  1. I'm surprised that this is not faster than the majority of the competition. Perhaps as you note, that is because of the SSD 960 series being so strong. I wonder if the PCIe x8 version would be slightly faster. They say 6000 MB/s sequential read and 1,000,000 IOPs random read, so it is certainly possible. No improvements on the write speed though. I would love to see a SSD someday overtake the PCIe 3.0 x8 limits though (that Samsung isn't too far on the sequential though) - we may someday need a PCIe 3.0 x16 SSD! It is also likely that this is a TLC drive. All of Samsung's other "PM" drives are TLC, while the "SM" drivers are MLC. Still the PE cycles at 40nm 3D should more than adequate. Maybe an MLC drive would do better - both in endurance and performance. The difference should be comparable to the 960 Evo to Pro I'd guess, provided they both have the same percentage of overprovisioning. Overall, I'd say the Huawei ES3600P V3 and the HHHL ES3600C V3 are the top SSDs.
  2. Now that helium hard drives have been on the market for a couple of years, would you consider them to be as reliable as existing "conventional" hard drives, more reliable, or less reliable? Will the helium inside eventually leak out?
  3. It looks like they already have one. The Samsung SM961 (MLC version) and PM961 (TLC version): http://www.anandtech.com/show/10168/samsung-shows-off-sm961-and-pm961-ssds-oem-drives-get-a-boost The Anandtech article mentions that both have the Polaris controller; not sure if it is the same one as before. Here's a review too: http://www.tomshardware.com/reviews/samsung-sm961-ssd,4608.html For sale 512 GB SM961: https://www.amazon.com/Samsung-Genuine-Eluktronics-Eluktro-MZVKW512HMJP-00000/dp/B01N2IRIDV/ref=sr_1_2?s=pc&ie=UTF8&qid=1482178679&sr=1-2&keywords=sm961 1TB PM961 https://www.amazon.com/Samsung-Genuine-Eluktronics-Eluktro-MZVLW1T0HMLH-00000/dp/B01MSO0S39/ref=sr_1_9?s=pc&ie=UTF8&qid=1482178679&sr=1-9&keywords=sm961 Let me know what you think. There are probably reviews of the PM961 somewhere on the web.
  4. Is this leaderboard worthy? It does seem to be overall, an improvement over the last generation. Any word on if there will be enterprise versions? The SM951 for example had the SM953, which was an enterprise variant with power loss protection. There are typically enterprise versions, like the 850 Pro having the Samsung SV843 and Samsung SM863.
  5. At this rate, we are going to need PCIe 3.0 x8 slots soon enough for SSDs - either that or a PCIe 4.0 x4 motherboard pretty quickly. Any idea what the 4k QD1 read/write will be? That is what really matters for most end consumers versus sequential.
  6. Maybe they will counter with a larger SSD 750 Evo. That seems like a logical approach. But yeah, I see your point. At the low end, margins are razor thin and competition will be fierce. I just hope that this someday translates into better prices for higher end MLC SSDs.
  7. The SSD 850 Evo more or less ran circles around the MX300 performance-wise. It will come down to price I guess. Still, it's nice that affordable 2TB (or about 2TB) HDDs are coming to market. I guess it's street price that matters.
  8. The weak 4k performance on this SSD makes it a questionable choice, seeing that 4k is the main type of workload for consumer use. Apparently this drive is also very energy efficient, which is may make it compelling for laptop use though. Just curious, are there any consumer drives with Toshiba's 48 layer 3D NAND BICs? https://www.toshiba.co.jp/about/press/2015_03/pr2601.htm?fromRSS=IR2015032601
  9. Are these all TLC NAND products or is Samsung also planning to release a 64 high 40nm MLC NAND?
  10. Basically an SSD for people who need capacity, but don't care about speed. Depending on how it's priced I guess it might have a chance. The 850 Evo 1 TB seems to be the closest thing this has to a competitor and it is a faster performing drive overall.
  11. Well, we can settle, so to speak. This image is impressive: QD1 Performance of 3D XPoint I guess the real world performance was never going to be as good as advertised - 1000x. It's not a replacement for DRAM for sure. I wonder how many P/E cycles 3D XPoint/Quant X can take? Especially compared to an MLC 3D NAND SSD at 40nm today? It's advertised to be a lot better than NAND, but Micron only advertises 25 DWPD. http://www.tomshardware.co.uk/intel-micron-3d-xpoint-memory,news-53632.html I'm surprised at that one. A 40nm MLC 3D NAND SSD with 28% overprovisioning can do 10 DWPD. A hypothetical 40 nm SLC 3D NAND with 28% overprovisioning could probably do 25 DWPD easily. The real question is, what is the real world endurance of 3D XPoint or is the 25 DWPD just ultra conservative?
  12. I stand corrected then. Hmm ... are there any differences between this and the Memblaze Pblaze 4? The only I can see is that the Pblaze 4 uses 15nm Toshiba Toggle NAND. I would assume the firmware is different? That would explain the performance differences? They will probably offer a full height 6.4 TB version as well I would guess. There was one on the PBlaze 4.
  13. Apparently Micron can make a very fast SSD if it chooses to - something that we don't seem to see very often in its consumer based SATA SSDs.
  14. The performance is certainly behind the competition, but I guess it's a decent bargain. The Samsung SSD 850 Pro is about 50% more in terms of cost per GB. I'd assume up to 2TB will be released.
  15. Another tech demo of Optane: https://www.youtube.com/watch?v=gMJCA2ZWfk0 Article: http://www.pcper.com/news/Storage/IDF-Shenzhen-Intel-Demos-3D-XPoint-Optane-File-Copy-2-GBs It's really the random IO performance that is impressive.
