I have a side question, I'm trying to see if this would be a valid solution. But, I do need your opinion. I recently started testing out ramdisks which is like a drive on ram, the reason for this is for speed since ram is faster than nvme. I tested it out on my computer using Linux and I only have seen a few GB/s of transfer to ramdisk to ramdisk. I was wondering do you know why although in theory ramdisks are fast but in the real world ramdisks are kind of like an nvme ssd? And, have you tried a ramdisk before? I can't seem a lot of information about this online.
Hi there. Portioning a segment of RAM as a RAMdisk can provide really fast storage since the PCIe interface isn't required for communication with the CPU. There are however some obvious caveats. As you'll be aware, the most critical issue to circumvent is that of data loss in case of system power loss (something that can be somewhat negated with an uninterruptible power supply). In terms of speed, the theoretical speed will be limited by the specifications of the system you have setup (so the hardware and the software managing the RAMdisk). At a guess, your NVMe-like speeds would be the result of a bottleneck in the system (speeds are only as fast as the slowest point in the system). If you are accessing the data directly to and from RAMdisks the speeds should approach that of the theoretical maximum of the memory. e.g. The HP Z840 with DDR4 2400MHz ECC memory should net ~19,200 MB/s (2400 MT/s × 64 bits ÷ 8 [bytes]) as the theoretical max. If you are using older RAM, say DDR3 1600MHz it should net a theoretical max of 12,800MB/s. The next issue is overhead of transferring different file types and how efficiently all the hardware can communicate - which will vary depending on the system specification and design. I haven't explored RAMdisks as of yet, mostly because of the volatile nature of the memory (I mostly seek secure long term storage). Good luck with your system, it sounds like a cool project!
Hello, Your right regarding ramdisks, I wouldn't use it for long term storage. I just got into ramdisks due to the extreme benefits of speed competing with nVme drives. In theory, your absolutely correct. However, for some reason ramdisk to ramdisk on Linux, the speeds are drastically slow. And, I have a fast system with DDR5 memory. I was curious, have you tried using a ramdisk on Linux yet doing a file transfer? If so, what were the results? Also, I do appreciate your repsonse. I'm just trying to get as much feedback as possible since I have been going on google researching ramdisks for a while and the min throughput but so far I haven't seen any results that are reaching the theoretical max, but I have seen results that reach nvme speeds but aren't nvme. I also subscribed too, I do like how take the time to respond to your youtube comments, and so far I do like how you are doing raid 0 pcie bifurcation nvme drives. I love speedy solid state drives! @@racerrrz
@@interactivesage4609 Thank you, I appreciate your sub and the positive feedback. I am in process of uploading a new NVMe video - 980’s in RAID 0 on ASUS Hyper M.2 V2 - I managed ~ 7000MB/s read - PCIe 3.0 with DRAMless NVMes, I’ll call that a win over the aged PCIe protocols lol. Your RAMdisk speed quest sounds like a worthy challenge - and I understand the quest for speed haha. It sounds less likely that the speed limit is hardware, making it more likely to be software, file system or file type that’s causing the limit. In my quick search, this link looked like it could be of use: copyprogramming.com/t/ram-disk-to-speed-up-my-ide What software protocols are you using for the speed benching? It seems FIO would be the best option on linux (HDparm and “dd” as runner-ups). Given the lack of results pushing towards the theoretical max it only really leaves two scenarios. 1) it’s not possible to attain anywhere near the theoretical transfer speeds (maybe everyone runs into the same issue), or 2) the setup can be refined to remove the bottleneck and reach faster speeds. I do not have any experience with RAMdisks so I can’t provide any data to help with your quest. There are a few considerations that could be worth testing: Test different benchmarking software/protocols (in case the software isn’t reporting correctly), ensure your RAM modules are functioning optimally (Memtest86 etc.), test another system with the same protocol (If a lower spec system nets the same speeds it could point towards the transfer/files being the bottleneck.), test different transfer methods (commands like cp, mv, rsync, etc. or different file systems if used [ext4, xfs etc.]). Hopefully you manage to unlock that extra performance!
