Samsung 850 EVO M.2 and mSATA SSD review





In this review we test the new M.2. and mSATA models of the Samsung 850 EVO Series SSDs. Seriously nice storage technology as they are hyper fast, yet made to be very competitive in pricing. Armed with truckloads of performance and that attractive pricing, Samsung will shock and awe you...

Great review!...
I'll be making the SSD plunge soon, and for the first time, and it will be my boot drive. I'm going to go with a 250GB+ size initially now that pricing is approaching a threshold that I can live with, but I had a couple of quick questions that some kind soul might condescend to help me with...
*How are these drives formatted, and what about cluster sizes? I'm guessing that as with platter drives, that < 4k, NTFS cluster sizes, while more efficiently using disk space would also add disproportionately to the overhead of the drive and tend to lower performance, but I'm not clear on that, actually.
*What about paging files? I can't see how maintaining a page file on the SSD could be anything except beneficial, but I just thought I'd ask...
*What is it about the Samsung EVO SSDs that makes them so popular? I've noticed that the 840 is listed as Amazon's best-selling SSD. Just curious.
*Would you recommend an 850 over an 840?
Thanks!
In terms of formatting, I've always left it at default settings. 850 Evo better than 840 Evo - they're just cheap for the high performance you get. If you've got 8GB or definitely with 16GB of RAM then you can delete the page file, run without a page file - saves SSD space & can increase performance a little. If you keep pagefile definitely leave it on the SSD, don't put it on a platter hard drive!
EDIT: 840 Evo suffers from read speed degredation of old data, but that's probably gonna be fixed by a firmware release next week - should sort out the 840 Evo drive in my laptop! Yeah, so don't get the 840 Evo.

Answers my questions. The 850 is priced just fine, actually, so there's no reason not to go with that, really. I read about the firmware update for the 840's that corrects the problem you mentioned--but, yes, I'll just stick with the 850...! Thanks again for the response...

fortunate one
I found a Samsung Evo Pro 1tb ssd Model # MZ-75E1T0B/AM in the garbage dumpster a few months back. It was un-boxed and at the very bottom of the dumpster. At first I thought it was a cheapo calculator or e-address book as they are so incredibly light, hells not much more than a credit card...well ok a bit more, after I got home I discovered it was a SSD. Knowing the price of these gems I figured it was probably a display model or broken defective. so I plugged it into my laptop and to my astonishment and joy it fired right up! I downloaded Samsung's magician software and updated the evo's firmware. The beauty runs just like I had paid the full $650.00 + that the very same store who tossed it out is asking for a boxed and wrapped NIB SSD.
I have made returns to this dumpster and have gotten some other great finds. Although nothing as fantastic as the Evo I wouldnt have been able to experience the benefits of a SSD had it not been a blessing and gift from the Gods.. Yes indeed ladies and gentlemen Samsung Evo's ROCK!
Peace

Wow! Nice review HH
Looks like one of those is a 'must have' for my up-coming Skylake build.

I'm getting same performance from my 850 Evo as in this review. Destroys my HyperX 3k which is kinda crappy drive.
