- hypertele-Xii 5y agoSeems suspect. What hard drive has had RAM-like read speed for over 20 years?
- mhio 5y agoI'm guessing the page cache for hot data?
- hypertele-Xii 5y agoIs that non-volatile? (retains its memory without power)
- SavantIdiot 5y agoLet's go back to 2002, toshiba announces 1GB compact flash memory card with a read speed of 6.5MB/second (maximum). Compare that to 2002 Hynix Net DDR II with a read speed of about 100MB/s and clearly you can see how wrong I am. My bad, I was confusing Flash that had a DRAM-like interface, and Flash that could read as fast as DRAM. But I cannot edit my response now.
- Maursault 5y agoWhat is "RAM-like speed?" It certainly was a different value 20 years ago than it is today. I'm restoring a machine from 1989 that on a good day can push 15MB/s through RAM, while I think contemporary RAM will do more than 12GB/s. GP's statement is ambiguous. RAM has always been perceived as fast, but storage was always perceived as slow, for decades, and didn't begin to get fast until 20 years ago. I think if there were 15MB/s HDDs matching RAM bandwidth in 1989 it would seem a lot more impressive than a really really fast, near-RAM bandwidth-fast SSD today, even though 12GB/s is so crazy fast it is beyond comprehension.
