SSD Controller Technical Reference
Samsung MKX Controller Reference
Samsung's MKX controller powers the 870 EVO and 870 QVO. ACELab's PC-3000 SSD supported-controller list does not currently cover this controller, so we take these drives case by case rather than as a published service. For the rest of the workflow at our Austin, TX lab, see our SSD data recovery page.
We take Samsung MKX drives case by case
The Samsung MKX is not on ACELab's PC-3000 SSD supported-controller list (PC-3000 SSD / PC-3000 SSD Extended 3.9.8), so no firmware utility we operate rebuilds its translator. We still look at these drives one at a time. A drive that still enumerates often needs nothing more than a logical recovery. Contact us with the model & the symptom before you ship anything, & we will tell you in writing what we think is possible.

Affected SSD Models
Samsung's in-house controller is the part inside the following consumer drives. A failure in this controller impacts access to the NAND flash on these specific models.
| # | Drive Model | Interface |
|---|---|---|
| 1 | Samsung 870 EVO | SATA |
| 2 | Samsung 870 QVO | SATA |
Common Failure Modes and Symptoms
Each failure mode below describes a specific way the Samsung MKX fails and the symptoms you will observe. If your SSD matches any of these patterns, do not run recovery software; it cannot communicate with a dead controller. See the zero-byte SSD diagnostic reference for a deeper technical explanation of controller and FTL failures.
- Controller failure causing non-detection
If the MKX controller is dead, the drive does not register in BIOS or the OS.
- SATA SSD not detected
- Drive completely invisible to BIOS
- No response from drive
How Is Data Recovered from a Failed Samsung MKX SSD?
Controller-class recovery starts by keeping the original board alive, reading controller state, and rebuilding the Flash Translation Layer from surviving NAND metadata. No PC-3000 SSD utility rebuilds the translator on the Samsung MKX, so the firmware-level half of that workflow is closed to us. What is left is triage, logical recovery on a drive that still enumerates, and board-level repair of the original silicon.
Firmware access that needs Safe Mode or a volatile loader happens before any imaging. File-copy software never reaches this stage, since it needs a controller that already enumerates to the host. When the Samsung MKX also handles decryption, chip-off returns unreadable data, so the original silicon has to stay in the loop.
Holding a controller stable long enough to expose ROM state, firmware behavior, and NAND metadata without letting the drive write over itself is the core of controller-class recovery. Our SSD data recovery overview covers intake & triage, why SSDs report 0 bytes explains capacity failures, & how SSD controller encryption works explains why the original silicon matters.
- Samsung MKX failures usually break the Flash Translation Layer, firmware boot path, or local power rail before macOS or Windows sees a mountable volume. Symptoms such as SATA SSD not detected, Drive completely invisible to BIOS, No response from drive tell us which bench the drive belongs on.
- Samsung MKX is not on ACELab's PC-3000 SSD supported-controller list (PC-3000 SSD / PC-3000 SSD Extended 3.9.8), so no firmware utility we operate rebuilds its translator. We look at these drives one at a time instead of publishing a blanket refusal.
- If the controller is electrically dead, the work is board-level repair of the original silicon. The media key is generated on and wrapped by that controller, so a donor chip reads its NAND as ciphertext.

Have a Samsung MKX drive?
The Samsung MKX is not on ACELab's PC-3000 SSD supported-controller list, so no firmware utility we operate rebuilds its translator. We take these drives case by case anyway. Contact us before shipping anything; we will tell you in writing what we think is possible for your specific drive.
