You have a SATA II connection for your hard drive - 3.0 Gbps Serial ATA. Buying a SSD rated at 6.0 Gbps Serial ATA isn't going to do you any good (such as the Crucial m4 series).
sorry but no and no.
Momentus is a mixed bug - not an ssd actually - and have mixed user responce
Crucial is a good thing, just bit outdated and they mess up with firmware updates. Also you'll need trim enabler for crucial
for all-purpose install-and-forget I'd say something like OWC6G serie or latest of Vertex3 (not 4)
for tinkering with trim enabler - Samsung 830-840
Is that a problem if I install the crucial without the trim enabled ? OWC I wouldn't like to buy since I am from Portugal and I don't have it available here.
I was thinking between the these options:
Which one would be better to choose?
Thanks in advance
samsung costs way too much.
Afaik both clintonfrombirmingham and me are using Crucial M4 and its a good drive, more than enough for sata II
Using drive without a trim is not a problem, just over time (it'll depend on usage pattern) speed will degrade a bit. With mild usage M4 on sata II probably will not lose lot of speed.
process will take months for heavy enough usage and years for light usage. And trim enabling is an easy trick.
All SATA III are backwards compatible with SATA II, you just get reduced speeds.
I have the momentus 750 gb in mine currently and it works fine, great if you want a compromise between speed and space and cost.
as for pure SSDs you can go for the samsung 840 pro but it's pointless to go for such a premium drive since you only have SATA II, might as well look for a lesser 256 gb and pay a lot less, like the OCZ agility 4, for instance.
but if you do decide to go with the seagate the 750gb version is miles ahead of the 500gb
