Transcend CompactFlash 1000 128 GB (TS128GCF1000)
A model-specific record of the card itself, not a reader or drive. This is a CompactFlash Type I flash card; the listed maximum transfer figures are manufacturer ratings, not a promise of camera throughput.
MEDIA ONLY: Transcend CompactFlash 1000 128 GB (TS128GCF1000). Capacity, speed series, and compatibility refer to this manufacturer's named SKU; no reader is included.
Capacity, interface and compatibility
| Manufacturer / exact SKU | Transcend TS128GCF1000 |
|---|---|
| Nominal capacity | 128 GB (decimal card label; formatted free space is lower). |
| Card / interface | CompactFlash Type I; CF parallel ATA/True IDE family interface. Type I dimensions fit a Type I or Type II CF slot; CF Type II slots are physically deeper. |
| Transfer family / UDMA | CompactFlash 1000x series; UDMA UDMA 7 capability. Exact negotiated mode depends on the host controller and firmware. |
| Rated performance / class | up to 160 MB/s read and 120 MB/s write; VPG-65 maximum series ratings. VPG-65 guarantees a 65 MB/s minimum sustained write rate under the VPG test conditions. |
| Camera and host compatibility | For a digital camera or reader with a CompactFlash slot that supports Type I CF media, UDMA UDMA 7 where applicable, and at least 128 GB capacity. Canon EOS 7D Mark II documentation identifies a CF slot with UDMA support; it is an example host, not a claim that Canon tested this exact card. Check the exact host manual's supported capacity, card types, formatting, and firmware before use. A CFexpress-only reader is not compatible. |
| Compatibility limit | Backward negotiation, maximum usable capacity, filesystem, and in-camera formatting vary by host. A faster UDMA card will run at the host's supported rate; verify exact card label and model before purchase or recovery. |
Handling and preservation
Keep the card clean and dry, avoid touching its connector, and do not remove it during access. Format it in the intended host only after backing up any data. For preservation, retain checksummed copies on separate storage and periodically verify readability; flash-card wear, aging, and controller failure are not predicted by the speed rating.
