The headline feature is undeniably the speed. The Lexar ES3 1TB External leverages USB 3.2 Gen 2 (10Gbps), a significant leap over older USB 3.0/3.1 Gen 1 (5Gbps). This bandwidth allows it to achieve its advertised speeds: up to 1050MB/s read and 1000MB/s write. In my testing, I consistently achieved real-world speeds of 950-1020MB/s read and 880-950MB/s write when connected to a USB 3.2 Gen 2 port (like on my MacBook Pro M2 and a Windows PC with a Gen 2 port). This is 10-20x faster than a standard external HDD and 2-3x faster than many USB 3.0 SSDs.

Real-World Benefits:

• ✅ iPhone 15 Video Offload: Transferring a 5-minute 4K60 ProRes video (~12GB) took just 13 seconds! This is transformative for content creators who shoot long videos. No more waiting minutes for transfers.
• ✅ Large File Transfers: Copying a 50GB folder of mixed files (videos, photos, documents) to my laptop took 52 seconds, compared to over 2 minutes with a USB 3.0 drive.
• ✅ PS5 Game Transfers: Moving a 50GB game from the PS5 internal SSD to the Lexar ES3 1TB External took ~55 seconds.

❌ Cons:

❌ Speed Limited by Host Port (USB 3.0/2.0, Older Macs): To achieve the full 1GB/s+ speeds, you must have a USB 3.2 Gen 2 (or higher) port. On slower ports (USB 3.0/5Gbps, USB 2.0, or older Macs with Thunderbolt 2/USB-A), speeds will be significantly lower (300-400MB/s for USB 3.0, 40MB/s for USB 2.0). This is a limitation of the interface, not the drive itself, but it’s important to be aware of.

❌ Not Compatible with iPhone 14 or Older (Lightning Port): The direct USB-C connection is a major advantage, but it’s only available for iPhone 15 series and newer. iPhone 14 and older users with Lightning ports will need a USB-C to Lightning adapter (which may reduce speed) or a different drive.

❌ Software-Based Encryption (Slight Performance Impact): While the 256-bit AES encryption is strong, it’s implemented in software (not hardware). This means there might be a very slight performance reduction when accessing encrypted files compared to unencrypted ones. In my testing, the difference was negligible, but it’s a technical limitation compared to hardware-encrypted drives.

❌ No Hardware Write Protection or Physical Lock: Unlike some professional-grade drives, it doesn’t have a physical switch to prevent accidental data deletion or a hardware lock. This is more relevant for highly sensitive environments, but it’s a minor omission for most users.

❌ Short Included Cable (20cm): The included USB-C to USB-C cable is only 20cm (8 inches) long. This is perfect for connecting to laptops and consoles but might be too short for some desktop setups or when using it with a phone on a tripod. You may need to purchase a longer cable separately for certain use cases.

Context for Cons: The cons are relatively minor and largely contextual. The speed limitation is inherent to USB standards, not a flaw in the drive. The iPhone 14 incompatibility is a consequence of Apple’s port change. The software encryption is standard for drives at this price point. The lack of hardware write protection is common. The short cable is a minor inconvenience for most. These cons don’t detract significantly from the overall excellence of the Lexar ES3 1TB External.
