Which USB drive the Model Y needs
Dashcam and Sentry Mode in the Tesla Model Y record to a USB drive, not to the car. The Model Y owner’s manual sets a short list for that drive: capacity, write speed, USB 2.0 support, and format. Most Model Y cars already have a flash drive in the glovebox port from the factory. The reason to replace it is room. The manual says the amount of footage kept before it is overwritten depends on the size of the drive, from as little as 1 hour on a small drive up to 24 hours on a drive of 1 TB or more.
These drives move up that scale. The Samsung BAR Plus 256GB (official page) is the cheap USB-A stick. The Samsung BAR Plus 512GB (official page) is the same stick with twice the room. The Samsung T7 Shield 1TB is the SSD at the size the manual ties to its longest recording window. The Samsung T7 Shield 2TB (official page) is the same SSD with more space for saved clips and Sentry events.
Which Model Y USB port to use
The port matters as much as the drive, and it depends on when the car was built.
2025 and later Model Y. The 2025+ manual lists one USB-A port inside the glovebox, equipped with a USB flash drive, and calls it the place to save Sentry Mode and Dashcam video. The other USB-C ports, in the rear compartment of the center console, below the rear vents, and in the 6-Seater under the third-row cushions, are listed for charging.
2020 to 2024 Model Y. The 2020–2024 manual says the port depends on build date, so open the glovebox and look.
- There is a USB-A port in the glovebox. Record there. Tesla recommends it for video because power consumption is minimized and the location is more secure. On some cars built after about November 1, 2021, the front console ports may only charge, so the glovebox port is the only one that records.
- There is no glovebox port. Record from one of the two front USB ports in the center console. The manual describes them as USB-C compatible. A USB-A stick needs an adapter there. The T7 Shield can use its USB-C to C cable.
The rear USB ports only charge, in every model year.
The USB-A port inside the Model Y glovebox. This is the port for Dashcam and Sentry Mode.
Do not use a hub. The manual says connecting multiple devices through a USB hub can prevent them from being recognized by Sentry Mode and Dashcam.
How the car uses the drive:
| What records | When it saves | Where it lands on the drive |
|---|---|---|
| Dashcam, continuous | While driving, overwritten in a loop | TeslaCam > RecentClips (up to 60 minutes) |
| Dashcam, saved | Tap the Dashcam icon, honk (if On Honk is enabled), or Auto on a safety-critical event | TeslaCam > SavedClips (last 10 minutes) |
| Sentry Mode events | A security event while parked with Sentry on | TeslaCam > SentryClips. The oldest are deleted when the drive runs low. |
| Encrypted clips | When Encrypt Dashcam Recordings is on | TeslaCam > EncryptedClips. Play in the car or at dashcam.tesla.com. |
Each saved clip is six videos, one per camera: front, rear, left, right, left pillar, and right pillar. Without a drive, Sentry Mode still sends an alert to the app, but there is no video.
What the storage drive has to be
The owner’s manual asks for:
- 64 GB minimum. Tesla adds that you should use as much storage as possible because video takes a lot of space.
- 4 MB/s sustained write. The manual points out that sustained write is different from peak write.
- USB 2.0 compatible. A USB 3.0 drive has to support USB 2.0 as well.
- Formatted by the car or on a computer: exFAT, MS-DOS FAT (Mac), ext3, or ext4. NTFS is not supported.
There is no maximum capacity on that list, unlike some other EVs. The only size hint is the overwrite figure: up to 24 hours of footage on drives of 1 TB or more.
The 4 MB/s line is low, and every drive here is rated far above it on paper. The catch is the wording. A flash drive box quotes a peak read. Samsung’s BAR Plus pages say the write speed is lower than the read speed, and they do not give a write number. The T7 Shield publishes a sequential write, and it is an SSD, which is the kind of drive built to take writes for hours.
The glovebox port is USB-A. Both BAR Plus sticks are USB-A and plug straight in. The T7 Shield has a USB-C port on the drive, and the box includes a USB-C to A cable for this port.

Cheapest: Samsung BAR Plus 256GB
Check the Samsung BAR Plus 256GB price on AmazonThe Samsung BAR Plus (model MUF-256BE4) is a metal USB-A stick, 0.61 × 1.58 × 0.47 inches. It plugs straight into the glovebox port with no cable. Samsung lists USB 3.1 with backward compatibility for USB 2.0, which covers the manual’s USB 2.0 line, and up to 400 MB/s read. The product page says write speed is lower than read and does not publish a write figure.
256 GB is four times the 64 GB minimum. Compared with the drive most cars came with, it is a longer stretch of footage before the oldest is overwritten. Samsung rates it to work from 0°C to 60°C (32°F to 140°F) and to survive 72 hours in 1 m of salt water. The warranty is 5 years limited.
This is a flash drive. It is the pick when the stock drive keeps filling up and you mainly save a clip now and then. If Sentry Mode is on most of the time and the car parks in public every day, the SSDs below are built for that much writing.
Mid: Samsung BAR Plus 512GB
Check the Samsung BAR Plus 512GB price on AmazonThe BAR Plus 512GB (model MUF-512BE4) is the same body and the same USB-A plug, with twice the capacity. Samsung lists it as USB 3.2 with up to 400 MB/s read, and again says write speed is lower than read. It still plugs straight into the glovebox port, so there is no cable to route and nothing loose in the glovebox.
