RAM vs SSD: Which Upgrade Boosts PC Speed More?

You probably rely on your personal computer daily to work, create, communicate, and be entertained. Over time though, PCs inevitably slow down as newer and more demanding applications launch. Upgrading RAM or switching to a solid state drive (SSD) storage can regain lost speed. But which bump delivers the bigger boost?

This guide will demystify computer memory types, show real-world speed comparisons, and provide upgrade tips tailored to your needs and budget. Let‘s level set what RAM and SSDs actually do before diving into nitty gritty benchmarks.

Back to Basics: What is Computer Memory?

At the most basic level, all computers require memory – the hardware that stores data for processing and retrieval. Think of memory as the workspace where active information getting manipulated like documents, browser tabs, game textures, spreadsheets and everything else lives. Information not actively in use gets saved to storage for later access.

There are two broad memory types:

RAM: Stands for Random Access Memory. This is the ultra high-speed volatile working memory your PC uses to run applications, games, websites – basically everything you actively use. Without enough RAM, things crash or slow to a crawl as swap files save/restore data from storage.

Storage: Non-volatile memory that preserves data whether powered on or off. Your operating system, programs, personal files and everything else permanent resides here. Spinning hard disk drives (HDDs) were the old standard but solid state drives (SSDs) took over in the 2010s with radical speed boosts. Storage capacity ranges from 120GB to 16TB+ these days.

Now let‘s contrast how RAM and SSDs differ…

Comparing RAM vs SSDs

While both crucial, RAM and SSDs are optimized very differently:

Let‘s break this down:

RAM – Designed for lightning quick data access crucial for smooth computing. RAM temporarily Juggles open apps, browser tabs, game textures, and other working data at nanonsecond speeds. Downsides? RAM is relatively expensive per GB and contents vanish when shut off losing open work unless hibernated.

SSDs – Engineered around affordably storing massive amounts of files, apps, media long term. Modern SSDs utilize solid state flash memory rather than HDD platters and heads. Prices keep dropping while maximum capacities keep growing. SSD durability and speeds continue improving dramatically too.

Now we‘ll explore speed metrics helping quantify real-world performance.

What Makes RAM and SSDs Fast?

You can‘t tell much about speed from basic specs like capacity or interface. Evaluating memory requires drilling into specialized performance metrics:

For RAM, two core metrics determine real-world speed:

Clock Speed – Measured in MHz, this signifies how many read/write cycles the RAM executes per second. Newer DDR4 RAM hits 3200MHz+ speeds vastly outpacing predecessors.

CAS Latency – The brief delay between issuing a data fetch command and receiving the information, quantified in clock cycles. Latency ranges between 14 and 22 cycles for most DDR4 RAM kits.

For SSDs, metrics like sustained throughput and responsiveness reveal performance capabilities:

Sequential Read/Write Speed – The rate continuously reading or writing very large, uninterrupted data blocks in MB/s. Impacts transferring big files.

Random Read/Write Speed – The rate fetching or saving small bits of non-sequential data. Responsiveness doing this work affects general OS/application "snap".

IOPS – Input/Output Operations per second. At small queue depths this highlights responsiveness spitting out tiny random data transactions.

Now let‘s explore reliability and lifespan at a high level.
