What to Look for When Buying Buying Guide
1. Compatibility with MacBook Air 2017
The most critical factor when selecting an SSD for your MacBook Air 2017 is compatibility. Unlike newer MacBooks that use standard M.2 NVMe drives, the 2017 model uses a proprietary Apple SSD form factor—specifically, a custom 8+16 pin connector with a unique physical layout. This means off-the-shelf M.2 SSDs won’t fit without an adapter. Even then, not all adapters are created equal. Some may cause instability, overheating, or fail to be recognized by macOS. Always verify that the SSD and adapter combo you choose is explicitly listed as compatible with the MacBook Air 2017 (Model A1466). Reputable brands like OWC (Other World Computing), Transcend, and Sintech offer verified solutions. Avoid generic adapters from unknown sellers, as they often lack proper firmware support or thermal management.
2. Performance Specifications
Performance is where SSDs truly shine over traditional hard drives, but not all SSDs deliver the same speed. For the MacBook Air 2017, look for drives that support NVMe (Non-Volatile Memory Express) protocol, as these offer significantly faster read/write speeds compared to older SATA-based SSDs. While the 2017 MacBook Air’s PCIe interface is limited to PCIe 2.0 x2 lanes (max theoretical bandwidth of around 1,000 MB/s), modern NVMe SSDs can still push close to that limit—delivering boot times under 10 seconds and near-instant app launches. Pay attention to sequential read/write speeds (aim for 800+ MB/s read and 600+ MB/s write) and random IOPS (Input/Output Operations Per Second), which affect multitasking and system responsiveness. However, don’t overpay for speeds beyond the MacBook’s hardware limits—there’s no benefit to buying a 3,500 MB/s drive if your system can’t utilize it.
3. Storage Capacity Needs
Storage capacity directly impacts how much you can store on your MacBook—apps, photos, videos, documents, and system files. The original MacBook Air 2017 came with 128GB, 256GB, or 512GB options, but many users found 128GB insufficient even at the time. Today, with macOS updates, photo libraries, and cloud sync folders, 256GB is the practical minimum for most users. If you work with large files (video editing, design, development), consider 512GB or 1TB. Keep in mind that SSDs perform best when they have at least 10–20% free space, so a 512GB drive with 400GB used will slow down over time. Also, larger capacities tend to offer better longevity due to wear leveling across more memory cells. Avoid 128GB upgrades unless you strictly use cloud storage and external drives.
4. Build Quality & Durability
SSDs have no moving parts, making them inherently more durable than HDDs, but build quality still varies. Look for SSDs with high-quality NAND flash memory (preferably 3D TLC or MLC over QLC, which wears out faster) and robust controllers. Brands like Samsung, Crucial, and OWC use enterprise-grade components that ensure longer lifespan and better error correction. Check the drive’s TBW (Terabytes Written) rating—this indicates how much data can be written over the drive’s lifetime. A 512GB SSD with a 300 TBW rating is generally sufficient for 5+ years of average use. Also, consider thermal performance. Some third-party SSDs and adapters can overheat during heavy use, triggering throttling or system crashes. Opt for drives with built-in heat spreaders or choose adapters with thermal pads.
5. Brand Reputation & Reliability
Not all SSD brands are trustworthy, especially in the niche market of MacBook upgrades. Stick with well-established names that specialize in Mac-compatible storage. OWC (Other World Computing) is a leader in this space, offering SSD kits specifically designed for older MacBooks, including installation tools, cloning software, and detailed guides. Transcend and Sintech also provide reliable adapters and SSD combos. Avoid no-name brands or sellers with poor reviews—these often use counterfeit chips or outdated firmware that can corrupt data or fail prematurely. Check forums like MacRumors, Reddit’s r/mac, and Apple Support Communities for real user experiences. A reputable brand may cost more upfront but saves you from headaches, data loss, and repeated replacements.
6. Warranty & Support
A solid warranty is a strong indicator of a manufacturer’s confidence in their product. Most quality SSDs come with a 3- to 5-year limited warranty, covering defects and premature failure. OWC, for example, offers a 3-year warranty on their Aura Pro series SSDs for Mac, with free replacement and technical support. Crucial and Samsung also provide excellent customer service and online resources. When buying third-party kits, ensure the warranty covers both the SSD and the adapter. Some sellers offer extended warranties for a fee—consider this if you plan to keep your MacBook long-term. Also, check if the company provides firmware updates, which can improve compatibility and performance over time. Avoid products with no warranty or vague terms.
7. Ease of Installation & Tools Included
Even if you’re technically inclined, upgrading the SSD in a MacBook Air 2017 is not trivial. The process requires disassembling the laptop, removing the logic board, and carefully replacing the soldered SSD—unless you use an adapter that allows for a removable drive. Some kits include everything you need: SSD, adapter, screwdrivers, spudgers, and step-by-step video guides. OWC’s Aura Pro kits are particularly user-friendly, with labeled components and macOS-compatible firmware pre-loaded. If you’re not comfortable with soldering or micro-electronics, consider professional installation. Many repair shops now offer SSD upgrade services for older MacBooks, often with a warranty on labor. DIY saves money but carries risk—damage to the logic board can render your MacBook unusable.
8. Price vs. Value
Price is always a consideration, but the cheapest option isn’t always the best value. A $50 SSD might seem tempting, but if it fails in six months or isn’t recognized by macOS, you’ve wasted time and risked data loss. Conversely, spending $300 on a top-tier drive may be overkill if you only need basic storage. Aim for the sweet spot: a reliable, mid-range SSD from a trusted brand that offers good performance, durability, and support at a fair price. As of 2026, expect to pay $80–$120 for a 256GB upgrade, $120–$180 for 512GB, and $200–$300 for 1TB. Watch for sales during Black Friday, Prime Day, or back-to-school seasons. Also, consider total cost of ownership—some kits include cloning software that saves you $50+ on data migration tools.
