Wow. Now that's what you can call the next generation of storage.
Are there any others coming out soon or are Samsung far ahead of the competition?
It's really amazing that there's no Intel desktop that can run PCI Gen4 at the moment.
Will be interesting to see how stock will be. Especially if this is also one of the few SSDs certified to run in a PS5. Which has an M.2 slot.

- Ygg2 6y agoLooking at 4k random reads at queue depth 1, Samsung is superior. But worse on writes. I'd go with faster reads, since that impacts load times. The 7GB/s is meaningless unless what your disk does is move huge files around.
- barrkel 6y agoOr if you're running an analytics database, where table scans are the norm.
- Ygg2 6y agoOk, but on the other hand DB could be write heavy. It depends on use case. In future SeqQD32 could be way more important if things like DirectStorage utilize it better.
- dragontamer 6y ago5.5 GBps is needed to be an effective PS5 M.2 drive. PCIe 3.0 caps at 4GBps.
- smolder 6y agoPS5 uses a custom 12 lane flash controller, not an m.2 drive. I think they optimized for things other than peak bandwidth, too, like latency from disk to VRAM and random read. (And hardware lossy compression!)
- dragontamer 6y agohttps://www.gamesradar.com/ps5-ssd/ https://www.gamesradar.com/ps5-ssd/ PS5's custom SSD will be 5.5 GBps. But it supports M.2 expansion. > "We will be supporting certain M2 SSDs," Cerny confirmed. "These are internal drives that you can get on the open market and install in a bay on the PS5. They connect through the custom IO unit just like our SSD does, so they can take full advantage of the decompression, IO co-processors, and all the other features I was talking about. Here's the catch though: that commercial drive has to be at least as fast as ours. Games that rely on the speed of our SSD need to work flawlessly with any M2 drive." ------- PCIe 4.0 is a very flexible and high-bandwidth protocol. GPUs have been doing PCIe -> GPU transfers for some time (without any intervention of CPU or DDR4 RAM). Its good to hear that the PS5 is fully taking advantage of these capabilities. But it does mean that M.2 drives of a certain speed are needed to effectively play PS5 games, should you use the M.2 expansion port.
- smolder 6y agoMy mistake, haven't been keeping up. Thanks for the correction and info.
- hmottestad 6y agoAre these the ones that Anandtech has commented use a modified controller instead of new controller? So scaling to PCIe 4.0 is using a lot more power than it should.
- driverdan 6y agoSamsung isn't "that far" ahead of the competition. They've been behind. PCIe gen4 drives have been out for most if not of all 2020. The 980 Pro is faster than the competition but the others will have drives this fast out soon too.
- leetcrew 6y agoany particular reason why you say that? I haven't looked into the gen4 drives, but looking at the anandtech storage bench, their gen3 drives are enjoying a comfortable lead over the competition. the 970 evo plus matches or exceeds the transfer rate of its competitors in most tests, and has significantly better performance consistency when the drive gets full. the only problem is that the additional performance is not always worth the additional price per GB.
- throwaway8941 6y ago>the additional performance is not always worth the additional price per GB There are factors besides performance. Samsung is not known for particularly high quality firmware (the 830 Evo performance fuck-up, multiple queued TRIM bugs, etc.), but after reading a disproportionate amount of horror stories of silent data corruption and data loss for most of their competition, I'd rather spend the extra bucks.
- leetcrew 6y agowhat I mean is, the typical consumer will probably never notice the performance difference between a 970 evo plus (or even 970 pro) versus any other middle-of-the-pack nvme drive. I personally went with the evo plus because I expect the drive to spend its life mostly full and I'm using it to compile c++ projects from. the extra $50 was worth the most consistent performance to me. as for reliability, this is hard to judge from anecdotes on the internet. you really need access to something like the backblaze data to start drawing conclusions. I had an oem samsung drive die in my xps 13 a week after the one year warranty expired. I have a WD hard drive that's still going strong after eight years. unless you have a lot of data, I think it's best to just back everything up, accept that you're rolling the dice, and hit a $/perf point that's acceptable to you.
