SSHD-why so expensive?

manic111 · 21 Jan 2008 at 19:03

Why are solid state HDDs so expensive? Surely they are effectively SD cards which fit into a SATA port. You can get a 16GB SD card for about £60, whereas an SSHD of that capacity will cost upwards of £200!

As far as I know the speed of a proper SSD would blow away an SD card, also there maybe an issue of the reliability after a large number of read/writes.

Yep, it's a different technology that is used to give it the same lifespan as an normal disc.

not sure about "blow away" a normal flash drive

just got a 8gb Buffallo usb stick - and it manages 31MB/second average across the drive read speed

The fastest SSHD does 120MB/Sec Read and 100MB/Sec Write.

Which is incredibly bad in regards to normal harddrives, SSDs over normal harddrive performance in regards to transfer speeds + the lovely latency. And then it uses technology to keep it incredibly reliable. All that in a new product means extreme prices at first, but i'm willing to bet that in 7-9 months we'll see at least 10 products on that page, with lower prices, and people will start taking a few chances then. There are also a lot of companies in the business now, they will fight and lower prices that way.

Plus they scale virtually perfectly with raid setups and a good controller.

It's new technology, which will always cost a fortune. In the price of the product they have to pay for the years of research before they could actually put it into production. Also with it being a new product they can charge more because of the demand. SD cards used to cost a fortune when they first came out, I still have a card that cost £50/gb.
