I have a Synology that needs more storage. Thoughts on WD vs Seagate?
I’ve always bought WD Red, but with the recent WD controversies (including the SMR/CMR scandal and the recent WDDA warning), I’m considering Seagate. Also, I can’t find any difference between the IronWolf Pro and Exos drives. What am I missing?
| Metric | Seagate IronWolf Pro 20TB | Seagate Exos X20 20TB | WD Red Pro 20TB |
|---|---|---|---|
| Spindle speed (RPM) | 7200 | 7200 | 7200 |
| Internal transfer rate | 285 MB/s | 272 MB/s | 268 MB/s |
| Gas | Helium | Helium | ??? |
| Cache | 256MB | 256MB | 512MB |
| CMR? | Yes | Yes | Yes |
| MTBF (hours) | 2.5m | 2.5m | 2.5m |
| Non-recoverable errors per bits read | 1 in 10^15 | 1 in 10^15 | 1 in 10^15 |
| Load unload cycles | 600k | 600k | 600k |
| Workload rate (TB/yr) | 550 | 550 | 550 |
| Annualized Failure Rate (AFR) | 0.35% | 0.35% | ??? |
| Warranty | 5yr | 5yr | 5yr |
| Price | $349.99 | $329.99 | $379.99 |
Also, please don’t recommend shucking (those drives are in external enclosures because they didn’t pass QC to become internal HDDs).
says the guy lighting a cigar at the oil refinery… :)
in all seriousness, look at used HGST (western digital) drives many times you can find good deals on drives that where hotspares most of their life at almost 1/2 msrp. if you need new drives stay with the enterprise variants.
I have not heard good things about recent seagate consumer drives.
WD/HGST gold drives have been rock solid at work. (wd purchased HGST and the ‘helium’ line up is almost all just rebranded HGST.)
also, don’t count out toshiba drives. they are a ‘smaller’ company in the us/europe but they make decent drives in my experience.
