You do understand that you can find sound card that are in pci-e gen4 8x ! And the same as many graphic card of gen4x16 are do run internally - electrically : only at 8x and even at 4x. Like testing all those nvme drive.. skip the memory chip.. call <cache< and then you see all is about same...

Simply get proper interconnect. sff-8643 and off you go.

i read Intel do keep temp quite lower.. But the Pm983 is only eating about 1.2 amp vs other. Will they throttle limit if just in pc case .. without extra high speed fan on them ?

Hi I plan to put a setup of 4 sas u2 in a m.itx chassis and i got a selection of 3 unit: Kioxia CD6 (gen4) or Samsung PM1733 (gen4) or Samsung PM983 (gen3) As gen4 nvme do have higher sustained write speed, i hope i will be able to get a proper 3gbps of write or even saturate the gen3...

The Highpoint do show perfectly, but the firmware present do help to translate the info. The ssd718x work good for that and even a direct gui tool to config and see thoses smart info.

Of course M.2 is slow and after few second you end up at sata speed mostly. Having full pcie lane to feed U3 disk is quite the best used and whre you get all perfo.

same thing. just advances feature that are only used if you do develop your own motherboard for server application. all card used for nvme are like only using about 20% of the feature of the chip. Hightpoint are nice one. The the one with internal and external port do offer upgrade for future as...

The solution is to get a plx card, that is mostly exactly like an usb hub. no delay... and over 1 slot you get 8. Good solution is card like Highpoint ssd7184 as you can connect internal drive and also external unit for flexibility.

Well, no matter what, if you do not have a retimer, the spec of gen4 do apply and signal lenght path is... very short. And evey connector do add signal loss.

wasn't it a bit problematic at some point as the nic card itself do heat quite a lot and the intel qsfp even more.. ? I look to upgrade, as currently i'm on 25g and it's quite animic and quite the bottleneck.

i try to get the full manual of the chip : pex 8749 , but i never get reply from broadcom or find it. It should be a pdf (data book) of about 200-300 pages. Any do have it ?

Hi I do wonder about the different compatibility and usage of different genration of hba. So first, if a Micron 9300 u2 or a consumer normal m.2 drive in an hba that support only sas 12g vs nvme.. any data corruption or decreased life ? And while the microchip HBA1100 do run at sas and sata...

On the PEX 8749 card, is any had found a way to mix / readjust the config firmware on those card to have a mix of speed as : getting x8 speed on 2 or 4 port and the rest other 4port run a 4x ? I did see somewhere those card as all using the pex 8749 chip can output all 8 port as 4 group of 2...

You try many thing at same time. you had issues on your raid card, the asus tb extension is just alone a problem generator on his own. And booting the eeprom of the raid card, after the tb.. many time the pc do reset as the tb is not detected... and too what is the cable used for the enclosure...

Hi I want to know if we can get the highest sustained sequential write, by using an nvme Gen4 into a gen3 slot. On the transfert and ref, with a samsung gen3 970, after 20sec of 3gbps it drop to 1.5gpbs for the rest of time(after 2,4,9min). So no dram effect and we see an usb10g give about the...
