Apparently it's $50 off if you spend more than $200 on Samsung.stor?
Where?
It popped up when I clicked on free game redemption link. Not sure the price on that Samsung store though.
Does that work out to be cheaper than this deal?
Only 1 SSD seems to be available for sale on the samsung store though. The 860 EVO SATA III M.2 2TB for $529
Ignore. Not available on Samsung stoe
is crucial mx500 better than 860 qvo?
The crucial MX500 is comparable in performance to the 860 Evo. So yes, better than the QVO.
860 QVO is comparable to bx500
I read lots of bad comments about the crucial brand (from other ozbargain posts), IMO stick with Samsung or kingston etc
Is it worth getting the Pro over the Evo Plus NVMe? $49 difference for same size drive
Gabos. I think of it as not worth it performance-wise but it's a small enough hit that you'd pay $50 extra if the evo was out of stock and you didn't want to fluff around going to another store.
Thanks mate, performance was my main query
All Nvme drives are maxing out at PCI3.0… The new PCI 4.0 drives are the thing you want.
But in the real world you will never notice any difference between them. Good QTY Sata SSD's are hard to tell apart from nvme drives unless you copy huge files all the time.
What are you talking about? PCIe 3.0 x16 throughput is ~16GBps, do you know how hard it is to saturate that much? For reference the Samsung 970 Pro, one of the top tier NVMe SSD is rated at 3.5/2.5 GBps which can't even saturate PCIe 3.0 x4. Even the upcoming PCIe 4.0 Samsung 980 Pro which is a monster at 6.5/5 GBps can't even saturate PCIe 3.0 x8.
Not even top tier GPUs can saturate PCIe 3.0, let alone SSD.
@rookie317: Most NVMe slots and adapters access 4 lanes so they would have a theoretical 4000MB/sec maximum bandwidth. In the real world one would not be able to reach the theoretical limit, so 3500MB/sec is around the ceiling for PCIe 3.0 drives.
PCIe 4.0 is double the speed of PCIe 3.0, so a PCIe 4.0 nvme drive connected to 4 lanes approach the 8GB/sec bandwidth limit (so around 7000MB/sec).
@navjay: Did you conveniently ignore PCIe card? They can take the x16 slot on the mobo no problem. How do you think people have been RAIDing 2 or even 4 SSDs on a single PCIe x16 slot? HHHL cards are pretty common for the exact reason.
Yes I have never seen a M.2 slot with x8 lanes but that's the limitation of M.2, not PCIe. And in the OP, as well as mine, we never once mentioned M.2 slot, his statement was "All Nvme drives are maxing out at PCI3.0" which is far from truth, if you can't see that I don't know what to tell you.
I'm aware of the benefits of PCIe 4.0 when one lane has twice the throughput, I didn't pay premium for x570 for no reason. But that's another story entirely. Oh and can you show me the source of that 3500MBps or was it just a guestimate? 3.0 x4 theoretical maximum bandwidth is 3940 MBps, I'm sure there's overhead but your number seems extreme.
@rookie317: Most single NVMe PCIe adapters/cars are 4 lanes. The dual ones are usually 8 lanes for RAID0, but your argument is still moot. Have a think about it - 8 lanes gives a total theoretical throughput of 8000MB/sec, and since it is a dual m.2 NVMe adapter, then it will still be a theoretical 4000MB/sec per drive. The amount of lanes a PCIe device uses is tied to the device, not always what slot you plug it in to. I can plug an old x1 usb pcie card into a full sized x16 slot but it won't use all 16 lanes. I assume you are not talking about big enterprise NVMe drives that are not of the m.2 form factor.
I'm not sure if you are confused or just arguing for argument's sake but you mentioned that the 970 pro is rated at 3.5GB/sec, which is the same as what I mentioned, 3500MB/sec. I did not pull the number out of the air and didn't "overhear" it from you, I was speaking from experience. My 2TB 970 Evo achieves >3400MB/sec on sequential tests in my laptop, and the 970 Evo is not the newest or quickest PCIe 3.0 drive - there are now EVO plus' drives which are slightly quicker I believe and the MLC Pro series drives. You seem quite defensive and argumentative, so I assume you won't believe me, so I've googled a source for you - it is a review of the 970 Pro with a nice speed comparison with many other drives: https://www.tomshardware.com/reviews/samsung-970-pro-ssd-rev…
Also note that this review was from when the 970 Pro was first released about 2 years ago when PCIe 4.0 drives were not in the consumer market yet, so al the other drives used in the comparison are PCIe 3.0.You are right that it is extreme, but that's because Samsung are one of the best in the SSD business in terms of there NAND flash AND controller.
This has already been a bit long-winded, but I guess to summarise and reiterate my main points: NVMe m.2 drives saturate a PCIe x4 link, and PCIe 4.0 drives do offer a significant speed boost.
@navjay: I'm not sure what you meant by "moot", the limitation of M.2 only using 4 lanes of PCIe is not a limitation of PCIe 3.0. You can see that much yes? And that's exactly my point with PCIe card, you can theoretically double or quadruple a SSD read throughput with RAID card and it may not even saturate a PCIe x16 slot.
