So it looks like the 980 Pro 4.0 is coming out soon, and a) apparently benchmarks way better than the current pcie 4.0 SSDs and b) is expected to cost like $350 for 1tb or something lmao

Almost Smart posted:Question before I bone myself - I just cloned an SSD to a new NVMe drive of the same size. I've confirmed that the new drive is the boot drive and can disable the older drive with no ill effects, but I'd like to keep it around for storage. I was going to reformat the drive to clear it out, but Windows is warning me that it has processes in use. Is it safe to ignore the message, or is there a better way to go about cleaning it out? Yes, as long as you're sure that you cloned over the whole thing including boot ("EFI system partition" in disk management) and recovery partitions. Windows doesn't like to format itself, and tends to object. I think just seeing that an old page file exists on the other drive will make it declare that the drive is in use. You can ignore the message and format the main partition, but you can't format / delete a boot partition with any of the normal GUI tools. So the easiest way to wipe an old OS drive that you want to reuse is to use diskpart. Follow instructions carefully. The clean command will completely wipe the drive by deleting the partition table. Then you can use the whole drive normally and not worry about having 2 drives with boot partitions. sean10mm posted:So it looks like the 980 Pro 4.0 is coming out soon, and a) apparently benchmarks way better than the current pcie 4.0 SSDs and b) is expected to cost like $350 for 1tb or something lmao lol samsung gonna make bank on all the PCMR guys who are panicking that a console might have something better than them

How long after the previous models did the EVOs launch? Probably not a bad idea for Samsung to only sell the PRO for the rest of the year + grabbing insecure PCMR folks, but I'm not actually sure what historically moves volume for their pro drives. OEM versions, not client versions? e: maybe they'll sell pairs to people to RAID 0 to ensure they have the biggest number in the room? movax fucked around with this message at 07:57 on Aug 31, 2020 |

Tweaktown has an article up with specs for a phison e18 based rocket 4 plus so I doubt samsung is going to be able to maintain a monopoly on fast pcie4 drives for long. Probably won't have the luxury of holding back the more cost effective option unless they want to cede that market.

Without direct storage access from the GPU it seems like it'd just slam the CPU, but maybe I'm missing something? The only real salient difference between what the PS5 is doing vs normal PCIe is that they've got a decompression hardware block in the SoC to allow them to hit a theoretical ~9GBps transfer off a 5GBps disk instead of being limited to PCIe 4.0 4x's ~8GBps theoretical max and requiring a drive that can actually dump data that fast. With DMA in PCIe, dumping from disk to RAM shouldn't be much of a load on the CPU so long as the data doesn't need any modification in-flight. The bigger question is, I think, how will that data be used. Since the consoles are using a shared memory for both system and VRAM, anything in there can be used by both the CPU or GPU without additional shifting around. Obviously that's not the case on a PC. I know NVidia has GPUDirect Storage/RDMA to allow a local drive to move data directly into GPU VRAM, but I have no idea if that's actually been implemented in gaming engines or if it's just something that's being kicked around at HPC labs. If not, having to take a trip through the CPU and system memory to get to the GPU would add a chunk of time compared to what the consoles are able to do with streaming assets in and out. Then again, we'll have to see if they actually even do much with it. Part of the reason that the speed of being able to load assets off the disk was such a factor in the current gen of consoles is that (1) that speed was terrible, and (2) the system RAM sizes were tiny (8GB for system+gpu together), so there was a ton of asset control that had to happen. With 16GB to play with this time around, they may simply not need to do as much asset swapping in the first place. Plus the XBox is limited to ~5GBps, so anything not PS5-exclusive is gonna have to cater to that, anyhow.

Can you move hiberfil.sys to a different drive these days? A 1 TB C:\ drive should be enough but if you have a TR / HEDT setup with 64-128 GB of RAM, that's an easy 10% capacity loss right out of the gate. I've been limping along with 512 GB as an OS drive on a machine w/ 32 GB of RAM and hover ~100 GB free as Windows accrues SxS / windows update cruft.

movax posted:Can you move hiberfil.sys to a different drive these days? No, it has to be on the boot drive -- it's loading hiberfile at the very start of the boot process, before drivers for storage. But if you have a TR HEDT, why not just disable hibernation altogether? S3 sleep uses a minimal amount of power (and shouldn't really be much more with a monster PC than a normal desktop, all those high-power parts are off). You also lose fast boot, but win10 boots pretty drat fast. And resume from sleep is faster than fast boot -- I go weeks between reboots because I use sleep for 'off' nearly 100% of the time. Hibernation is IMO pretty useless for desktops. Shogunner posted:I know ADATA is not a first-choice brand, but is there any reason to not use this as my only drive on a new rig?

I mostly keep hibernation enabled so my UPS can trigger it when a power outage happens. I don't use S3 sleep at all — leave my machine on 24/7, mostly because having seen how the sausage is made, I remain forever skeptical that ACPI power states work without loving anything up / causing a BSOD / forcing a reboot eventually. Maybe it's time to try it again, though.

