The load times in the games may have been so different because there might have been a lot of smaller files. A lot of drives do slow down a lot when there are a lot of small files and they generally work better on one larger file that is the same size as what all the small ones take up. Maybe it is partly because when writing them the computer has to make an entry for where each file is stored rather than just make one.

Good stuff, in your benchmark suite for SSDs you should consider adding 2 things, performance when writing to a full drive, and performance when you fill the '"cache" on the drives. QLC should be the obvious choice for the mast majority of users, it's cheaper and just as fast as drives with TLC and DRAM for general use, which is, reading data.

So basically, don't spend the extra money on DRAM cache unless you are doing very large file writes

If you use the ssd for external. The one with Dram will increase the TBW

@@syarifairlangga4608 i have a 2tb SSD rated for 1600 TBW with no dram. I don't imagine the DRAM equivalent will be that much higher, and even so i will never get to that amount

@malvinchau2056 3 ай бұрын

@@bassgoul You're right about that. dram works as a buffer to allow (larger) file transfer to be faster and more efficient, but it doesn't matter and won't actually increase TBW. This is because while it is more efficient, it doesn't increase TBW because the files are still the same size regardless of efficiency lol.

@@malvinchau2056 I believe @syarifairlangga4608 meant that English is not his first language. He's actually saying that DRAM doesn't directly increase a drive's TBW. What he likely meant is that using a DRAM-less NVMe SSD as external storage can halve its advertised TBW lifespan. In this case, the Pinnacle SD-1 would only have a TBW of 1000

I have a question that I can't find: does DRAM produce more heat onboard? There maybe converse logic in this, a larger cache buffer will reach advertised bandwidth, therefore less prolonged heat since you get the job done fast. Alternatively, dram is yet another higher voltage rentention than slc host memory buffer, therefore more heat. I'm curious about it. I feel dram-less is fine for laptops, but you never know with extended use. I just read that dram can pose a problem if the chip is higher than the storage, heat spreaders and sinks may not reach all of the chips evenly. techpowerup is pretty good in their reviews, pics, thermal images, but it is a burning question. No pun intended.

@Matlockization 2 ай бұрын

Dram-less would not be good for laptops as it runs a lot hotter.

@greycell2442 2 ай бұрын

@@Matlockization Well, after reading Samsung findings, it's obvious that dram keeps heat down at same spec comparison. Increasing bandwidth, however, increases speed and heat, regardless. I did find that it is difficult to get dimensions on dram chips, which by certain mfrs, prevent a heat sink solution from full contact on the nand chips. The truth is, many, if not most laptops come with dram-less. Not that I care, but if a customer wanted it to come with Win11, there's that problem. So, but the nvme 5, and soon, nvme 6 is what people are talking about now. It's not easy digging for particular non-advertised details. I have a Corsair mp600 dramless on my laptop. It's fine. It's hot, but I don't play games or render 3d on it. If it were QLC it would be horrible. I don't know why QLC is even produced, it uses so much power.

@greycell2442 2 ай бұрын

I should say bottlenecks are real though. If you put a nvme 4 on pcie 1.3, bandwidth bottleneck, so more reads/writes to achieve the same thing. I'm sure people have done this on older boards, realizing the heat. I could guess at that. That's why I'm curious about the newer than new published nvme 6 specs.

@Matlockization 2 ай бұрын

@@greycell2442 You might be right about the QLC, but same read/write speeds is something I've always gone for regardless and that inc's dram and more of it on an M.2.

@greycell2442 2 ай бұрын

@@Matlockization The theory goes: QLC is an extra voltage node, more power req thus more heat buildup over runtime. Enterprise uses SLC for a reason. More importantly, because of this, QLC significantly drops the life of the drive. I had to dig for longevity. A non-gamer, non-graphics/person will see good lifespan, but if you were to run a linux server, say a database using lvm containers, continuous access to that container will shorten life. A lot of fuzzy logic on estimates, say -25% on QLC compared to TLC. Under 1TB or virtual containers shorten lifespan as well, simply because you are statistically increasing access in a smaller space. I thought purchasing ram would be difficult for a consumer. I think gamers would be disappointed in QLC if they never did a backup. Gen5 QLC, I would sue the mfr for biligerance.