Now let's go back to the original statement that I have issues with "All Nvme drives are maxing out at PCI3.0". Do you see how dangerous that kind of generalization sounds? After reading that, a normal person will now have this assumption that if he's buying a NVMe drive, it has to go with a PCIe 4.0 system, which funnily enough Intel doesn't even sell yet. The truth is far from that, can we agree? I despite such misleading generalization because it sounds more of a marketing gimmick than actual advice. Even if we consider single M.2 drive, there're far more NVMe SSDs that's nowhere near the limit of PCIe 3.0 x4 than ones close to it.
I don't know why you suddenly pulled Samsung 970 specs and review, I'm well aware of their specs, I've built a few PCs for friends/colleagues with them. I've seen the TH review some time ago, and if you notice the Sequential Read Performance chart, you can see the 970 Pro sometimes go above that depending on QD, to me that probably indicates the controller respecting power/thermal, not PCIe 3.0 itself. Your original statement is "In the real world one would not be able to reach the theoretical limit, so 3500MB/sec is around the ceiling for PCIe 3.0 drives". I'd like to see a source for this, that's all I'm saying. I agree there's a certain overhead to PCIe throughput which I'm interested to find out. But just because the max theoretical bandwidth of one of if not the fastest SSD is 3.5 Gbps, doesn't mean that's PCIe 3.0 has a 12.5% overhead, which is what I found extreme. Again, you could be right, but I'm keen to see the source for this, or if it was just a limitation of SSD controller for PCIe 3.0.
I only have minor issue with your "NVMe m.2 drives saturate a PCIe x4 link", only some of the fastest do. I agree "PCIe 4.0 drives do offer a significant speed boost.". And again, I'm well aware (and do advocate when the use case is right) of PCIe 4.0 benefits, with twice the bandwidth for each lane, there's plenty of bandwidth to go around for my upcoming GPU, SSD and NIC.
@rookie317: By moot, I mean that your point is not important or relevant. By using a RAID card you aren't magically increasing your SSDs speed. You are using many SSDs in parallel to improve the read and write speed available to the computer.
I agree that the statement "all NVMe drives max out at PCIe 3.0" is wrong. Can you agree that "The Samsung 970 Pro, one of the top tier NVMe SSD is rated at 3.5/2.5 GBps which can't even saturate PCIe 3.0 x4" is wrong as well, or do you need to reread what I wrote above.
If you are aware of the 970 pro specs, they why did you think the 3500MB/sec throughput I mentioned earlier was wrong or overestimated?
I'm guessing you are just trolling and arguing for the sake of arguments, or just trying to rile me up, so believe what YOU want. I just think it's good for those who are new to SSDs who read your first comment to know the facts behind it so they don't just believe it.
If you are actually genuinely arguing/don't believe me, then here is my last gift for you from the first page on google for pcie overhead: https://www.xilinx.com/support/documentation/white_papers/wp…. This might also help you understand - does gigabit ethernet provide transfer speeds of 125MB/sec, or is the maximum speeds you are likely to see around 1000MB/sec?
Anyways, good luck to you and I wish you all the best for the future.
@navjay: And that would be the limitation of the SSD and/or M.2. To the system, it now has this PCIe card on its x16 slot running double or even quadruple the speed of the fastest SSD. How is that NVMe saturating PCIe 3.0?
Because you made it sound like the 970 is the proof of x4 actual maximum bandwidth. If I have to make a real world analogy, it's like you're saying Ussain Bolt 100m record is the best human can do while limited by the asphalt. All I'm saying is it could very well be, but the burden of proof is with you. And unless Samsung makes a PCIe 4.0 version with the exact same controller and NAND, I don't think you can. Designing controller is hard, there's no incentive for Samsung to beat themselves is there?
"Can you agree that "The Samsung 970 Pro, one of the top tier NVMe SSD is rated at 3.5/2.5 GBps which can't even saturate PCIe 3.0 x4" is wrong" I'm not convinced, I'm talking based entirely on the number here 3.5 Gbps < 3.94 GBps theoretical throughput. Sure there's overhead, but I find a 12.5% overhead extreme. And again, I could be wrong, there seem to be many SSDs other than the 970 Pro at or close to that 3.5 GBps. That's why I'm asking you to give me a more concrete proof that 3.5 is the actual limit of x4. Will you say the 980 Pro 6.5 is the actual maximum of 4.0 x4 also? What if I tell you Phison E18 controller is rated at 7? Will you keep changing the actual maximum every time something faster comes out?
I don't need to be educated on overhead, I'm well aware that's there's overhead to pretty much any kind of data transfer. Conveniently I just made another [comment](3.94 GB/s)[https://www.ozbargain.com.au/node/533662#comment-8631073] regarding 1GbE, oh and I think you got an extra 0 there. Again, what your article doesn't help you prove is that 3.5Gbps is the maximum actual bandwidth of 3.0 x4.
I'm doing pretty well all things considered, thanks.
Shopping express were the best back when HP Microservers were cheap
Can I put any of these in a ps4?
Yes. SSDs are slim enough but not all 2.5" HDD drives are.
Bad experience with these people. SSD I bought a month ago never arrived and it's impossible to contact them. Not answering phones and not replying emails.
I've only had a positive experience with them. Even when dealing with Warranty..
Is this seller trustworthy? What have your experiences been with them?
I've shopped with SE for many years, haven't bought anything recently, but they're great when I'm looking for specific components.
It's fine when item do arrive. If problems do occur, they ignore your emails and their call support is gone.
I tried contacting them for over a week now, nothing I can do but to go through paypal resolution centre.
Got my hopes up. I though the $165 was for the EVO
