Is there any reason to purchase 860 Evo @$129 when the 660p is $95?

The 860 evo is better. What you pay is what you get.

I would buy the XPG 8200 Pro over either.


The Intel drive is pretty good at reads but the Samsung drive is better at writes especially large ones.

Not really.

The main difference between the two are the NAND chips used. The Evo uses 3-layer or 'triple layer' TLC while the 660p uses Quad layer QLC - Both lifespans are about the same but the samsung is a bit faster.

it really depends what you want to do with the drive. if you just want to put games on it. the 660p will do fine.

QLC lifespan is considerably lower.
660p write speeds will tank horribly once you exhaust its write cache (10% of free space, if I remember correctly).

860 EVO is a SATA drive even if M.2 form factor. This means read-write speeds are capped at 520-550MB/s.
660p is an NVMe drive, its maximum speeds, at least for reads and writes in short bursts can be considerably higher.

660p is a great disk for an OS Drive with some standard applications on top. (128GB or so)

860 is a great disk for large chunks of data, and working with them.

The relative price unfortunately is completely countering those use cases :)
Chances of a noticeable (and annoying) difference in performance or durability are likely to be low, though lifespan is one reason for me to pay a little extra. You really do get what you pay for in that sense, and storage for most is about reliability. That is why its a great OS drive. Lots and lots of reads, small bits and bobs, you're not writing a drive's worth of stuff on there daily - perfect for QLC.

I completely disagree. Until we get some real data on how long QLC drives last, I would use one as a data drive rather than system drive. System drive usually implies a more constant and larger read-write load.

System drive implies you don't store critical data on it. That was my approach for that. I'll leave the endurance testing to others...

Components die, anyway, that 860 will too, so I doubt there is a real financial advantage long term.

Thanks for the lively discussion. This will be used as the only drive, with diligent backup.

Would certainly opt for the 860 personally. Part of that is our very limited (collective) experience with QLC. If/when/how it fails etc. You will do a lot of read/write on a single disk for a system, often multiple tasks together, so the speed remaining consistent is also useful.

The Intel 1660P is an academic choice vs any SSD. Even though it uses QLC NAND it has a 5 year warranty. Where the 1660P shines though is in gaming. There is no issue using the 1660P as a boot drive. Samsung does have good utility programs but Intel has about 4 downloads that you can do to improve the speed and longevity of the 1660P. In some cases it is just as fast as the 760P. I have also noticed that it is more consistent at downloads than my Adata SX8200.

This is kind of an apples to oranges comparison. We are comparing SATA TLC to NVMe QLC. My two cents, Samsung drives are insanely reliable. The 860 EVO is no exception. or me personally, I value my data too much to trust it to QLC especially as a boot device. In your case, the sole internal storage device for the machine. If you were just gonna throw some games on it, why not. If I must choose between the two, it's the 860 EVO. You will more than likely barely notice any difference in speed anyway.

A 5 year warranty is great but if it is the only drive in your PC, a warranty does not boot your machine for a couple of weeks while you do the RMA.

For SSDs what you primarily care about when it comes to warranty is TBW (terabytes of writes):
- 660p spec says 200TBW for 1TB model and 400TBW for 2TB model.
- 860EVO spec says 600TBW for 1TB model and 1200TBW for 2GB model.

The flash in 860EVO has been tested and shown to exceed that spec by considerable margin.

660p is not bad by any measure but we simply do not know how that Flash lasts.
When I look at writes in my 3 drives, it currently amounts to around 25TB in a year and my usage isn't very write-heavy.

"the 860 Evo series is powered by 64-layer V-NAND technology . (V-NAND stands for vertical NAND, which contains flash cells stacked vertically and 3 dimensionally for greater density and speed" .

