Get a 128GB or 256GB SanDisk High Endurance or MAX Endurance microSD card. Kenwood DRV-A601W / DRV-A501W / DRV-A301W Dash Cam uses a microSD Card rated U3 / V30. Dashcams run hot on the windscreen and overwrite video non-stop—always use an 'Endurance' card so it doesn't fail when you need footage.
The official maximum supported capacity for Kenwood DRV-A601W / DRV-A501W / DRV-A301W Dash Cam is 256GB – 512GB (tested up to 512GB). For the best balance of price and reliability, our recommended sweet-spot size is 128GB.
Single camera: 64GB ≈ 8 hrs (1080p) / 4 hrs (4K) • 128GB ≈ 16 hrs (1080p) / 8 hrs (4K) • With Rear Camera (dual-channel): 64GB ≈ 4 hrs • 128GB ≈ 8 hrs • 256GB ≈ 16 hrs. Choosing 128GB gives plenty of headroom without overpaying.
Never use non-endurance cards in dashcams—choose SanDisk High Endurance or MAX Endurance. Standard consumer cards (such as SanDisk Ultra) are not built for continuous loop recording and wear out quickly. Crucially, Western Digital's official warranty terms explicitly exclude dashcam and surveillance use on standard consumer cards (only dedicated High Endurance and MAX Endurance models are covered by warranty). Modern dashcams perform strict write-speed checks and beep continuously if a slow card is inserted.
Setup requirement: Format inside the Dash Cam on first use. For best results, format a brand-new card directly inside the Kenwood DRV-A601W / DRV-A501W / DRV-A301W Dash Cam settings menu upon first installation to establish the correct cluster size for continuous loop recording. We recommend reformatting every 3–4 weeks to clear protected event files.
Yes. Unbranded or counterfeit marketplace cards frequently spoof their capacity or fail to sustain U3 / V30 write speeds, leading to corrupted recordings or 'Card Error' warnings. Stick to genuine, branded cards from a reputable retailer to ensure full manufacturer warranty coverage.
