Oh.Crap. No wonder I've been seeing threads about replacement boards for WD HDDs.

So far, my old 1TB WD from 2010 still ain't dead yet...

Also, what is this I hear about SSD/HDD hybrids?

Errr... if you make your question a bit more specific, I'd know what to answer. unsure.gif

Basically its normal HDD with a big cache built into it to boost the HDD performance. For Seagate SSHD, this is a 8GB NAND. Price sits between SSD and HDD.

You can read more about it here - http://www.storagereview.com/seagate_desktop_sshd_review

Hardisk manufacturer should just put 8GB NAND in all the hardisk.

8GB nand so cheap now.

Yes they should but that would also mean that you need to put in different type HDD controller to manage the larger NAND cache. Currently LSI and Marvell are the only ones I know in 2013 making these controllers. These SSHDs haven't gotten its chance to shine yet as consumers have yet to know the performance benefits.

SSD is a technology currently available.

There will always be new technology in the future. And as with all new technology, it will cost an arm and a leg when it's first released, but the real question is - What is the real cost for you waiting for it to arrive?

Just my 2 cents - if you have the need, just go ahead, take your pick and buy it. Enjoy the tech while it last coz there's always going to be something better to replace it in the future.

Well, if 8GB is the standard, just design once and use many times. Haha

Well unfortunately not such an easy thing to do, LSI (that makes the popular flash Sandforce controllers) was bought over by Seagate last year. If they play their cards right, they could gain the lead in the flash storage market.

What is the model of your WD ext HDD? Also a screenshot of the error would help to have a better understanding of what's happening.

probably Seagate will wait until they acquired NAND supplier.

They don't need to. Look at Plextor, they don't own any NAND units but are happily churning out SSDs.
