Samsung SSD 850 vs 850 Pro


Recommended Posts

I want a new SSD 
 
I have 128gb Vertex 4  just now
 
they have come down a lot in price so i want a 250gb one as i run a couple of VM's on my laptop
 
Looking at Samsung 850 Evo
 
but cant see what the difference is between the 850 Evo and the 850 Evo Pro
 
Anyone any ideas?

I too think the warranty is the difference - have 2 850 PRO 256s and 3 EVO 850 250s in my desktop - no diff in benchmarks. IF I were buying another right now, I'd get an EVO.

I have an 850 EVO. Nice drive. Hasn't lost any performance over the past couple of months like I think the 840 did. I think the only real difference between the EVO and Pro is the warrenty. The EVO makes out SATA3 so it can't be any faster. Maybe at IOPS but the EVO is crazy fast anyway I don't think anyone would notice.

Take a look at this. They're both excellent drives. The 850 Pro comes out on top in raw performance so I think it's better to go with that one.

Go with the Pro got one last year to replace my Corsair SSD, looking at picking up another Pro.

The Pro Read speed is 10MB/s faster and is 6GB larger.  Those are the only 2 differences when comparing on the Samsung Site.  Warranty on both is 12 months.

12 Months? The 850 Pro Warranty is 10 years/150TB of writes...

Got this from the samsung site....here is a screen cap (and the link if you don't want to type it out from the screenshot http://www.samsung.com/us/support/owners/product/MZ-7KE256BW ):

 

And here is the full warranty site for that specific drive http://www.samsung.com/us/support/service/warranty/MZ-7KE256BW

which states this at the top:  Warranty Information for MZ-7KE256BW - Parts : 12 months, Labor : 12 months

Well then they have some inconsistencies to work out in the warranty pages.  2 pages state 12 months, one page states 10 years...which is it?

The box itself states 10 year limited warranty (have a box here).  Just went through the warranty paperwork that was included with the drive, it does state 10 years.  

 

So yea they have some conflicting information on their site.  Keep your paperwork, it may be the only thing that can help you.

I have a EVO 850 500GB in my Toshiba laptop and it performs without issue and is fast, fast, fast.  (Beats the horrible Toshiba HDD that it came with).  I have EVO 850 250GB in another older Toshiba laptop (replacing 500GB WD Blue HDD) and it again has no issues and certainly improved performance overall greatly.

just picked up two 850 pros a few weeks back; i heard a few horror stories regarding the evo and a firmware bug which I believe  fix was issued for, but went with the pro instead.

The NAND on the Pro is MLC, higher write endurance.

 

Yeah, but unless you are writing insane amounts of data to it all of the time it's not likely to matter in the real world.

 

the 850 EVO is rated at 75TB of writes (i think the 850 Pro is 150TB of writes) and i think the 840 EVO was roughly 40-45TB of writes and according to write tests online those wrote A LOT more than that (i want to say somewhere around 300TB and was fully functional at that time with no data loss etc) before anything started to act up and went even further before total failure. so if those online tests are a ball park figure on the 840 Evo's those will likely get AT LEAST 150-200TB of writes before you might have potential issues and that was on a 40-45TB rated drive where as the newer 850 evo's are 75TB which i assume the point of failure for those should be noticeably higher so i figure unless i am way off those should be able to easily double that 75TB written figure that Samsung puts on them.

 

so basically on a conservative side of things with the 850 Evo... you could write 40GB of data per day (which i can see anyone sustaining that over a long period of time) and likely get 10+ years out of it as that would still not even hit 150TB of writes which i figure given the endurance ratings of the 840 evo vs 850 evo that if someone where to write data to a 850 Evo til it failed it would likely get noticeably higher than a 840 Evo given different and supposedly better technology in it.

 

bottom line... 850 Evo will easily outlast your PC as you won't kill it from writing data to it to say the least.

 

p.s. i actually got a 850 Evo (250GB) about 2-3 weeks ago (first used it on May 17th 2015 i think) and it works great (i currently have written about 250GB of data to it according to the Samsung Magician software that comes with it and that was over 19 days which comes out to an average of 13.2GB per day and likely will continue to decline as initially in the first few days or so i was around 40GB a day written to it (but it's because i reinstalled windows etc)). i only got SATA II but in the real world, when it comes to general program loading and the like, there is basically no differences between SATA II and SATA III as about the only time there will be a difference is if you were to transfer some files between two of those SSD's. so while SATA II tops out around 280MB/s and the 850 Evo can go faster it's really a non-issue as everything loads up pretty much instantly or with very little delay on my i3-2120 CPU with 8GB of DDR3 RAM. big boost in all around system performance as before i was booting the OS off of a 400GB regular hard drive which boot up time was quite a bit slower and once it did boot it took a while before the system became pretty responsive where as with this 850 Evo Windows boots quick and is immediately responsive after i type in my password on the password screen (where as with the hard drive it would still load for a while) and then can start loading programs as i can load up pretty much whatever i want and ain't much delay there if any. i waited til very recently to get a SSD mostly because SSD capacity/price/reliability was not up to the sweet spot til recently.

 

also, as a general guideline... it's best to keep a portion of the drive free to keep it's performance optimal. i would say don't use more than 200GB of the 250GB capacity and speed will likely remain steadily high. but i won't have to worry as i doubt ill even use half of the drives capacity even if i put on some games.
