Conclusion, Pricing, and Final Thoughts
Conclusion:
PROS:
- Class leading write performance per capacity and even better read performance.
- TLC write speeds at a given capacity are comparable with competition's MLC offerings (thanks to VNAND).
- High endurance rating and warranty for a TLC product.
CONS:
- The 3GB TurboWrite Cache of the 120GB and 250GB models may be a bit limiting for power users.
Pricing and Availability:
850 EVO mSATA:
- 120GB – $80 ($0.67/gb) (Amazon)
- 250GB – $130 ($0.52/gb) (Amazon)
- 500GB – $230 ($0.46/gb) (Amazon)
- 1TB – $450 ($0.45/gb) (Amazon)
850 EVO M.2 SATA:
Decent launch MSRP's with availability of all lines and capacities on launch morning. Precisely how it should be done.
Warranty:
The Samsung 850 EVO line carries a 5 year warranty, rated at 40GB/day for 120GB/250GB (75 TBW) and 80GB/day for 500GB/1TB (150 TBW).
Final Thoughts:
Samsung has come along with yet another great product launch, and those wishing they could get an 850 EVO into their mobile platforms no longer need to wait. You are getting the same high performing VNAND driven by the same proven Samsung SATA controller – just in a different physical packaging. TurboWrite, Samsung Magician and RAPID all apply to these products just as they did for the 2.5" variants. Despite some changes to flash package counts, performance of these new units remained consistent if not identical when compared with the 2.5" EVOs. The only fault I see with these new smaller mSATA and M.2 SATA form factor 850 EVOs is that they did not launch sooner.
High end performance and endurance combined with TLC pricing. These are my default recommendation for mSATA and M.2 SATA applications.
Hi Allyn great review as
Hi Allyn great review as always.On his review Kristian at anandtech experienced 50 seconds pauses during high IO workloads on the 1TB mSATA model.Have you noticed anything simila?
We noted no such abnormality
We noted no such abnormality in our testing. To double check, I just fired up the 1TB mSATA sample, running the same 4k random QD32 workload as Anandtech. I'm 1500 seconds in and IOPS has not so much as hiccuped.
Thanks for the quick

My X99-Deluxe really wants a PCI-E 2x M.2 SSD in it.
If you want a PCI-E M.2 SSD
If you want a PCI-E M.2 SSD then get a Samsung Xp 941 ssd, it is currently one of the fastest PCI-E ssd on market.
I cant get the 500gb m.2.
I cant get the 500gb m.2. drive to work on my asus x99 pro 🙁 a lot of the asus x99 series have problems with the drive

Excellent review of these new
Excellent review of these new drives Allyn!
Does anyone have links to real world performance testing on the current round of consumer SSDs? The synthetic benchmarks clearly are useful for showing differences between SSDs for IO intensive workloads, but many consumers just care about boot times and game/program loading speeds. I just upgraded to a 256 GB Crucial MX100. It would be interesting to see what real world difference the high performance consumer SSDs actually bring.
Once going to a modern SSD
Once going to a modern SSD (like the MX100 you have there), you get a large gain in performance, but the gains within the high end don't show very much difference as far as boot times / random reads go. Note how tight the pack is on a pure read workload like the Iometer Web Server test – very little difference between models there.
The difference then lies in tasks that lean on the current limits. A large set of writes to your 256GB MX100 will hit the ~300 MB/sec limit, and be ~50% faster at that same task on an SSD that more easily saturates writes over SATA.
It's really going to take better interface (PCIe NVMe) and faster flash (3D NAND) to see the next big leaps in performance, but even then we will see diminishing returns on something like a boot time, as those start finding other limits like CPU and even RAM speed once the SSD speeds are opened up.

What a timely promo for
What a timely promo for Samsung, hey everyone look at this shiny new stuff while we drag the 840evo carcass out back and bury it in a shallow grave, hoping we forget about the fact that 840evo customers are up the creek without a paddle.
Not sure why anyone would buy a Samsung SSD after the 840evo issues, the bodged “fix” & the absent March “fix”. I’ll be returning mine for a refund & steering clear of Samsung at least in the short to medium term. This community needs to send the message that customers should not be treated in this way.

Yea its sad how little
Yea its sad how little coverage the 840/840 EVO issue have had lately. The media is simply letting Samsung walk away free and clear.
I had also hopes some one sued Samsung by now just tog give them some bad PR.
I had enough with Samsung support, retailers refusing RMA because Samsung sees its not covered and simply decides to ignore laws in respective country’s.
I’m still waiting for a PcPer pod cast with a fallow up on the Samsung TLC issue on the 840 and 840 EVO because Samsung needs more flack because there behavior is not acceptable and should be punished.
Also reviewers should add Samsungs bad warranty and support practices to the Cons on any Samsung SSD review since its a real issue for consumers if and when there product experiences a malfunction.
To me good insurances from the manufacturers is more important then speed and cost of the product since a problematic SSD is the worst thing that can happen for the consumer and when the manufacturers refuses to fix or replace the drives or just send out another effected drive as a replacement and just stick there heads in the sand pretending all is fine.
Almost all SSD’s are fast enough to day that reliability is realy the key concern amongst all but the most hardcore enthusiasts.
Samsung have shown there support, warranty and service has little to no value for the consumer when theres a wide spread issue.
This is 850 series review,
This is 850 series review, nothing to do with your off topic comments about VERY DIFERENT 840 series. Next time try to use right forum.
Will there be a 1tb m.2
Will there be a 1tb m.2 version?
Yes, Samsung clearly said
Yes, Samsung clearly said that they are working on it (can’t find the link now). Probably half a year away.
