Toshiba N300 vs Synology HAT3320-8T vs WD Red Plus (8 TB)
Compare three exact 8 TB CMR NAS drives by workload rating, spindle speed, cache and purchase route.
The decision in brief
How the options differ
All three selections are 8 TB CMR SATA drives with 3-year limited warranties. Toshiba and Synology list 7,200 rpm and 512 MB of cache; WD80EFPX lists 5,640 rpm and 256 MB. Synology's datasheet gives HAT3320-8T 300 TB/year, against 180 TB/year for the other two. No reliability or compatibility winner is established.

The buying guide
Package and specification details
Read the workload rating from the exact column
Synology's datasheet gives HAT3320-8T 300 TB/year, although its Plus Series highlights say 180 TB/year. Toshiba lists 180 TB/year for HDWG780XZSTA and WD lists 180 TB/year for WD80EFPX. These are intended-use ratings, not lifespans or write allowances, and a higher figure does not replace a backup.
The Toshiba HDWG780XZSTA column and the Synology HAT3320-8T column both list 7,200 rpm, 512 MB cache, 281 MB/s typical sustained transfer and 755 g. Their workload ratings differ, and neither source says they share hardware, so treat them as separate parts. WD80EFPX lists 5,640 rpm, 256 MB and up to 215 MB/s. Published maxima are not NAS benchmarks.
Toshiba lists the 8 TB N300 for up to 8 drive bays and points buyers to the NAS maker's compatibility list; Synology delivers firmware for its drives through DSM. The Toshiba route is a US marketplace listing with several new offers, and the Synology route is a US reseller listing, so confirm the seller, condition and warranty eligibility. No exact NAS and firmware pairing is established here.
No. HDWG780XZSTA appears in Toshiba's standard N300 specification sheet. The N300 Pro line has different workload and warranty ratings, which must not be applied to it.
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.
