“I consulted Rossmann Repair Group for data recovery services. A new IT client was recently referred to me, because his main computer crashed and his business database went offline as a result. It turned out that the computer crashed because its main storage, a 500 GB Solid State Hybrid Drive, failed. That part was easy - replace it with a new 1 TB SSD and reinstall Windows along with the software he uses. However, the data on the SSHD was critical and would have meant serious problems for his business if he didn't get that back. That's where Rossmann Repair Group came in.”
Kioxia SSD Data Recovery
Kioxia (formerly Toshiba Memory) is the world's third-largest NAND flash manufacturer. Their consumer Exceria lineup uses Phison controllers paired with Kioxia's own BiCS FLASH 3D TLC NAND. The Exceria and Exceria Plus use a rebranded Phison E12C. The Exceria Pro uses the Phison E18. Each controller requires a different PC-3000 module and recovery workflow. We recover all Kioxia consumer and legacy Toshiba-branded SSDs.

How Kioxia SSD Recovery Works
Kioxia consumer SSDs use Phison controllers paired with Kioxia's own BiCS FLASH 3D TLC NAND. The Exceria and Exceria Plus use the TC58NC1202GST, a rebranded Phison PS5012-E12C. The Exceria Pro uses the Phison PS5018-E18. Recovery requires identifying the controller, loading the correct PC-3000 SSD Phison module, and rebuilding the corrupted flash translation layer. We evaluate your drive for free, provide a firm quote, and charge nothing if we cannot recover your data.
Exceria and Exceria Plus: Phison E12C Firmware Failures
The Kioxia Exceria and Exceria Plus are Gen3 NVMe SSDs built around the TC58NC1202GST controller. Despite the Kioxia part number, this is a rebranded Phison PS5012-E12C: a 4-channel controller with onboard DRAM and AES-256 hardware encryption. The Exceria pairs this controller with Kioxia BiCS FLASH 3D TLC NAND in M.2 2280 form factor.
The most common failure is FTL corruption after power loss. The flash translation layer maps logical addresses to physical NAND locations. When an unexpected shutdown interrupts an FTL write, the mapping tables become inconsistent. The controller detects the corruption at next boot and enters a firmware diagnostic mode. The drive enumerates with a vendor-specific device string and reports 0MB capacity. SMART data becomes inaccessible.
PC-3000 SSD's Phison NVMe module handles the E12C family. The recovery workflow involves accessing the controller diagnostic interface, reading the NAND contents directly, and rebuilding the corrupted FTL tables. The Toshiba RC500 (the predecessor model sold under the old Toshiba branding) uses the same controller and the same recovery procedure.
Exceria Pro: Phison E18 Gen4 Recovery
The Kioxia Exceria Pro is the brand's flagship consumer SSD. It uses the Phison PS5018-E18 controller: triple ARM Cortex-R5 cores, 8-channel Gen4 NVMe, onboard DRAM, and AES-256 + TCG Opal 2.0 hardware encryption. Kioxia pairs this with their BiCS FLASH 3D TLC NAND for sequential reads up to 7,300 MB/s.
Sustained heavy writes push the E18 controller into thermal throttling. Under prolonged thermal stress, the PMIC (power management IC) on the M.2 PCB can degrade. A failed PMIC prevents the drive from powering on entirely. The drive appears completely dead to the host system: no enumeration, no BIOS detection, no activity LED.
AES-256 hardware encryption on the E18 makes chip-off unviable. The encryption key lives on the controller die. Board-level repair (replacing the failed PMIC or voltage regulators) is the recovery path because it preserves the original controller and its encryption key. PC-3000 SSD supports the E18 through its Phison NVMe module once the controller is operational again.

Hardware Repair vs. Software Locks
Our "no data, no fee" policy applies to hardware recovery. We do not bill for unsuccessful physical repairs. If we replace a hard drive read/write head assembly or repair a liquid-damaged logic board to a bootable state, the hardware repair is complete and standard rates apply. If data remains inaccessible due to user-configured software locks, a forgotten passcode, or a remote wipe command, the physical repair is still billable. We cannot bypass user encryption or activation locks.
