Comprehensive Guide to External SSDs for Mac: Maximizing Storage and Performance While Saving Money

Summary:

This video explains how external SSDs offer a cost-effective and flexible solution to Apple's expensive and non-replaceable internal Mac storage. It covers three main categories of external SSDs:

Cost of Internal Storage Upgrade on Mac [Image 1 at 0:17]: Upgrading internal storage can be very expensive, adding hundreds to thousands of dollars to the Mac's price.
USB 3.2 SSDs (Gen 2 / 10Gbps): These are budget-friendly options ($50-$150) like the Samsung T7 and Crucial X9 Pro [Image 52 at 2:16], offering real-world speeds of 650-950 MB/s [Image 57 at 2:56]. They are suitable for most users, featuring durable aluminum builds for heat dissipation [Image 79 at 4:09] and low power consumption (under 4 watts) [Image 84 at 4:33], ideal for MacBooks on battery power. DIY enclosures combined with NVMe drives can achieve similar speeds at a lower cost [Image 95 at 5:13]. These are great for tasks like editing RAW photos, basic video editing, playing games, and compiling code [Image 60 at 3:17][Image 61 at 3:24][Image 62 at 3:33]. The video also demonstrates connecting an external SSD for file transfer [Image 12 at 1:44]. For iPhone 15 Pro, the drive must be formatted as exFAT for external recording [Image 126 at 6:21], while Time Machine requires APFS or HFS+ [Image 131 at 7:03].
Thunderbolt 4/USB4 SSDs (40Gbps): Priced higher (around $200-$300 for 1TB) [Image 173 at 9:52], these external enclosures with NVMe drives provide impressive speeds of 3000-3500 MB/s [Image 174 at 9:54]. They are perfect for demanding tasks like 4K video editing, compiling code, and running intensive applications directly from the drive [Image 166 at 9:34][Image 169 at 9:43], often matching or exceeding base model internal Mac SSDs [Image 217 at 12:21]. Higher power draw (6-7 watts) [Image 187 at 10:39] means older MacBooks might need a powered hub.
Thunderbolt 5 SSDs (80Gbps): The fastest and most expensive option, these can achieve over 6000 MB/s write speeds [Image 216 at 12:17]. Currently requiring Thunderbolt 5 compatible Macs, they offer performance surpassing even high-end internal Mac storage [Image 218 at 12:24] for professionals needing ultimate speed. The Acasis TB501 enclosure is highlighted [Image 205 at 11:43]. The video emphasizes selecting appropriate file systems (APFS for Time Machine, exFAT for cross-platform compatibility) and considering heat management for drive longevity, showing thermal images of drives under load [Image 219 at 12:27].
