  1. Does this mean when using Dell H330 with SAS 6Gb drives, I'll see significant performance improvement against my existing H310, with SATA 2 and 3 drives when copying data from Cache (SSD) to Array? My reasoning is SAS 6GB capable of 230 MBps while SATA spin drives can only do 100-170 MBps only?
  2. Thanks for the link. Indeed, this paper gives a good explanation of what is the limit of each device, lanes. Thanks for pointing this out. Sent from my iPhone using Tapatalk
  3. still, thanks @LammeN3rd and @johnnie.black!
  4. hahaha, it's truly tricky 😁 I hope I can somehow comprehend this when the time comes for me to upgrade
  5. Let me try to see if I get this If drives are connected to the controller directly, they get the most out of the drive's speed directly. It's only when you use an expander, that will split the bandwidth (if that is what we call it), and in old controllers, use the speed of the slowest device, will using an H330 benefit, since it has that LSI technology.
  6. so if using 6Gb sas drives, and SATA 3 drives, is there reason to upgrade from SAS2008 to H330?
  7. Thanks @LammeN3rd, will read more on this. You've been very helpful.
  8. Can you explain this a bit? How are those drives used in unraid? Array? I thought adding more drives (per share) won't provide any added speed benefit? Please correct me if I'm wrong. Very interested in this.
  9. What is an expander exactly? Apart from this hba controller, expander have other functions? What does it look like? Sent from my iPhone using Tapatalk
  10. I thought even with a faster controller and faster drives, it still won't perform any faster than the 6 Gbps of sata 3, or maybe not even reaching sata 2 speeds? Sent from my iPhone using Tapatalk
  11. Hi. Wondering why get these over perc h310, sas 6g, up to 8 drives I believe. Sent from my iPhone using Tapatalk

    new SAS drive won't spin down

    I wonder how much additional power per drive will it be using? That's the only concern, hope someone can share. Sent from my iPhone using Tapatalk

    new SAS drive won't spin down

    So doesn't sas drives spin down? Starting to consider 3TB sas drives on ebay. My 2 TB drives SATA are starting to fail 1 by 1. They are old already.
