How We Research
Every guide on Isolibris starts with one question: will this drive do the job for the person buying it? For a storage drive, that means enough room, a cable that fits your computer and a design that suits where it will live.
Here is how we answer it.
1. We start with what you're storing
A drive for a full computer backup, one for a phone's photos and one that rides in a laptop bag all need different things. A big desktop drive is the wrong pick for travel.
We look at how much you need to store, which computer or phone it plugs into and whether it will sit on a desk or move around. When one of those narrows the choice, we say so.
2. We compare specs and features
We check the drive type (SSD or hard drive), capacity, the speeds the maker gives, the cable and port, the size and weight, and whether it needs its own power. We also note any backup software, password or encryption features, and drop or water resistance.
Samsung, SanDisk, Seagate, WD and other makers describe their drives in their own words, so we name the brand for every claim. We also note the warranty terms the maker gives.
3. We look at owner feedback
We read what owners report after weeks and months of use. We look for patterns, like drives that disconnect, slow down on big copies, run hot or arrive smaller than the label says.
One unhappy owner doesn't sink a drive. A pattern does.
4. We score each drive
Our score weighs specs, features and owner feedback against what that guide's reader needs. A drive that's great for travel may score lower in a guide about long-term backups.
Scores spread out on purpose. A 10 is rare.
5. We keep pages current
Drive makers often sell several sizes and versions under almost the same name. We check the model number and capacity for each pick, and we only link new drives, never renewed or used ones.
We skip unknown brands with no track record. When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every drive we cover.
Any drive can fail, new or old. Keep at least two copies of anything you can't replace, such as one on a drive and one in the cloud or on a second drive.
