Frequently asked questions
How is the unit price calculated?
We divide the listed price by the capacity stated by the merchant (per terabyte). Shipping is added only when the merchant publishes it.
How fresh are the prices?
Listings are re-read several times a day. Each offer shows its observation time and is removed once it is too old to be trusted.
Which drive for a NAS?
Prefer drives marketed for NAS use, usually CMR recording and rated for 24/7 operation. Desktop drives are fine for occasional backups.