All tiers: Free evaluation and firm quote before any paid work. No data, no fee on all tiers (advanced board rebuild requires a 50% deposit because donor parts are consumed in the attempt).
Target drive: The destination drive we copy recovered data onto. You can supply your own or we provide one at cost. All prices are plus applicable tax.
What Customers Say About Our SSD Recovery
“Went in to ask if they could retrieve my SSD from my Surface Pro 4 for me and they gave me a good rate, but was still a bit too expensive for me. So, they let me use their equipment for about an hour until I was able to fish it out myself and recover my data.”
“Sent in a SSD for data recovery for a client of mine. Data was recovered! What else can I say. Thank you.”
“Amazing place! Super friendly and knowledgeable people! I have a LaCie Rugged Pro SSD that stopped mounting. It turns out the enclosure was the problem, not the SSD itself. They helped diagnose the issue and offered solutions—all free of charge. Great experience, and I highly recommend them! 😊”
BiCS FLASH NAND and Recovery Implications
Kioxia (jointly with Western Digital/SanDisk) manufactures BiCS FLASH 3D TLC NAND at their Yokkaichi and Kitakami fabrication plants in Japan. BiCS FLASH uses charge-trap flash (CTF) architecture, the same fundamental cell type as Samsung V-NAND. The implementation details differ (vertical channel structure, word-line geometry, oxide layer composition), but both are charge-trap designs. Current consumer drives ship with 112-layer or 162-layer BiCS FLASH.
Charge-trap cell behavior affects read retry parameters during recovery. When NAND cells degrade past their programmed threshold voltages, PC-3000's read retry mechanism shifts voltage references to find the correct charge level. BiCS FLASH and Samsung V-NAND both use charge-trap cells, but their oxide stack compositions and manufacturing processes differ. This means the optimal read retry parameters differ between Kioxia and Samsung NAND even when the host controller is identical (e.g., both using a Phison E18).
Temperature affects NAND readability. Degraded BiCS FLASH cells may read correctly at elevated temperatures (40-50C) because thermal energy shifts the electron distribution in the charge-trap layer. PC-3000's thermal stabilization feature combined with controlled heating of the drive during imaging can improve sector read rates on drives with marginal NAND health.
Kioxia SSD Controllers and Recovery Methods
TC58NC1202GST (Exceria / Exceria Plus)
Rebranded Phison PS5012-E12C. 4-channel NVMe Gen3, onboard DRAM, AES-256 encryption. BiCS FLASH 3D TLC. The E12C stores FTL metadata in NAND with DRAM caching. Power loss during FTL flush corrupts the mapping tables, triggering firmware diagnostic mode (0MB capacity). PC-3000 SSD's Phison NVMe module accesses the controller diagnostic interface, reads NAND contents with proper descrambling, and rebuilds the flash translation layer. Shares the same firmware family and recovery workflow as the Toshiba RC500.
TC58NC1202GST recovery detailsPhison PS5018-E18 (Exceria Pro)
Triple ARM Cortex-R5 cores, 12nm process, 8-channel NVMe Gen4 with onboard DRAM. AES-256 + TCG Opal 2.0 hardware encryption makes chip-off not viable. Thermal stress from sustained writes can damage the PMIC, causing complete non-detection. Board-level repair (PMIC or voltage regulator replacement) preserves the encryption key. Once the controller is operational, PC-3000 SSD's Phison NVMe module handles firmware repair and data extraction.
Phison E18 recovery detailsPhison E21T (Exceria Plus G3)
DRAMless Gen4 NVMe controller using Host Memory Buffer (HMB) for FTL metadata. The Exceria Plus G3 is Kioxia's budget Gen4 option. DRAMless design makes FTL corruption from power loss more likely because the mapping data resides in NAND rather than dedicated DRAM. The E21T does not have PC-3000 support yet (under development). Recovery options for E21T-based drives are more restricted than for the E12C or E18. Contact us for an honest assessment.
