Thanks to this video, I think I'll put a USB 3.2 Gen 2x2 card in my PCI 3.0x4 slot for my NVME enclosure which supports Gen2x2. No use in bottlenecking my USB type-C 10gbps connection with 900-1000mbps transfers. Great video!

Hello R Graz, Welcome! Smart Choice! Appreciate Your Comments!

​@@BuildOrBuy Hi Gill, I just installed the Inateck Redcomet U27 USB 3.2 Gen2x2 card on a PCIe 3.0x4 slot and crystal disk test (1T samsung 980 non-pro NVME) was 1780 MB/s / 1690 MB/s. I was expecting higher since my 10gbps MOBO port was 1065mbps / 1030mb/s. Is that what I can expect from Gen 2x2 or should I get higher? Thanks! EDIT: I guess the speed is limited by the enclosure itself which is a Gen 2x2 enclosure and I'm using a CtoC cable rated at USB 4.0. The enclosure is the Maiwo Dual Bay M.2 NVMe Duplicator Docking Station so I guess the limitation is with the enclosure electronics itself?

[@BuildOrBuy]

Hi@@rgraz4929, Everything with these Specs is all about Burst mode, not Sustained Throughput. Plus We have to allow for Overhead of the Interface. To compare, Test and Verify Your 10Gbps USB-C then Test and Verify Your 20Gbps USB-C 2X2. Can You correlate a percentage from each?

[@HAL09000]

I paired the StarTech PCIe card with the SanDisk Professional Pro-Blade Transport on my old (2011) computer with an Asus M5A88-M motherboard. With this set-up the magazines benchmark at 1.5 Gigabytes per second. This outperforms my new computer with an Asus ProArt Creator Wi-Fi motherboard which has Thunderbolt 4 ports, but does not have a 20Gbps USB port. The benchmark shows as 1 Gigabyte per second. I expect to get better speeds on the new computer when the Pro-Blade Station with it's Thunderbolt connection comes out. 🙂

[@BuildOrBuy]

Hi HAL09000, Perfect timing! Interesting Stats. Breaths new life into an older Computer! Yes, the Pro Blade Station should make a big difference in Performance on Your ProArt Motherboard! We're right in the middle of this! SanDisk is really stepping up their Pro product eco system for Content Creators! We also need a Rackmounted version as well as a Desktop version! Thanks for Sharing! This helps Us to make better Videos Viewers are asking about!

[@user-cq6fk5go3s]

Makes sense thunderbolt being chipset driven. If I move or access large amounts of data on the onboard storage the task is quickly set in motion and maintains speed ect. Data from External to onboard still typically responsive and maintains tb bus speed limits. If I work between external to external on separate TB ports there’s a lot of “preparing” time spent before data moves. Ram usage spikes ect.

[@BuildOrBuy]

Hi user-cq6fk5go3s, Welcome. As the Thunderbolt specs go forward, specs tighten up and each iteration becomes more Vendor exclusive. In other words, single brand. And that's not how that's suppose to work. When Thunderbolt works, it works. And when it does not work, it's useless. Whereas, USB-C 20Gbps is easier to implement. Just now seeing Your comment.

[@not8brand]

finally someone dives into these details, been looking everywhere for someone to explain how this works because anything over 40GBs would seem to logically be bottlenecked by the DMI speed of the chipset unless the connection was routed directly to the CPU or if somehow the usb/tb headers some how added more bandwidth or more lanes for the port...but motherboard manufacturers don't seem to want to explain this part and so I have no idea if spending money to have those connections is even worth it....

[@BuildOrBuy]

Hi Christopher J Sanders, Welcome! Intel Marketing! Hard to wrap Our mind around Thunderbolt once We start trying figure out Thunderbolt! Supposedly Thunderbolt Data protocol Encoding scheme. Just based on PCIe, hard to expect anything more than PCIe Bus Data Transer Rates can achieve. Plus, anything proprietary is a hassle to implement. You bring up an excellent point. Considering Consumer Desktop Motherboards have limited Shared PCIe Resources, What's the best use of 4 PCIe Lanes. M.2 NVMe PCIe SSD Drive or Thunderbolt. Appreciate Your Comments!

[@not8brand]

@@BuildOrBuy thanks! And that's exactly been my question regarding adding a thunderbolt pcie expansion card, I'd much rather keep an M.2 NVMe SSD and my graphics card going to the CPU than to give that up for a thunderbolt connection, I was just hoping I was missing something about adding thunderbolt to a motherboard that would actually allow 40 GBs, but nothing I have researched about thunderbolt headers on a motherboard has convinced me that this is true. In the end I think USB 3.2 Gen 2x2 is all the speed I'll really need for a while.

