  Felt like making this topic since we've been seeing it a lot lately in the recent footage. Yeah we have much improved graphics, new innovative controller, new OS features, etc but the most impressive thing to me is the loading times! Some games they are non-existant. Others only a few seconds. Ever since the switch to optical media we've endured loading times and some have been pretty bad but we are now closer to cartridge games than ever! Observe....
  
  
  Spider-Man Miles Morales. Spider-Man on PS4 took over 20 seconds to load the city of New York when starting and close to that during fast-travel. The sequel on PS5 loads from the menu at nearly instant speeds!

  Next comparison is Devil May Cry 5 Special Edition. On PS5 it takes only 4 seconds to load. PC is 11 seconds with SSD. Xbox is 19 and PS4 is 22.

  I'd be very curious to know what PS5 is doing to beat out PC loading times, especially because I'd assume the main reason why Xbox Series X / PS5 have better loading times is that they finally started using SSDs. It's possible PS5 may be doing some specialized caching operations.
  
  However, I'd need to know more details about the exact hardware in both the PS5 and the PC in question being tested, because there are different kinds of SSDs. There are more traditional, older style SATA SSDs that while still significantly faster than HDDs are limited by the reliance on older connection technologies. Newer types of SSDs, such as NVMe SSDs are significantly faster. By way of comparison, SATA III protocol SSDs will typically max out around 530/500 MB/s read/write speed, which is about 5 times faster than an average 7200 RPM SATA III HDD that maxes out at around 100/100 MB/s. However, out of a userbenchmark data set I observed average data speeds for an example NVMe SSD (specifically the Samsung 970 Evo NVMe PCIe M.2 500GB) hits average sequentlal speeds as high as 2,315/2,080 MB/s (2.315/2.08 GB/s).

  A lot of that is detailed in Mark Cerny's technical overview of the system hardware. The I/O throughput of the PS5 in itself is able to do 5.5gb/s raw data but with use of compression it is closer to 10gb/s and with new Kraken Oodle Textures a theoretical top speed at 22gb/s. That's a new compression technology that is able to highly compress textures with very little data loss.
  
  It has custom hardware specifically designed to remove or reduce bottlenecks in data transfer from SSD to CPU/GPU such as cache scrubbers.
  
  
  If you want to learn more it's all detailed in a very lengthy technical breakdown video.
