Not a very relevant point - the difference between 500 MB/s and 5 GB/s mass storage is rarely noticeable.

- adastra22 2y agoDepends on what you're doing. It's very noticeable for my work.
- ahartmetz 2y agoIn my case, software development with C++. It's basically small files and a lot of disk cache.
- adastra22 2y agoI’m processing 100’s of GB of information (the whole historical bitcoin blockchain). Enough to not fit in RAM, but the computation I’m running is fast enough to not be CPU bound. At home I have a desktop rig with multiple TB RAM and a fast server CPU. I would normally ssh into that to run tests with the chain mounted on a /dev/shm partition, which was a pain and only was accessible when I was at home. With my new MacBook Air, the upgraded internal drive is large enough to hold the full historical chain, and streams from disk fast enough to finish a run in comparable time. So now I’m mobile and can work from anywhere, with an entry point laptop replacing a dedicated server! That’s a big change for me. I recognize not everyone’s tasks are bottlenecks the same way though.
- jlokier 2y agoSame here, but processing the entire history of Ethereum instead.
- kccqzy 2y agoAbsolutely. That's why in newer computers with M.2 storage I'm delighted to find the existence of SATA SSD storage in M.2 form factor. Now I don't have to pay NVMe prices any more. Whereas with Apple, I believe the only choice is NVMe storage. What if I want more but slower SSD storage?
- ttkari 2y agoYou mean M.2 SATA storage is available cheaper than M.2 NVMe where you live? Over here there are very few options in M.2 SATA form factor and the prices are almost double that of M.2 NVMe, which is really not that suprising given the obviously very much higher volumes of NVMe parts.
- kccqzy 2y agoHuh I just checked prices again and you are right. I must have remembered wrong. I stand corrected.
- adastra22 2y agoI think this is backwards? NVMe should be faster than SATA. I don’t think Apple uses either though. They directly connect the CPU to storage on the SoC. Another commenter above is saying they don’t even use PCIe.
- kccqzy 2y agoNVMe is faster than SATA. But for my purposes SATA is fast enough; I just hope manufacturers would make SATA SSDs cheaper than NVMe SSDs. But alas that's not the case.
- Cumpiler69 2y ago>in newer computers with M.2 storage I'm delighted to find the existence of SATA SSD storage in M.2 form factor Now I don't have to pay NVMe prices any more. In which year do you live in? New computers haven't been shipping with M2 SATA storage since like ~2018, and SATA SSDs haven't been cheaper than NVME since at least ~2020. NVME has been cheaper than SATA for many years already.