[@BuildOrBuy]

Hi@@not8brand, Now You see the bigger picture! Implementing Thunderbolt 4 / USB4 is Motherboard Brand specific! Every single Motherboard that supports such is proprietary! No swapping Thunderbolt of one Manufacturer to a Motherboard of a different Manufacturer. The Motherboard Thunderbolt Header is now Specific to each! Proprietary! USB-C 20Gbps 2x2 only Requires a X4 Slot to implement if not already on the Motherboard! Keep it Simple and Make it Work! Hope that helps!

[@not8brand]

@@BuildOrBuy huge help, great work! Thanks for all the help.

[@BuildOrBuy]

Hi@@not8brand, Absolutely! You'd be amazed how some Viewers seemingly are more committed to Thunderbolt emotionally that the actual Throughput! More of a want than a need.

[@ChrisM541]

Again, huge thanks for the info and excellent advice here. That MSI motherboard looks very interesting (and any others like this) with 3 PCIe x16 lots, wired as follows... E1 PCIe 5 x16 (CPU) E2 PCIe 5 x8 (CPU) E3 PCIe 4 x4 (chipset) I hope(!!) this would allow an nvme expander card (e.g. Asus Hyper x16) to be put into slot E1 for 4 M.2 SSD's - while - allowing slot E2 (or E3) to take the dedicated gpu. I realise the current Asus card is a Gen4 one (so 4 x Gen4 SSD's) but would be upgradable (with a new expander card) to 4 x Gen5 SSD's later when options become available. Maybe there's going to be Gen5 expander cards soon? The E3 slot in the MSI motherboard is PCIe4 x4 = PCIe3 x8. I'd be surprised is there's a significant gpu horsepower downgrade even using this slot? (a lot of upscaling trickery e.g. textures still going on at 4k by many devs) We should also research the likelihood of certain motherboard functions being downgraded or disabled (e.g. onboard M.2 or USB slots) when populating some/all of the 3 PCIe slots - that's very common for desktop motherboards, with their limited PCIe lane counts.

[@BuildOrBuy]

Hi Alexis K, I'm honored! Appreciate Your Comments! You're right about possibilities! Keep in mind, when thinking about a Consumer Desktop Motherboard with a 16 Core CPU, not enough CPU PCIe Lanes due to Shared Resources. To install a X16 Quad card Yes will require that 1st X16 PCIe Slot. Preferably the GPU would be in the CPU or a separate GPU would have to go to that 3rd PCIe Slot through the Chipset. What about that 2nd X16 PCIe Slot, mechanically? As You've pointed out is only X8, electrically and is a Shared CPU PCIe Resource with 1st X16 Slot. Thus if both Slots 1 & 2 are used simultaneously, each becomes X8, electrically. Bummer, right. This will be the situation on every single Consumer Desktop Motherboard that can only use a 16 Core CPU. Just not enough CPU PCIe Resources! And as mentioned in the previous Video, Gigabyte has announced the Aorus GEN5 AIC Quad AIC. Same requirements, 1 PCIe Slot, Bifurcated in the Bios to x4x4x4x4. To reiterate, a GPU either will have to be CPU based or installed on a Chipset PCIe Slot which is more than likely to be 4 PCIe Lanes. Crazy, right! We need someone willing to Test and Verify Results of a GPU Performance Test while running the Gigabyte Gen5 AIC with 4 PCIe 5.0 M.2 NVMe PCIe Drives!

[@mr_nemo24]

Hi Gill!! I saw your last video talking about this (the usb 3.2 gen 2x2 = 20 Gbps). It was small piece of info but quite interesting. Love this extended video. However you inspired me to search and buy an 20 Gbps USB-C expansion card with the previus video already XD, the Inateck Redcomets U27. I bought ICY BOX IB-1922MF-C32 case/adaptor for one Western Digital Black SN750 NVMe 1TB SSD M.2 PCI Express 3.0. Crystal Diskmark says 2070MB/s read and 2080MB/s write. (I am not going to make the 10 Gb Ethernet connections in the end, too expensive). I am using all of this to reccord Blackmagic Raw and fast transfers. Shame the BMPCC6K has a 10Gbps usb-c connection and still can not reccord 6K BRAW QO 50fps. I don't understand how can be realeased a camera without a way to reccord the highest resolution + fastest frame rate, considering that the best way is USB-C way. Obviusly I don't reccord this frame rate and quality, but I thought it was enough fast. I notice that this technology is quite better than the Samsung T5, but there is no such big difference. The big difference is at transfering files.

[@BuildOrBuy]

Hi Mitxel Sadaba, Excellent! Very good point to know and understand and explore Our options. 20Gbps USB-C needed more coverage than was possible in previous Video. 20Gbps USB-C has an easier infrastructure to install and embrace. Going forward right now this looks like the best We can do to implement on the most amount of gear based on requirements. Blackmagic must have something else going on yet to be released! Yes. 20Gbps USB-C is more affordable! Thanks for Sharing! We need more High Performance Storage Solutions that are affordable!