Custom Kioxia Controller (CM6 / CD8 / PM7)
Kioxia enterprise SSDs use in-house controllers (not Phison). The CM6 series ships in U.2 and E3.S form factors for data center NVMe deployments. The PM7 is a SAS-4 dual-port drive. Enterprise Kioxia controllers include hardware power loss protection (tantalum capacitors on the PCB), multi-namespace support, and enterprise-grade encryption. PC-3000 coverage for Kioxia's in-house controllers is limited to older Toshiba enterprise families. We evaluate each enterprise drive individually.
Legacy Toshiba SSDs (XG5, XG6, RC500)
The Toshiba RC500 is the direct predecessor to the Kioxia Exceria, using the same TC58NC1202GST (Phison E12C) controller. The XG5 and XG6 were OEM NVMe drives shipped in Lenovo, Dell, and HP laptops; they use Toshiba's in-house controller with BiCS FLASH NAND. Toshiba also acquired OCZ Technology in 2014. OCZ drives (RD400, VX500, Trion series) used a mix of Toshiba and Indilinx controllers. Recovery approach varies by the specific controller inside.
Toshiba drive recoveryKioxia BiCS FLASH in Other Brands
Kioxia supplies BiCS FLASH NAND to other SSD manufacturers. Western Digital and SanDisk SSDs use Kioxia/WD jointly-produced BiCS FLASH. Some Kingston, PNY, and Corsair drives also use Kioxia NAND sourced from the Yokkaichi fab. The NAND manufacturer affects read retry parameters during recovery, but the host controller determines the primary recovery workflow. A Kingston KC3000 with Kioxia NAND still uses the Phison E18 recovery module, not a Kioxia-specific tool.
DRAMless Kioxia SSDs and Power Loss Vulnerability
The Kioxia Exceria Plus G3 uses the Phison E21T, a DRAMless Gen4 controller that relies on Host Memory Buffer (HMB) for FTL metadata caching. In normal operation, the host system's RAM stores frequently accessed FTL entries, reducing latency. When the system loses power, HMB contents vanish. The controller must reconstruct FTL state from NAND on next boot.
This reconstruction fails when a write was in progress during the power loss. The FTL data stored in NAND becomes inconsistent because the write to update the mapping was interrupted mid-operation. DRAM-equipped drives (Exceria, Exceria Plus Gen3, Exceria Pro) also suffer from power loss corruption, but the failure rate is lower because the DRAM cache provides a more controlled flush sequence.
For environments with unreliable power (desktops without UPS, external enclosures disconnected without safe eject), the DRAM-equipped Exceria or Exceria Pro is a more resilient choice. If your Kioxia SSD failed after a power loss event, note the circumstances when you contact us; it helps us determine the expected FTL damage scope.
Chip-Off Recovery and Kioxia Encryption
All current Kioxia consumer NVMe SSDs use controllers with AES-256 hardware encryption. The Exceria's TC58NC1202GST (Phison E12C), the Exceria Pro's PS5018-E18, and the Exceria Plus G3's E21T all generate unique encryption keys during manufacturing. These keys are bound to the controller silicon and never exposed to the host system.
Desoldering BiCS FLASH NAND packages from a dead Kioxia SSD yields only AES-256 ciphertext. Without the original controller's decryption key, the raw NAND data is mathematically unrecoverable. This is why board-level repair (not chip-off) is the primary recovery path for Kioxia NVMe drives.
Board-level repair replaces failed passive components (PMICs, voltage regulators, capacitors) on the original M.2 PCB while preserving the controller die and its encryption key. Our microsoldering workstations handle BGA rework on M.2 2280 form factors. Once the controller powers on and initializes, PC-3000 SSD accesses the firmware layer for data extraction.
