M2 MacBook Pro’s 256GB SSD is only about half as fast as the M1 version’s
- watersb 4y agoApparently, the new baseline Mac is built with a NAND flash chip that's twice as dense as the previous model. The M1 256GB SSD has both channels populated, each with a 128GB NAND stack. The new M2 has only a single channel populated. Speculation is that supply-chain issues forced Apple to go with this slower design at the 256GB configuration.
- jadedbuthappy 4y agoI have always felt Mac disk IO operations to be incredibly slow. I think the problem has gotten worse since Mac started to "phone home" every time you run a new executable, etc. When running something there is a noticable delay. On Linux it's instant. This can be felt with the terminal especially.
- sdflhasjd 4y agoMacs always get good benchmarks when it comes to disk speed, and I think the software then lets it down. APFS was disappointing (although maybe thats changed now), Finder could take as long to list a large folder as Explorer on a grotty spinning rust PC would. Even on my swanky new M1 mac, browsing through the disk has a noticeable lag when compared with Windows or Linux. Builtin Archive utility is noticeably slower than alternatives too, which makes things like XCode updates particularly slow even after you've finished downloading.