I value my data too much to trust it to QLC especially as a boot device

It is interesting that a few years ago people were saying the same thing about SSDs vs HDDs. The product has been around


A 5 year warranty is great but if it is the only drive in your PC, a warranty does not boot your machine for a couple of weeks while you do the RMA.
Should I add then that it is from Intel? A company that is just as good in reliability as Samsung and has some serious credit in the NVME protocol. Even SSDs will die at some point.

Is there any reason to purchase 860 Evo @$129 when the 660p is $95?
Between these two 660p is a no-brainer. You get nearly triple sequential speeds and more than adequate random R/W for less money. 860 Evo is just an overpriced SATA drive with less than impressive by modern standards specs. Tales of Samsung reliability are just that - tales. I've had just as many dead/defective EVOs as any other brand (except older phison-based Kingston and OCZ SSDs).
Plus with 660p you get 5 year warranty, which means Intel is quite sure that their QLC drives won't die before TBW and MTBF is reached. Samsung only gives 3 years on their QVO series and 5 years on Evo/Pro.

That is an interesting statement considering that the Intel 660P 1TB is actually selling cheaper than 1 TB SSDs.



The Intel 760P 1TB is the hghest SPEC NVME drive you can buy and 1TB is $249.99


vs the WD Balck which is $309.99




At the end of the day the Intel 660P will feel faster than an SSD and just as fast as other NVME drives. In fact if you read reviews on the 660P you will see it is faster than the 760P in some tests. For me there is no longer any reason to get an SSD over an NVME drive. Intel is good at making more than CPUs. I will give you a few examples.

1. 1GBit NIC. Most Intel solutions are better than anything Realtek has
2. Optane: This is hands down the fastest storage you can buy. It is expensive but it works.
3. Thunderbolt

You realise the the 660p is an SSD as well as being NVMe right. They're not mutually exclusive...

Yes I do realize that the main difference between an NVME and SSD is the interface. I was highlighting that an NVME drive is typically more expensive than a traditional SSD of the same capacity, unless you are talking about the 660P. That is the reason I would get that instead of an SSD. I actually have 2 of them in RAID 0 and they fly. I ordered a 3rd for even more throughput. As I stated before they do come with programs and utilities that will improve the performance and longevity of the drive.

I would go with the intel 660p, cheaper and has a better 4k random read. Check here

Sustained 4kB Random Read
Average of QD1, QD2 & QD4 Data Rates in MB/s - Higher is Better

Intel 660p 125.4

samsung 860 evo 70.5

The laptop it's going in has a m.2 data see now(256gb), just wanting some more room. The Its a high end business latitude i7-7820HQ (4c/8t), w 32gb 2400 ram. It's pretty fast/quick as it is, I don't do many large file transfers, <1gb between laptop and servers. The 860 would not be slow at that at all, but it I can get nvme for $35 less at the 1TB size, kind of silly not too. As usual everyone has given much to ponder.

Trust me with the firmware update and Rapid storage program for the 660P but mostly price. There is an argument for the 660P being the best value in storage for any platform. I rememebr when traditional SSDs were first launched there was the argument about durability when we went from SLC to MLC. Now the argument is about QLC but I can tell you the Intel is faster, in every regard than my Sandisk Ultra 2 960GB and my Micron 11002TB SSD.

Between these two 660p is a no-brainer. You get nearly triple sequential speeds and more than adequate random R/W for less money.
Provided that the drive is near-empty. Reviews and test results show heavy reliance on SLC cache size of which depends on free space. Once the drive is full 660p speeds will drop well below average SATA drive speeds.
Yes I do realize that the main difference between an NVME and SSD is the interface.
SSD is a type of drive.
NVMe and SATA are two most common drive/SSD interfaces on desktop today.
Form factor is a different thing on top of that - 2.5" and M.2 are the most common ones and while 2.5" usually has SATA interface, M.2 has both SATA and NVMe.

660p is a banging value drive but only thanks to its caching implementation.So 2tb is a great buy, 1tb not so much,512 GB is straight awful.
Get wd blue 3d.
