What Hard Drive Should I Buy?
> The drives that just don’t work in our environment are Western Digital Green 3TB drives and Seagate LP (low power) 2TB drives. Both of these drives start accumulating errors as soon as they are put into production. We think this is related to vibration. The drives do somewhat better in the new low-vibration Backblaze Storage Pod, but still not well enough.<p>Another reason to avoid the WD Green 3TB: these drives aggressively put themselves to sleep to save power. It's literally a matter of streaming a video from disk and if the OS caches enough of the file, the drive will see there haven't been any accesses in a few seconds and stop spinning.<p>The video will of course glitch when the cached data runs out and the drive needs to spin up. Great design.
