Would having no DRAM affect only write speeds or would it affect read speeds too?

Also would it affect sequential reads too or only random reads?

I may be off base here, but how do you benchmark a system with no RAM in it?

I, believe, he is asking in reference to SSDs; because, all of his other threads have been about SSDs.

Quote from this article ---> DRAM or DRAM-less SSD? What’s the Difference?
Solid State Drives are a great way to boost your PC’s performance. Unfortunately, they’re not all created equal. One of the biggest differences between all of the different solid state drives on the market is whether it has DRAM.

I prefer to have DRAM on my SSD devices so it can buffer the input and output as well as handle any internal needs.
My Samsung 980 PRO 2TB has DDR4 with the controller which is why the unit delivers screaming fast boot times

It affects both. having said that an SLC cache is probably a much bigger deal today!

Oh ok. I’m thinking about getting a budget SSD. It’s SATA III has no DRAM but can hit advertised speeds of 520 MB/s. But my system locks it to SATA II speeds. I’ve seen SATA II systems get about 240-270 MB/s with this drive. Would it still be faster for gaming than your stock run of the mill 100 MB/s HDD? I play a lot of open world games like Red Dead Redemption 2 which needs to frequently go to the storage unit for assets.

It'd certainly be faster than an HDD. I suggest getting one with a dram cache though, without dram the write speeds tank once the drive get's cluttered up.
My old cache-less Corsair LS 120GB get's about 500mb/s read but only 70mb/s write @ 67% capacity.

So read speeds are pretty much unaffected?

So your system only runs SATA II? Then you're worrying too much
