That’s more than DDR4 Ram bandwidth. Whoa!
I just want bigger drives… I feel like we’ve been stuck at 1TB for at least a decade.
You can get spinning rust all the way up to 32 TB in a single 3.5" disk and 8 TB in an NVMe drive. The tech is out there, but it takes time for the price of stuff like that to come down when there isnt much demand for it.
SSDs have gotten much cheaper. 10 years ago, they were over $0.50/GB, now they’re just over $0.04/GB That’s over 12 times cheaper.
You can get a 2tb ssd for $85. 10 years ago a 2tb ssd would’ve been super expensive and very boogie.
When do we start needing active coolers for our drives?
i have a samsung 2.5" ssd and it actually would benefit from active cooling. when i installed my os, downloaded my steam games, and then made a copy of one (because steam insists on updating which breaks mods) and noticed that write speed was slow af…so i tested with kdiskmark and all speeds were exactly at 75mb/s while they should be at like 550. it throttled to keep temperature under 60c.
Enterprise NVMe drives have some active cooling, but it’s mostly due to high density
Now.
It wasn’t that long ago when RAM had similar transfer speeds.
With PCIe 6, consumer grade SSDs shouldn’t need more than a single lane. That will be nice since AMD and Intel have been pretty skimpy with the PCIe lanes lately.
What about latency though?
The latency of RAM has been around 10ns for the last couple decades. The latency of a good NVMe SSD is about 1000 times worse than RAM.
I wonder if we reach to the point we’re RAM would be unnecessary.
27GB/s is faster than DDR4 RAM.
Just wait until they come out with DDR4 SAM.
