    This or Kingston kc3000?

      Kingston is better, faster and has more dram. Plus you can get it from local stores at a good price where warranty from this might be a pain as you might not be able to do with western digital

        this is just as good as the KC3000 and is priced similarly to this deal:

            @[Deactivated]: Yeah, the comment seems fine. I am guessing.

            • He probably should reply to Modesty, since Wicko was merely answering the question asked.
            • Innogrit IG5236 based SSDs, they don't seem very popular. So some people might not quite agree with "just as good". Part of the issue is based on the reviews, those SSDs tend to use a slightly older gen of NAND.

            It's OZB, the votes don't have to make sense.

                @joomax: It seems like a good deal at the moment. However, the 2TB and 1TB (actually all) SSDs are having price changes left, right and centre. Cheap ones are attractive, flagship ones are attractive.

        You think warranty from a local ship is better than Amazon's? 😂

        • netsurfer on 22/05/2023 - 13:31

          Depends on the store. Example, for one store, I got a full refund after 4 years. Raised the request online, got approval, drove to the store, got full refund.

          Another one took a lot longer. Contacted the store, staff actually suggested I get full refund. However, they had to send the SSD back to the distributor's RMA department to get it processed. Won't give me full refund on the spot. Waited about 3 weeks.

          Problem is, I am really worried about ones I bought from feeBay from Interstate sellers AND another retailer I started using which I've been told that they only provide store credit.

      For 1TB version, KC3000 (actually all flagship PCIe gen 4 x4 1TB SSDs) cannot run take full advantage 8 channels, so SN770 1TB is neck and neck with it.

      At 2TB, the table turned. Performance wise, KC3000 2TB is better. However, how many of us can actually properly utilise KC3000 (or even SN770)?

    • nguyenlucky on 24/05/2023 - 11:21

      kc3000 is comparable to sn850(x). It has DRAM. SN770 does not.

      Below the Sony recommended minimum sequential read speed of 5500MB/s but people seem to be using it without issues, at least so far.

        These minimum speeds are ridiculous. It wasn't that long ago that hard disk read speeds were 50MB/s.

    • netsurfer on 22/05/2023 - 12:35

      Officially no (because it is below the recommended spec), unofficially, yes (works and PS5 allows it).

    • Cyb3rGlitch on 22/05/2023 - 12:59

      I wouldn't do it. It "works" but as developers push the system to its limits later in the cycle you may run into problems. Remember assets are being streamed from the SSD in real-time, hence the crazy minimum requirement.

      • netsurfer on 22/05/2023 - 13:38

        Nah, in majority of cases, developers won't do direct streaming from SSD. There are two main issues with that. Hardware compression is normally used so the devs need to keep that in mind. Secondly, developers prefer to use RAM. Sequential read on SSD is all hyped up. SSD latency cannot compare to RAM.

        The easiest way to think about it is this. Would you have a PC with just 4GB of RAM and get the fastest PCIe gen 4 x4 SSD and run virtual memory like crazy? The truth is, if given a choice, a dev would take RAM over SSD every time.

        If a high end PCIe gen 4 x4 SSD is so amazing (or the PS5 internal SSD is so amazing), why do most PS5 games still have load screens?

        Think about The Last of Us Part 1 PC port, eating VRAM like crazy issue, you cannot fix that with the fastest PCIe gen 4 x4 SSD.

        • Cyb3rGlitch on 22/05/2023 - 18:31

          If you're interested in how the PS5 utilises the SSD, this video from their system architect explains it in detail. Skip to 12:14 (or 21:16 to go direct to expandability). https://youtu.be/ph8LyNIT9sg

          • netsurfer on 22/05/2023 - 22:50

            @Cyb3rGlitch: First, you do know you can provide a youTube link with a particular point of time in that video right?

            Have a look at that video at 12:37, that picture. It is like the last gen, except SSD is now on the right hand side. Think about that, the data still needs to go to RAM. Now, as a game developer, would you write a program that magically count certain seconds and if the SSD is too slow, just crash? In reality, the game developer will just let the RAM loading completes before continue with the game.

            Ratchet & Clank: Rift Apart works fine on NV2, which is really more like a PCIe gen 3 x4 SSD. If you actually do coding, you will know SSD is still too slow compared to RAM. Also, here are the things you don't realise:

            • Developers dislike reading from SSD or disk all the time. It's annoying slow compared to RAM.
            • Most of the hard work in game development are all done with VRAM and RAM.
            • People will think you are nuts if you spend a lot of time writing a game reading from SSD all the time.
            • Cyb3rGlitch on 22/05/2023 - 23:02
              +1

              @netsurfer: No need to be condescending mate, that talk explained the source of the requirements pretty clearly. The streaming into RAM is abstracted away from the developer, and they are probably using a dev kit for testing that is to spec, not random variations of external SSDs. It might be fine to use a lower spec SSD, but you may run into trouble later. Nobody knows for sure, that's why minimum specifications exist.

