Question about the 850 pro vs 850 evo.

[GeorgeJedson]

The 850 evo is 105$
the 850 pro is 140$

I read that the evo had some firmware issues. Im not sure exactly if someone could clarify or if this has been fixed. I know of the 5 vs 10 year warranty difference. And I've seen little difference in speed from benchmarks.
Could someone clarify all this for me and tell me some info on the issues of the evo or if it is worth it to stick with an evo.

Evo's are just fine, the firmware has been fixed as far as I have understood especially in the recent variations. The major difference is the warranties, capacities, and speeds.

I would not hesitate to buy an Evo.

Reliability on the EVO is slightly less due to the use of TLC nand vs MLC nand on the pro. Not that it matters outside maybe the server field, the reliability on both is through the stratosphere.

Thanks a lot sir.

Get the EVO. The FW issues were with the 840, NOT the 850. Reliability is NOT a concern as mentioned above... TLC/MLC/SLC.. whatevs.

I heard somewhere that the Evo's write speeds will slow down once it fills up some sort of buffer. Google says this is called "Turbo Write". Pulled from a review of the 840 Evo on storagereview.com, it's explained like so.

This performance delta is largely achieved by implementing Turbo Write which is always-on and utilizes the NAND packages to create a buffer up to 12GB in size to which data is first written before later being transferred to the SSD when there is idle time. The buffer varies by capacity at 3GB for 120 and 250GB, 6GB at 500GB, 9GB at 750GB and 12GB at the top-tier 1TB model.

If you manage to fill up this write buffer (which is unlikely for most desktop consumers), you'll likely see write performance drop significantly with the Evo. If I'm not mistaken, the Pro does not have this disadvantage and can sustain its write speeds.

The pro is for heavy use and rewrites like video editing where your constantly deleting and encoding.
