For those of you with M.2 PCIe slots on motherboards (or laptops like Lenovo Carbon X1 or new Dell XPS) - this is the top-end SSD for this year to get - if you can afford it.

Read/Write: up to 2,500 MB/s and 1,500 MB/s (PCIe 3 x4 lanes).

This is retail - unlike the SM951 or older XP941 so Magician works, should get firmware updates as well as AZ/Samsung support.

This is pre-order - but AZ usually ships in less. "Usually dispatched within 1 to 3 months."

Note 1: This requires a PCIe M.2 slot - not SATA M.2. Older laptops/motherboards may support just SATA.

Note 2: Not all boards/laptops can boot NVMe; many BIOSes have been updated to support NVMe boot and driver support exists in current Windows versions 10/8.x with driver for 7.

Note 3: If you don't have an M.2 slot you can still use a PCIe to M.2 adapter e.g. "2Port M.2 NGFF B+M Key SSD to PCI-E PCI Express 4X 4 Lane Converter Card Adapter" from the 'bay for £7 quid - or there are slightly more expensive versions.

But - you may not be able to boot from it.

Now that's a badass read/write speed. I'm planning on upgrading my PC soon so something like this will be on the list of compoents. I guess any new, moderately good m/b will support this. I'd better check that I guess.

Absolutely - check NVMe support and how many PCIe lanes are/can be assigned to M.2 slot depending on what else is plugged in. I have a X99 with the much older XP941 and even there the lanes are at a premium...
thanks! right, time to put my research hat on me thinks

This thing is expensive for sure - but if you were to get a PCIe SSD what are the choices?

- Kingston HyperX Predator AHCI 480GB - ~£334 and less performance (1400/1000 R/W)
- Samsung SM951 AHCI 512GB - ~£250 but OEM and AHCI
- Samsung SM951 NVMe 512GB - ~£265 but OEM and slightly more expensive

The older PCIe SSDs are not cheap enough to make it worth it:
- Samsung XP941 AHCI 512GB - ~£260 but OEM, AHCI, less performance and various issues
- Plextor M6e AHCI 512GB - ~£312 more expensive, less performance

PCIe SSD prices have come down within a year but not a lot of movement these days. You can certainly wait for Black Friday deals later on which should be the time this ships anyway
people who don't understand what this is voting it cold. Only just available today so Amazon will have stock soon.
hot, Read/Write: up to 2,500 MB/s and 1,500 MB/s (PCIe 3 x4 lanes). thats insane speeds. Wish my MB supported this upgrade.
cold voters do not understand the product!
Nice but I wait till NVMe is more mainstream as its a high price, still new tech and not everything can boot from them.

It's more likely that people DO understand what it is, but are asking themselves "why would I want to spend that much money for a relatively small increase in operating speed?"
my X99 Motherboard has a card for using these but I feel it's too overpriced and not necessary for home use.
It's absolutely pointless unless you're working mainly of your C drive for a living.

The 850 Pro is stonking quick and probably boots faster than the pcie equivalents, considerably cheaper too.

It's worth buying a 1tb SSD than these new m.2 drives, at least for another generation.

You can partition it dont need to have a giant C drive? Only time I advocated single partition is BitLocker with some SED SSDs which blow additional partitions away...

If you only use sub 512GB what would be the point of a giant drive? Sure you want some overprovisioning but if most is empty I'd rather have a faster ssd. At these sizes you no longer get higher read/write bw or i/o from larger sizes. If you think you're gonna need more space sure but if not?

I have 2 much older XP941 and they perform great for me certainly better than any SATA ssd i have though not have a Pro 850... This should be a lot faster.

The price is not hot as you can get the sm951 ahci for 70 or 80 for the nvme.
Better having a small boot drive and a large hdd as storage . I run the sm951 nvme with magician and have no issues. I would wait till prices drop or get sm951 which would work out cheaper.
To be honest in the real world an 850 pro ssd with magician feels nearly as fast as the sm951 as RAM caching helps system performance considerably.
If booting quick is very important then seek a MB with ultra boot like asrock. That would help more than a pci-e ssd alone.

You are comparing the prices of the 128GB SM951 version - it also has lower performance than the larger sizes.

For 512GB I don't see SM951 being cheaper - especially NVMe plus as I said it's OEM - so not support or firmware updates - I am genuinely surprised Magician supports it.

Not everyone uses a SSD just a fast boot - some may need data accelerated too on a SSD; what's the point of the app starting fast if you wait minutes for data to load off a HDD?

