Friends, I'm confused about choosing between HDD and SSD. I'm in the Faculty of Engineering and will constantly work with heavy files like projects, simulations, and CAD files. HDDs are cheap and high-capacity, while SSDs are fast and durable. Which one would you prefer? Is cost more important, or performance? What's your approach?
HDD vs SSD: Which one for university projects?

Hmm, interesting situation... Well, when constantly opening and closing such large files, does the speed of an SSD really make the job easier? Or should we prefer an HDD for its capacity instead?
While HDDs offer price advantages in capacities of 1-2 TB, if you're constantly working with CAD and simulation files, their download/upload/read/write speeds become a serious bottleneck. For example, opening a 50 GB simulation file on an HDD takes 2-3 minutes, whereas the same file can be downloaded in 15-20 seconds on an NVMe SSD. The efficiency gap between the two is nothing short of having to constantly halt your workflow and wait.
The most logical approach is to use both together: a 1 TB NVMe SSD as your system drive (Windows + frequently used programs + active projects) and a 2 TB 7200 RPM HDD as your data storage (old projects, backups, archives). This way, you can balance performance and capacity. For instance, install the SolidWorks beta version on your SSD and store your 20 GB assembly files on the HDD, copying them to the SSD when needed.
Go for an SSD without hesitation if your budget allows. I remember when I was in university, I tried running some FEA simulations on an old 5400 RPM HDD—it took ages to open HDF5 files, and anything with mesh data was a nightmare. I switched to a 500GB SATA SSD on my ThinkPad, and the same projects loaded in under 30 seconds.
If money is tight, at least grab a used SATA SSD off eBay or look for combo deals (laptop + SSD package). A 256GB SSD for the system, programs, and active project files, and let the HDD handle archival storage—this keeps boot times fast and you avoid constantly rewriting the HDD.
It makes sense to compare HDDs and SSDs to different workhorses: an HDD is like an old reliable Toyota Hilux in a farm—cheap, dependable, can handle any volume, even tons of data, but it accelerates slowly and can stall (or, in our case, fail from a drop) at the slightest jolt. Meanwhile, an SSD is a high-speed bike with a turbocharger: more expensive, but you’re flying like you’re on wings, and even if you drop it from the third floor, it won’t break (SSDs have shock and vibration resistance orders of magnitude higher).
From an architectural standpoint, HDDs have spinning platters and magnetic read/write heads—like a turntable in the streaming era: there’s mechanics, there’s wear, and there’s a speed limitation (7200 RPM is decent, but still no match for an SSD). On the other hand, an 8TB HDD will cost 2-3 times less than a pair of 2TB SSDs in RAID 0. If we’re talking about storage for archives, backups, or massive CAE simulations where capacity trumps speed, an HDD is the choice for years to come.
But if you’re running Altium Designer, firing up ANSYS, or working with large CAD files, an SSD delivers a 10x real-time boost. NVMe SSDs (PCIe 4.0) hit speeds of 7000+ MB/s, meaning your projects open in seconds instead of minutes. Plus, SSDs have no moving parts—so less noise, less heat, and less risk of failure from jostling in your backpack. Yeah, they’re pricier, but when you factor in the time you save waiting for loads, they pay for themselves fast.
