| + | Over the years only had problem with WD SSD on 2014 MBP as far I remember. All the rest of SSDs work just great. Don't be "scared" away by notes around Sintech in SSD selection as - only Samsung/Crucial. There are other decent brands too. PCIE Gen3 is that for all - no magic 🙄🤭 |
| So ***BIG However*** beyond speed there are other tech spec which matters between GEN3 & GEN4 PCIE standards. DRAM Cache, reliability, performance etc. So picking a good GEN4 SSD for a good price tag is not "overspending". |

***Just been researching few bits and bobs.*** ***Quick conclusion: Shameless 'Copy/paste' 27" 2017 VS 2019.*** Quick comparison about 27" 2017 VS 2019 pic: [image|3459321] Credit to [link|https://everymac.com/systems/apple/imac/imac-aluminum-tapered-edge-faq/differences-between-imac-aluminum-mid-2017-early-2019-models.html|everymac.com] Everything is pretty much.. same .. surprisingly.. 😎 2 years difference? ***CPU:*** I would be highly surprised if anyone ever put GEN 9 CPU in 2017 iMac - will it work? Both on same socket. ***Sockets Supported:*** FCLGA1151 Detailed comparison from Intel: https://www.intel.com/content/www/us/en/products/compare.html?productIds=97144,134896 ***Summary (ONLY significant difference):*** 1) GEN9/GEN7 - larger cache (9MB over 6MB), 2) GEN9/GEN7 - MAX Ram support (128GB over 64GB) ***GPU:*** ***This is what I was interested personally.. If you can get your hands on 2017 with 8GB for a good bargain price - Grab it hands down honest recommendation. Explaining why below.*** Essentially the difference is "X" .. now then.. 😏🤡 Radeon Pro 580 VS Radeon RX 580X Credit to [link|https://gagadget.com/en/graphics-cards/radeon-pro-580-vs-radeon-rx-580x/|gadget.com] [image|3459323] ***Verdict and final word for those with.. Buts! Or lazy butts : ) ✌️*** Don't let yourself be a Apple's victim - chasing this "NEW" supported tech. Always balance out what matters and value for money.

Just something I thought sharing while I got hands on 2 machines 2017 & 2019 Thought that maybe at least.. 2019 would have a "better" PCIE support for SSD upgrade .. but.. no.. even that is 2017 "level".
