Why can't ssd be as fast as ram? Why can't we use ssd as ram?
>2020+6>I am forgotten
>>109526408>Why can't ssd be as fast as ram? Because flash memory is slow>Why can't we use ssd as ram?You can, it's called swapfile.But because it's flash memory, it has limited write cycles, and it will eventually just run out of writes
>>109526408Because it is a fundamentally different technology.May as well ask why a CD can't be as fast as RAM.
Ram is volatile so it needs to be refreshed constantly or the data is lostSSD's arent volatileYou want to place memory physically closer to the cpu for faster access and it gets bottlenecked fast with limited copper bandwidth
>>109526408u can use ram as ssd though, video editing world has been doing it for probs a decade and a half if not more
>>109526441Stupid balls animation that isn't conveying any useful information.
>>109526408I've been using RAM drives to play Skyrim before SSD's even existed. Why not make RAM dirt cheap and just forget the SSD? Just hibernate instead of shutting down, or keep some cheapo HDD as shutoff safety and run everything on RAM
>>109526511>Why not make RAM dirt cheapIt is more profitable to artificially create scarcity and sell less products for more money.
>>109526511ram was on the way to becoming dirt cheap with the 3 companies just releasing their high density 4GB ddr5 chips (64GB udimm sticks) until sam altman bought up 40% of the total supply and caused everyone else to panic buy to hedge against the shortage
>>109526467your post reeks of dark skin pigment
>>109527413Then tell me. Is it latency? Is it throughput? Is it random access?
>>109526467Have you tried not being brown?
>>109527499L3 cache = ball goes fastHdd = ball goes slow
>>109526408there's this cool thing people came up with where they call different things by different names. you know, because they're... different. as opposed to "the same". crazy concept, huh?

>>109526408The best SSDs have large DRAM caches and multi core controller chips. They would themselves be considered a powerful PC back in about 2001.
>>109526441What do those timings meanWhat takes 52s to get done with RAM?
>>109526888Jews are evil, what else is new
>>109528572Probably saving/reading some amount of data. Eg 100 GB or something.
>>109526441I hate speed comparisons so much but only because I want to love them. The worst is comparing programming languages.
>>109526408There's MRAM. non-volatile, fast, basically a single fancy transistor (i.e. dense).But it's expensive and hasn't be shrunk to modern nodes. So it's only used in niche applications like satellites and the write buffer of RAID controllers.

>>109529675Exactly.
>>109529584>time to read 1tb of dataFrom what? Through what? Is it just theoretical speeds or was it tested somehow?A flat contiguous file is the best case for SSDs and HDDs, but doesn't matter for L3 cache and RAM.It really is just a pointless animation.
>>109531093>From what?From the kind of memory given on the left.>Through what?Through it's interface>Is it just theoretical speeds or was it tested somehow?You can find typical speeds for each of then rather easily.Why are you so dense? This isn't anything difficult to understand.
>>109526408
>>109531673So not tested, just hopes and dreams.Not all L3 cache has the same bandwidth. RAM has an even wider range of bandwidth.But perhaps worst of all for this topic, an SSD approaching RAM speed in pure throughput still couldn't be used as RAM without serious performance loss. NAND has a lot more overhead involved in reading to and writing from it.
>>109526686this! but it'll be ignored because you're trying to discuss reality with cartoon-watching pedophile whites and kikes
>>109526408Try AXFS
