this for me has to many variable's what i mean is the sdhc cards that and the cost of the said device. jmo very interesting to say the least

Any more suggestions?

not really just depends on the cost of this, if cheap then go for it.

I tried one of these at a computer show in HK almost 2 years ago, wasn't very fast, (only ok for small file transfers) you're better off with a Velociraptor if you want speed and capacity.
However it seems they have updated their chipset, but I doubt that would bring a night and day difference.

I see. Well i own one of those Memory Stick to 2 microSDHC adapter for my PSP and boy they are fast. "coughcough" Loads way faster than the UMD drive :)

I see speed AND reliability being the main concern.
SHDC NAND is well....cheap nand. It doesnt have the write performance of higher grade nand found in SSDs. So its write speed is going to suck in comparison even within a 8x raid array. Sure its sequential speed might come close...but I bet its 4k numbers will stink.

And SD cards are cheap because they use cheaper nand...thus they dont have the realistic expectation of surviving the same number of writes vs a SSD's MLC NAND. This has gotten better with time, but the SD/SDHC mfger's dont expect you to USE the external storage in a continuous manner.

I have a dual CF to sata port raid 1 gadget here and while I'd use it for a freeNAS C drive where writes are low to rare...I wouldn't trust it as my OS drive in a 2ndary rig!
