SSD or Micro sdHC cards ??

[jimbo45]

Hi all
given the fact that some micro SDHC cards are already 32 GB capacity and it won't be too long before 64 and even 128GB one's are available -- is SSD technology --although still in its infancy already on its way out.

Seems to me that if Micro SDHC cards can reach this sort of capacity (64 / 128 GB) capacity and the electronics is fast enough --these cards will last infinitely longer than an SSD drive and won't have any of the attendant properties of these drives either.

(Having just spent nearly 400 USD on a 256 GB SSD I could have been jumping the gun).

While USB2 or even USB3 is still comparatively slow there is no reason why a micro SDHC card with the proper interface should not be faster than an SSD on an enhanced IDE / SATA bus.

It isn't just the memory capacity that matters. You are forgetting one very key part of an SSD....the controller. A flash memory card still needs to run over some type of connection that's inherently slower, even if it was an eSATA card-reader, or something of the sort. An SSD uses a built-in controller (Sandforce, ie) to provide direct access (and maintenance functions) between the SATA interface and the memory.

Why do you think these cards will last infinitely longer than an SSD? I believe they are subject to the same limitations as SSDs.

Here is an article I found that talks about the advantages/disadvantages of using SDHC vs SSD vs HDD: SDHC Cards vs Hard Drive vs SSD

I had a netbook with a 64G SSD and used a 16G SDHC card as my data storage which worked well for me but as the article above states, write performance is slower. Once the data is saved to the card it can be read quickly.

1. They are very slow and will never match SSD speeds, and I doubt will ever even match HDD speeds
