So it’s just one stacked on top of the other. Presumably, then, the competitor product is two hard drives. Is this /much/ cheaper? Presumably better for rack space. Power consumption? Does it even matter that it uses one fewer connector?
It’s going to be a hell of a time telling the file system to stripe across drives for redundancy but not /these two/.
- tw04 2y agoWhy would you assume the disk is presenting itself as two drives rather than one and handling the logic internally?
- RantyDave 2y agoI stand corrected. The FAQ mentions appearing as two LUN's but only in the SAS version. https://www.seagate.com/content/dam/seagate/migrated-assets/www-content/solutions/mach-2-multi-actuator-hard-drive/files/sc702.2-2101us-mach-2-faq.pdf https://www.seagate.com/content/dam/seagate/migrated-assets/...
- _yb2s 2y agoI imagine if you stripe across multiple drives that are all actually smaller striped arrays internally but each emulating single drives with firmware, you still get multiplicative speed increases, e.g. a raid 0 with two of these is 4x as fast, and still just raid 0 to the raid controller. I’m not really sure how that is actually better than twice as many regular drives either.
