At Shree Computers Sales Pvt. Ltd., our focus is on providing up-to-date information on the newest memory storage technologies. Within the scope ofindustrial micro‑SD cards, two notable examples of industrial micro‑SD cards are SDSC3 and SDS3. Although they appear to be similar, both are used in defined product families and have varying applications and functionalities related to industrial micro‑SD cards.
What Is SDSC3?
SDSC3 pertains to the industrial-level micro‑SD cards based on the Innodisk MicroSD Card 3SE3 model. These cards are compliant with the SD 3.0 / UHS-I class 10 standards and are usually offered in 4 GB to 8 GB capacities employing SLC NAND flash memory.
For applications requiring durable storage, industrial micro‑SD cards are an excellent choice.
These modules are engineered for applications that demand high reliability and long endurance:
SLC flash’s maximum program/erase cycle count is 60,000 with support for 21 TBW.
Around 30 MB/s for reading and 23 MB/s for writing are the sequential reading and writing speeds.
Operating temperature extremes for the extended grade are -25°C to +85°C and for the industrial grade -40°C to +85°C.
Capabilities in the advanced tier include power-fail management and wear-leveling, along with ECC error correction and S.M.A.R.T. monitoring.
These cards are ideal for harsh‑environment embedded systems—think industrial automation, medical devices, transport systems, digital signage, and SBCs like Raspberry Pi in mission‑critical setups.
In the meantime, SDS3, better known in the embedded and industrial storage sectors as the Innodisk MicroSD Card 3ME3, widens the product range to greater capacities and increased throughput. As opposed to the SDSC3 (3SE3 series), the 3ME3 series supports a range from 8 GB to 64 GB with MLC flash and UHS‑I Class 10 read and write speeds of 75 MB/s and 31 MB/s, respectively.
The market for industrial micro‑SD cards continues to grow as technology advances.
Key features include:
When choosing industrial micro‑SD cards, consider your specific needs.
MLC NAND with an estimated three thousand P/E cycles and approximately 170 TBW.
Complete SD 3.0 and backward compatible with SD 2.0.
Supports BCH ECC algorithms, wear leveling, and S.M.A.R.T. technologies.
Less than half a watt of power consumption (~0.5 W).
The temperature operating ranges from –40 °C up to +85 °C.
The typical warranty period is around 2 years.
This series suits use cases focused on higher storage capacity without sacrificing industrial reliability—such as IoT gateways, embedded computing systems, video surveillance, and mobile infotainment platforms.
SDSC3 vs. SDS3: How Do They Compare?
If you’re wondering which one fits your scenario best, here’s a side‑by‑side overview in narrative form:
Flash Type & Capacity: SDSC3 (3SE3) employs SLC flash with 4–8 GB capacities. MLC flash with capacities ranging from 8 GB to 64 GB is used by SDS3 (3ME3). While MLC allows for greater storage in a more compact form, SLC provides better endurance.
Performance: SDS3 can reach up to 75 MB/s read and 31 MB/s write, while SDSC3 can only deliver about 30 MB/s read and 23 MB/s write. SDS3 provides higher throughput in settings with burst data operations.
Durability & Reliability: SDSC3’s SLC design is more robust for write-intensive industrial applications, supporting up to 60,000 P/E cycles. SDS3 is appropriate for demanding data storage workloads because it has a substantially higher TBW but fewer cycles (~3,000).
Power and Thermal Range: Although both enable wide temperature operation, SDSC3 usually uses a little bit more power. Ideal for thermally or battery-powered
Availability of industrial micro‑SD cards can influence your purchasing decisions.
Why These Series Matter for Your Business
Both series are built to handle the tough conditions found in industrial and embedded settings. ECC, S.M.A.R.T., power-fail protection, shock/vibration resistance, and a wide temperature range make sure that data is safe and reliable even in terrible conditions.
Choose SDSC3 for less storage but great write endurance, depending on how you plan to use it. SDS3 is the best choice when you need more storage and faster transfer speeds, but you still want it to be reliable.
Longevity and Maintenance: Choosing the right series can help you minimize maintenance and maximize lifespan, whether you’re using signage systems, surveillance devices, portable medical units, automation controllers, or rugged computing environments.
Embedded Data Logging: SDSC3’s SLC-based endurance makes these Industrial Micro‑SD Cards ideal for applications that constantly write small logs, such as industrial sensors or fleet tracking terminals.
Multimedia or Firmware Storage: Use SDS3 when you need medium-sized storage for firmware updates, video buffers, big files, or fast data transfer.
For devices installed outside or in transport modules (like buses and trains), both series can handle extreme temperatures, vibrations, and shocks, which keeps your data safe.
Prototyping and SBC Use: SDS3 is often used in single-board systems because it has a larger capacity and faster read speeds, which is especially useful for storing media, apps, or large datasets.
Tips When Choosing Between SDSC3 and SDS3
Assess your writing intensity: Frequent writing over time requires SDSC3 due to its greater endurance.
Assess your spatial needs: SDS3 offers a greater selection of tiers above 8 GB.
Assessing compatibility with UHS‑I Class 10: These are both compliant.
Consider operational environment: Select industrial grade if the surrounding temperatures could drop to −40 °C or fluctuate greatly.
Consider device usage: Often, devices with SLC-based SDSC3 have longer warranties and projected lifespans, thus potentially lowering device maintenance expenses.
