Momentus XT vs. Itel 40GB SSD

I've been thinking about this for a while now but need some opinions/help. I'm looking at getting the Momentus XT so I can have my OS and all my games on my boot drive so it would increase the read speeds of both my OS and games. However, the 40gb Intel SSD is an actual SSD, but only 40GB. This would get full very quickly with my games. Or should I bite the bullet and get the 80GB Intel?

Edit: Also looked at the OCZ Agility 2 60GB, looks good and will give me some playing room for extra games. Would this be the best option? Or is one if the previous?

I assume this is for your Laptop? In that case I like the intel options. They have the best speed per watt, so to speak. They sip the power and provide great IOPS for things such as games and the OS. Buy the largest you can afford.

The momentus xt is very impressive, for what it is. However it is still a spinning disk with 4GB of 'buffer'.

If you're worried about space buy an external drive for pennies/gb. It'll give you a nice place for total system backups as well.

Desktop, so I'm not so concerned about power, even though I would like to now the best option for my laptop for when I can upgrade that. But my windows installation takes up 44.2GB, so I would like a good extra amount of room for more games. I like the 90GB OCZ Agility (http://www.newegg.com/Product/Product.aspx?Item=N82E16820227604), cause it has another 10GB compared to the Intel for the same price.

Also I have an extra HDD, for my documents and everything else.

What do the gen3 drives have. I can only support SATA 3, also I think I might wait a little longer because supposedly prices are supposed to drop. If so I think I might stay with the OCZ Agility 2 and just get a 120GB if its cheap enough.

I thank you for stopping me from making a terrible decision. That just leaves the question on whether or not to go with the OCZ Agility 2. I've heard good things about the Sandforce controller. So should I see if there is going to be another series of OCZ SSDs with the Sandforce, or wait and see if something better pops-up when the new ones come out?

No, only an X1 slot. I shall look for something like this. Thank you. But my question still stands. Is the Sandforce controller as good as I've heard, and should I wait and see if they have a newer series of OCZ Agility 2? Or should I just go with the Intel drives when they come out?

EDIT: I can't find one.

When i did look at some other site reviews about the Momentus because i am thinking of buying one,
all the people are really happy with it, (sorry the reviews are in dutch language, but they are on tweakers.net
i just went to here to see what other people think about it)
It amazes me that all the people here say go for the bigger ssd, if you want some extra speed and lots of more space
i really think that the momentus is a very good option.
Written data is always put on the platters, but what it does is that it loads the most used data in the 4 gig partition, boosting that part with speed, and because of that windows starts up very fast, since the most used files of windows are actually not that much big there is enough space for other data on that 4 gig partion, boosting the startups from those programs. Assuming you don't play 10 differend games on a day, after a short while the games you play the most will be written in the faster part of the harddisk speeding up that part.

Namaste,
Aernout.
