WD Black SN770 1 TB

[Thorsthimble]

I'm getting similar numbers on the one I just picked up for my laptop. If I'm being honest, I didn't research it much and had no idea it was DRAMless. I only realized that fact after I got it in my hands and noticed the distinct lack of chips on the PCB. Fortunately, I wasn't disappointed by my moment of stupidity. I'm quite happy with it, especially at the price I paid for it.

Told you folks that WD's acquisition of Sandisk was a good thing - they have good flash, but just needed that top-tier custom chipset dev dollars!

Let us know if you encounter any stalls, hangs or similar during daily usage

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.

And (at least) ADATA with the S40G and SX8100, Corsair with the MP400 (up to 8TB), MP510, MP600 x, and Kingston KC3000. All available in our home country as well

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)

Where did you find it for $210? I've only seen it for $130...

Maybe he's looking at a smaller foreign country's market.
$115 on Amz US: https://www.amazon.com/WD_BLACK-SN770-Internal-Gaming-Solid/dp/B09QV692XY/
€140 on various European stores, € 166 on Amz DE

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

Sabrent seems to be the only company willing to use higher density NAND to make big drives.

That's why I have one of their 4TB rocket 4 plus drives. I think corsair was going to make a 4TB NVMe drive at some point, but no one else is bothering. It's annoying.

I don't imagine that there's a lot of people who need that size of SSD, so they've got gone after that segment of the market. They know their market and they cater to it.

Also the small fact that going from 2 > 4 > 8 TB NVMe ssd's can be quite expensive in my own country of gougelandastan (New Zealand) goig from 1TB to 2TB NVMe ssd can more often than not cost me more than twice what the 1TB SSD was, the 1TB WD SN850 Black with/out heatsink is currently $399.00 gougelandastani Plunkett's vs 2TB WD Black for well over $800 Gougelandastani Plunkett's

even though an NVMe SSD is way more simplistic to manufacture than an HDD ssd prices still far out strip those of HDD's at comarable sizes

 

[Mussels]

There comes a point where they cant add more NAND chips to a design, as well.


If they have chips with more density, they can slap those in and bam - bigger product... but without that option, the design needs to be re-jiggered to add twice as many flash memory modules and that's a new product design entirely

I ended up picking up a 2TB model. What really surprised me is considering this is the largest size they offer, it feels incredibly basic in the hand. I think the sticker really makes you feel like more is going on, so I've edited this photo from W1z's review to illustrate my point. Holding it for the first time, I quickly wondered what the heck I paid so much for. It just felt like a cheap clone of a real drive, I guess because there's no DRAM chip.

Blue = does something and Red = flat PCB that does nothing

My current drives are two Samsung 950 Pro 256GB in RAID0 (a bad idea). I'll be limited somewhat on the PCIe Gen 3 slots but whatever. I'll report back once I figure out how I'm going to migrate over to the new SN770. I've put a generic cooler on it immediately, I heard rumors it gets warm. Will see.

Have you ever seen the inside of a USB stick? Flash devices are that simple. Their closest relative is a RAM stick, after all.

That's why NVME comes in a few sizes - the reviewed one here is the common 2280

I suppose it could be used to keep hot components apart further, or to re-use an existing design where possible (If they design it well, the same PCB could be used for multiple SSD designs at no extra cost)

Oh yeah, definitely familiar with the different M.2 sizes. My immediate thought was "Why don't they offer this in a 2230?"
Heat would definitely be a consideration though, yeah.

Micron actually have you covered there, with 2TB PCI-E 4.0 NVME 2230 NVME's
2400 | Micron Technologies, Inc.

Give it a generation or two, and they'll start swapping the longer slots for dual smaller slots imo.

Topic title needs correction, M.2 description should be added.
I were confused thinking that this was a topic for SATA HDD WD Black.

Why? the SN770 model name is pretty specific

Look who you're replying to. He always knows better than everyone else
Notice how he's not suggesting or asking for a title change. He demands it.

Your 7-year-old is almost certainly more coherent than that particular forum member.

Ha LOL you're only halfway to trouble

What kind of software is used for Fill whole disk test? AIDA64, HDTune or may there is something free?

Hi @W1zzard I have a question about the SN770 in particular, how does it score so high in RND4k Q1T1 read scores?

I did not realize RND4k Q1T1 read scores were getting so high, in the high 70's and 80's, and the 512gb SN770 scores 93... wow. That is the most important score for real world usage too isn't it when people are talking about random 4k stuff never improving?

I am surprised to the SN770 score so high in that area, it doesn't have dram. Is dram on storage only good for people who copy lots of files or something?

@RandallFlagg hope you don't mind me using your post from the crystaldisk thread to ask this question, I was just very impressed by those numbers!!! the SN770 is on sale for $49 right now. even high end SN850X doesn't score that high RND4k Q1T1 read score... and isn't that the most important score for your casual/gamer user?

 

[W1zzard]

how

Probably one of WD's best-kept secrets

and isn't that the most important score for your casual/gamer user?

correct

That's probably also why it scores so high in our real-life tests
