SSD HDDs? - bit-tech.net Forums

I'm looking to buy a SSD HDD for my laptop, like this one from Scan.

Scan don't have them in though and no idea when they're coming in.
Anyone seen them in stock anywhere else?

Oh my god at the price of that thing... I THINK I'm gonna wait for another while for those to really hit the markets.

airchie · 30th Nov 2007, 21:25

Yep, they aint cheap but I want it.

Plus I just sold my main PC to fund it...

Holy crap, that's the coolest thing I've ever seen. 64Gb of flash? Yes please

I don't use the site myself, but overclockers always seem to have stuff that's unavailable elsewhere. Try there?

Yay for limited writes and minimal performance change!

lamboman · 1st Dec 2007, 17:51

^^ My thoughts exactly.

SSDs are gonna be great when they get going, with silence, reduced power usage, and higher speed, but at the minute they suck.

Fishlock · 1st Dec 2007, 18:18

Oh my.... £568 for 64GB of SDD.

As said above, they will be superb when prices drop for obvious reasons, but not many people can afford that considering the constant demand for more disk space.

not trying to go off topic but approx how many reads/writes can you get off of flash memory?
Its seams a bit off to buy something that wont last very long with heavy use.

edit: after discovering that I needed to search for "flash endurance" I was able to find that the minimum number of write cycles seams to be at 10,000. which according to this site:
http://www.kingston.com/nlroot/flash/flashendurance.asp
turns out to be many years of use.

As I understand it, the new gen SSD HDDs spread the use of the flash out to use all blocks an even number of times, so the life expectancy is much greater now.
I think the newer gen memory is also more resilient and allows more writes than the older stuff.

The question is though, has anyone seen the new Samsung ones in stock anywhere???

True. It isn't on the market yet, though.

That £200 Asus Eee lapdog has a SSHD. Only 4Gb though. But it suggests they'll have a decent life.

Quote:

The Eee has a 4GB flash disk instead of a conventional hard disk, and at 2.5GB the OS consumes over half that capacity. That means you'll never be able to install any recreational media - videos for the plane, for instance. But, it's more than enough space for hundreds of office documents, and we failed to find a USB flash drive that wouldn't work one of the Eee.

The majority only guarantee for block 0, not the rest.

Also, flash doesn’t allow random access erasing. So the whole block has to be rewritten to change one byte.

airchie · 1st Dec 2007, 21:26

Cool, a few years use will do me tbh.

That's IF, I can find someone able to sell me one??

But you can define the block size when you format, can't you? So couldn't you bypass that problem by making it really small?
Or would that make performance suffer?

airchie · 2nd Dec 2007, 00:43

I don't think it would make it suffer too much.

Actually the good ones now last "as long as hard drives" because they cycle where they write to and the speed of some (Super Talent comes to mind) are in excess of that of hard drives - 80-100MB/s. But they are even more expensive. The cheaper ones are truly **** though.

NTFS on normal hard drives means you can only erase or write blocks at a time too - 4k.

They are *ideal* for notebooks (super low power, jog-proof, instant on), but too expensive atm. Just sell your notebook and buy a Sony Viao with one in. Best-notebook-ever. TR reviewed it a while back.

airchie · 2nd Dec 2007, 12:57

Hehe, I read TR's best of 2k7 article and got the feeling they loved the Sony...

I just want to make this laptop nice and fast.
Its fast already but severely let down by the HDD performance. :/

Dev25 · 2nd Dec 2007, 14:20

I think i'll wait for a couple of years (More like 6/7+) to at least think of gettin one

Then unless you shell out for one of the super-fast 100MB/s ones you won't see any performance difference.
