Frequently asked questions
Frequently asked questions
What does price per terabyte ($/TB) mean?
Price per terabyte divides a drive's price by its capacity in terabytes, so a $90 1TB SSD is $90/TB and a $180 4TB SSD is $45/TB. It is the fairest way to compare drives of different sizes, because the cheapest drive is rarely the best value per gigabyte.
How often do prices update?
Prices sync from Amazon several times a day and are stored in our database. Each page shows an 'Updated' timestamp so you can see how fresh the data is. We never scrape Amazon live at page load.
Which Amazon marketplaces do you cover?
The main site covers Amazon.com (US). Country homepages cover Amazon.ca (Canada), Amazon.co.uk (UK), Amazon.de (Germany), Amazon.es (Spain), Amazon.it (Italy) and Amazon.nl (Netherlands), each in local currency.
What is a NAS drive and do I need one?
NAS drives use CMR recording, RAID-friendly firmware (TLER), vibration tolerance and a 24/7 workload rating. For an always-on multi-bay NAS they materially reduce drop-out and rebuild risk versus desktop drives. See our NAS drive listing and guides.
Are renewed and recertified drives safe to buy?
Amazon Renewed and recertified enterprise drives can offer excellent $/TB, especially for cold storage or non-critical bulk. We flag condition on every listing so you can weigh the discount against the shorter warranty.
Do you earn commission?
Yes. As an Amazon Associate we earn from qualifying purchases made through our links. This never affects how drives are ranked, which is purely by the data ($/TB, capacity, condition).