Step up to this one when the 256 GB stick would roll over too fast, or when you keep a lot of saved and Sentry clips on the drive. SentryClips is the folder the car trims when space runs low, so more room means older Sentry events survive longer.
Best: Samsung T7 Shield 2TB
Check the Samsung T7 Shield 2TB price on AmazonThe Samsung T7 Shield in 2 TB (model MU-PE2T0S) is an SSD, at double the 1 TB mark where the manual says footage can reach 24 hours before it is overwritten. Samsung rates it at up to 1,050 MB/s read and 1,000 MB/s write on USB 3.2 Gen 2. Those are sequential figures. In the Model Y the port sets the ceiling, and the drive’s write rating is well above the 4 MB/s sustained minimum.
The drive has a USB-C port. The box includes a USB-C to C cable and a USB-C to A cable. Use the C to A cable for the glovebox port in any Model Y that has one, and set the drive in the glovebox. On a 2020–2024 car with only the front console ports, the C to C cable is the one to use. No hub in between.
It is IP65 for dust and water, drop-rated to 3 m, and covered for 3 years. Samsung lists an operating range of 0–60°C. A glovebox in a closed car on a hot day can go past that.
Leave Samsung Magician’s password protection off. The car has to format the drive and write to it. If you want the clips protected, turn on Encrypt Dashcam Recordings in the car instead. The T7 Shield review goes further into the rugged spec, and the portable SSD comparison puts it next to faster 20 Gbps drives. A 20 Gbps drive does nothing extra on a USB 2.0-compatible car port.
Save money: the T7 Shield 1TB
Check the Samsung T7 Shield 1TB price on AmazonThe T7 Shield 1TB (model MU-PE1T0S) is the same SSD at half the capacity. Samsung lists the same 1,050 MB/s read and 1,000 MB/s write, the same 88 × 59 × 13 mm body, the same IP65 rating, the same cables in the box, and the same 3-year warranty. 1 TB is the size the manual ties to its longest overwrite window, up to 24 hours. The 2 TB adds room for saved and Sentry clips on top of that. Pick the 1 TB over the BAR Plus 512GB when you want an SSD and do not mind the drive sitting in the glovebox on its cable.
How to set the drive up
Plug the drive into the glovebox port, or a front console port on a car without one. Then go to Controls > Safety > Format USB Drive. The car formats it as exFAT and creates the TeslaCam folder. Formatting erases everything on the drive, and the option appears only when the drive has one partition or none.
If the car will not format it, use a computer. Format the drive as exFAT, MS-DOS FAT (Mac), ext3, or ext4, and create a top-level folder named TeslaCam. Plug it back in and give the car a few seconds. The Dashcam and Sentry Mode icons should show up in Controls.
Turn on Dashcam under Controls > Safety > Dashcam and pick Auto, Manual, or On Honk. Turn on Sentry Mode under Controls > Safety > Sentry Mode. There you can also exclude Home, Work, or Favorites so Sentry does not run in your own driveway. Tesla notes that power use may increase with Sentry Mode on, and that Sentry turns off if the car enters Low Power Mode.
Before you pull the drive, pause Dashcam. Press and hold the Dashcam icon. That is the manual’s advice to avoid losing footage. To watch clips, use the Dashcam viewer on the touchscreen in Park, the Tesla app, or open the TeslaCam folder on a computer. Move saved clips off the drive regularly. When it fills up, new footage stops saving.
Tesla Model Y USB drive FAQ
Does the Tesla Model Y come with a USB drive?
Most do. The 2025+ manual says the glovebox USB port is equipped with a flash drive, and the 2020–2024 manual says the same for cars with a glovebox port. The reason to replace it is capacity. A larger drive keeps more footage before it is overwritten.
What size USB drive is best for Sentry Mode?
The minimum is 64 GB. The manual says footage can last up to 24 hours on drives of 1 TB or more before it is overwritten, so 1 TB is the practical target. The T7 Shield 1TB or 2TB covers that.
Is there a maximum drive size?
The Model Y manual lists a 64 GB minimum and no maximum.
Can I use a USB hub?
The manual warns against it. A hub can stop the drive from being recognized by Sentry Mode and Dashcam.
What format does the drive need?
exFAT, MS-DOS FAT (Mac), ext3, or ext4. NTFS does not work. Controls > Safety > Format USB Drive formats it as exFAT for you.
Which port does the drive go in?
The USB-A port in the glovebox. On older cars without it, use a front port in the center console. Rear ports only charge.
Why isn't the Dashcam icon showing up?
Check that the drive is in the glovebox port, or a front console port only on a car without one, that it has a TeslaCam folder, that it is not NTFS, and that no hub is in between. If it still does not show up, format it in the car.
Final Verdict
Buy the Samsung T7 Shield 2TB if Sentry Mode stays on and you want to keep months of saved clips. It is an SSD with a published write rating far above the 4 MB/s minimum, and it plugs into the glovebox on the C to A cable in the box. The T7 Shield 1TB is the same SSD for less money, at the size the manual ties to its longest overwrite window.
Buy the Samsung BAR Plus 512GB if you want the drive to plug straight into the port with no cable, and you still want a lot more room than the stock drive. Buy the Samsung BAR Plus 256GB if you mostly save a clip here and there and want the cheapest real upgrade. Both sticks quote a read speed and say the write is lower. The Shield is the one built for recording all day.
