SSDs: how to choose? A beginner's guide
The SSD is the computer's "storeroom" where the operating system, applications, games and files are kept. It is the SSD that most determines how quickly the computer starts, applications open and game levels load.
In this guide we explain how SATA and NVMe SSDs differ, which technology is faster, how much space your computer needs and which drive is a true gamer's choice.
🎯 Quick answer
| Need | Recommendation | Gigabyte example |
|---|---|---|
| Upgrading an old computer or laptop (instead of an HDD) | 2,5" SATA SSD | Gigabyte SSD 480GB SATA |
| Office computer | 240–480 GB SATA or 500 GB NVMe | Gigabyte SSD 240GB SATA |
| Gaming PC | 1 TB NVMe PCIe 4.0 | Gigabyte Gen4 4000E 1TB |
| Many games, video editing | 2 TB or more NVMe | Several NVMe drives or a higher-capacity model |
Why is an SSD better than an old HDD?
An HDD (hard disk drive) reads data by spinning magnetic platters, so it is slow and sensitive to knocks. An SSD has no moving parts – data is stored in memory chips. As a result, an SSD is many times faster, silent and more shock-resistant.
💡 The best upgrade for an old computer
If your computer or laptop still has an HDD, replacing it with an SSD is the cheapest and most effective way to speed it up. The computer will start in a few seconds and applications will open much faster.
SATA or NVMe? Which technology is faster?
| Type | Form factor | Sequential read speed | Suitable for |
|---|---|---|---|
| HDD | 3.5" or 2.5" | A few hundred MB/s | For archives and large files |
| SATA SSD | 2,5" | Up to ~550 MB/s | For upgrading old computers, office use |
| NVMe PCIe 3.0 | M.2 | Up to a few thousand MB/s | For office and entry-level gaming PCs |
| NVMe PCIe 4.0 | M.2 | Up to ~7,000 MB/s | For gaming and work – the optimal choice |
| NVMe PCIe 5.0 | M.2 | More than 10,000 MB/s | For enthusiasts and professional work |
For example, the Gigabyte SSD 480GB SATA reads at up to 550 MB/s, while the Gigabyte Gen4 4000E 1TB NVMe reads at up to 4,000 MB/s – about 7 times faster.
⚠ Before buying an NVMe drive, check
NVMe drives plug into the M.2 slot on the motherboard. Check that your board has an M.2 slot with NVMe (PCIe) support and which generation it is (PCIe 3.0, 4.0 or 5.0). A newer drive will work in an older slot, just slower. More in the motherboard guide.
How much space does your computer need?
| Capacity | Enough for |
|---|---|
| 240–256 GB | Only for the operating system and essential applications |
| 480–512 GB | For an office and home computer, a few games |
| 1 TB | For a gaming PC – the optimal choice |
| 2 TB and more | For a large game library, video editing, photo archives |
Modern games often take up several tens of gigabytes, and some more than a hundred. In addition, an SSD works best when at least some free space is left on it. That's why we recommend at least 1 TB for gamers.
🎮 A true gamer's choice
For most gamers the best price-to-performance ratio is 1–2 TB NVMe PCIe 4.0 SSD. It's fast, spacious and fits almost all modern motherboards. Our choice – Gigabyte Gen4 4000E 1TB: up to 4,000 MB/s read and 320 TBW endurance.
A popular and convenient solution is two drives: a fast NVMe for the operating system and games, plus an additional SATA SSD or HDD for files.
What else do SSD specifications mean?
| Term | What it means |
|---|---|
| TBW | How many terabytes of data the manufacturer guarantees can be written over the drive's lifetime. For example, the Gigabyte Gen4 4000E 1TB – 320 TBW. For a typical user this is enough for many years. |
| MTBF | Mean time between failures in hours – a reliability indicator. |
| DRAM | Additional cache memory on the drive. DRAM-less drives are cheaper, and for normal use the difference is often small. |
| M.2 2280 | The most common NVMe drive size: 22 mm wide and 80 mm long. |
| TRIM, S.M.A.R.T. | Features that help maintain drive speed and monitor its health. |
Frequently asked questions
Is an SSD suitable for a laptop?
Yes. Check which slot your laptop has: 2.5" SATA or M.2 NVMe.
Will an NVMe drive speed up games?
It will speed up game loading and level loading, but FPS (frame rate) is mostly determined by the graphics card.
Can I have several SSDs?
Yes. Many motherboards have several M.2 slots and SATA ports.
Does an NVMe drive need cooling?
A heatsink is useful for fast PCIe 4.0 and 5.0 drives – many motherboards already have them on the M.2 slots.
