[Various] 750 Evo Review - Page 7

post #61 of 65
Samsung will never fix the 840 since they have ignored that so far and that is enough reason for me to never get a Samsung SSD again.

The 840 EVO fix was no more a fix than a way to hide the problem they should have foreseen int he first place.

The 750 EVO also uses 256Gbit NAND dies compared to the 128/176? Gbit dies of the past, meaning lower performance. The only reason the performance looks so similar is due to the SLC cache which hides the slower speeds.

For all we know, the lower endurance compared to the 840 EVO/850 EVO may be due to the extra writes it does in order to prevent the read speed issue or simply the lower process node.

There are so many defenders because all their other drives are fine. Look it up. Ask all the people.. and in fact a few years ago Samsung was one of the best choice just because they used their own controller and not the SandForce one.

Like I said earlier: I have 3 Samsung SSDs and would buy Samsung any time again because of my great experience with their drives. Not a single issue.

It is not because of any buyers rumorse.. Their drives are simply good. You don't need to buy any SSD from samsung and thats great. You are able to choose from a variety of great products but please don't act like every samsung drive is a huge failure and people only buy it because it is a big company.


Do you think the same about OCZ? Once their drives were almost the worst ever on the market but toshiba bought them. They are still terrible, right? Right??

I do however let it handle all the OS's reads & writes, then a bunch of apps I have installed on it also. Do you think that could kill an SSD that fast? I'm gonna look into doing what you said you do cause I have a ton of HDD space to use & it makes a lot of sense. It just never occurred to me to offload some the read & write duty from my boot drive TBH. doh.gif

There is the possibility that my CPU's OC was not 100% stable, cause the 1st time it happened I raised my Vcore from 1.32v to 1.33v & it didn't happen again for a few days. Now I have dropped my CPU's OC a good bit on the cache side down to 4.2GHz uncore & am hoping that can help. I had it running 4.5GHz core & uncore, Vcore voltage at 1.32v, & LLC set to high for the last 3 months without issue, it even passed 6 hrs. of XTU's stress test! The thing that really sucks is when it happens the blue smiley error screen goes by so quick I haven't been able to catch the error it spits out, leaving me to grasp at straws as to the cause. I gotta figure out how to dump & read windows errors. That would probably tell me exactly what it is but unfortunately I am not that software savvy yet. Although I do figure it is most likely one of the two reasons I aforementioned, at least they would be the most likely suspects. Although the SSD comes up as all good with CDinfo & HWinfo64 when it's working & it has only disappeared after those 3 crashes? Gonna see what happens with my new settings for my CPU's OC, if the issue persists I'll just go back to stock & see if it still happens then. axesmiley.png

my m.2 transcend 512GB is my primary ... I was new to SSD but I read up on them ... if I didn't do my VMstuff on it ... I bet wear n tear could have stayed near 0% than 1%
so I presume that 1% meant 2.56gb no longer usable

my 850 evo 10TB written so if I added that 1% then that be like 2% wear n tear assuming if i did one drive
both my ssd are over one year old

hmm 6mns ... I checked sandisk n they said >80 TBW ... there should be a sandisk monitor program running in your task tray that keeps track of how much TBW has been written barring any controller issues
or you might have to run it to bring up the monitor program and find the TBW number ... I doubt you wore it out.

When you get the monitor program on your screen they sometimes have a health check program to see how the SSD is doing
if its not doing too well then perhaps you could contact sandisk for warranty RMA

OC should not bother the SSD
I OC my computer at 4.5 Turbo ... I had to cut it down to 4.4 Turbo to be stable

Its looks like it would take years for me to wear n tear my machine

However, I haven't subjected an SSD to heavy heavy SSD activity ... like video editing or databases ... that could age an ssd fast

If your just running apps and playing some games it shouldn't do too much to your drive

Its better to figure its about time for Warranty RMA Return so you have to talk or email sandisk customer support
best to backup your drive so you can restore it to a new drive

I'm not saying that their other drives are all bad or they should be crucified for one minor screw up. The issue is how they treated their customers. I just have two examples of companies who do it right: EVGA and Corsair. They would make things right if it's their fault and won't leave you feel screwed. They recall PSUs even if there is a slight possibility of failure because of factory defect. It means they stand behind their products and value their customers.

Yeah your are right, I've been stable since I backed off the uncore but was tested stable before that also so it is looking like SSD itself is the culprit. I do not do no video editing, setting up VMs, or anything really read or write heavy so I was under the same assumption you said. Just playing games & running apps off of it I expected it to last for a decent while at least. Definitely gonna take your advice & do a back up of my boot drive today then check for the Sandisk monitoring tool to see how much has been written to the drive & what it says about the drives health. If I experience any issues again I'll restore to my 840 EVO & get ahold of Sandisk about a RMA. Thanks for advice thumb.gif it has definitely given me a better idea of what to expect out of most consumer SSDs +rep.
