WD Black SN770 1 TB

[W1zzard]

The competitively priced Western Digital WD Black SN770 achieves impressive performance results that match the more expensive Samsung 980 Pro, WD Black SN850, and Kingston KC3000. It seems WD has found a solution to overcome the limitations of DRAM-less designs—very impressive.

The 570 was impressive as well. WD is killing it.

 

[Cutechri]

What can I say, I am impressed

 

[trparky]

About time someone was able to compete with Samsung SSDs because up until now, Samsung has been at the top and have been pricing their SSDs as such. Competition is good.

 

[Cutechri]

I love how we have to repeat that competition is good just to remind the rabid fanboys of the truth.

 

[mechtech]

Interesting M.2, hopefully CAD prices aren't out there.

@W!zz
"The hottest part on the drive reached 86°C, which is quite a bit lower than the software reported temperature of 74°C. " I'm assuming that's higher?

 

[Tartaros]

Hope there won't be any switcheroo fiasco this time.+

 

[dj-electric]

WD truly killing it lately with their entries. Very nice

The boot time is since the first ssd for consumer totally useless cause many dont use fast boot

Ive saw only one point since nvme ssd are released against sata ssd,
its about unpack cracked games and ripped movies.


If the game loads in 15 seconds or 20 seconds is totaly useless.


Edit:
Nice Fact about SSD and console even Ratchet and Clank the new one is only for ps5,
but like horizon forbidden west load from menu a save game take on both:
PS5 insane SSD onboard with 675 GB usable 10,31 seconds
PS4 with Sata SSD 1TB (931GB) 12,16 seconds

Using system ram in place of onboard? a nvme feature, downside been more risky to data and higher ram usage.

Was it confirmed its not using more than 64megs of system ram?

Personally I dont want dramless ssd's as standard.

WD do seem samsungs strongest competitor right now. My comment based on the in house capability.

I would guess not good enough for PS5 upgrade?

 

[Zareek]

Impressive but can you trust WD to not pull some shenanigans with parts and things of that nature? What are they hiding? I just don't trust them. Ever since the WD Red fiasco, they've continued to give everyone reasons to doubt them.

Been looking for a nice 2TB nvme drive to upgrade the ol' desktop and am surprised at the pricing for top end 980 Pro and SN850 (huge premium for the heatsink version of the 850).

Maybe the solution is grab a 770 and just upgrade down the line a little sooner than originally expected?

Thanks for the review, W1z!

“—very impressive.”
Project Farm come to mind for anyone else?

What happened with WD? I'm guessing that some models, if not most of them, are SMR!

 

[Mussels]

Just a genuinely solid product it seems

I gotta know where you got that idea from

 

[Assimilator]

Impressive, but I'm still not sold on WD due to the bait-and-switch they pulled with the WD Blue/SN550 drives.

Also, what is it with NVMe drives topping out at 2TB? The only company that's gone higher is Sabrent AFAIK. We need more storage in smaller footprints so SATA can finally die for good.

 

[thewan]

no magic happening here again. the sn770 1tb is ~210 USD. The KC3000 1TB is still the cheapest of the bunch, with its price continues to stay ~175 USD despite ongoing world issues (war, nand contamination, etc)

 

[Anymal]

Some kind of sorcery, W1zzard!

any ideas on how this would perform on pci-e gen 3? looking to upgrade my 250gb nvme but i dont have a gen 4 motherboard, but this would be handy for a future upgrade, if it still performs well on gen 3.

Random 4k performance, the one that matters, will be significantly better on PCIe 3.0, speaking from experience. I have a 4.0 slot on my board but I keep my 980 Pro on a 3.0

Your own link covers it right at the top

any bench going above 3.5GB/s or so will get capped there - sustained performance may be better, since the cache and temps wont hit their limits as fast

Anything under those limits (like random read/write) will perform exactly the same

 

[bug]

a DRAM-less value-oriented SSD design with support for PCI-Express 4.0, but lacking a DRAM cache

@W1zzard And that's in stark contrast with other DRAM-less drives that do not lack a DRAM cache. Right?

Same, got a 980 PRO on 3.0, the only benefit of 4.0 is a little higher sequential read which isnt very important,

That is interesting as well that you have tested and noticed 3.0 has better 4k.

Can't tell if this is sarcasm or not? Seems like I keep hearing everyone frothing at the mouth for the SN850 w/heatsink for their PS5s. I've been having trouble finding any references to whether or not it's useful at all in a desktop environment.
