't need to show proof of purchase.
 
Uhm.. is the 840 Evo still a good option or much worse then 850 or Crucial MX100

I read somewhere that the 840 Evo uses a "cheaper" memory type that only allow 1000 rewrites.. is this the same with the 850 and how does the Crucial MX100 compare in this respect??

Yet HP uses Intel Sanforce drives exclusively. Probably Dell also.

Not Dell also... they use, perhaps among others, Lite-On SSDs with the Marvell controller.

Dell and probably HP uses whatever is available and cost-effective, rather than any specific type drive.



Because HP is such a synonym for reliability

You won't find anything HP in my house... :colbert:

Hp makes good network switches and laser printers 🙂

I vote the MX100, I have a 512GB one and it's been solid, it replaced a Crucial C300 256GB ssd I'd had since launch and other than more space and a bit better seq. performance I don't really notice any difference.

From what I saw of all the BSOD issues, the problem occurred if you used Acronis to clone your existing drive to the MX100.

I don't recall anyone using fresh installs or other methods having issues.

I "cloned" from an acronis backup to MX100. No issues. Working since almost 1 year.

EDIT:

And to add to that I came from an intel xm25 G2 80 GB. And honestly, I don't feel a speed difference at all. So go with the cheaper one of those and if price is the same if would buy Crucial. My parents have m4s running and no issues as well.

I think I'm going to grab two of the 256GB MX100's to replace my 240GB Corsair Force 3 and my Intel 320 120GB. I was leaning towards the 850 EVO, but I'm not sure if it's worth the $10 premium?
 
Since I got burned with the 840 EVO performance degradation my next SSD will be a crucial.

I hope they can fix the issue for good though.

In all fairness, Samaung has a fix for the slowness issue. Of course they can't make everyone apply it.

Not sure which fix you talk about, but the one they released couple months ago apparently isn't a permanent fix.. today on anandtech news they will release a new "fix" in march or something like that

are the 850 Evo's also affected by this btw??

Yep they had one temporary fix to hold users over to a more permanent one. I suppose you could argue that the issue shouldn't have made it to production, but at least they are trying.

I have not seen anyone report that the 850 is having performance degradation issues.

But the fix you referred to in the first place, did that help with stale data or not?
 
I don't want to spread FUD because Samsung probably paid attention to avoid this issue in the newer SSDs since it's quite dangerous marketing-wise unless they're stupid, but the problem is that the issue sprung up like one year later. Plenty of other brands have sold SSDs with issues, this is relatively minor IF they can get it solved for good.

As I understand it, it did with some but not others. Luck of the draw...

I don't believe the 850Evo is seeing this problem.

850 evo is still using some kind of tlc memory which seems to be the drives affected.. there more expensive pro's have mlc which don't have this prob..

nobody has the 850 evo or maybe it's not around long enough but i expect the same problems

No, EVO is using a completly differend kind of memory. While it has 3 bits per cell, its using 3D NAND, built at 40nm class fab. That means much much bigger cells and thus lower possibility for that kind of leakage.

Problem with 840evo is small cells (19nm) and triple level cells. That means its much more sensitive to cell leakage, as it needs to differentiate more voltage states.

First, to avoid confusion, the problem I'm talking about is Samsung TLC drives suffering from perfromance degradation with "stale" data, click here to read

I know the 850 Evo uses 3D NAND but it is still TLC kind of 3D NAND (as opposed to MLC 3D NAND on 850 Pro)..

Can you explain why the performance degradation prob with stale data couldn't also happen on the 850 EVO given it is still TLC type memory?

3D NAND stacks on less space, but there still seems to be the TLC vs MLC distinction so I'm not sure

... Well, that explains a lot. I know what I'm doing when Windows 10 comes around! :/ I'm almost glad that my clone attempt failed on my desktop now, though I use my laptop more...
 
Isn't the main downside with the MX100 that it uses quite a bit of energy, so heating up more then the Samsungs.. meaning your laptop fan will spin up more?

Still would like to know if 850 Evo with 3D NAND TLC mem won't have the same degradation probs as 840

When idle it uses more, when being used it consumes less. Both consume at a third of the power of a standard HDD.

I think this page is pretty good at putting things in perspective:

850 evo is indeed 3D NAND, but it is still the TLC kind (as opposed to the pro with MLC).. doesn't that mean the performance degradation of stale data problem which plagues the 840 Evo's can still affect the 850 evo.. because of the memory still being TLC ?
