Hello experts,

I have 15 hdds with data on it that a need unfrequently so i don't want to have them all hooked up and eating power all the time.

I'm currently using a ViPower Swaprack system to connect the HDD I need to my system. My model has a SATA host interface and a PATA drive interface so i can hotplug IDE-drives. So far so good.

Since the cost of sata drives dropped below the ide ones i need a storage system that allows me to swap and hotplug ide and sata drives with a sata host interface.

Thanks for any ideas

That would be a possibility but i need a solution with some sort of enclosure to protect the drives.

I dont bother as 2 taped together protect each others interface boards, but if you want USB HDD cases they are available from 1 HDD to many HDDs & start from $20.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Until now i made the observation that usb 2.0 only allows for about 30 mb/s transfer which is about half of what I get with a current solution. Furthermore I'd like to use the Native Command Queueing capability of SATA drives.

If there is no swap-system solution i'll probably have to buy eSATA cases

A server may interest you otherwise a multi HDD enclosure.
HDDs are protected fine if 2 are taped together to protect each others interface boards.

I must go out.

"Until now i made the observation that usb 2.0 only allows for about 30 mb/s transfer "
Wrong
USB 2.0 allows up to 480mb/s transfer

HDD: RPM / cache /  transfer speed
May allow less

Thats:
(480Mbps=Megabits & not MegaBytes per second=about 48MBps).

And thats without protocol overhead (which eats up to 40% depending on drive usage) and if you are using only one device per usb host conroller. Also most (s)ata-usb-bridges don't allow the full 480mbit on the usb side.

The fact remains: i have never seen a disk at it's full potential using USB 2

True, I just was giving some extra info, thinking you had MBps &Mbps mixed up.
