What computer?
There is an eSATA cable extender for Mac Pros which is a little tricky to install but works exactly as advertised. Read/Write speeds are the same as internal drives. The only downside is that you have to reboot if you have unmounted the drive and wish to remount.

An eSata drive is essentially just another internal drive [albeit outside the main case. So you should simply regard them as internals. So you have to remember to turn them on before booting up.
I have an eSata PCI card and 4 big eSata drives all doing nada as the wretched thing refuses to work!!!!!
Which card, what is your bus speed and computer model, and are they RAID?
Mac Pro March 2008 8 core 10.5.5, HighPoint RocketRAID 2314 and in theory yes RAID is possible and if the HDs appear, Disk Utility can RAID things or the card itself can.
Of course it should drive 4 units it’s a 4x eSata PCI card. It seemed to work with my Icybox 4 HDs in one enclosure when I first tried with a couple of HDs. It then refused to work with all 4 HDS in place, plus the enclosure was sooooooo noisy it was dispensed with and 4 individual [and silent]enclosures were then used, but are completely invisible to card.
But then as my MP/OSX is so %*^%*^%ing unreliable with everything else, it’s may well be that at fault. About to do a 4th [or 5th?] reinstall!!
The card and drives may have to be same manufacturer to be RAID.
Sorry, but that’s complete nonsense. That’s not how RAID works. Adaptec and Highpoint, do not even make HDs.
But it’s the fact the drives are not even recognized in first place, that is the main issue with my set up, so RAIDing isn’t even a possibility.
Some more info in regard to your initial post. LaCie just repackage other peoples drives in pretty boxes – same goes for the Monitors. And you can use any SATA HD in an enclosure that has an eSATA port to use as an eSATA drive.
LaCie says their high capacity drives can’t be RAID without the laCie eSATA card, sorry, you’re wrong.
RAID works however they want it to work, and don’t tell me it’s nonsense. You’re trying to do something you can’t do , and keep a civil tongue in your head , young man. Turn that music down and get off my lawn.
I would be happy to get off your lawn after I drive my Hummer through your front door.
I’ve always wanted someone to give me a hummer.
As I said above RAID controllers are normally made by companies who do not even make HDs. LaCie, to maximise profits have chipped some of their eSata drive to only work with their eSata card which is probably a rebadged highpoint/adaptec/… card anyway. This is a separate issue to RAIDing.
So I am not trying to do something I cannot do as the card I have is for any non proprietry eSATA drive and I am not using LaCie Drives. I’ve used RAID for 10+ years, so not exactly new territory for me. Just as computer kit not working as descibed is nothing new.
