So you want to upgrade your PC‘s memory, but confused whether RAM or an SSD is the way to go? You‘re not alone!
While both essential, RAM and solid-state drives serve different roles. Your RAM gives applications a place for short-term storage and quick access to needed data. SSDs replace old-school hard drives for non-volatile long-term storage of all your files, games, and media.
Upgrading each component impacts your system in very different ways. Before spending your hard-earned cash, let‘s clearly understand what makes RAM and SSDs tick!
Peering Inside RAM
Your PC uses RAM, or random access memory, as temporary storage for currently running apps. Think of it like your computer‘s short-term memory – when you open Photoshop, Chrome or Call of Duty, relevant data gets copied from slower storage into faster RAM.
This provides essential breathing room for your CPU to work without constantly fetching data from a hard drive. More RAM means more applications can run simultaneously without competing for that precious workspace.
For example, RAM capacity directly impacts how many browser tabs you can keep open:
| RAM | Tabs Open |
|---|---|
| 4GB | 10-15 |
| 8GB | 20-25 |
| 16GB+ | 30+ |
Upgrading RAM isn‘t about speed per se – it‘s about multitasking muscle. Extra memory lets you hoard more Chrome tabs, edit giant Photoshop files, or run an intensive game smoothed out by ample memory reserves.
What Makes RAM Fast?
Two key specifications indicate RAM‘s speed:
- Clock speed – Rate of access cycles per second (MHz/GHz)
- CAS Latency – Delay before requested data gets served (cycles)
Today most desktops use speedy DDR4 RAM. Comparing DDR4 vs outdated DDR3, the speed doubles:
| Specification | DDR3 | DDR4 |
|---|---|---|
| Clock Speed | 1600MHz | 3200MHz |
| CAS Latency | 11 | 16 |
Faster RAM guarantees snappier response when pulling needed data into memory for hungry apps. Upgrading makes sense if your rig still runs DDR3 RAM!
SSDs: Faster, Durable Storage
Solid state drives (SSDs) provide non-volatile permanent storage as a speedier replacement for traditional mechanical hard drives. SSDs have no moving parts – data gets written to flash memory chips instead of magnetic platters.
This translates to a 5x or greater speedup for saving and loading files! Check out these real-world game load time improvements:
| Game | HDD (SATA) | SATA SSD | NVMe SSD |
|---|---|---|---|
| Doom | 105 sec | 25 sec | 14 sec |
| COD: Black Ops 4 | 75 sec | 33 sec | 20 sec |
Upgrading an old hard disk drive (HDD) to any solid state drive delivers a massive speed boost. NVMe SSDs connected via PCIe provide the fastest speeds, but SATA SSDs already run laps around HDDs.
Beyond raw speed, SSDs consume less power and prove far more durable with higher tolerance to dust, movement and vibration. Without mechanical parts, they simply fail less often – up to nearly twice as reliable. According to Backblaze‘s stats, ~1.5% of SSDs die annually vs 2.7% of laptop HDDs and a dismal 5.1% for desktop HDD models!
So if you still have a computer running an HDD, migrating to an SSD should be your #1 priority upgrade!
Key Differences Summarized
While both forms of flash memory, properly comparing RAM and SSDs remains an apples-to-oranges errand.
Fundamentally, they play completely different roles in your PC:
- Volatility – RAM contents erased on every reboot, SSDs retain data after power cycles
- Purpose – RAM temporary working memory, SSDs permanent file storage
- Speed Metrics – RAM uses clock rate and latency while SSD benchmarks rely on transfer rates and IOPS
Upgrading Your Memory
- Adding RAM increases background workload capacity via better multitasking muscle
- An SSD accelerates saves, boots and loads by 5-10X over mechanical hard drives
- Further SSD upgrades require understanding technical factors like PCIe vs SATA interfaces to guarantee genuine speed gains!
In the end, more RAM lets you pile additional workload onto your PC at once while SSDs provide a snappy responsive feel when installing programs or accessing files. The best approach is to max out RAM capacity according to your motherboard, then invest in the best SSD you can afford!
