Toshiba 032G34 is a 32GB eMMC (embedded MultiMediaCard) storage module used as internal storage in various electronic devices, such as laptops, tablets, and development boards like the Jetson TX2. Unlike standard plug-and-play external drives, this component is typically soldered onto a motherboard or integrated into a system-on-chip (SoC) environment. Key Technical Specifications
The "032G34" designation serves as a vendor ID often seen in system logs or diagnostic tools for the THGBMHG8C4LBAIL eMMC Version : 5.1, which is a high-speed standard for embedded storage.
: 19nm MLC (Multi-Level Cell), balancing performance and longevity.
: JEDEC/MMCA Version 5.1 supporting 1-I/O, 4-I/O, and 8-I/O modes for data transfer.
: 153-ball BGA (Ball Grid Array) measuring approximately 11.5mm x 13mm. Common Use Cases & Identification You will most likely encounter this specific ID when: Running Diagnostics : System information tools (like toshiba 032g34
or disk utilities in Linux) will identify the internal card reader or storage as "Toshiba 032G34". System Recovery : If you are flashing a device like a Jetson TX2
or a Chromebook, this module is the target for the operating system installation. Hardware Maintenance
: Identifying the health of this module is critical for devices that fail to boot, as eMMC modules have a finite number of write cycles. Performance vs. Modern Standards
While the eMMC 5.1 interface is reliable for basic tasks, it is significantly slower than modern NVMe SSDs. Read/Write Speeds Toshiba 032G34 is a 32GB eMMC (embedded MultiMediaCard)
: Typically ranges from 100MB/s to 250MB/s depending on the specific implementation, which is suitable for web browsing and light office work but can feel sluggish for heavy multitasking. Reliability
: Includes features like health reporting and erase support to help manage the life of the NAND flash. recover data from a device using it? Some problem about tc358748 on jetson-tx2 15 Jan 2018 —
Here’s a deep-dive report on the Toshiba 032G34 – a component that, at first glance, looks like an obscure alphanumeric code, but upon investigation, reveals a fascinating intersection of consumer electronics, vintage computing, and industrial memory technology.
Here is where many people get tripped up. Sometimes, a device containing two 032G34 chips (one on top, one stacked) will be labeled as 8GB on the product sticker. If you desolder them, you might mistakenly think each chip holds 8GB—but they don’t. In a 2-chip configuration, the controller interleaves them for higher speed and capacity. The "8GB Mystery" – Why You Might Be
Quick test:
A. MLC (Multi-Level Cell) Technology Unlike modern budget drives that use TLC (Triple-Level Cell) or QLC (Quad-Level Cell), this drive uses MLC technology. This means it stores 2 bits per cell.
B. The "34nm" Node The 34nm lithography is a mature technology. While slower than modern sub-20nm nodes, it offers excellent stability and lower error rates, making these drives popular in legacy system refurbishment.
C. Industrial & Embedded Reliability Toshiba marketed these drives (often under the "SG" or "SN" series) for embedded applications. They feature:
If the PCB is physically intact but the controller is fried, you can attempt to find an identical "donor" USB drive (same make, model, firmware version) and swap the Toshiba 032G34 chip over. This is high-risk; if the controller requires a "handshake" with the NAND's unique ID, it will fail.
