SLC Caching

  1. 8TB Sabrent Rocket Q (SB-RKTQ-8TB) with QLC flash
  2. 4TB Sabrent Rocket (SB-ROCKET-4TB) with TLC flash


Assuming I load up both SSDs to near-max with games, which one will bottle-neck my game loading times because of SLC-caching shenanigans? Both? Am I misunderstanding SLC Caching?

 

eg. if I load up the Rocket Q with 6TB worth of games (leaving 800GB free space left), will all my games now load at 100-200MBs speed (HDD) levels?

The Rocket has a minuscule cache compared to the Q, however it's almost 4x faster under sustained load.

I don't think that'd really affect game load times much though.

You will not see significant difference in load times when using different SSDs. Even SATA vs NVME SSDs have minimal difference in load time.

Yes, but then the question becomes: Does SLC Caching affect game loading times? In the case of the Rocket Q, it has a "dynamic cache" which uses 2TB of free space in order to reach advertised speeds.

 

Once formatted, the 8TB becomes 6.8TB, so does that mean I can only load up the Rocket Q to 4.8TB (leaving 2TB free space), after which the SSD will operate at HDD speeds???

SLC caching is used for writes predominatly, not reads (which is what loading games does). Besides even a SATA SSD is just as good for loading up games, even with NVMe they do not use much transfer speed. it's only inferior when you've got ridiculous internet speed and SATA SSDs limit install speed.

 

This is of course, unless you play simulators with humongous save files.
