OS Drive 850 vs 840 Question

[haste.]

Hello all,

I bought a 500gb 850 evo last week (let's just say I made the decision at 2am) and am currently using an 500gb 840 evo as my boot drive. My question is would there be any value to migrating the 840 to the 850? Will I see a measurable performance increase or will the 840 prevent the 850 from operating at peak performance?

My intuition says plug the 850 in and go on with my day, but I'm not certain enough without asking the community.

Thanks!

Measurable in benchmarks, maybe. Noticeable in use, no. I updated my wifes computer from a 128 GB 840 evo to a 250 GB 850 evo. Could tell no performance difference. I personally consider the 850 Evo more reliable because of the problems the 840 had.

From doing a little research on Windows 10, it sounds like I can clean install on the 850 with no problems and no key. Thinking I might offload any programs I have installed on the 840 to a different drive, format, and install on the 850 for the reliability.

I just pulled an 840 EVO from 2 years of service and noticed no reliability issues whatsoever in that time.

I would be very wary of the 840 evo drives after that whole performance degradation issue. You can read more about that here. The issue is that performance degrades for any data that has been on the drive for a while. Data that was written recently is okay. So basically, people would put drives in their system, it would run great, benchmark great, etc. Then months later it would be slow as shit. Samsung's fix or "optimization" for this problem was to release a tool that essentially re-wrote all the data on the drive; a kludge if there ever was one, and one that will obviously have a negative impact on the limited write cycles that the drive has.

They have released a fix via a firmware update, but I remain skeptical since I don't really believe that a firmware update can fix an underlying flaw in the flash technology used. I would guess that the firmware update does something along the lines of re-writing stale data at some sort of established interval, which is still not ideal compared to other SSDs as it would be eating through a lot of write cycles even when the drive isn't doing anything. Personally, I would switch to the 850 evo and sell that 840 evo as fast as I could.

Just to be clear, the problem never effected reliability, only performance.

this. i got this and this. and now i get 900mb write and 1900mb read. all for less than $300.
