The TF Purple Card T series is the speed line of our TF family: TF-32G-T, TF-64G-T, TF-128G-T and TF-256G-T. Every capacity reads at 100 MB/s; write speed scales with capacity, from 65 MB/s at 32 GB to 85 MB/s at 128 GB and 256 GB. TLC flash, the A1 application class and a 0–70 °C operating range make it the pick for big-bandwidth, high-IOPS consumer jobs — drones, game consoles, action cameras and phone storage. One honest note: for around-the-clock CCTV recording, the Red Card MT series is the right tool, not this one.

Is this the right card for you?

Plain-language guide — based only on what this product actually does.

Drones & action camsHigh-bitrate 4K clips need sustained write headroom — 85 MB/s at 128/256 GB keeps the buffer empty and the recording clean.

Game consoles & handheldsThe A1 random-performance class keeps game libraries and app data responsive — load screens, not loading waits.

Phone & tablet expansion100 MB/s reads make photo libraries and offline media feel local, not card-bound.

Not the right pick if you need…

7×24 continuous CCTV recording — that duty belongs to the Red Card MT series (3000 P/E, −25–85 °C)
Sub-zero or sun-baked outdoor sites — this series is rated 0–70 °C; the Red Card covers −25–85 °C
The lowest possible price for casual storage — that is what the T-C White series is for

Who uses it, where it goes and how to use it

Written for the Uniview TF Purple Card T series (TF-32G-T to TF-256G-T) from its own specifications: high-speed microSD, 100 MB/s read, 65–85 MB/s write, A1, TLC, 1000 P/E, 0–70 °C.

Who it is for

Drone pilots and action-cam users — High-bitrate 4K clips need write headroom; the 128 GB and 256 GB cards write at 85 MB/s, the fastest in the TF family.
Game consoles and handhelds — The A1 application class keeps game libraries and app data responsive, and 100 MB/s reads shorten load times from the card.
Phone and tablet storage — Photo libraries, offline maps and media open quickly at 100 MB/s read, on every capacity from 32 GB to 256 GB.
Not for 7×24 CCTV — With 1000 P/E and a 0–70 °C range, this series is built for speed, not round-the-clock writing in outdoor housings; for camera SD slots the page points to the Red Card MT series.

Where and how to use it

Format in the device that records — Format the card in the drone, camera or phone that will use it, not on a PC, so the device creates the folders and file system it expects. Reformat in the device after each offload instead of deleting files one by one.
Start at 128 GB for high-bitrate video — Write speed steps up with capacity: 65 MB/s at 32 GB, 70 MB/s at 64 GB, 85 MB/s at 128 GB and 256 GB. For 4K recording, choose 128 GB or 256 GB.
Check the device's card limit — Phones, drones and consoles each have a maximum microSD size. Check it before buying the TF-256G-T; older devices may not read large cards.
Keep it within 0–70 °C — Do not leave the card in a device on a car dashboard in summer sun or use it below freezing; the rated range is 0 °C to 70 °C. For hot or cold outdoor duty, the Red Card MT is rated −25 °C to 85 °C.
Use a fast card reader — To copy footage at up to 100 MB/s, use a USB 3 card reader or port; a USB 2 reader or an old laptop slot limits the transfer well below the card's speed.

Hours of video per Purple card

Every capacity reads at 100 MB/s; write speed rises from 65 to 85 MB/s with capacity. The table shows hours of continuous video at typical drone and action-cam bitrates and how long a full card takes to copy at the 100 MB/s read speed.

	Write speed	20 Mbps	60 Mbps	100 Mbps	Full copy at 100 MB/s
TF-32G-T · 32 GB	65 MB/s	3.6 h	1.2 h	0.7 h	5.3 min
TF-64G-T · 64 GB	70 MB/s	7.1 h	2.4 h	1.4 h	10.7 min
TF-128G-T · 128 GB	85 MB/s	14.2 h	4.7 h	2.8 h	21.3 min
TF-256G-T · 256 GB	85 MB/s	28.4 h	9.5 h	5.7 h	42.7 min

Pick TF-128G-T or TF-256G-T for 4K: 85 MB/s write, and about 2.8 h or 5.7 h of footage at 100 Mbps.
TF-32G-T and TF-64G-T suit phones, consoles and 1080p clips at about 20 Mbps (3.6 h and 7.1 h).
For a security camera SD slot, choose the Red Card MT series instead.

