Question 5000/2500 w/ DRAM vs 5000/4000 DRAM-less ?

[Regev]

Gonna buy a new 500gb NVMe SSD and I see these two on Amazon, both selling for the same price:

WD_BLACK 500GB SN770 (5000/4000, DRAM-less)
SABRENT 500GB Rocket (5000/2500 with DRAM)

Which one would you go for? Will DRAM give the edge when it comes to responsiveness and latency (ie, launching apps, and other short, burst actions) ?

Thanks

Always get the dram based SSD. I’m not sure I would buy either one of those I would stick to Samsung or some quality mfgr

Western digital does make some good ones just perhaps not the one you’re looking at

 

[Regev]

Does DRAM make that much of a difference in terms of latency/responsiveness?

Do not put much relevance on synthetic ssd benchmarks.
They all perform so similarly that a user can't really tell the difference..
These guys could not:

I might suspect that a 1tb drive would be a better buy if budget permits.
I would today buy only Intel or Samsung for a ssd.
They make all their own parts and can control quality better.

A wonky ssd is the last thing you want to deal with.

Sabrent isn't Intel/Samsung quality anymore ? I remember they were one of the best a few years ago .. ?

Currently I have a Gen 3 Sabrent , about 2.5 years old. (1TB; 3500;3000). I want to replace it first, because I only use about 50GB total, so it feels like such a waste having all that space (will give the drive to someone who could actually take advantage of it), and second, because I run production-work on that machine (not with big files, so bandwidth speed doesn't really make a difference), I always refresh the drives every few years, to minimize reaching their failure point

Why would you limit yourself to 500gb, when 1tb have become so cheap?

 

[geofelt]

You are likely to see new product infant mortality before your current ssd fails.
Just keep an external backup if thee is anything on the ssd that you value

Always go with DRAM, no DRAM means they can actually be slower than hard drives when doing things like downloading or moving large files

Still, in this day and age? I thought they found ways around it

Cause I only use 50GB

Good point. What % of new drives die early?
Guess I'll just keep the Gen3 1TB that I have.

Not really. They have no buffer which means they slow down quickly and generally because the controllers are worse they’re less efficient with space and slower anyway.

In other words, you'd take a Gen 3 NVMe with DRAM over a Gen 4 without a DRAM any day ?

Depends what you’re doing. The dramless will be very slow when moving large files. It’ll be fast to start off with then bog down. Question is do you really need more than PCIE 3.0 speeds? You’re talking 4GBps so outside of Thunderbolt you’re not going to hit any speed restrictions as even the best motherboards with 10Gb lan is only 1.25GBps

 

[geofelt]

Cause I only use 50GB

Then why the urge to change??

 

[logainofhades]

The 1tb versions of those drives are typically faster than their 500gb counterparts, just as an FYI.

dram-less drives are made just for one purpose: for laptops (where every extra energy saving counts)

Unless your moving big chunks of data I doubt you will see a diff.
