What actually matters for a fast OS and boot drive

For an OS and boot drive, real-world feel is set less by sequential peaks and more by random I/O and a DRAM cache that keeps the mapping tables off the NAND. PCIe Gen4 is the value sweet spot — Gen5 drives carry a price and heat premium that desktop use rarely justifies. Endurance (TBW) and warranty separate otherwise-identical drives at the same price.

  • Random I/O. Boot times and app launches track random reads, not the marketing sequential number.
  • DRAM cache. DRAM-less drives are fine as game shelves, but the OS drive deserves the cache.
  • TBW & warranty. At equal speed and price, take the higher endurance and longer warranty — it's free risk reduction.
  • Gen4 sweet spot. Gen5 sequential peaks rarely change desktop feel; pay for them only with a specific workload.
