For a general computer, 1TB is the comfortable baseline in 2026 and 500GB the bare minimum. For gaming, 2TB is the sweet spot because modern titles often exceed 100GB each, and 4TB suits large libraries. A useful rule: price per terabyte usually falls as capacity rises, so a larger drive is often better value per gigabyte.
How much capacity by use
| Use case | Best choice | Why |
|---|---|---|
| Everyday laptop / desktop | 1TB | Comfortable for OS, apps and files; 500GB is the minimum today. |
| Gaming | 2TB | Modern games can top 100GB each; 2TB holds a healthy rotation. |
| Large game library | 4TB | Keep dozens of big titles installed without constant deleting. |
| Creative / video work | 2-4TB SSD + HDD | Fast scratch space for active projects, HDD for archives. |
| Bulk / backups | HDD 8TB+ | Capacity per dollar beats SSD; speed is not the priority. |
The capacity sweet spot
Bigger drives are usually cheaper per terabyte, so jumping one size up often costs little more per gigabyte while doubling your headroom. Before buying, compare the price per terabyte of the size you want against the next size up in the live table; the larger drive is frequently the smarter buy.
Don't forget headroom and backups
Leave roughly 10-20 percent of an SSD free for sustained performance and wear levelling, so size up slightly from your raw needs. And capacity is not a backup: keep important data copied to a second drive regardless of how large your main drive is.
The live table below ranks drives on Amazon.com by price per terabyte so you can find the capacity that balances space and cost for your use.
Buying storage in the US
Prices on this page reflect Amazon.com in US dollars. The deepest storage discounts land around Black Friday and Cyber Monday in late November, with Prime Day in July a strong second; outside those windows, day-to-day prices move little during the 2026 shortage.
Returns and warranty are simplest when the listing is sold by Amazon.com or an authorised US seller. For a single critical drive, prefer that over a third-party reseller so the manufacturer warranty applies cleanly.

Frequently asked questions
Is 1TB enough?
For general use, yes; 1TB is a comfortable baseline in 2026. For a large game library, heavy media or creative work, 2TB or more is worth the step up.
How much SSD do I need for gaming?
2TB is the sweet spot, since modern games can exceed 100GB each. 1TB works for a small rotation, and 4TB suits players who keep many big titles installed at once.
Is it cheaper per TB to buy a bigger SSD?
Usually yes. Price per terabyte tends to fall as capacity rises, so a larger drive is often better value per gigabyte. Compare your target size against the next size up in the table.
How much free space should I leave on an SSD?
Keep roughly 10 to 20 percent free. SSDs rely on spare space for wear levelling and sustained write performance, so a drive that is constantly near full can slow down and wear faster.
Do I need a separate drive for backups?
Yes. No matter how large your main drive is, keep a backup on a second drive (or offsite). Capacity does not protect against drive failure, deletion or ransomware.
