| Re: SDHC RAID device from PhotoFast Interesting idea, but I think solid state drives are an idea whose time still has not come. In addition to whatever the cost of this device is, six 16 gB SDHC cards will cost around $350 to $400 or more, for 96gB of storage. Not a very good $/gB ratio. Also, flash memory has a relatively limited lifetime in terms of the number of write/erase cycles it can handle, relative to what hdd's can handle. That is probably particularly true for the cards that are likely to be used with a device like this (cards that are not targeted for ssd applications). I wonder how reliable they would be after two or three years worth of use in a system drive application. Regards, -- Al

| Re: SDHC RAID device from PhotoFast It is a neat concept and if the writing algorithm was designed to distribute the writing such that every memory cell was written to once before writing to a given cell again to distribute the usage, the life span could be quite long. That's what they do in the SSD HD's. Thing is, RAID 0 has no redundancy, so is one dies, you're screwed.

| Re: SDHC RAID device from PhotoFast Also the max is 6 x 32gb for a total of 192gb, which would be perfect for a mobile application, a car, a tank, a boat, anything that can be bounced around quite a bit. I can't wait until SSD matures and becomes affordable. |
