Industrial-grade PATA DOM for embedded systems

This BIWIN internal SSD uses a 40PIN standard IED interface and SLC flash to deliver 8GB of storage in a 54.50mm × 25.60mm × 6.20mm form factor. It is built for industrial appliances and legacy platforms that require a direct-mount PATA module rather than a cabled drive. The operating temperature spans -40°C to +85°C with storage tolerance down to -55°C and up to +95°C.

Practical limits of the 40PIN IED interface

The host transfer rate ceiling is 133MB/s, yet the drive itself tops out at 43MB/s sequential read and 21MB/s sequential write under ATTO measurement. These figures reflect the throughput ceiling of the PATA DOM design rather than the interface maximum. Buyers should match workloads to this sustained bandwidth rather than the bus specification.

SLC endurance and data retention

The SLC memory provides unlimited read endurance and a 10-year data retention rating, backed by a 2,000,000-hour MTBF and global wear-leveling. An enhanced configurable BCH ECC engine protects data integrity across the temperature range. This combination decides whether the module suits long-life embedded deployments where write cycles and thermal stress are constant.

Questions about this item

Should I pick this 8 GB SLC DOM or a larger MLC model for my legacy 40-pin IDE system?

The 8 GB SLC version gives you 43 MB/s read, 21 MB/s write, unlimited read endurance and a 10-year data retention rating, so it suits write-light industrial or embedded workloads on a 40-pin IDE bus.

What do the 43 MB/s read and 21 MB/s write figures actually deliver inside my machine?

Those ATTO numbers are the sustained sequential speeds you will see on the 40-pin IDE interface; real-world small-file performance will be lower, but the drive saturates the bus for large transfers.

The spec lists a 133 MB/s host transfer rate — what does that cap in practice?

The 133 MB/s is the Ultra DMA mode 6 ceiling of the 40-pin IDE interface; the DOM itself tops out at 43 MB/s read and 21 MB/s write, so the drive, not the bus, is the bottleneck.
