  PC Byte also still has stock for $189 + delivery ($10?) or free C&C: https://www.ozbargain.com.au/node/764215

    Good find, but their current handling time after payment approval is up to 7 - 10 days, if you want faster delivery, i think this is a better deal

  • 

    Mojoman on 25/03/2023 - 17:32

    They do too, didn't see that.

    Did notice tho it says up to 7-10 days handling time after payment and it says Sold out in all stores with stock only for online.

  850x or bust

  Cancelled my P5 Plus order due to insane long shipping times from Amazon USA, despite prime.

  I get to wait for another sub $210 top of the line model, but hopefully with shipping less than a full month away

    I find the shipping ETA not to be accurate. The goods are delivered much quicker :)

      Not joking it didn't even ship within a week of ordering, not good enough

  • 

    turna on 25/03/2023 - 19:43

    Your order probably would have shipped today. Mine updated about an hour ago.

  bought mine year ago, solid as.

  would these max a Gen 3 system?

    Only in sequential. For just random read and write gen 3 interface should still be good and you should get almost full benefits.

  for $198 and close proximity to everyone, most would expect delivery before dinner

    Different type of usage and different grade of NAND. SN770 performance you are seeing are essentially SLC cache performance and/or not busy usage. SN770's sustained write after SLC cache is depleted is in the same ballpark as SN570 (and SN570 2TB version technically has a slightly larger dynamic SLC cache). In long running consistency test, SN770 does suffer the same fate as all DRAMless SSDs.

    In basic general usage, SN770 is impressive, but clearly, we are continuing to let best case sequential read / write performance clouds our judgement.

  Is this better or Kensington KC3000 for PS5?

  • 

    User50301 on 25/03/2023 - 21:19

    Kingston KC3000 is better for PS5 as it exceeds Sony's minimum recommended speed of 5,500mb.

  Where do you find out an SSD is dramless?

  • 

    Shaolinking on 25/03/2023 - 23:12

    What is dramless, why important

    •

      Dram helps drives sustain their write speeds for long periods of times, so typically dramless drives drop in speed quicker. However, dramless nvme drives implement a technology called HMB which allows them to use system memory allowing them to get closer to dram sustainability whilst being cheaper. In general, unless you are writing huge files (i.e. video editing or rendering sort of stuff) dramless is fine.

        No, the sustained write speed for large files doesn't need large DRAM. The DRAM is used mostly as a file location table. The sustained write speed for large files has more to do with the NAND type itself. Furthermore, it is not as clear cut. Sure, the DRAM SSDs "generally" have better NAND so sustained write after SLC cache is depleted is generally better. Latest gen DRAMless SSDs have more aggressive SLC cache. So, it comes down to how much data you write in one hit. SN570 2TB has a 900GB dynamic SLC cache when the SSD is empty. Therefore, if you only write less than 900GB in the first go, no PCIe gen 3 x4 SSD can beat its write speed (even if you have a DRAM SSD). SN770 2TB's SLC cache is pretty aggressive as well.

        Writing small files over a long period of time does show the weak side of DRAMless SSD.

          @netsurfer: Is that the same reason why QLC is generally unfavorable?

    A website such as https://versus.com/en/western-digital-wd-black-sn770-2tb will help with the pros and cons of different drives.

  Would this be a good option in an enclosure for storing photos and videos for Adobe Lightroom Classic? Or is it overkill?

    Overkill yes, but do it anyway!