In 10 years people will be looking at the rtx 4090 with its size and laugh their ass off. Since APUs will have completely taken over . They will seem like ancient technology
Given the rate of progress with technology your claim isn't that farfetched, and right now APUs provide some speed benefits. But with Moore's law beginning to bite back it might slow progress until a viable technological leap is established. My only hesitation with APUs would be heat dissipation. Considering that GPUs like the RTX 4090 generate a phenomenal amount of heat (necessitating their huge cooler), I don't APUs will be the technological leap needed to push a new frontier, but they will bridge the gap. If only quantum computing would make quicker progress, but they are a long way off from reaching the consumer market.
Thank you for the feedback and I am sorry that you found it difficult to follow due to the pacing. It's a fine balance between keeping the video pace fast enough to not waste people's time, and keeping the content easy to understand. Generally the trend is to keep the pace really fast to maximise the amount of information packed into the shortest amount of time. It takes ages to edit content to that level, but it is generally better to keep things at a slower more conversation-like pace. Without feedback I would not know when I have reached the "too fast" point. Noted, new achievement unlocked - I can now slow down again!
@@racerrrz thank you for responding to your viewer comments. Much appreciated and impressed. I too have the Asus Hyper m.2 card, and it works perfectly in my Asus X299 system. Watching this video validated my choice to go with nvme storage. Your content is very good and relevant to maintaining and extracting the most from slightly older hardware. Again, thank you for the content.
@@julianfiacconi709 Thank you for your feedback, much appreciated. NVMe storage remains the best method for some really fast storage. My only complaint right now is that their prices have gone up so much it makes it more difficult to get a Quad NVMe adapter populated. I am working on testing a RAID pool of cheap SSDs for my Mini PC server build - but that was the best workaround I could come up with to counter the recent flash storage price increases.
Hi there. I can't solve what appears to be a PCIe 3.0 compatibility issue with the Aorus Gen 4 adapter, only Gigabyte can do that since it's their product. All I did was to report the issue I experienced to help others make a more informed decision with their purchases. The Aorus will give you higher speeds than what you will retain from a single Gen 3 NVMe, and I gave a method for that (4x NVMes in RAID 0) - delivering on the video title's claim. If it were clickbait it's not very effective, the video hasn't blown up - but I do believe many people would benefit from the video yet still. I did do more testing to confirm the issue. I purchased 4 new 256GB PCIe 3.0 NVMes to again test the Aorus Gen 4 AIC adapter and it again came out substantially slower than the other 3 adapters I tested (HP Quad Pro, Asus Hyper V2 and Jeyi Quad U.2 to M.2).
You ever thought about a Thinkstation P520? Also check this out. This looks so cool. ICY DOCK 2 Bay M.2 NVMe SSD to PCIe 4.0 x8 Removable Mobile Rack for PCI Express Slot Adapter Card (PCIe Bifurcation Required) | ToughArmor MB842MP-B
Hey, I have looked at the Thinkstations and their specifications are really good for their price point. I'll have to keep an eye out for a cheap unit. I have done some reading into the alternative ways to store NVMes but I have not seen removable PCIe NVMe slot adapters. Great find. The ones that caught my eye are the 5.25" bay NVMe adapters. If their prices come down I would be tempted to get one for a quick video, ToughArmor MB873MP-B: global.icydock.com/product_305.html
@@feelsbad1193 Having two native NVMe slots is surreal for a workstation. They really look like solid machines, decent CPU and RAM options too. My only complaint would be the internal space for a GPU. I'll have to check the published measurements but I am not sure you'll be able to fit an oversized GPU in there. But with enough effort even that could be fixed (case swap lol).
@@feelsbad1193 I imagine that heat will be an issue if you manage to use all the NVMes at the same time. I can imagine a RAID 0 with 8x NVMes, or even two of those adapters to really push the NVMe storage front. But it all comes back to end purpose. Right now I am looking at ~2.5TB free space on the new ~8TB RAID 0 pool that I have set up. A few months later I'll need more space - unless I segment projects between NVMe and HDDs etc.
Ah yes - noob indeed. The right of passage is earnt through accumulating hours in the game - with the mission being to gain experience and mastery. I have always been one to quickly figure out game mechanics; and I am good at finding strategies to gain EXP quickly. The irony is that all masters were novices at one point and that their experiences along their journey molded their mastery.
