For people interested in a new WD SN550 1TB, it's currently available on Amazon UK for 69GBP
I think I haven't seen such low price in pounds..lol

Note that 2015 13-inch Macbook Pro came with dual core (four threads) processors. From my quick bench using fio, SN500's random 4k read is about 350k IOPS (close to WD's spec 410k). Given the machine under test is only dual core, I would think 350k is decent. The random 4k write is a miserable 50k IOPS (far below WD's spec 405k). Given the core counts, I give WD the benefit of doubt though I have expected way higher than 50k.

I hope Updating to Mojave will get me to the latest BootROM. I just tried creating a Big Sur USB installer and it failed miserably. I don't know what happened, but downloading Big Sur (and Catalina as well) from the Mac App Store does not seem to download the full installer. I was expecting a 12.6 GB app, but instead I got a 28MB app. Opening the app, it goes right to the Big Sur installer, but the Terminal command doesn't seem to recognize it as an app that can used to create a bootable drive.Seems to be fine, I would do it the same way. As for the latest Boot-ROM version number, you can check this website:
For the moment it looks that installing Mojave will give you the latest Boot-ROM for your Mac as well. Just in case.Which firmware should your Mac be using? (version 5)

How to Stop Windows From Restarting After a BSOD20H2 keeps BSOD at 93% then gets rolled back. Trying everything in the toolkit to update. Running out of options. If something works I will post an update.
this is proving to be quite challenging as the BSOD flashes up for a second and reboots. I can’t see why it failed. Anyone know where the crash logs are kept?
Once I figure out how to update Windows I will then figure out which drives to send back to Amazon.
I have on hand:
MP510
P5
8200 pro is coming today.
Samsung 970 Evo Plus (sending this back due to drawing too much power).
Not sure if this relates, but I have just compared APFS performance to HFS+ performance. If you have some space on your SSD for these tests, it is really easy to create a HFS+ partition alongside with APFS.This has been spinning in my head for a long while. Finally I solved the riddle - why random 4k write is so miserable in macOS i.e. way below what the hardware is capable of. In fact, SN550 is innocent here.
I believe the issue applies to all 3rd-party NVMe drives in macOS and the problem is two folds - the filesystem and the NVMe driver in macOS.
The 50k IOPS (~200MB/s) was run on SN550 formatted as APFS. If formatted as HPF+, the same test should achieve double speed ~100k IOPS (~400MB/s). But that's still only about a quarter of what SN550 is capable of. Here comes the suspicion in the NVMe driver. I believe Apple does (perhaps deliberately) not optimise the NVMe driver for 3rd-party m.2 drives (as Apple's SSDs don't use it). I believe for majority users of this thread, it's "non-issue" as everyday laptop workloads will hardly hit Apple's cap.
Worth pointing out forum members saw the same issue and did some digging in the following thread: https://forums.macrumors.com/threads/cmp-slow-afps-4k-write-performance.2166560/. The key message is very clear: under the same test condition (CPU, SSD, benchmark s/w), HPF+ performs better than APFS on 3rd-party NVMe SSDs.
So about SN550, one con's less.
Peace
Can anyone point me to where I can find the default values?
The results were more or less the same with either High Sierra and Mojave as boot volume.
APFS was faster here. But when I did a real-world test, measuring the speed with a huge file in Photoshop, the speed difference wasn't really noticeable.
Hmm, if I understand you correctly:I did the SN550 tests in Catalina. Recently did it in Big Sur with ADATA SX8200 Pro and same observation. Actually that was the moment I started rethinking what's going on. I believe ppl in the thread that I linked to above did it in Mojave & Catalina.
Btw, do you think your HPF+ random 4k write is exceptionally low? I couldn't find official P2 specifications on random 4K. Perhaps you need to boot into Windows To Go or Linux Live USB to estimate P2's limits on random 4k.
One thing can't emphasise once more: it's macOS that limits random 4K write performance to its fullest.
Hmm, if I understand you correctly:
You suppose that 4K write performance with NVMe drives is lower on MacOS than on Windows 10?
I think a tool to compare Windows with MacOS is needed. The only tool that I know of is AmorphousDiskmark, which aims to make the results comparable to CrystalDiskmark in Windows.
But the Crucial P2 performs better in a PC, so it will probably do so in the MacBookPro11,3 :
UserBenchmark: Crucial P2 3D NVMe PCIe M.2 2TB CT2000P2SSD8
Well, if it is legitimate to compare the numbers between AmorphousDiskMark and the Userbenchmark, I see the Crucial P2 in the MacbookPro11,3 well in the average PC Windows 10 range. Or isn't it?MacOS significantly handicaps 4k random write performance on 3rd-party m.2 NVMe drives. The problem is more serious when formatted as APFS than HPF+ (N.B. your data point is an exception to this). However, even with HPF+, 4k random write on these 3rd-party NVMe drives are less than 50% of what hardware is capable of. Also, it's unrelated to PCIe bandwidth.
Crucial doesn't publish specification on P2. As I know Linux and Windows do not have such handicaps, I was suggesting if you want to estimate your P2 random 4k specs. Run it on Windows or Linux.
The problem applies to all 3rd-party NVMe drives as I said in my previous post. Here let's use P2 for illustration again.
Didn't read test methodologies there. We could do an estimation from the above data point regarding P2's random 4k performance
Compare to your result. P2 formatted as APFS: random 4k write only about 26% of what hardware is capable of. random 4k read is about 78%.
- random 4k write: 1350MB/s or 330k IOPS
- random 4k read: 1100MB/s or 270k IOPS
What concerns you most? Speed? Price? Power consumption?what is the best SSD drive for macbook pro 2017?
low power consumption, and if it would have the same speed as the original apple ssdWhat concerns you most? Speed? Price? Power consumption?
Are you intending to use BootCamp/Windows?
Which MBP 2017? If you have a Touchbar MBP, I'm pretty sure that the SSD is not removable.
I watched a video on Youtube regarding the non-Touchbar MBP. The form factor on the SSD used is not the same as older MBP and MBA. The adapter is also different.low power consumption, and if it would have the same speed as the original apple ssd
No i'm not intending to use Bootcamp/windows, maybe only Prallax.
I have mpb a1708 128ssd.
I want to replace original SSD.
Min capacity 512Gb.
Does anyone have experience with the Kingston NV1? I had ordered one last week on sale directly from Kingston to try and got an adapter from Amazon (non-sintech). I'm now waiting for a sintech adapter to see if that is at fault, but with this adapter, the computer does not detect it at all while booted from a Mojave Installer USB Drive. The computer's BootROM is updated as I was running Big Sur previously on my Apple SSD in my Mid-2014 13" MacBook Pro.
Anyone with any advice?Hi there!
I've read the OP but I still have some questions about upgrading my macbook (pro retina 13" 2015) to a third party ssd.
- I'm running Big Sur 11.6, should I be ok with sleeping/hybernation issues?
- Is there any problem with importing a Time Machine backup after the upgrade?
- I seem to understand that NVMe drives use more battery...why that happens?
- My idea is to get a 500gb/1Tb Samsung (I had good experience with their ssd) NVMe drive, any suggestion on the model? I'm looking into the 970 Evo Plus or the 980, any major difference? Or if you do not reccomend Samsung, any suggestion in the 150€ price range?
Thank you so much for your help.
