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.

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.
