Quick answer
Storage tools convert storage units (decimal and binary), estimate how much space files need and how long an SSD lasts from its TBW rating, and convert between TBW and DWPD.
Storage Tools gathers everything on ComputingSkill.com related to figuring out storage — how much space you actually have, how long a drive is likely to last under your usage pattern, and how to convert between the units drives, operating systems, and file managers report differently. If you've ever been confused about why a "1TB" drive shows up as roughly 931GB in Windows, or wondered whether your SSD's write endurance rating is something to actually worry about, this is the section for that.
Two of these tools focus on SSD endurance: the SSD Lifespan Calculator estimates how many years a drive might last given your typical daily writes, and the SSD TBW Calculator converts between the two endurance ratings makers publish, DWPD (drive writes per day) and TBW (terabytes written), so drives of different sizes can be compared. The other two are general-purpose: the Storage Calculator helps you plan how much capacity you need for files, backups, games or media libraries, and the Data Storage Converter handles unit conversion between bytes, KB, MB, GB, TB and their binary (KiB/MiB/GiB/TiB) counterparts.
If you want background on the drives themselves rather than just the math, the SSD and HDD hardware pages explain how each storage type actually works, what specs matter when buying one, and how to decide between them.
Which One Do You Need?
Which storage tool answers your question:
- Will my files, games or backups fit on this drive? Storage Calculator
- How many GB in a TB, and why Windows shows less? Data Storage Converter
- How many years will my SSD last at my daily writes? SSD Lifespan Calculator
- A drive lists DWPD, another TBW: how do they compare? SSD TBW Calculator
- Is an NVMe drive worth it over SATA? NVMe vs SATA
- SSD or hard drive for this job? SSD vs HDD
Game installs are a common reason to plan space: each game requirements page lists the publisher’s install size.
Frequently Asked Questions
Should I worry about my SSD wearing out?
For most everyday and gaming usage, modern SSDs are rated for enough total writes that they’ll likely outlast the rest of the system before write endurance becomes a real concern. If you do heavy, sustained write workloads, the SSD Lifespan or SSD TBW calculators can give you a rough sense of where you stand.
Why does my drive show less space than the number on the box?
Manufacturers typically advertise capacity using decimal units (1TB = 1,000,000,000,000 bytes), while operating systems often display capacity using binary units (1TiB = 1,099,511,627,776 bytes) but label it “TB.” The Data Storage Converter can show you both figures side by side.
Which tool tells me if my files will fit on a drive?
The Storage Calculator: enter an average file size, how many files, the drive’s capacity and what is already used, and it shows whether they fit and how much space is left. The Data Storage Converter only converts between units, including the binary GiB and TiB figures Windows shows.
