SSD hall of fame needs new entries

Guide Anti-Hackintosh Buyers Guide (link)

After our discovery of a severe bug in the TRIM implementation of practically all Samsung SSDs we spent time investigating which SSDs are affected by all kinds of issues, and so far came with several names worth mentioning.

Working with TRIM broken (can be used with TRIM disabled, at slower boot times, or as a data storage):

• Samsung 950 Pro
• Samsung 960 Evo/Pro
• Samsung 970 Evo/Pro

Working fine with TRIM:

• Western Digital Blue SN550
• Western Digital Black SN700
• Western Digital Black SN720
• Western Digital Black SN750 (aka SanDisk Extreme PRO)
• Western Digital Black SN850
• Intel 760p (including OEM models, e.g. SSDPEMKF512G8)
• Crucial P1 1TB NVME (SM2263EN) (need more tests)

Working fine with TRIM (SATA):

• SATA PLEXTOR M5Pro
• SATA Samsung 850 PRO (need more tests)
• SATA Samsung 870 EVO (need more tests)

Working fine with TRIM (Unbranded SSDs):

• KingDian S280
• Kingchuxing 512GB

Incompatible with IONVMeFamily (die under heavy load):

• GIGABYTE 512 GB M.2 PCIe SSD (e.g. GP-GSM2NE8512GNTD) (need more tests)
• ADATA Swordfish 2 TB M.2-2280
• SK Hynix HFS001TD9TNG-L5B0B
• SK Hynix P31
• Samsung PM981 models
• Micron 2200V MTFDHBA512TCK
• Asgard AN3+ (STAR1000P)
• Netac NVME SSD 480

There are several very good comparison charts containing various SSDs and their controllers: one, two. Since SSD compatibility usually is controller-based, picking up an SSD with a known to be compatible controller has a high compatibility chance as well.

---

In addition to that, I would like more people to run tests on their platforms to determine whether their SSD TRIM implementation is broken or not.

Preconditions:

• Tested SSD is the boot SSD (i.e. macOS is installed on it).
• Tested SSD is APFS-formatted.
• Tested SSD must be actively used with macOS installation being at least a month old.
• OpenCore 0.6.7 or newer is used.

The idea is to measure the boot time either between motherboard logo and macOS login screen or between Apple logo and macOS login screen. The former is strongly recommended due to possible GOP issues. All the measurements needs to be done with different SetApfsTrimTimeout values set in OpenCore. Each measurement must be made at least 2 or 3 three times to ensure no sporadic results. The values to test are as follows:

1. 0 (means TRIM is disabled)
2. -1 (standard timeout, equals roughly 10 seconds, means TRIM is enabled and runs up 10 seconds during boot)
3. 4294967295 (maximum timeout, TRIM is enabled and runs as long as needed)

• An SSD with a decent TRIM implementation should behave as follows. Value 1 will be negligibly the fastest. Value 2 might be slightly slower than 2 (way less than by 10 seconds, maybe 2-5). Value 3 should be equal to value 2.
• An SSD with a broken TRIM implementation, like Samsung, will have value 2 slower than value 1 by 10 seconds, and value 3 will be noticeably slower than value 2, usually by 30-60 seconds.

Please write include the following information in the report:

• SSD type (NVMe or SATA), model, and storage size
• Motherboard and CPU used
• macOS version used
• Test results grouped in 3 sections (a total of 6 or 9 values).

Note: If you use FileVault 2, you can use sudo fdesetup authrestart command to skip UEFI login. AuthRestart must of course be enabled. I would also advise to disable the OpenCore Picker (ShowPicker = NO).

@qin9125 > thank you wd sn550 works fine

Bro I'm also using SN550 but I don't know why I'm getting this and stuck in this line onlyCouldn't alloc "AppleKeyStoreTest". And for more information, how it happened? Here's the story-> My elec went out after upgrading to ventura latest version successfully and was running the latest version on the latest updated opencore version and config both. After when elec came back, I tried to open my pc and then logged in opencore boot menu then logged in again for the user access. Also last time, after updating to the latest version when I logged into my desktop. One popup showed up at the time and in that it is showing "Some updates cannot be installed". After that again elec went out and then came backs, and then again I tried to open my pc and from that time it is continuously stuck on this couldn't alloc "AppleKeyStoreTest". Please help me bro! I'm also on discord and my username - youngmoguler. Please tell yours, so that I can reach you there.

Thanks in advance.

Hi, i have used samsung 970 EVO with no issues on big sur in the last years, now i want to upgrade to a newer version of osx. Since all samsung nvme are affected by trim issues, am i forced to switch to another ssd? I already own a sandisk extreme pro, should i clone my data to this disk before upgrading?

Best thing to do is switch to WD

OK, but 1st post says:

Working fine with TRIM: Western Digital Black SN750 (aka SanDisk Extreme PRO)

and found some reviews like this "The WD Black SN750 is equipped with the same controller and NAND parts as last year's WD Black and SanDisk Extreme Pro, and the only differences in chip markings appear to be date codes or lot numbers."

So should i give it a try?

I looked at techpowerup.com and they agree on the controller and memory with sn 750/770, there is a high chance that it will work

edit: after cloning my old 970 evo to my new sandisk extreme pro everything works fine.

Hi i recently built my hackintosh i don't know how you do those test.. i checked and my APFSTrim is set to -1

ASUS TUF Z690 D5 2 Samsung NVME 990 (1 windows - 1 ventura) RTX 4070 RX 580

on my macos ventura with AmorphousDiskMark i got this result:

Except the slow boot i don't see any issue or trouble... but if you can suggest the correct test to do .. i would be happy to do...
