If you’ve been following my microSD Card Survey, you might have noticed that I publish manufacturer IDs for (almost) all of the cards that I’ve tested (save a few where they came DOA or where I tested them before I thought to dump the registers off the card).
I know that there are other resources out there that have compiled lists of SD card manufacturer IDs, but I thought I’d publish my own based on what I’ve seen during the course of my testing. So without further ado:
| Manufacturer ID | OEM ID(s) | Associated Brand Names |
|---|---|---|
00 | 0000 | Auotkn, “Lenovo” (knockoff), QEEDNS, QWQ, SanDian, “Sony” (knockoff), “Xiaomi” (knockoff) — pretty much any fake flash vendor who wants to cover their tracks. |
00 | 3000 | Auotkn |
00 | 3432 (ASCII: 42) | Somnambulist, Gigastone, “Sony” (knockoff) |
02 | 544d (ASCII: TM) | Kioxia (formerly Toshiba) |
03 | 5344 (ASCII: SD) | SanDisk, WD |
05 | 000c | “Lenovo” (knockoff) |
09 | 4150 (ASCII: AP) | ATP |
1b | 534d (ASCII: SM) | Samsung |
1d | 4144 (ASCII: AD) | ADATA |
271 | 5048 (ASCII: PH) | Delkin Devices, HP, Integral, Kingston, Lexar2, onn., PNY |
28 | 4245 (ASCII: BE) | Lexar2 |
56 | 5344 (ASCII: SD) | Auotkn, QEEDNS |
6f | 0303 | Hiksemi, Kodak, Lenovo, Microdrive, Netac, XrayDisk |
74 | 4a60 (ASCII: J`) | Gigastone, Transcend |
89 | 0303 | Netac |
9f | 5449 (ASCII: TI) | Amzwn, Kingston, Kodak, Micro Center, Silicon Power |
ad | 4c53 (ASCII: LS) | Amazon Basics, Chuxia, Lexar3, OV, Raspberry Pi4 |
df | 2306 | Lenovo |
fe | 3432 (ASCII: 42) | ALUNX, Auotkn, Bekit, Cloudisk, HP, Reletech |
1Multiple sources attribute this manufacturer ID to Phison. While I don’t disagree, I just haven’t come across any Phison-branded cards yet.
2The cards tested here dated to before Lexar’s sale to Longsys.
3The cards tested here dated to after Lexar’s sale to Longsys.
4The announcement on Raspberry Pi’s website specifically mentions that they worked with Longsys to develop these cards — so I think that pretty much confirms that this manufacturer ID belongs to Longsys.
