What’s the difference between old and new gen?
Gen 3 vs Gen 4. Speed.
Not really noticeable unless you're transferring large amount of data, but if you've got a motherboard that supports Gen 4 then why not get a better drive that supports it.
You sure that's not WD Black SN750 SE?
I thought with SN550, the issue is new gen uses inferior NAND (could be QLC).
What do you mean by Gen 3 vs Gen 4 speed?
The new model is Blue SN570. It is still a Gen 3 SSD
Old gen is TLC
New gen is QLC
translation: Old gen is an ok entry level drive. new gen is shit on a stick
Noone is selling you a PCIe Gen 4 500gb SSD for this kind of money.
Afaik it has met ps5 expansion standard
Nice
Also Crucial P1 1TB is $99
Kingston KC2500 with better R/W and IOPS is also $69 on backorder for Amazon or $65 at PLE at the moment. WD Blue might be better for laptops though as I believe it's a single sided PCB?
Banger of a price tbh, just know it's Gen 4, even though it's rare to make use of that speed in the real world right now.
SN550 is PCI gen 4? Really? Do you have the link?
It's definitely not Gen 4
Yeah price is good.
Please get your info correct.
Blue SN550 is a Gen 3 SSD. The new model SN570 is still Gen 3.
How can I find out if my Motherboard supports Gen 4?
I got a HP ENVY Curved All-in-One 34-b1xx
Did some digging it says "One M.2 socket 3 key M, 2280 type for SSD"
Your motherboard does not support PCIe gen 4. However, I don't understand why people keep on indicating this is a PCIe gen 4 SSD. I thought the issue is the newer gen of these actually use inferior NAND.
The PCIe gen 4 change is for WD Black SN750 SE. However, it uses the lowest end PCIe gen 4 and is DRAMless. It makes no sense for WD to make SN550 PCIe gen 4. They don't want to sell SN750 SE at a premium?
Thanks for you reply and explanation, unfortuantely most of it went right over my head…
Would that then mean that this SSD is probs a really good option for me?
Whether this is a good option comes down to your budget and objective. It is hard to find a bargain price 500GB SSD (in terms of price per GB). Some 1TB SSDs currently offer best price per GB.
Basically, is 500GB more than enough for you and more importantly, are you quite happy with the price. If the answers to both are yes, then it is a good option for you.
@Hashstrid: Crucial p1 1TB was 90 bucks for 40 mins the other day, current price is 100 bucks which is damn good IMO, got one myself for the XPS, might get another…
@Hashstrid: For primary SSD, I would avoid Crucial P1 or any QLC based SSDs for now. It's okay as a secondary SSD or for gaming where you care more about reads and the subpar sustained writes of QLC isn't generally an issue for gaming.
@netsurfer: What would you recommend?
I want to get an 1TB nvme and have windows and softwares on it
Then get a 2 - 4 TB SSD 2.5" and have games/movies on it
@Hashstrid: If you want to wait, then wait for a good deal on Samsung 970 Evo Plus 1TB. It's an overkill for most people, but it doesn't cut corners like some of the other NVMe SSDs. However, if that's out of your price range, then any TLC NVMe SSDs would be okay.
What's the best value in 2tb M2 these days? For a 5900x / x570 board?
PNY XLR8 CS3040 2TB
Gigabyte 2TB Aorus
Basically Phison E16 based PCIe gen 4 SSDs. They are basically mid tier PCIe gen 4 SSDs.
Would anyone really notice a difference between gen 3 & 4? They're both still way faster than the mechanical drives we were all using only a few years ago.
You may notice it from initially running benchmark and the newer & larger dynamic turbo write (SLC cache). One of the changes in most PCIe gen 4 SSDs is that the controller now does dynamic turbo write. What it does is that, instead of having just 10GB of SLC cache, it allows the SSD to write in SLC mode to about ~100GB when the drive is empty and the SSD size is 1TB (basically up to 10%). So initially, you may get the impression that it is faster. There is only a small number of PCIe gen 3 SSDs which does that.
The fact that (1) there is zero consumer level MLC PCIe gen 4 SSDs and (2) WD SN750 SE, which is really a cut down WD Black SN750 with the cheapest possible PCIe gen 4 controller (crippled 4 channels version, instead of typical 8 channels) actually works in PS5 shows that we don't really need PCIe gen 4 and a lot of nice benchmark figures are mostly SLC cache tricks and multi-channel setup (which only benefits sequential read/write).
At the moment, we have not seen any QLC based NAND PCIe gen 4 SSDs. Also, even cheapo or not quite true PCIe gen 4 SSDs still use reasonably decent TLC NAND flash.
However, if WD SN750 SE and Samsung 980 are a trend of what's coming, we are now seeing cost cutting being done on PCIe gen 3 SSDs and the disguise these newer controllers allow (with the new dynamic turbo write) can really trick benchmark software and possibly fool consumers. Once the drives are filled, things can get ugly. A lot of reviewers don't test them properly and we (consumers) can get the wrong information.
What do your guys recommend for HP Probook 430 G8 W10P laptop ssd upgrade from 256g to 512g/1tb?