              • netsurfer on 22/05/2023 - 23:20

                @Cyb3rGlitch: For PS5, honestly, I still would like Sony to implement Quick Resume like Series S|X. That, fundamentally, shows that PS5's internal SSD is not that fast (nor PCIe gen 4 x4).

                PS5's internal SSD is 825GB. Currently, with 8 channels setup, one really needs 2TB to flood that bandwidth properly. So anything under 2TB cannot possibly be 100% utilising the whole bandwidth. That's why you see SN770 doing well in 1TB (giving PCIe gen 4 x4 flagship SSDs a hard time because those cannot flex their muscles until 2TB). The NAND flash for PS5's internal SSD is basically SN530 grade. Sure the custom flash controller design helps (and we know there are a lot of PCIe gen 4 x4 SSDs which are basically fast in reads due to its controller, rather than superior NAND.

                PS5's original NVMe SSD test was a joke. Sony went for 0-Fill read test, which ALL Phison PCIe gen 4 x4 SSDs cheated like crazy. If you run NV2 Phison E21 version of SSD with 0-Fill test, it will get close to required speed (may even exceed). A lot of Phison E16 SSDs claimed to be PS5 ready as a result. Also, how did Samsung tweaked its firmware for 980 Pro to address slow test result after Sony patched it?

                The high queue depth / high thread count read test is gimmicky. The "streaming" cannot be 16 threads. If it is Q1T1, then PS5 internal SSD and 1TB PCIe gen 4 x4 SSDs will easily drop below the "recommended" requirement.

                @Cyb3rGlitch:

                The streaming into RAM is abstracted away from the developer

                The API / Dev Kit still needs to let the program / developer knows the progress of the streaming or at least it finishes. If the developer has no idea about the streaming whatsoever, how does the dev know PS5 internal SSD has finished streaming the data to RAM?

                You cannot go, PS5, stream this world to the RAM, and I don't care whether the streaming finishes or not, let the character start moving.

                Would you play a game where you fast travel to a new world or new location every second? Even if your answer is yes, then we are back to the question why can't PS5 with its "magical" SSD, let me swap games every second without delay? There is so much more than just send data from SSD to RAM.

              • netsurfer on 23/05/2023 - 00:56
                -1

                @Cyb3rGlitch: PS5 games still have load screens because as I mentioned before, game devs won't go full on SSD during actual game play because even targeting 30fps requires RAM.

                The loading screen time is variable, even for the internal SSD. When you play games, you move randomly, so RAM is required. Being 10X faster than SSD in random read, with much lower latency, RAM and VRAM matters.

                Ask yourself this question, why does EVERY program you use on a PC use RAM? Even Notepad uses RAM.

                RAM latency is measured in nanoseconds, whereas SSD latency is measured in microseconds. We are talking about 1000X difference in terms of latency. With RAM, I can swap things 1000 times faster than SSD. As a game dev, I have to use RAM for real time game play, even if the PS5 owner is dodgy and uses an SSD storage that's 2X slower. I will penalise that user with a slightly longer load screen, but there is no way I am willing to bank on SSD which has 1000 times the latency of RAM for the actual game play. Really hope that can sink in.

    • flagsarefun on 23/05/2023 - 12:30

      I have one in a PS5 and it works, but Sony specifically notes that drives that use HMB like this one may face performance loss as the PS5's operating system doesn't support it. Better to get the KC3000 or something like it which has DRAM

    • giordan0 on 24/05/2023 - 11:47

      I used to use this drive for my PS5, had no real issues but I've since upgraded to the faster SN850X.

    Plenty of ghetto PS5 setups using the bottom tier Kingston NV2 Gen 4 drive without any issues

    That has 3500 MB/s sequential read - well below the Sony spec - and it works fine

    If and when Sony applies a hard requirement on read speeds, just swap out the old drive to use in a PC/laptop/enclosure

    Then buy one of the 4TB Gen 4 TLC drives @ AU$400 that will be available because a flood of InnoGrit/Maxo/Yangtze Memory drives that can't be sold in the US are coming to these shores very soon

    • netsurfer on 22/05/2023 - 15:07

      Um… not quite, we are OZBers. If Maxo/YMTC 1TB is already $79 here, 4TB needs to be $316 or lower. We want bargain deals, especially if US blocks them (which I really doubt will happen, considering how many Amazon USA listings with YMTC based NAND SSDs).

      We want mates rate. PCIe gen 3 x4 4TB OZB record is $229, but that's QLC though.