Bitrates of 20, 60 and 100 Mbps are assumed examples for 1080p and 4K recording, not page figures; check your device's own setting. Hours = capacity × 10^9 ÷ (bitrate ÷ 8) ÷ 3600, using nominal capacity; usable space after formatting is a little lower. Copy time assumes the reader sustains 100 MB/s.

High-Speed TF Card FAQ — TF Purple Card T Series

How fast is the Purple Card T series?

Sequential read is 100 MB/s on every capacity — the fastest in our TF family. Write speed scales with capacity: 65 MB/s at 32 GB, 70 MB/s at 64 GB, and 85 MB/s on the 128 GB and 256 GB cards. The A1 rating adds solid random performance for app use.

Is it suitable for 24/7 security camera recording?

It is tuned for speed rather than continuous overwrite: endurance is 1000 P/E cycles and the operating range is 0–70 °C. Use it where it excels — drones, game consoles and phone storage. For 7×24 CCTV loop recording, ask us for a high-endurance surveillance card from the same TF family instead.

What is this card best used for?

The factory positions the T series for drones, game consoles and phone storage — workloads that need fast sequential reads and quick file transfers rather than endless rewrite endurance. TLC flash, the A1 rating and 100 MB/s read make it the pick when transfer speed is the priority, in capacities from 32 to 256 GB.

What does the A1 rating mean for phone use?

A1 is the SD application-performance class: the card sustains the random read/write operations that apps generate, so it can store and run apps on a phone rather than just hold files. Combined with 100 MB/s sequential read, the 32–256 GB cards work well as phone storage expansion.

What are the endurance and temperature ratings?

Endurance is rated at 1000 P/E cycles on TLC flash, and the operating range is 0 °C to 70 °C. That covers consumer devices in normal daily conditions, but it is not the specification set for always-on surveillance inside sealed outdoor housings — pick a surveillance-grade card for that duty.

How do I avoid counterfeits when buying in bulk?

We support placing the purchase order with Uniview under your own company name, so the order is officially registered to you and the goods are traceable to the factory. Small and mid-size orders can be delivered straight to your forwarder's warehouse in China on EXW or FOB terms.

How many hours of 4K video fit on a TF-128G-T or TF-256G-T?

It depends on the bitrate your device uses. At 60 Mbps the TF-128G-T holds about 4.7 hours and the TF-256G-T about 9.5 hours; at 100 Mbps, about 2.8 and 5.7 hours. Usable space after formatting is a little lower than the nominal size, so leave some margin for a long flight or shoot.

Why don't I get 100 MB/s when copying from the Purple Card T?

100 MB/s is the card's maximum sequential read; the reader and computer must keep up. A USB 2 reader, an old built-in laptop slot or a slow destination drive will cap the speed, and thousands of small files copy slower than a few large video files. Use a USB 3 reader on a USB 3 port and copy to a fast disk; at 100 MB/s a full 128 GB card takes about 21 minutes.

Is the 32 GB Purple Card T slower, and does it matter?

Reading is the same 100 MB/s on all sizes; only writing differs: 65 MB/s at 32 GB, 70 MB/s at 64 GB and 85 MB/s at 128 GB and 256 GB. Even 65 MB/s equals about 520 Mbps, well above normal video bitrates, so the bigger difference is how long the card lasts before it is full. The page advises starting at 128 GB for high-bitrate video.

Will my phone or drone accept the TF-256G-T?

Only if the device's own specifications list microSD support up to 256 GB or more; the card cannot raise a device's limit. Most recent phones and drones list it, but older or budget models may stop at a smaller size. Check the manual or spec sheet, then format the card in the device on first use.

Can I use the Purple Card T in an indoor camera that records only on motion?

It will work, but it is not the card we recommend for that job. Even motion-only cameras write often and run for years, and this series is rated 1000 P/E and 0–70 °C, while the Red Card MT is rated 3000 P/E and −25 °C to 85 °C. For any camera, and especially outdoor ones, choose the MT series.
