yeah, It reads like I was meaning vertical, like a chewing gum stick on its end, but i was meaning on its side, like memory slots, yes
MLC and TLC also have this problem. Its due to the number of memory channels iirc. There are generally 8 memory channels per ssd, and when you fill up half the drive, you basically lose half of the controllers, because those chips are full. edit : Its actually because when near full, you have partially filled sectors in the flash chips, and to fill that flash up, it has to copy the actual data, add the new data, and write back. A lot more than just writing. The problem is only with writes iirc, although I could be wrong. Reads should be just fine, no matter how much the drive is full. edit : https://www.howtogeek.com/165542/why-solid-state-drives-slow-down-as-you-fill-them-up/ Link to explanation of why ssd's get slower as you fill them up.
I use SATA SSD's in a caddy system on my PC this way I have separate SATA ssd's with different builds of Windows. This wouldn't be possible with M2 SSDs
Now, I don't need another M.2 NVMe, mine is fast and big enough, but my other storage needs are based on reliability, density and price, as my 3 HDD, and none of them saturates a Sata 3 connection, nor a dvd reader does. So, if we are planning on gaming or working on budget, I don't get why we need so many NVMe. If the answer is yes we need it, then there exist HEDT platforms with many M.2 slots, where to throw the money. For me the balance is having an ultra fast drive for the OS, programs and on course workloads, and many other many TB big storage discs for data that will last the more the better, and save enough money for the rest of HW, SW, taxes, food, etc. My case and opinion. PS: AM4 platform always keeps 4x lanes for M.2 from the CPU reserved.
Well, that sure is a bit elitist... You can be a hardware enthusiast without buying into "latest and greatest". I agree with all of this. We're reaching a point where there's only 2 reasons to want multiple drives: 1. More capacity than what a single drive is capable of storing. 2. Redundancy. For the vast majority of M.2 users, a single drive is (or at least can be) sufficient. IMO, RAID1 is a waste of money for NVMe drives in general (regular compressed backups are a more sensible choice). RAID0 will overall hurt everything that gives M.2 a superior performance advantage over SATA, so if all you care about is large capacities with good sequential read/write performance, might as well go with SATA. So all that being said, since M.2 drives aren't hot-swappable or quick+easy to remove, I really don't understand what the point is of having many of them. You could argue "one could be used for a cache drive" but at that point why don't you just use one big cache drive and then use all SATA storage? The end result will be mostly the same at that point. I find a NAS is a great way to store everything that doesn't demand high performance, like media and documents.
Shure, I will get one in another place, maybe at home, to backup important data in different places to avoid disasters
Actually I meant for just everyday use, not just backups. You can mount network drives to be treated/recognized as another hard drive. But yes, they're great for backups too.
I have two m.2 NVME slots on my boards but if i try using both in conjunction with my GPU the second m.2 NVME slot uses less lanes. So yes, they are taking it into account but on our backs. I am not going to use M.2 SATA due to "slower" speeds. That tickles me you even mentioned it, almost as much as seeing people driving really fast vehicles in the US. Yea, I have the headroom but I am limited to 60mph, not giving into that marketing technique.
Yea Wifi card, the only way to get decent speeds my friend. ASUS PCE-AC88 is what I am currently using until AX becomes available. You cannot get better reception, especially with some of these build in on mobo ones.
Yeah. I am using ASUS PCE-AC68 which is enough for my ISP tariffs. As for SSDs I am happy with my SATA SSD.
On Intel there's a difference between cpu pci lanes for the gpu to use and motherboard pci lanes. My 8700k has 16 cpu pcie lanes for graphics and they are tied to the gpu pcie slots. I also have 24 for the chipset (which is effectively connected to the cpu by a additional 4 pcie lane link). Only the gpu uses the 16*cpu lanes, and everything else goes on the chipset which with 24 has plenty although you might loose the odd SATA port if you run your nvme on 4*. note: I suppose if you plugged in an add on card into the 4* pcie slot then that's going to drop your main gpu to 8*, but I am assuming you are just using the nvme slots on the motherboard which use the chipset lanes.
i wonder how much software progress we need before nvme shows a substantial improvement over sata3 ssd are now only twice as expensive, 1tb hdd is around 50$ vs 90-110$ for ssd, we are almost there...
I don't understand your statement above. NVMe already show a substantial improvement over SATA3. My best SATA gets 520 whilst my NVMe gets around 3700
Nothing wrong with SATA 3, if the most you're doing is gaming. My 4 TB Samsung 860 Evo does just fine.
Sata 3.0 SSDs are good enough to me performance wise, but I'm considering to buy a NVMe just for boot drive when I upgrade (price will tell).
They both work just as fine for regular use and gaming, but there are obviously more benefits with the smaller form factor and not having to use 2 cables for every drive.
You're missing the point here. M2 SATA has no real advantages whatsoever and needs to die off quickly We just need more PCIe lanes