- gameswithgo 6y agoThe thing to remember is that most people's workloads do not tend to improve much from a slow but decent SSD to a fast SSD. Workloads just aren't often large and sequential enough. You can find lots of benchmarks of actual things on youtube/google, and things like boot times, game/app load times etc barely change. For people who do need fast, large sequential operations, I'm sure it is amazing though.
- loeg 6y agoThere's still a nice jump from SATA SSD to NVMe SSD (doesn't have to be top of the line NVMe).
- ChuckNorris89 6y agoDepends. Many cheap NVMe drives that ship with budget laptops are actually slower than good SATA SSDs like Samsung 850. The high speed bus interface is useless if your flash and controller are garbage to the point where NVMe is sometimes no indication of a laptop's storage performance and just a marketing name.
- loeg 6y agoThis thread is discussing only "decent" and better SSDs. Yes, I'm sure you can find absolute garbage with an NVMe interface.
- ChuckNorris89 6y agoEven "decent" brands make garbage NVMe drives for the budget segment to which most consumers are oblivious because they assume NVMe > SATA.
- loeg 6y agoTo clarify: For the purposes of my earlier comment, "decent" applies to individual models; not a brand's entire product line.
- Ygg2 6y agoWatching the space I wouldn't call this next gen storage. Well. The storage is OK but the way most systems work there is no perceptible difference between an NVM m.2 drive and Sata for most regular use cases (i.e. everyday use, not server or a simulation rig). This might change in future with stuff like DirectStorage. The truly "next gen" performance was Intel's Optane 3D XPoint, but that is ludicrously expensive. And even then it's like boot from SSD 12 seconds at $130 dollars vs Optane 10 seconds at $1200.
- gameswithgo 6y agoThe most important difference between m.2 and sata is two less cables cluttering up your pc =)
- throwaway8941 6y agoAnd the much higher temperatures (if your M.2 is an NVMe). Could anyone knowledgeable explain why NVMe tend to get much hotter than SATA under similar conditions? I've been testing mine with not more than 400-500 MB/s and it quickly gets to 60°C+, while the old 840 Evo doesn't get above ~45°C (running a very similar synthetic workload). I would've guessed the opposite: the fully enclosed SATA drive should get much hotter.
- jeffbee 6y agoWhy do you care? The critical temperature on a retail 970 Pro is, IIRC, 84C, and is almost impossible to hit.
- throwaway8941 6y agoMostly out of curiosity. Higher temperatures also put additional stress on flash memory, and I tend to run my hardware into the ground (I'm still using a 50GB Intel SSD from 2010), so there's that.
- Ygg2 6y agoI'm not sure if I count, but I suspect two things. Heat dissipation and controller complexity. NVMe controller might be more computationally heavy and so they might emit more heat*. But assuming that NVMe and SATA SSD controllers emit the same energy, it makes more sense that NVMe would be hotter. Think about it. If you throw a ball of high heat meat would it cool faster if it was connected to a large body of water (SSD with its chasis) or a small body of water (NVMe small piece of plastic that is the NVMe)? Another thing to check if your NVMe either has proper thermal pads placement and/or if the air from the front coolers is reaching it.
- dragontamer 6y ago> Are there any others coming out soon or are Samsung far ahead of the competition? There have been a number of PCIe 4.0 drives coming out so far. * Gigabyte AORUS (5GBps read) * XPG Gammix S50 Lite (5GBps read, lowest power consumption for laptops) Both seem pretty close to the 5.5GBps PS5 speed, and probably would work. 7GBps sequential is the fastest SSD I've seen so far, though QD1 IOPS is more important to the typical user.
- fomine3 6y agoAll of current consumer Gen4 drives are just rebadged Phison E16 drives.
- altmind 6y agoTiger Lake mobile cpus have pcie 4. There are already some reviews for these laptops.