Memory caching helps everything including HDDs, then not have a SSD at all or just get a Kingston V300 it's much cheaper? It probably performs similarly if the memory cache does all the work

I think in all honesty it would cheaper to use a large ssd instead of 950 pro if you have large data sets.
512GB is not that large and a 850 pro would suffice and be considerably more cost effective. The warranty with sm951 is 3 years with flexram and in real world I can't tell it apart from my 850 pro.
For most of us a smaller boot drive ssd with Large hdd is fine.

A healthy dollop of personal anecdotal subjective opinion culminating in a strong absolute final condemnation that contains no reference to any fact whatsoever. All the while, the person giving that OPINION is completely ignorant to the errors of their ways and thinks they've been extremely fair and judicious and can't possibly contemplate the idea that they are basically Fox news with a pulse.

I'm of the OPINION that this is not such a HOT deal. It's a great drive no question and some may find it useful but as I've pointed out there are other ways to achieve this. If you need facts go storagereview or anandtech as I don't have time to ref sm951 vs 950(since it's just hit market ). You will see the FACTS there and can decide for yourself and maybe buy one.

I'm not sure we understand each other here: sure there are always cheaper options but by that token why get a sm951 or 850 pro at all? Any decent ssd will do for much less with good performance.

If you just want fast boot then why a 128gb sm951 at all? Why not 32 or 64gb sata ssd? Probably boots not a lot slower.

My point is this is for people with app+datasets within 512gb but want top performance, especially on laptops/workstations. For those people it is good value as sm951 is not cheaper and xp941 used to cost 400.

If your dataset is larger then get something else that fits. If you only need fast access for a small dataset but need to carry lots of data infrequently acessed then by all means get a fast ssd + something else. It all depends what you need.

Also to mention this is a SED so you can encrypt it with full performance with BitLocker or similar (hardware AES). Other PCIe SSDs did not have crypto engines so we had to either use SATA SED SSDs or software encryption with XP941.

Or just use the built-in Windows hybrid-shutdown feature and boot up in 10 seconds with a HDD. Things like this and SSD's included benefit much more than just bootup times.

But then again, based on those tests there is an insignificant delta between the 850 Pro and EVO - so why would anyone pay more for Pro?

If you don't have a significant I/O load then nothing past a "decent" SSD makes a big difference.

I guess we have to re-arch the whole storage stack for such high bandwidth/IO of PCIe SSDs - but that likely won't happen while HDDs are still around. Massively parallel IO of tasks which can be sustained by them are still scalar, etc, etc.

One silly example: OS updates are downloaded sequentially and then applied; they could easily be pipelined to be downloaded/installed/cleaned in parallel - if not multiple downloads/installs simultaneously. But on a new install you wait hours for downloads then updates sequentially - when in parallel modern SSD systems would likely achieve it much faster...
Price increased to £282 on Amazon now. These aren't for everyone, but those who do lots of intensive disk io will see a benefit. In a few years time as more laptops and motherboards come supplied with a suitable slot and BIOS these will become more mainstream and prices will drop accordingly

I wonder what consumer applications significantly gain from a fast PCIe SSD? Maybe editing 4K video! It is CPU/GPU bound but due to the size of the files fast disk access my well help too.

In many cases probably because of the hype and the word Pro in the name!
The Pro range for Samsung has had significant differences in the past with regard to the NAND used, the endurance rating and the warranty terms so add to that the synthetic benchmarks and it can be a seductive package. Good value! Not really but some people just like to buy high end stuff regardless.
For the 840 Pro you had the benefit of not having the dodgy TLC NAND of the 840/840 EVO. But that’s says more about the poor quality of the vanilla 840s than the value of the 840 Pro.

Any kind of video editing in a proper software application and not one that is limited coded to avoid the bottlenecks of slow hard drives etc. You won't need to be editing 4K video to notice massive differences. Editing video is not CPU intensive, it is bandwidth intensive. Rendering the output is CPU intensive and has no benefit from fast storage, different things.

Incremental backups is another thing that can benefit as well as updating any archive (zip/rar/etc)

I highly doubt your view of people buying these because of hype and word "Pro" in the name. Can't imagine many people at all even knowing about them who would be in that box.

True but for typical home users the benefits in these areas in terms of time saved are relatively insignificant versus the extra cost. In other words it’s a luxury item that doesn’t offer good value.

We were talking about the 850 Pro and its predecessors as the PCIe drives are still quite exotic I sense.