[@BuildOrBuy]

Hi Mitxel Sadaba, Was just looking over Specs of Blackmagic Pocket Cinema Camera 6K G2 on B&H and that indicates Recording Spec on 10Gbps USB-C for 6144 x 3456 / 50 fps but not 6144 x 2560 / 50 fps. Maybe that's what You encountered as the problem. Hope that helps!

[@mr_nemo24]

@@BuildOrBuy Hi Gill! No, that is not the problem. You can already reccord 6144x2560 60fps (edit: not 50, also 60) Q0 with the Samsung T5, normal external SSD (NOT NVME). Is less info than the whole sensor per second, so is more affordable. The problem is that the USB-C 10Gb connection doesn't really give you that speed, I guess it gives around 700 MB/s. That is the speed I get on transfers of the BRAW files at a rear usb 3.2 gen 2 connection with the external m.2. However I get around 1,2GB/s with the 20 Gb USB-C adapter now. Whatever Crystal Diskmark says is not 100% accurate to real transfer situations. You know that. And 6K 50fps Q0 is around a minimum 805 MB/s reccording issue. That is what I think and what I remember from my research. Can it hold longer reccording 48fps than the T5? Yes! But also can't handle it and stops. 45 fps? Seems no problem neither with the T5 or the m.2, at least for some minutes. I guess at some point the T5 will stop and will do it before the m.2 does. Haven't been testing for so long. So, that is why I say, the big difference is at transfer situations. Not so much while reccording. Wish the USB-C speed was just a bit faster at the BMPCC6K.

[@BuildOrBuy]

Hi@@mr_nemo24, Got it! Solving a Problem starts with knowing parameters and scope. The next concern would be, based on Your Description, the Codec. According to braw.info, the Blackmagic Pocket Cinema Camera 6K in 6K Resolution with Compression of 3:1 and 50 FPS Calculates to 539.04 MBps. www.braw.info/capacity And that looks like 10Gbps USB-C should do the job. Agreed, most Tests are dealing with Burst mode and not actual Throughput such as is the case with Streaming or in this situation, Recording. The Blackmagic Speed Test would be more appropriate since that Test is about Throughput on PCIe 3.0. According to Highpoint, the Blackmagic Speed Test does not yet Test PCIe 4.0 which is understandable since Blackmagic deals with the Throughput of Recording. However, curious 10Gbps USB-C did not accommodate Your Recording based on the above Results by that Codec where it should. I wonder what's causing the issue. Having this Info You've shared helps Us to make better Videos! Thank You! BTW: Just realized, that Calculator does not indicate values for 60 FPS. And that's a big difference! Even the Storages Rates as listed below do not include that Data Rate. Very interesting. Storage rates based on 30 frames per second. That should then double at 60 FPS. 6144 x 3456 (6K) Blackmagic RAW 3:1 - 323 MB/s x2 = 646MBps on USB-C! Does that sound about right? 646MBps / 60 FPS vs 539MBps / 50 FPS using Blackmagic RAW 3:1 Codec.

[@mr_nemo24]

@@BuildOrBuy The page is right at some things. I use an excel finded at youtube. Better one. You can't reccord with the whole sensor at 60 fps in any resolution. In order to get higher fram rates than 50 you have to decided how much crop. Example: 6K 2:40:1 aspect ratio gives 60 fps, or 3,3 crop factor gives 120 fps but 2.8K resolution at BRAW. Many codecs or resolutions. Depends on what you want. The issue here is the whole sensor size, 6K Q0 50 fps can't be (376.64 MBps) less than Q3 (539.04 MBps) that's not right. My research, thanks for the info other youtubers give, is that Q0 is at least 805 MBps. No problem reccording Q3, even with the Samsung T5.

[@DrewryPope]

i think it's the dp bandwidth again. 32 pci3 + 8dp = 40 64 pci4 + 16dp = 80 with the dual port that might need 2 dp in

[@BuildOrBuy]

Hi Drewry Pope, Welcome! Not sure I understand. Are You referencing DisplayPort? PCIe 3.0 has a throughput of 1GB per second per lane for an overall data transfer rate or bandwidth of up to 32 GB/s total. PCIe 4.0 doubles that. 20Gbps USB-C is PCIe 3.0. USB4 V1 is PCIe 3.0 whereas right now looks like USB4 V2 is PCIe 4.0 according to the ASMedia ASM4242 Chipset which is yet to be released. DisplayPort is the 3rd option of USB-C to be enabled if supported as DP ALT Mode. The ASMedia ASM3242 Chipset supports 4 lanes upstream port of PCIe 3.0. Bandwidth is definitely going to be an issue depending upon the Chipset location on X670E Chipsets. And definitely not enough PCIe Lanes for everything!
