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.

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.

I get all and that, but is the Seagate SSHD the only one that is worth it, or is there something better in the horizon (besides a SSD, of course) ?

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.

Yes, quantum hardisk is coming soon.

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

Errrr...can someone help me, my portable WD shows RAW not NTFS or FAT32..tried to format but windows cannot format the portable. how to solve..please

Quantum harddisk? What are you speaking of?

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.

WD Element, later tonight I'll put a screenshot..

Just install any low level format software and low level format your drive:-

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.

Greetings, I have several questions regarding hard disk. I just bought a 6TB WD Red 3.5" but i still can't use it on my PC since i still need a new graphic card to make my PC work again. So i'm wondering if i can use it as an external hard disk in the mean time and use it as an internal hard disk once my PC is working again..So my question is..is it even possible to make it as external hard disk? If yes how? and if i want to make it as an internal again will i have to format the data or something..? Any help would be appreciated, thanks in advanced!

I hope your intention is to NOT to use the 6TB hardisk bootdrive in your PC. As storage data, it should be ok.

Just buy and external USB 3 or USB 2 case and install the hardisk inside it. Format and use it normally.

When your PC is up and running again, take the disc out of the external casing and install it in the PC on an available SATA port. You should not need to re-format the drive.

Well i already intended to use the hard disk as a storage because afaik WD Red is not for performance and i tend to gaming often so it's not an ideal thing to make it as a system hard disk. Thanks for the advises i'll try to find an external HDD enclosure. May i ask more question? After some browsing for the enclosure i found the keyword "up to 4TB" this makes me wonder..is there a limitation on the volume or something if i convert it into an external HDD? Thanks!

wd blue vs green 1tb, which is better?

As primary drive, WD Blue (good all purpose hdd, sometimes comparable to wd black, 7200RPM)
As secondary or long term storage, WD Green (low power consumption, low noise, low heat and got some special technology in it for long-term reliability)
