Finally some consumer M.2 drives that are unbound from SATA speeds have been revealed at CES: Kingston has launched a 4x PciE SSD - basically an M.2 drive using a Marvell 88SS9293 controller & bolted to a PciE-adapter. 1400MB/s read and 1000MB/s write, capacities of 240GB, 480GB (available soon) and 960GB (Q1-Q2). Samsung has begun volume production of the SM951: 1,600MB/s read, 1,350MB/s write and random performance of 130,000 IOPS read and 85,000 IOPS write in PciE 2.0 - these figures get even more ridiculous with 3.0. Definitely buying one of these and bolting it to an adapter for my desktop. Welmu fucked around with this message at 08:23 on Jan 8, 2015 |

There's 13 results on the first page of Newegg for "m.2", randing from $49 for a 64GB kingston module up to $450 for a $512GB samsung module, what exactly are you looking for? I think M.2 is largely just a different formfactor for msata, which is largely just another formfactof for mPCI-e, you just buy what form you need and plug it in to your laptop/pc. Smaller/cheaper laptops skipped the whole m.2, msata revolution by just soldering on 4GB eMMC modules directly to the motherboard to avoid the cost of the mechanical attachment point + having a human install them.

Most of the M.2 drives you see on Newegg are SATA only, which means they'll only operate at SATA III speeds (6Gbps). The more expensive ones can use PCIe and will be significantly faster. M.2 drives should also have a size in their name like 2242 or 2280. The first two numbers are the width in mm and the second two are the length, so if you're buying one for your laptop make sure it will fit! There's also different keys that can be cut into devices and I think this corresponds to how many PCIe lanes it can use.

Relevant to the M.2 discussion... http://www.engadget.com/2015/01/08/samsung-sm941-pcie-ssd No initial retail availability though. quote:Samsung has started manufacturing a PCIe (M.2) SSD which pulls off a rare trick -- it'll be the fastest drive your laptop has ever seen, while consuming almost no power in standby mode. The new SM951 SSD succeeds the Korean company's XP941, a drive that can already read data at a mind-melting 1.4 gigabytes per second (GB/s) clip. On newer laptops or desktops, its successor will shame that with 2.15GB/s read and 1.55GB/s write speeds (on PCIe Gen 3 tech) using new 10-nanometer MLC flash tech. It also sips 50 percent less power and only consumes a negligible 2 milliwatts in standby mode. The SSDs will come in 128, 256 and 512GB sizes, but only to major laptop and workstation manufacturers to start with.

My understanding is that if you shrink the NAND, you sacrifice some endurance. If that is correct, what kind of endurance can we expect out of that new Samsung drive?

Samsung didn't shrink the NAND for its new drive line. Instead, they've stacked NAND 'wafers' together into a single piece, then stuck that into a single chip. This increases the density without shrinking the process used. Samsung calls this 3D V-NAND, but plenty of other companies are doing the same thing without bothering with fancy branding. Provided the company is reliable, you can look at the endurance numbers quoted for any drive as a good measure of longevity, without worrying about the actual tech used in the flash memory itself.

You say that, but the post immediately above his says "10-nanometer MLC". Not exactly the 3D-VNAND on an older process. I know why you posted this, because it's the first thing I thought, too, so I had to slow down and read the previous post. Now then, the question is, why isn't it using some 30nm class 3D-VNAND?

The SSD I use for all my games and programs is running out of space (Samsung 830 Pro 256gb) and I need to get a larger drive. Should I get the Samsung 850 EVO 500gb? And if so, the easiest way to transfer my data over would be to image it with something like Macrium Reflect and then just restore that image onto the new SSD?

Sure, but do you really need the extra performance over the 840 EVO? It's quite a big difference in price. Also you can just use the Samsung migration software.

I'm sure there was some discussion on this earlier and I wasn't really paying attention, but can someone put this in perspective a bit: I have now around 530 power on hours on my SSD and I'm seeing ~570GB of total host writes. I'm sure that isn't incredibly excessive, but when I start thinking about it as 1GB+ per hour, it sounds like a lot. Is it?

Even if you do that constantly, it's 26 GB per day, or 1 write cycle of a 240 GB SSD per 9-10 days. That's less than 40 full writes per year before write amplification, and your drive can probably take ~3000 full writes (75 years at 26 GB/day). The NAND in your drive will last as long as you need it to.

And yeah, I know 'holographic storage' already exists to some extent (though not in ~cube~ form, and it's WORM storage), but if we're still using physical media of any type around the turn of the century it'd be sublimely depressing.

Newegg has the Evo 850 250GB (MZ-75E250B/AM) for $132.99 shipped is this the thing where Samsung is trying to push out competition from the market by flooding the market with cheap 250GB rotational drives were $60 new this time last year, $49 refurbished, I am seeing them new for $45 this year and $25 refurb. Does Western Digital even make an SSD? Or have they accepted a long and slow death? Newegg had a 5TB external drive last week for $125 which is crazy cheap but by next year it's going to be hard to even think about a large capacity rotational drive when Samsung is offering a 10 year warranty on their consumer drives and they're 6x faster.

The best deal right now is WD Blue 1tb disks which go on sale for $50, while smaller disks will not be very much cheaper. Crucial's been pushing the SSD prices down a lot more than Samsung (samsung's drives are typically a little more expensive but still competitive price wise). The amazing deals on Samsung disks tend to be sell-offs on the older models.

Samsung also has several cost advantages over many firms, since pretty much everything is done in-house including fabrication. Fab itself is a cost advantage - Samsung is buildings its NAND on an old, cheap 40nm process yet achieving densities comparable to 19nm NAND thanks to its planar 3D NAND geometry.

That is not how V-NAND works. V-NAND refers to a 3D memory array printed onto a single silicon chip, not multiple chips glued together. Also I'm pretty sure Samsung is still the only shipping V-NAND supplier. You might be confused by the fact that it's very common for even 2D planar NAND flash to use multi-chip packages where several chips are stacked up and encapsulated inside a single package (the black plastic piece visible on SSD circuit boards). In a sense, this is 3-D, but it's not the same thing. V-NAND is a legit new technology, not a mere branding exercise.

If the 951 is a PCIe version of the 850 Pro, just as the 941 was the PCIe version of the 840 Pro, it's not 10nm planar but instead V-NAND with a ~40nm dimension on the cells and really great endurance.

Everything has been defaulting to partition alignment at sector 2048 (1 MiB) for a while (Windows, Linux, etc). However, the SD Association wants partitions to start at sector 8192 (4 MiB). Then there is stuff like this: quote:Most modern partitioning tools align at least the first partition on a multiple of 2048 sectors by default because this works well for most modern disks; however, some SSDs require still larger values, such as 4096 or even 8192. I've been partitioning all my drives at 2048, but every time I load a pre-made image (like loading Raspbian) it wipes the card and re-creates the partition at 8192. Would it be beneficial to start doing partition alignments at sector 8192 going forward?

Friends don't let friends buy Crucial drives, am replacing my M500 with a Samsung 840 EVO because the M500 does this in my home server. Had to learn how to reboot Linux without using reboot or shutdown today.code:On the positive side, the 840 EVO came with the firmware that fixes the performance issue, so that saved me some time setting things up.

The SSD has just over 1TB of host writes after 3 or so months in use, and yet there's a write amplification of almost 7x on it:  Googling returns a thread on Intel's forums with a bunch of people having the same issue and no solution or cause offered.

I don't really play a lot of games that benefit noticeably from super-fast load times, and as you can imagine I'm feeling a bit wary about loading 30-40 gigs of extra stuff on there with the amount of shuffling my data around it seems to be doing.
