One 10TB NAS drive, in decimal units (1TB = 1,000GB), before file-system and RAID overhead. Each line is a division you can redo; the per-file sizes are our assumptions and say so.
Security cameras, recording continuously: 289 camera-days - 8 cameras for 36 days. The arithmetic: 3.2 Mbps ÷ 8 = 0.4 MB/s × 86,400 s = 34.56 GB per camera-day; 10,000 GB ÷ 34.56 = 289 camera-days. The bitrate is WD's reference figure for one stream (single stream, 1080p, h.265, 25fps), from WD Purple / WD Purple Pro data sheets (footnote 3); the 8-camera count is our example. A camera set to a higher bitrate fills the drive proportionally faster.
Guides for this capacity: best 10TB hard drive · the HDD price forecast · fill a NAS at today's prices
Every listing we track at this size - 12 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
We can currently price 20 in-stock 10TB NAS drives from 2 brands (WD and Seagate). The best rate is $33.00 per terabyte, against a $46.00 median across the same capacity - a spread worth noticing, because at this size the gap between the cheapest listing and the middle of the market is real money rather than rounding. The lowest ticket price on a single drive is $330.
The listings split 10 new and 10 recertified, and for a NAS that distinction carries more weight than it does in a desktop. An array runs its drives continuously, so the warranty behind each one is a live concern rather than a formality - new carries the manufacturer's, recertified carries a reseller's, and the discount is the compensation for that difference. Our recertified guidance covers what to check before a drive goes into a pool.
A NAS buyer is choosing a configuration rather than a drive, and the number that decides it is usable capacity after parity. At 10TB per drive that works out as follows, before filesystem overhead and before you leave the headroom a pool needs to stay healthy:
Those totals are drives only. The enclosure, the memory and the drive bays you leave empty for a future expansion are separate costs, and the last of those is the one people forget: filling every bay on day one means the next upgrade is a full replacement rather than an addition. Our RAID planner works through the configurations properly, and replacing drives with larger ones covers the upgrade path when you get there.
All 7 in-stock 10TB drives we can verify use conventional recording, which is what an array needs. Shingled drives overlap their tracks to gain density, and the cost of that is rewrite behaviour that can turn a RAID rebuild into a multi-day event or make it fail outright. At this capacity the stock we track is clean. 13 further listings have no recording technology recorded, and those render as unverified rather than assumed.
Warranty terms in stock run 3 to 5 years, and workload ratings run 180 to 550TB per year. That rating is the manufacturer's statement about sustained annual writes, and a NAS serving a household rarely approaches it - it matters when the array is a backup target or a surveillance recorder rather than a media library.
At 10TB rebuild windows are short enough that single parity remains defensible in a small array, which is the main practical advantage this rung has over the larger ones. The trade is the opposite one: more drives for the same total capacity means more bays consumed, more power drawn, and more units that can fail.
The general rule is that cost per terabyte improves as you go up the ladder until it does not, and where it stops improving moves with the market rather than sitting at a fixed capacity. Comparing the live rate on this page against the neighbouring rungs is the only reliable way to find that point on the day you are buying.
The cheapest in-stock 10TB NAS drive we track works out at $33.00 per terabyte. Prices refresh about once a day, so the table above is the current answer rather than this sentence.
30TB in RAID 5, 20TB in RAID 6, and 20TB in RAID 10, before filesystem overhead. RAID 6 costs you one more drive of capacity and buys the ability to survive a second failure during a rebuild.
Every in-stock 10TB listing we can verify is conventional recording, which is what an array needs. Any shingled drive that appears is badged SMR in the table.
They are widely used for exactly this, but the warranty comes from a reseller rather than the manufacturer, and drives bought together from one batch can age together. Verify on arrival rather than on the listing, and consider mixing sources across the array.
Going up a rung usually improves cost per terabyte, but only up to a point that moves with the market. Compare the live rate here against the neighbouring capacities before deciding — at 10TB the advantage you have is shorter rebuilds.
