Samsung 990 PRO NVMe M.2 SSD, 4 TB, PCIe 4.0, 7,450 MB/s Read, 6,900 MB/s Write.
Decent deal til black friday rolls around.
CamelCamelCamel.
Do nvme connected to external case run at same speed btw?
Pretty much never.
You have to go really high end, such as thunderbolt external docks, to even get close to the speeds of it being installed internally.
Certain brands are notorious with their heat issues too, because sticking a heatsink on top is the solution apparently.
PCIE5 is worse, it's even hotter.
Nuts.
Speaking from my experience with a USB 3.2 Gen 2x2 enclosure, from my CrystalDiskMark tests, an NVMe inside an enclosure is considerably slower than an internal NVMe (less than half the sequential throughput). This is obvious though - with USB 3.2 Gen 2x2 only has 20 Gbps of bandwidth whereas PCIe Gen 4 has ~64 Gbps.
But comparing random IOPS and latency, an enclosed NVMe performs even worse than a SATA SSD. It is one of the reasons why I added an eSATA bracket to my desktop computers, so I could use SATA SSDs as though they are external SSDs (while keeping the same performance of internal SATA). Enclosed NVMe still beats SATA SSD on sequential throughput.
I am not sure if this applies to Thunderbolt or USB4 enclosures though, because (some?) do PCIe tunneling instead of translating the data into USB data packets, which may reduce a lot of the overhead and latency.
Yes, the random read/write does suffer quite a lot in an enclosure. Sequential speed for USB 3.2 gen 2x2 maximum is 2500MB/s (but you need to factor in protocol conversion so probably at best 2300MB/s, but I normally expect ~2000MB/s).
USB gen2x2 on PC, using a PCIe gen 3 x4 SSD - No point using PCIe gen 4 x4 SSD with such enclosure.
USB4 on Mac M1 Pro - FYI, PC results would be slightly higher than this.
Same SSD on m.2/NVMe PCIe gen 4x4 mode
Strangely, on a Mac, high queue depth 4K random read is decent, but that's not a common usage scenario.
Amazon operates in Australia and by ACL they are obligated to provide Warranty to consumers. Therefore as per manufacturer states, this comes with a 5 year warranty.
https://business.gov.au/legal/fair-trading/australian-consum…
Only for up to 2 years though right? After that you are required to go directly to samsung.
No, as per ACL. A business operating in Australia is responsible for providing warranty to consumers.

2. Consumer guarantees – snapshot
"Most of the guarantees are given to you by the seller or service provider; in some cases they are given
by the manufacturer. If the manufacturer doesn’t have an office in Australia, then the importer is
responsible for meeting the manufacturer’s guarantees to you."
Amazon is responsible for providing the 5 year warranty that the manufacturer - Samsung has set out for this product. If Amazon refuses to comply they are entering unlawful waters considering they are operating a business under Australia.
@dfg555: Interesting, so a while ago I RMA'd a drive and couldn't do it through Amazon (option not available). Legally I could have pushed them to deal with it on their end?
@Wicko: You didn't chat with an Agent? Amazon agents have helped me a number of times on my purchases from Amazon US or other Amazon branches.
@Wicko: In short, correct. MSY has been fined millions, and millions, for trying to pretend it becomes "your problem" and fob you off to manufacturers.
@Ademos: Which I always found funny cause it's never happened to me and I've been shopping with them since their first cramped store in Auburn. Not saying they didn't do that, because I 100% can see it. I found they were generally fine if you knew what you were there to get. Then again I look like one of the staff so maybe that had something to do with it…
I think so too, but interesting hook:
"When purchasing International Products, you acknowledge that the sale occurs outside of Australia and that you are importing the products for your personal use…"
https://www.amazon.com.au/gp/help/customer/display.html?node…
So this almost reads like Amazon AU is only a conduit for my personal purchase that I make outside of Australia with no ACL?
I bought one earlier today and I believe I have a full warranty through Amazon AU. But I ain no luya.
I don't think this has any implications at all. Regardless, Australian Consumer Guarantees override whatever the Business states. Any business operating in Australia overseas or not cannot overrule Consumer Guarantees.
https://www.accc.gov.au/consumers/buying-products-and-servic…
"Businesses can’t take away a consumer's rights
The basic rights covered by consumer guarantees can’t be taken away by anything a business says or does."
We're running into a similar situation with Steam before ACCC forced their hands back in 2015. Steam operates outside Australia, but that doesn't matter they are running a business in Australia, they MUST follow the ACL regardless of what their own T&C states.
