Posts Tagged ‘hard disk drives’

I thought I would update an old series of posts I had about hard disk drive selectors. The previous solutions I had covered were all for IDE drives. Although you could buy adapters for them to work with SATA drives it isn’t worth the effort in my opinion. Indus Technologies does make SATA selectors that allow up to 4 drives, but they are quite expensive (their cheapest model is $179.95). Rumor is that they had a patent on IDE HDD selectors and that killed the RomTec Trios and the Trios II, as well as the Combox (which seems to have finally sold out on eBay). I’m not sure if they hold any patents that would prevent anyone from legally making any SATA selector products or not.

I was able to find a device called the SATA Switch also known as the SW-SATA2X4.

SATA Switch SW-SATA2X4

Here are some of it’s features:

• Uses a 3½” bay
• Supports SATA II (thus is SATA I compatible)
• Supports up to 4 drives
• Controls the drives by only powering the one selected
• LED to show which drive is selected
• Can be locked with a key to prevent someone changing drives
• Costs only $89.99

I haven’t been able to figure out the original manufacturer of this device, but it’s being sold on a number of sites.

I’ve also come across a guide on how to make your own SATA HDD Switch. The author also sells this homemade device for $29.95 and has another version that supports switching between 2 sets of RAID 0 or RAID 1 drives for $32.95. It doesn’t have LEDs or a button to press, it works with a toggle switch (although you might want a shield for it so you don’t accidentally bump into it).

Troyka Combox Drive Swapper
note: Dell & Compaq owners may need a power cable adapter.

This is the device I currently use. It only allows for one hard drive to be used at a time and has a system protection switch to prevent you from changing it while the computer is running. Since Combox controls power distributions to the drives, it will work with any drive interface (IDE, SCSI, Serial ATA) and any system whether old or new (Pentium and higher or equivalent, according to the old Troyka website). It also works with Primary/Secondary channels and PCI or Raid controller cards.

Selection device is done by a digital touch control similar to the Trios II (basically just buttons similar to remote controls so don’t pop in and out like the Trios), however it is not a wired remote. Like the Trios II the LED stays on when the computer is powered off so you can see what selection you have picked. It takes up a 5 ½ “ bay with the touch selection on the outside, but at least you can place one of the hard drives inside the base of the unit. It takes up a card slot but doesn’t actually plug into the motherboard, basically the card just controls which device gets power, it also has to plug into the power supply connector, and the power supply cable plugs on the top of this. This allows it to control the power any device being used and gives the touch interface its power. It comes with a special hard drive cable that can connect to three hard drives so you only have one cable to deal with.

Unfortunately, this item wasn’t around for very long and there probably weren’t many made. Their website went down within a month. Supposedly Troyka is the same company that Romtec was and was infringing on some patent. These items were on sold on eBay by one user for quite a while, so apparently he had access to their left over stock.

Pros: Only the selected hard drive gets power. Only have to deal with one hard drive cable.

Cons: Hard to find.

Romtec Trios II PX-920T2 Multi Drive Selector
note: Dell & Compaq owners may need a power cable adapter.

I’ll admit I never owned the Trios II model, but will summarize the features of the Trios II over the original Trios. Here are some exact quotes of the device from the now defunct Romtec website:

“TRIOS II controls not only one drive at a time but also controls 2 drives simultaneously. Master + Slave setup enables you to run 2 drives, one drive as Master the other as its slave. You can create your own configuration among the Hard Drives (O/S or Data drives).

Besides running up-to 3 OS independently, it allows you to run 2 drives simultaneously, clone drives, transfer data, and back up systems.”

It comes with a wired remote that plugs into a card that just uses a PCI slot but doesn’t actually use the slot other than just to hold it in place. Apparently it only gives power to the hard drives selected. You can run one drive as master and another as slave, or have one OS and 2 slave drives and switch between the slave drives or use it with three separate systems like the original Trios. Rather useful if you want to have a drive with just data and keep the OS on another drive, although you could also spread a virus to the other drives.

note: There was a Trios II plus model also.

The old Romtech website states:

"TRIOS II Plus guarantees you 100% compatibility with all systems old and new. It is an upgraded version to our already reliable and dynamic TRIOS II which works with all systems up to Pentium III or equivalent.

TRIOS II plus is not only for hard drives, but any IDE drives. Hard Drives (O/S or Data drives), CD-ROM & Writer, 3D Imation Drives, DVD player & writer, ZIP Drives, etc. Flexible and compatible, you’re in good company with TRIOS II plus. TRIOS II plus controls not only one drive at a time but also controls 2 drives simultaneously. Master + Slave setup enables you to run 2 drives, one drive as Master the other as its slave.

Since you have up-to 3 C: Drives in your single PC, you probably need to transfer or share files among those drives. No problem. With TRIOS II plus, you can directly transfer files between your C: drives. Now transferring data is as easy as 1-2-3
* Caution: The Drive should be same file format system in order to transfer data among them.

Clone drives to keep your system backed up and secure. Now you don’t have to disconnect a drive or deal with removable racks after cloning in order to keep one in a safe place. TRIOS II plus allows you to clone and hide without all the hassles by using a 3rd party cloning utility such as Symantec Ghost."

Whether or not the regular Trios II allows you to use other IDE devices, I’m not sure, but it seems reasonable. The LED on the remote stays on even when computer is shutdown, but that’s so you can swap drives and see which one is selected.

Pros: Wired Remote is touch based. It doesn’t take up any bays. You can run two drives at the same time. Only selected hard drive(s) receive power.

Cons: Requires 4 IDE cables coming off the PCI card.

Romtec Trios RX910T6

Select between three IDE hard drives with push-in button interface. Before you turn on the computer, you press the button of the hard drive you wish to use. This "pops" out the button for the other hard drive previously selected. If you have kids its possible they could press all three buttons and get them stuck down, although I never tested that. I did test it with two buttons depressed and it allowed you to do that, but pressing the third button popped them both out. However, only one HDD can be selected. The Trios has a built in system protection switch that won’t let you switch drives while the computer is running. There is a green LED to the left of the button that is depressed, so that you can tell from a distance what drive is being used. Only put one hard drive per IDE cable coming off the Trios.

The old Romtec website states:

“TRIOS is compatible with any IDE hard drive and all system processors above Pentium I. There is no limit to capacity, size, speed or manufacturer as long as the BIOS supports the drives. TRIOS supports the following speeds: (ATA/33, ATA/66, ATA/100).”

Pros: Easy selection between three hard drives.

Cons: Each hard drive gets power and very warm. You have to have an IDE cable for each drive; thus, you end up with four IDE cables hooked into the Trios (even if you use rounded IDE cables, it still takes up a lot of space and is a mess). It takes up a 5 ½ " bay.