ADATA is a second-tier company in general, but their SSDs have actually been quite good and excellent bargains compared to your usual suspects. I've got an SX8200 Pro, myself, and it's been great. Samsung's entire lineup is, frankly, not worth the prices they're charging anymore--they're coasting on name-brand recognition far more than having an objectively superior product with the EVO line. Their Pro line is still good, but even more expensive.

I literally just transferred my ssd over to a Sabrent rocket 4.0 yesterday and now the rocket 4.0 + is announced today. Bah. I use the PC it's in purely for gaming so it's not like it makes that much of a difference anyway, but I probably could have saved some money had I waited another couple months.

I just want to reiterate that, while I've been an Adata proponent, I recently described multiple Adata SSD failures, including the previous-gen SX8200. While the sample size is small, I'd suggest trying other brands as there are many similarly-priced options nowadays.

It should also be said that even though the SKHynix P31 is getting really good benchmarks and reviews...for all any of us know it could eat itself alive and generate a singularity after six months of regular use. There are always outliers to MTBF.

I've always liked the stability / performance I've gotten from Samsung controllers / their drives which is why I stick with them even if they aren't the cheapest / most cost effective anymore. SK has a lot of presence as OEM drives, so not a "new" entrant — just the first time they're actually releasing directly to consumers instead of OEM. Pretty sure XPS 13s show up with either SK or Samsung OEM NVMe sticks.

Do NVME drives have PCIe lane flexibility like other PCIe devices or do they always expect 4 per device? Could a motherboard use PCIe4 to offer two M2 dual-lane slots (each equivalent to PCIe3 speeds) rather than one slot at twice the speed?

Pablo Bluth posted:Do NVME drives have PCIe lane flexibility like other PCIe devices or do they always expect 4 per device? Could a motherboard use PCIe4 to offer two M2 dual-lane slots (each equivalent to PCIe3 speeds) rather than one slot at twice the speed? Every compliant device should downtrain as part of the link negotiation process, but then that device can choose to go into whatever state it wants if the width is too small for it. AFAIK no NVME drives refuse to run at small link widths, you're just not going to get the speed you want. M.2 was design with x4 lanes as the assumed "standard" — absolutely, if the PCIe root complex supports it, you could put a bunch of 2 lane M.2 slots all over the board, but people would then have to buy matching x2 PCIe 4.0 devices to enjoy full performance, and those things aren't going to happen at the same time. A fun theoretical all-flash storage array could be an add-in card (I mean, I'm describing enterprise NVMe here I guess) that takes a x16 link and offers up 4 x4 PCIe 4.0 slots for drives. Samsung and friends just already make x8 width NAND controllers that they throw onto HHHL cards for servers.

I have a prebuilt with an nvme m.2 port that's only two lane. It's possible this was user error, but I decided to go with a SATA drive when upgrading from a hard drive because I saw online reports of issues with getting nvme drives recognized.

The small optane m.2s were x2 only so it could be that was what was planned for that prebuilt.

Could a motherboard use PCIe4 to offer two M2 dual-lane slots (each equivalent to PCIe3 speeds) rather than one slot at twice the speed? Yes, in the sense that it could split 4 lanes over two slots for a 2/2 setup. The catch with that is if you slapped a current PCIe 3.0 NVMe drive into such a slot, you wouldn't get "full PCIe 3.0" speed, AFAIK, you'd get half of it, because the drive will only see two lanes and can only speak PCIe 3.0, so it's now working as a 2x PCIe 3.0 drive (so 2GB/s), even though the slot could support being a 2x PCIe 4.0 link (4GB/s). Basically it wouldn't end up being any different than if you just split a current 4x PCIe 3.0 link in half if you're using current PCIe 3.0 drives. But if you were using PCIe 4.0 drives, yeah, you could get two 4GB/s slots out of it instead of one 8GB/s slot.

Samsung and friends just already make x8 width NAND controllers that they throw onto HHHL cards for servers. These exist, but note the compatibility. Regular consumer chipsets / CPUs can't use them because they can't do PCIe bifurcation on their own. Threadripper and Intel -X series can because they're inheriting that ability from their server counterparts. (Though for real enterprise they aren't gonna use some add in card with m.2 slots, because installing and replacing drives would be a PITA. You get NVMe u.2 drives.) On standard consumer mobos, anything that increases flexibility with PCIe lanes requires extra bridge chips on the board which increases costs. That's why on a more expensive board there will be 2 slots designed for GPUs, and if you use the main one it's 16x but if you plug anything into the 2nd one it splits that 16x into two 8x, both using the same direct CPU link. There's an extra chip doing that. On a cheap board they'll just put a 4x chipset link into a 16x full size slot and call it good. So while NVMe drives, like all PCIe devices, will accept down-shifting to fewer lanes than their max, there are limits to how useful this is in practice when most mobos are almost completely static in their routing.

So Phison just poo poo in Samsung's corn flakes: https://www.guru3d.com/news-story/sabrent-next-gen-rocket-4-plus-pcie-4-ssd-designed-to-kick-samsungs-rear end.html Gotta admit, I'm enjoying this new environment of tech companies not waiting for conventions to mic drop each other. Obviously R/W isn't everything, and I'd imagine both drives will get toasty, but since Phison has proven they'll license to anyone, it'll definitely make the Samsung Tax less palatable.
