True Toughbook CF-19 twin engines with 2x128GB Samsung msata Raid 1 controller

This "looks" like the same adapter. Don't know if that other seller has done any modifications.

This is interesting..It uses 4 SD cards...

Understanding RAID arrays
Redundant Arrays of Independent Disks (RAID) technology allows a computer to use two or more hard disks at the same time. RAID treats multiple drives as one contiguous drive, either through hardware or software settings. If multiple disks are set up to work together in this fashion, they are referred to as a RAID array .
Users should consider the advantages and the restrictions before trying to setup a RAID array. If the PC was not manufactured and configured with RAID, it may be necessary to purchase a separate operating system or license, and reformat the drives before configuring the arrays. Keep in mind that the new operating system you purchase must be supported by the hardware and component manufactures to ensure that model specific firmware and drivers are available. Also, depending on the RAID array, it may be necessary to use a separate data backup system.
What benefits does a RAID array offer?
The computer sees multiple disks in a RAID array as one contiguous hard drive, with the goal of providing better data reliability or faster performance.
Some RAID arrays provide backup redundancy for data by organizing data in files across multiple physical hard disks. With this configuration, if one physical disk fails, some of the data can be reconstructed. Other RAID array configurations provide more speed and data efficiency in storing data, but do not offer data redundancy.
NOTE:A RAID array configured for file redundancy is not a substitute for proper file backups. Data can become corrupted or overwritten even if the physical hard disk itself is undamaged.

What are the different types of RAID arrays?
RAID technology allows improvements in data redundancy and speed. For sophisticated or complex situation, there are six RAID configurations. However this document only addresses three of the most common configurations.

RAID 1 - Mirroring. In mirroring, the same data is copied to more than one physical disk. This mirrored array provides some file redundancy, however this can reduce the amount of space that is actually usable on the hard drives. With mirroring, the data is probably recoverable even if one disk fails. Writing the data to multiple locations on the hard disks can also slow overall system performance.
RAID 1 - Error correction. It may be considered by some people as a separate configuration, however other people suggest that error correction, also called fault tolerance, is actually a benefit of Mirroring. In either case, because the same data is stored in two or more places on multiple drives, it can be checked for problems and fixed.
RAID 0 - Striping. In striping, data is split apart and stored on more than one physical disk. This striped array improves read / write performance and gives you additional storage space, but offers no file redundancy. Because there is no error checking, if one disk fails, all information on that drive is lost and is unrecoverable.

The only problem I have with the SD card version ones is I can only get linux to load on it. I have a single and double. Didn't find a 4 card version cheaper than 50 bucks at the time so I didn't order one.

The triple Msata set up in the MSI GS70 can go over 900 mbps.

I figured you already tried these Paul. Will the dual or triple msata versions drop into a Toughbook without any issues?

I was going to post about this today as it popped up in my eBay automated search email.

Claes/Jacob, have a look!

Interesting. Those Samsungs retail for around a hundred bucks each and the adapter goes for fifty.

I have still been messing with these style adapters for IDE use, not SATA. I looked for something like this about a year ago but none were available. (Dual SATA) I will probably be ordering one soon to test out though.

All the ones I have tested so far have worked well.

IDE to SD card
IDE to CF adapter
IDE to CF adapter with compact flash adapter to use a SD card (single SD card, Dual Micro SD cards) that make a Compact flash adapter that also uses quad Micro SD cards but haven't tried that one.
IDE to Dual Compact Flash Adapter.

I tried the SD card route with Class 10 cards because of the high price for Compact flash, only issue I see is windows not recognizing SD card as a valid media to install too. I though the Compact flash adapter might trick it but it didn't. I didn't run and linux speed test yet but seat of the pants speed feels fine.

The last adapter I got was IDE to Single Msata. It turns out the Msata card I had was for a dell mini and the pin out are different. I got a x25 Msata to use for testing, but haven't used it yet in the M34 yet.


Using something like this in raid is about the only way to get around the SATA 2 speed limits (both drives speeds are added together) and is something worth looking into.