@Shakow: It doesn't matter. ACL applies to any business selling into Australia regardless, and the payment is processed by Amazon Au from memory.
and by ACL they are obligated to provide Warranty to consumers
However they do not need to provide the manufacturer warranty.
Warranty under the ACL is a different thing
Anything you buy from Amazon has an Australian warranty.
Yes, an Australian statutory warranty, not a foreign manufacturer warranty.
I could not give less of a (profanity) what warranty it is, the end result is exactly the same. I'm also replying to a comment saying "no au warranty", which is factually incorrect.
@Ademos: Sure, saying there's no AU warranty is incorrect, but so is saying the AU warranty is the same as the US warranty.
@McFly: With all due respect, get lost. Nobody made either of the points of pedantry that you're now literally inventing in order to have an argument over. Jog on.
@McFly: You're now blocked. You'll say something again to try and save face in front of your imaginary audience but I, personally, don't care and won't ever see it. Enjoy your life, champ.
Samsung Australia won't provide coverage….
waiting for PCIe 5.0 M.2 NVMe SSD to hit similar prices…
Why would you even want PCIe 5.0?
Because recent and current gen Intel and AMD motherboards support PCIe gen 5, so a lot of people are not able to take advantage of it.
Also, technically, the NAND chips used in this Samsung 4TB SSD are capable of supporting PCIe gen 5, it's just the controller isn't able to support it.
There's no need for it at all. It's meaningless.
@McFly: And the people with those usecases wouldn't be around Ozbargain anyways, they'd be purchasing B2B.
Well, most people don't need PCIe gen 4 x4 SSDs, but we still get them.
SSD makers have been putting NAND chips designed for PCIe gen 5 on PCIe gen 4 x4 SSDs because there is insufficient demand for PCIe gen 5 SSDs at the moment. Furthermore, the current generation of PCIe gen 5 SSDs isn't able to fully saturate PCIe gen 5 x4 bandwidth yet. So once the second gen ones come out, there is a good chance of a fire sale on those first gen.
Realistically though, considering OZBers are buying RTX 5070Ti and RX 9070XT, even PCIe gen 5 x4 SSDs aren't that expensive. They can still be useful for people doing a lot of video work. However, I think the main reason people are not getting them is due to they are only first gen PCIe gen 5 x4 SSDs. The sequential read/write need to be arond 14,000-15,000 before most people will really consider them.
4TB for $400+ already?
I miss deal like these… :(

Those are NM790, the equivalent to a 990 Evo, but bargain basement.
Can't find anything specific on (Samsung) international warranty.
I can't believe the issue of Amazon (non-Australia) and warranty has not been well covered either by Amazon or people (here) who have bought from Amazon US already.
And Amazon not mentioning any kind of warranty period on this item, whether it's local or international is ridiculous in the first place.
This is the closest it gets:
Manufacturer warranties may not apply in Australia and manufacturer service options may not be available in Australia.
Found this here on OzB: https://www.ozbargain.com.au/node/446883:
So please be aware that any product bought on Amazon.com.au from US Amazon will be regarded as it was sold on Amazon.com. You have no local, Australian warranty on those products.
Found this on Amazon from a customer perspective:
Q: Hi,is the warranty recognized by samsung sg even though we can register successfully?
A: When I called Samsung Singapore, they said that based on the serial number the product was sold in the US and they do not cover warranty - must send back to US for warranty coverage. Does not matter whether you register or not (I did not) or that you bought through Amazon SG.
So much for Samsung being a global company! So be careful where the product comes from - if shipped from the US, then no coverage from Samsung SG.
Anyway, as far as I can tell, there is no Samsung international warranty on storage devices;
https://www.samsung.com/uk/support/warranty/#products
International Warranty (Mobile products - Smartphones, Tablets, Wearable Devices)
International Warranty (Note PC Only)
https://semiconductor.samsung.com/consumer-storage/support/w…
https://images.samsung.com/is/content/samsung/assets/au/supp…
Except where an International Product Warranty has been provided with your Samsung product, warranty service will only be provided in the specific country where the Samsung product was originally purchased. For example, if you have purchased the Samsung product within Australia, warranty service will be limited to Australia only.
That last line comes back to the seemingly grey area of where Amazon US products purchased on amazon.com.au are actually purchased from. Again, can't believe this is isn't well trodden territory…
I was notified, then checked. Price has gone up to $451.54, so I have expired the deal.
Terrible price for a international grey import plus no au warranty
