Are D-RAMless ssd's fine?

[MitsoMinh]

Im currently getting my pc parts for a new build with a budget of around 650 Euros. My current build ( https://pcpartpicker.com/list/Q7fKbL ) is just above that number, but my concern is if that SSD would suffice for at least 4-5 years of use. Would it be wise to spend another extra 40 bucks and buy something like a 980 pro? I've heard bad things about D-RAMless SSD's and I'm wondering if I should bite the bullet and use that NV2 or spend the extra 40. I'm also buying a monitor for around 150, hence why my budget is super tight. I plan on gaming on my pc and doing some editing. I live in Greece, and the prices are almost the same.

With an NVMe drive, it can borrow a few MB from your ram to use as cache. I've used some real cheap DRAM-less SSDs and they work just fine.

DRAMless SSDs are alright for your average desktop, but that particular drive is not great quality (prone to part switching, likely to be QLC, only a 3 year warranty and has poor endurance rating that is half of a guaranteed TLC drive like the SN570 or SN580).

Yes, for normal gaming desktops. Back in the SATA days you really wanted to avoid them but with modern NVMe and HMB (Host Memory Buffer) its not a concern for most people anymore. If you had a workload where it might be a concern, you'd know. 

 

I have two WD SN770's in my system and they're fantastic.

I was actually deciding between the NV2 and the SN580, the latter is 5 euros more. Now that you've told me about the endurance rating I'll go with the SN580, thank you.

I'll make it easy, the NV2 is a trash SSD so ignore it completely.

Yeah, I had a feeling it was a bit trash after I read some complaints about it's performance

Not only that its is SLOW but also has very low tbw (terrabytes to be written aka how much it can write before it dies) and people have had these dying on them within a year for people that have more than some light use(so even with light use dont expect a long life)

 

I suggest you look at a crucial p3/p3 plus too as an option

Storage is a great thing to cut corners on when you have a tight budget. You can always upgrade it later, or just add to it. At least when talking about gaming PCs which are presumably not storing anything truly important.

Within a year is crazy, thank god i decided to do this post, I would've gotten the NV2. And thank you for the suggestion

P3 and p3 plus are on Phison E21T (4-channel, DRAMless) + 176l QLC micron ( it’s slow NAND outside of it’s pSLC mode, and low TBW ). 

SN580 is identical to SN770 in hardwear, Polaris MP16+ (4-channel, DRAMless) + 112l TLC Kioxia. 

 

I would go SN580 every time. 
 

as for the question. Dram do matter, just that in normal PC use, you use SSD so light, that it’s not very noticeable.

 

 

and also remember, there are some good DRAMless like sn770 on TLC etc, and then you have bad one, like NV2 on QLC etc, 

 

HBM usually only have 32-64MB of space reserved, and that can store FTL for 32-64GB of disk space. 
any old data read, is done with latency penalty, as it’s going to FTL from NAND, instead of copy fragment of FTL in host RAM. 
HBM is usually good to boost couple GB of writes, and fresh data reads, to some GB limit, usually all you need to fool benchmarks, but usually also all you need for light PC use.

If the SN580 and the SN770 are identical in hardware, what makes the SN770 more expensive? The colour?

Firmware that do not make the performance drop, it's expensive to have that in SN770 

Like look on the Crucial P3 and P3 plus, it's also the same hardwear, they just locked P3 to PCIE 3.0 in firmware, and sell it cheaper. 
As it's cheaper to produce one, and sell as two models.
