How to Upgrade Your Mac’s Performance or Storage Through MacSales.com
Updated
MacSales.com (eshop.macsales.com) is an OWC storefront for Mac upgrades and accessories. You can improve a Mac in three practical ways: add memory where your model allows it, expand storage with an internal or external SSD, and improve connectivity with docks and adapters. The site also sells new and certified pre-owned Macs, iPhones, iPads, and Apple Watches, so it can serve as a single stop for both upgrades and replacement devices. Before buying, confirm your exact model’s compatibility and whether the part is user-installable.
What you can upgrade, and what to check first
| Upgrade path | What it changes | Check before ordering |
|---|---|---|
| Memory (RAM) | Multitasking headroom and performance in memory-heavy apps | Exact Mac model and year; whether RAM is soldered or replaceable; required specification |
| Internal storage | Capacity and drive speed on supported models | Model-specific drive compatibility; installation difficulty; warranty implications |
| External storage | Capacity and workflow speed without opening the Mac | Port type and speed (Thunderbolt/USB); whether you need bus-powered portability or a multi-bay desktop unit |
| Docks and connectivity | Port expansion, display connections, power delivery | Ports your Mac provides; displays and peripherals you need to connect |
| Power adapters | Replacement or spare charging | Wattage and connector required by your device |
The site’s own framing is “Upgrade the Performance of Nearly Any Mac,” with configuration choices and savings versus buying new. That “nearly” matters: Apple has soldered RAM on many recent models, so memory upgrades are not universal. Treat the compatibility check as the first step, not the last.
Storage: the most broadly applicable upgrade
Storage is where MacSales.com puts the most emphasis, and it is usually the easiest upgrade to justify. Two routes:
External SSD for Mac Studio and other sealed Macs
The site specifically promotes expanding Mac Studio storage without paying the premium for a factory storage upgrade. It points to the OWC Express 4M2 (high-capacity desktop enclosure) and the portable OWC Express 1M2 80G. The logic is straightforward: buy the Mac with the storage you need for the system and active projects, then put large media libraries, archives, and project files on external drives. You get capacity and real-world speed for less than configuring a larger internal drive at purchase.
This approach suits video editors, photographers, and anyone with large asset libraries. It does not suit people who need everything on internal storage for travel or who dislike managing multiple volumes.
RAID and multi-bay storage for heavier workflows
For sustained throughput and redundancy, the site highlights the OWC ThunderBay 4: four bays accepting 2.5-inch or 3.5-inch drives, speeds up to 1527MB/s, and capacity up to 96TB, listed from $229.00. That class of device fits backup, multi-stream compressed 4K video, and centralized project storage. A single portable SSD is simpler and cheaper for lighter use; a four-bay RAID makes more sense when you need capacity and speed together and can accept desktop-only hardware.
Internal drives
Internal SSD upgrades are model-dependent. Check the specific drive listing against your Mac’s model identifier, and note whether installation requires special tools or a service provider. If your Mac’s storage is soldered, skip this path entirely and use external storage.
Memory, docks, and the rest of the catalog
Memory upgrades deliver the clearest benefit for users running many apps, virtual machines, or large browser workloads, but only on models with replaceable RAM. Verify the exact specification before ordering; the wrong speed or density can prevent booting.
Docks and connectivity products solve a different problem: port scarcity. If you regularly connect displays, card readers, audio interfaces, or Ethernet, a dock can turn a limited-port laptop into a desk setup. Match the dock to your Mac’s fastest available port so you are not paying for bandwidth you cannot use.
The site also stocks power adapters, Apple accessories, and certified pre-owned iPhones, iPads, and Apple Watches, described as OWC-tested and ready to ship. These are replacement purchases rather than upgrades, but they follow the same rule: confirm the model and condition details in the listing.
Upgrade versus buy new: how to decide
Use this comparison on the same dimensions:
- Cost: The site positions upgrades and certified pre-owned devices as savings versus new. Compare the upgrade price against the cost of a new Mac configured with equivalent storage or memory.
- Performance ceiling: RAM and storage upgrades help memory- and storage-bound work. They do not make an older CPU faster. If your bottleneck is processor performance, an upgrade will disappoint.
- Longevity: An upgrade can extend a Mac’s useful life by years if the rest of the machine still meets your needs.
- Risk and effort: Internal installs carry compatibility and warranty considerations. External drives and docks carry almost none.
- Convenience: External storage means managing multiple volumes; a larger internal drive does not.
A reasonable default: if your Mac is otherwise fast enough and you are running out of space or memory, upgrade. If it struggles with CPU-heavy tasks, put the money toward a newer machine.
Ordering checklist
- Identify your exact Mac model and year (Apple menu > About This Mac).
- Open the product listing and confirm compatibility with that model.
- Confirm the port type and speed for external drives and docks.
- Decide between portable and desktop storage based on whether the drive travels.
- For internal installs, confirm the tools and steps required, or plan for professional installation.
- Check the listing for warranty, coverage, and shipping details; the site advertises a year of extended coverage with Mac purchases for US customers, so read the terms that apply to your order.
The main pitfall is buying a part for the wrong model generation. The second is assuming every Mac can be opened and upgraded. Confirm both before checkout, and the rest of the purchase is straightforward.
