This SSD does not have DRAM and not recommended for use with the PS5

  • Lower Power Use
  • Good range of capacities available (250GB to 2TB)
  • One of the best examples of an HMB technology SSD
  • All in-house components
  • Surprisingly High Writes in throughput and 4K IOPS

CONS
  • No Heatsink Equipped Version
  • Not built for sustained use
  • No onboard Encryption

Do PS5 consoles support Host Memory Buffer?
No. Some M.2 SSD devices may support Host Memory Buffer (HMB) but they may experience slower-than-expected performance because the PS5 console does not support HMB.

For something like an SN770, it's good. But if you're looking for lowest price per TB, Kingston NV1 is $179 for the 2TB variant. It is a much inferior drive compared to the SN770. I would personally pay a bit more for the WD.

Which laptop do you have?
You would not require a PCIe 4.0 (Gen4) SSD unless it is has an Intel processor and purchased recently.

Memory Express charges $9 for shipping, so the total is the same as $229 from Amazon with free shipping. I am looking to upgrade my laptop which only supports gen 3 PCIE. Although there won't be benefits of higher performance of gen4 pcie, but hopefully this will be more future-proofed. Comparing to SN750 2TB (currently $250 at Amazon), is this SN750 2TB a better choice?

It seems both Canada computers and Amazon dropped the price to match Memory Express's price.

The WD_Black SN750 (not SE) has DRAM, so more expensive to manufacture and does not use the laptop memory as a memory buffer.

WD_Black SN770 uses HMB, will slow down when laptop memory has high utilization.

from https://nascompares.com/review/wd-black ... sd-review/

"Host Memory Buffer (HMB) architecture SSDs such as the DRAMless WD Black SN770 is by no means a perfect ideal basis of storage for prosumer and power-users. Smooth running of the SSD is not possible when the memory of the client machine is at a high % of usage. Additionally, you need to ensure that your host system supports HMB in order to ensure the drive is not going to immediately bottleneck. That is why the WD Black SN770 is fully supported on PC but PS5 storage upgrades with this SSD are not recommended, as HMB is not readily available in the close console system design. Another downfall of HMB SSDs in the eyes of power-users is that sustained/constant activity with this lack of onboard memory faces diminishing returns. So operations that are larger in scope of sustained over a longer period of time result in the memory-flushing that this smaller area on onboard memory needs to be too low in frequency for higher performance to be maintained. The result is that the high performance of these more enduring operations will slow down more and more as they continue. PC gamers will not notice in instances of gameplay when the loading of an AAA title is higher front-loaded, but content creators and editors that are editing larger projects off the SSD in video production software will notice this slowdown over time."

Absolutely Yes. WD proves that SN770 could achieve a decent performance without the Dram at a budget price, the speed should satisfy for most users. Also, it uses TLC Nand, its durability with a 1200 TBW is the same as its big brother SN850 (which costs over $300), both should last a long time. Your laptop could be a Gen3 interface, technically, you don't need a Gen4 SSD such as this SN770, the good thing is Gen4 SSD is downward compatible, so you could put a Gen4 SSD in a Gen3 slot and run at the maximum speed of the Gen3 interface. Unless you could find a cheaper Gen3 SSD with a similar performance and quality. this SN770 should work fine on Gen3 laptop or desktop.

Yummy! 5th generation BiCS NAND flash memory.
Very impressive performance. I already have the SN850 with DRam and BiCS4 so will wait for BiCS5 with DRam model.Winking Face
