Ostan kaksi tuommoista ja pistän ne RAID-0:aan. Ovat jo ihan hyvissä hinnoissa.

Flash-muistilla toteutettu kiintolevy. Paljon nopeampi kuin normaali kiintolevy. Ei sisällä liikkuvia osia. RAID0:lla pystyy vielä teoreettisesti kaksinkertaistamaan luku/kirjoitusnopeuden, kun käytössä on kaksi levyä. Kolmella levyllä taas teoreettinen nopeus kasvaisi kolminkertaiseksi jne...

tässä on hauska video, kun kaveri kasasi kunnon koneen 24 SSD-levystä. :D

Intel X25-M G2 näyttäisi olevan markkinoiden parasta SSD-tekniikkaa.


A Personal Anecdote on SSDs
I’m writing this page of the article on the 15-inch MacBook Pro I reviewed a couple of months ago. I’ve kept the machine stock but I’ve used it quite a bit since that review thanks to its awesome battery life. Of course, by “stock” I mean that I have yet to install an SSD.

Using the notebook is honestly disappointing. I always think something is wrong with the machine when I go to fire up Adium, Safari, Mail and Pages all at the same time to get to work. The applications take what feels like an eternity to start. While they are all launching the individual apps are generally unresponsive, even if they’ve loaded completely and I’m waiting on others. It’s just an overall miserable experience by comparison.

It’s shocking to think that until last year, this is how all of my computer usage transpired. Everything took ages to launch and become useful, particularly the first time you boot up your PC. It was that more than anything else that drove me to put my PCs to sleep rather than shut them down. It was also the pain of starting applications from scratch and OS X’s ability to get in/out of sleep quickly that made me happier using OS X than XP and later Vista.

It’s particularly interesting when you think of the ramifications of this. It’s the poor random read/write performance of the hard disk that makes some aspects of PC usage so painful. It’s the multi-minute boot times that make users more frustrated with their PCs. While the hard disk helped the PC succeed, it’s the very device that’s killing the PC in today’s instant-on, consumer electronics driven world. I challenge OEMs to stop viewing SSDs as a luxury item and to bite the bullet. Absorb the cost, work with Intel and Indilinx vendors to lower prices, offer bundles, do whatever it takes but get these drives into your systems.

I don’t know how else to say this: it’s an order of magnitude faster than a hard drive. It’s the difference between a hang glider and the space shuttle; both will fly, it’s just that one takes you to space. And I don’t care that you can buy a super fast or high flying hang glider either.

OCZ Vertex myös hyvä valinta. taidankin ostaa vain yhden levyn näin alkuun.

Vähän mietityttää noi laitteet. Ovatkohan yhtä hyviä kuin tavalliset kovalevyt?

"Since RAID cards aren't going to support TRIM commands for a while, I'd stick with a large, single SSD."

Raid ei ilmeisesti tue vielä tuota TRIM-toimintoa, joten siinäkin mielessä kannattaa käyttää ihan normaalisti tuota levyä ilman RAIDia.


Ainakin noiden tyyppien mielestä ovat ihan toiselta planeetalta verrattuna hitaisiin mekaanisiin levyihin. Itse en ole vielä käyttänyt tuollaista tietokonetta.

Esim. Intelin 80GB levy on alle 190€. Ei enää kovin kalliitakaan. 


Massamuistinahan voi samassa koneessa käyttää perinteistä levyä, jos on esim. paljon videotallenteita. Käyttöjärjestelmä ja sovellukset sitten asentaa nopeaan levyyn.
