SSD Controller Technical Reference
Maxio MAP1602A Controller Reference
The Maxio MAP1602A is a minor silicon revision of the MAP1602 with improved power management but the same DRAM-less, 4-channel architecture. The HMB-dependent design remains equally vulnerable to power-loss FTL corruption. Extreme I/O speeds (up to 7400 MB/s) stress the ECC engine, accelerating read-disturb anomalies. AES-256 hardware encryption is fused to the controller silicon, so the NAND alone is not addressable. 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 MAP1602A drives
The Maxio MAP1602A 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 MAP1602A Specifications
| Manufacturer | Maxio |
| Interface | NVMe Gen4 |
| NAND Types | 3D TLC, 3D QLC |
| 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). The Maxio MAP1602 family is absent from every controller block on the ACELab page. 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 MAP1602A 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 | Acer FA200 | NVMe Gen4 |
| 2 | Addlink S93 | NVMe Gen4 |
| 3 | Klevv CRAS C925G | NVMe Gen4 |
| 4 | Netac NV7000-T | NVMe Gen4 |
Common Failure Modes and Symptoms
Each failure mode below describes a specific way the Maxio MAP1602A 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.
- FTL corruption from aggressive garbage collection
The controller runs garbage collection more aggressively than competitors to compensate for its lack of onboard DRAM. Power loss during an active GC cycle corrupts the flash translation layer. The drive reports wrong capacity or 0MB after the event.
- Drive shows wrong capacity or 0MB
- Not detected in BIOS after power loss
- Drive fails to initialize after outage
- NAND channel failure
One of the 4 NAND channels fails, causing the controller to report reduced capacity or hang during reads that access the failed channel's LBA range. The drive may show 1/4 or 1/2 of its expected capacity.
- Drive detected but shows 1/4 or 1/2 of expected capacity
- Read errors on specific LBA ranges
- Partial data accessible, rest returns I/O errors
- ROM mode / MAP1602A identification
When the controller panics, it drops its OEM branding and displays MAP1602 or MAP1602A in the BIOS alongside a nominal diagnostic capacity of 0MB or 2MB. The failure signature is identical to the base MAP1602.
- Drive shows as MAP1602A or MAP1602 in BIOS
- Capacity dropped to 0MB or 2MB
- Drive lost brand name after power event
- Drive completely inaccessible to operating system
How Is Data Recovered from a Failed Maxio MAP1602A 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 MAP1602A 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 Drive shows wrong capacity or 0MB, Not detected in BIOS after power loss, Drive fails to initialize after outage are useful to recognize, but on this controller they do not unlock a tooling path we can offer in-lab.
- Maxio MAP1602A 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 MAP1602A 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.

Have a Maxio MAP1602A drive?
We do not currently offer in-lab recovery for Maxio MAP1602A SSDs because the controller is not on ACELab's PC-3000 SSD supported-controller list. Contact us before shipping anything; we will confirm in writing what we can and cannot do for your specific drive.
