SSD Controller Technical Reference
Maxio MAP1602 Controller Reference
The Maxio MAP1602 is a DRAM-less Gen4 NVMe controller frequently paired with YMTC 232-layer TLC at 2400 MT/s. When the FTL corrupts, the drive drops its consumer branding and presents its raw silicon identifier MAP1602 in the BIOS. The controller operates near its thermal throttling limit (86-93°C), frequently resulting in physical controller IC burnout requiring board-level microsoldering. ACELab's PC-3000 SSD supported-controller list does not currently cover this controller. For context on the SSDs we do recover, see our SSD data recovery page.
We do not currently recover Maxio MAP1602 drives
The Maxio MAP1602 controller is absent from ACELab's PC-3000 SSD supported-controller list (PC-3000 SSD / PC-3000 SSD Extended 3.8.10). No firmware utility we operate covers this controller, and chip-off does not bypass the controller-bound AES-256 encryption. Rossmann does not currently offer in-lab recovery for drives using this controller. The rest of this page is technical reference material, not a service description.

Maxio MAP1602 Specifications
| Manufacturer | Maxio |
| Interface | NVMe Gen4 |
| NAND Types | 3D TLC |
| DRAM Cache | No (DRAM-less) |
| Channels | 4 |
| PC-3000 Support | Limited / Generic NVMe |
| Chip-Off Viability | Not viable (AES-256 hardware encryption) |
Not on the ACELab PC-3000 SSD supported-controller list (v3.8.10). AES-256 hardware encryption is bound to controller silicon, so chip-off returns ciphertext. Rossmann does not currently offer in-lab recovery for this controller.
Affected SSD Models
The Maxio MAP1602 is deployed in the following consumer drives. A failure in this controller impacts access to the NAND flash on these specific models.
| # | Drive Model | Interface |
|---|---|---|
| 1 | Fanxiang S880 | NVMe Gen4 |
| 2 | Acer Predator GM7 | NVMe Gen4 |
| 3 | Netac NV7000-T | NVMe Gen4 |
| 4 | Numerous budget Gen4 SSDs | NVMe Gen4 |
Common Failure Modes and Symptoms
Each failure mode below describes a specific way the Maxio MAP1602 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.
- Firmware corruption / BSY state
When the FTL corrupts, the drive drops its consumer branding and presents its raw silicon identifier MAP1602 in the BIOS, reporting 1GB, 2MB, or 0 bytes capacity. The MAP1602 is absent from the ACELab PC-3000 SSD supported-controller list, so no firmware-utility recovery path is available in our lab for this failure mode.
- NVMe SSD not detected
- Drive shows as MAP1602 in BIOS instead of brand name
- Drive stuck in BSY state
- Capacity shows 1GB, 2MB, or 0 bytes
- Controller thermal burnout
The MAP1602 operates without DRAM and pushes Gen4 speeds, generating immense heat. The controller runs near 86-93°C under load with dense YMTC 232-layer TLC at 2400 MT/s. This frequently results in physical controller IC burnout requiring board-level microsoldering to replace surrounding components.
- Drive completely dead with no response
- Controller IC measurably shorted
- Drive failed during sustained high-speed transfer
- Visible heat discoloration on controller area
- HMB allocation failure from system crash
The DRAM-less MAP1602 stores its entire translation table in host system RAM. Any system crash, hard reboot, or sudden power loss instantly deallocates this RAM before the controller can write its mapping state to NAND, virtually guaranteeing severe FTL corruption. System stuttering and Windows event log flooding often precede total failure.
- Drive dead after system crash or hard reboot
- Windows event log showed storage errors before failure
- System stuttering preceded drive failure
- Drive not detected after unexpected power loss
How Is Data Recovered from a Failed Maxio MAP1602 SSD?
Data is recovered from a failed controller SSD by keeping the original board alive, reading controller state with PC-3000 SSD, and rebuilding the Flash Translation Layer from surviving NAND metadata. If firmware access requires Safe Mode or a volatile loader, that work happens before imaging. When the controller also handles decryption, chip-off returns unreadable data.
At our Austin, TX lab, the goal is to keep the original controller stable long enough to expose ROM state, firmware behavior, and NAND metadata without letting the drive keep writing to itself. Our SSD data recovery overview covers lab intake and triage, why SSDs report 0 bytes explains capacity failures, and how SSD controller encryption works explains why the original silicon matters.
- Maxio MAP1602 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 NVMe SSD not detected, Drive shows as MAP1602 in BIOS instead of brand name, Drive stuck in BSY state are useful to recognize, but on this controller they do not unlock a tooling path we can offer in-lab.
- Maxio MAP1602 is not on ACELab's PC-3000 SSD supported-controller list (PC-3000 SSD / PC-3000 SSD Extended 3.8.10). Without firmware utility coverage, the controller's mapping tables, internal loader, and any factory diagnostic mode are inaccessible to us, which means no firmware-level recovery is on the table.
- Maxio MAP1602 fuses AES-256 keys to the controller silicon, so desoldering the NAND chips returns ciphertext that cannot be decrypted without reviving the original controller through tooling we do not currently have for this controller.
