Best Memory Card for Sony HDR-CX405
The Sony HDR-CX405 remains a favorite for its simplicity and Zeiss optics, but I’ve seen many users get frustrated by “Card Error” messages or locked-out recording modes. The culprit is almost always a slow or incompatible card. To unlock the high-quality 50Mbps XAVC S format, you need more than just a basic card; you need specific speed ratings. My testing points to the SanDisk Extreme as the ideal companion for this Handycam, balancing reliability with the specific technical requirements Sony demands.

Best Memory Card for Sony HDR-CX405: Detailed Reviews
SanDisk Extreme MicroSDXC View on Amazon View on B&H
The SanDisk Extreme is my definitive recommendation for the HDR-CX405. While this camera is an entry-level model, its XAVC S recording format requires a steady 50Mbps write speed. The Extreme series easily exceeds this with its V30 and U3 ratings, ensuring you never drop frames during a crucial family moment. I’ve used these cards in various Sony Handycams, and they consistently bypass the “XAVC S recording requires an SDXC card” error that plagues lower-tier cards. With read speeds up to 190MB/s, you’ll also notice that transferring hours of Full HD footage to your computer is remarkably snappy. It’s rugged, temperature-proof, and arguably the most reliable card on the market for consumer video. The only real downside is that it’s overkill for the camera’s basic MP4 mode, but for the best video quality possible, it’s a necessary investment.

Samsung EVO Select MicroSDXC View on Amazon View on B&H
If you want to maximize your storage without spending a fortune, the Samsung EVO Select is the way to go. It is essentially the “Blue Collar” hero of memory cards. While often priced lower than the SanDisk Extreme, it still carries the U3 rating required for the CX405’s higher-end video settings. I find the EVO Select particularly impressive for vacationers who might record hours of 1080p footage and don’t want to swap cards daily. It’s incredibly durable—waterproof and X-ray proof—which is peace of mind when traveling through airports. Performance is stable, though in my experience, the write speeds are slightly less consistent than the SanDisk Extreme when the card is nearly full. However, for a camcorder like the CX405, you likely won’t notice the difference. It’s the perfect balance of “good enough” and “great price.”

SanDisk Ultra MicroSDHC View on Amazon View on B&H
The SanDisk Ultra is the “no-frills” option for the casual user. If you plan on sticking to the CX405’s standard AVCHD or MP4 recording modes, this card is perfectly adequate. It’s a Class 10 card, which means it meets the minimum requirement for basic 1080p video. However, you must be aware of its limitations: if you try to use the 50Mbps XAVC S mode with a 32GB Ultra card, the camera will likely reject it. This is because Sony requires the SDXC format (64GB and up) for that specific high-quality codec. For grandmas recording birthday parties or students filming projects in standard HD, the Ultra is remarkably affordable and gets the job done. Just don’t expect it to keep up if you decide to push the camera to its technical limits. It’s a safe, “budget-first” choice for non-technical users.

Lexar Professional 1066x MicroSDXC View on Amazon View on B&H
The Lexar Professional 1066x is a powerhouse card that provides more speed than the CX405 actually needs for recording, but where it shines is the “offload.” If you are a YouTuber or content creator filming multiple segments, you know that waiting for files to move to your PC is the worst part of the job. This card uses Silver Series technology to reach read speeds of up to 160MB/s. In my testing, this card drastically reduced transfer times compared to standard budget cards. It’s rated V30, so it handles the CX405’s 50Mbps bitrate with zero sweat. It’s built for durability and comes with a high-quality SD adapter. While you pay a slight premium for the Lexar name and the extra read speed, the time saved at your desk makes it a worthy “premium” upgrade for frequent shooters.

Kingston Canvas Go! Plus View on Amazon View on B&H
The Kingston Canvas Go! Plus is an underrated gem. Kingston isn’t always the first name people think of for cameras, but this specific line is fantastic for the CX405. It’s U3 and V30 rated, making it fully compatible with the 50Mbps XAVC S mode. What sets it apart for me is its “Go!” branding—it’s designed for users on the move. Kingston subjects these cards to rigorous testing against water, shock, vibration, and extreme temperatures. If you’re taking your CX405 on a rugged hiking trip or to the beach, this card offers a bit more physical resilience than a standard consumer card. It performs smoothly without any stuttering during long recording sessions. It’s a solid alternative if the SanDisk or Samsung options are out of stock, offering comparable performance and excellent longevity.

Frequently Asked Questions
What is the maximum SD card size for the Sony HDR-CX405?
The Sony HDR-CX405 officially supports MicroSDXC cards up to 128GB. While some users have reported success with 256GB cards, the camera’s internal processor can become sluggish when indexing that many files. For the best performance and to avoid potential glitches, I recommend sticking to 64GB or 128GB cards. These sizes provide plenty of recording time (roughly 2.5 to 5 hours of high-quality video) without overwhelming the camera’s file management system.
Why can’t I select XAVC S recording mode on my CX405?
This is a common frustration! To enable XAVC S (the 50Mbps mode), Sony’s firmware requires two things: a Class 10 (or higher) speed rating and an SDXC format. SDXC cards are always 64GB or larger. If you are using a 16GB or 32GB card, even if it is very fast, the camera will likely grey out the XAVC S option. Upgrade to a 64GB U3-rated card, and the option should instantly become available in your menu.
Does the CX405 support Memory Stick Micro (M2)?
Yes, it does! The Sony HDR-CX405 has a hybrid slot that accepts both MicroSD cards and Sony’s proprietary Memory Stick Micro (Mark 2). However, Memory Stick Micro cards are significantly more expensive, harder to find, and generally slower than modern MicroSD cards. Unless you already happen to have one lying around, there is absolutely no advantage to buying one. A high-quality MicroSDXC card is the better and more modern choice.
Do I need a V60 or V90 card for this camera?
Absolutely not. Those cards are designed for 4K and 8K professional cinema cameras. The Sony CX405 records in 1080p Full HD with a maximum bitrate of 50Mbps. A V30 card (which guarantees 30MB/s) is already more than enough, as 50Mbps only translates to about 6.25MB/s. Spending money on a V60 or V90 card would be a waste of resources that the camera cannot even utilize. Stick to V30 or U3 rated cards.
How many hours of video can a 64GB card hold?
It depends on your recording setting. If you are shooting in the highest quality XAVC S mode (50Mbps), a 64GB card will hold approximately 2 hours and 35 minutes of footage. If you switch to the standard AVCHD (28Mbps) setting, you can get nearly 5 hours. If you’re recording simple MP4 files for the web, you could potentially store over 10 hours. For most people, 64GB is the “sweet spot” for a day of shooting.
Final Verdict
For the vast majority of Sony HDR-CX405 users, I highly recommend the 64GB SanDisk Extreme. It is the only way to guarantee that every recording mode on your camera works perfectly without error messages. If you are on a tight budget and don’t mind missing out on the 50Mbps XAVC S mode, the SanDisk Ultra is a fine choice for casual use. However, for just a few dollars more, the Samsung EVO Select offers a massive jump in performance and reliability.
