Sounds right. Not sure what you mean be "adjustments for performance." I updated with a 1TB Hynix P31 a couple of weeks ago (see post 11,728). No firmware updates required. YMMV, depending on how long your Hynix was on the shelf and whether it's the same model. I booted from a USB drive, formatted the new SSD, and ran the installer. Very straightforward, no hitches. Hopefully that's how it'll go for you. Let us know how it turns out.
Thank you for sharing this!
sure i've already done the test (the reason i didn't go straight to the latest and greatest is because i thought it would be taxing on old model). as far as crash is concerned i'd say so far so good. i sure will come back and update this post if i encounter another crash by then i'd have probably returned the sn580 and reverted to my old trusty sn750. btw sn750, when idle, runs at 40+ celsius when room temperature is about 20 celsius and drains the battery considerably faster than the stock ssd does, that prompts me to make the transition in the first place, power efficiency and low temperature instead of data throughput rate are what i'm looking for in a ssd for laptop usage. one funny thing that i've encountered after this new installation is Preivew exited by itself when i had a PDF file open side by side with Xcode. whether by clicking the Preview app icon on the Dock nor double-clicking the pdf file i just couldn't have it running again, like always a reboot solves the problem... sometimes it did feel laggy when i scrolled quickely through a large pdf file that's like 100MB more so.
Lots of factors could be causing this, these are a few of the possibilities:
i've got two different adapters each from different manufacturers, both of them work their magic with sn750 on Ventura as well as Sonoma; none of them works well with sn580 on either OS (crashes after a couple of hours, i couldn't give you the exact steps to reproduce the crash, seems random). IMHO, it has nothing to do with physical connectivity.
yes, i've checked the drive on a Windows pc, the western digital dashboard shows the firmware is already up to date.
temps are fine ranging from 30 to 45 give or take under constant surveillance of MacFanControl
i just leave the OCLP setting as is, the option is checked by default.
The EFI payload for the final version should be loaded as part of 11.x (an install on a clean drive should be able to update the firmware if yours didn’t, it should be able to overwrite what you have)
How's Sonoma running on the 2015 MBA? I'm still on Monterey 12.7.2. I'm a bit leery of loading OCLP. This thing been running well on ADATA 2TB for 3-4 years now. If I had another drive I might try it just to see.
New UPDATE from me
OCLP’s third party PM uses the NVMEFix kext (patched Apple NVME storage driver, which is developed by the OC team to address some issues with third party hardware)

I believe the longer adapter is designed to support single sided drives, the shorter one is designed for double sided NVME drives.
I used the short Sintech adapter with the P31 in a 2013 MBA. I've had no problems. I decided against the longer version because of concerns about fit and heat, but it might be just fine.
If you have iCloud activated, your personal files will be stored there (you can double check it on iCloud.com).
Great information, thank you. I'm hoping to be able to make a bootable USB drive. I wouldn't presume there is some other way than the USB drive to just swap the hard drive and get a fresh version of the OS installed.
The easiest way is to use a USB drive.
Woohoo, the laptop stayed on long enough for me to create a bootable disk.
