I have an unusual take on computers - I just want mine to work for me, not get the extra five percent of performance. So I think that this article, especially the first graph on the linked page, says it all: http://www.tomshardware.com/reviews/sata-6gbps-performa... .
Any SSD will be a massive improvement over an HDD. If you benchmark, or run high-performance stuff, ask someone else for an opinion.
There are a lot of articles about tweaking SSDs, starting with this one: heck, I lost my link. Sorry. The topic of whether to have a pagefile on the SSD or not have a pagefile is a religious one; both ways are functional options. The most basic and important thing is to set your disk controller mode to AHCI (or RAID if you will be using it) before installing the OS to the SSD. Do a fresh install.
That is very helpful thank you. So basically you're saying that buying one SSD over the other doesn't really matter which I kind of assumed I just didn't want to make a mistake. Thank you for the links also. Any suggestion on which of the 3 is safe to get? I don't know if reliability is an issue with SSD's like I have heard before.
Do frequent system backups and reliability is a non-issue. I personally have a pagefile on my SSD and my temp storage, too. It puts more writes on the drive, but the drive is there to serve me, so let it work. And degrade. I can always do an OS restore to a new one.
BTW, these graphs have convinced me that the Intel x25-M is not a sweet drive: http://www.tomshardware.com/reviews/ssd-performance-twe... . I have no opinion between the others, but faced with that choice myself I would buy the Vertex as the better-known line. Anyone out there really know?
If you have the budget, you should be able to land a nice 256 GB SSD for around $160 if you catch one on sale. I'm sure you've already assessed your needs and determined that you can fit comfortably into a 128 GB SSD. Just one thing to keep in mind... as an SSD reaches its capacity, it can slow down AND having little free space wears out the drive quicker. In other words... if you have a 128 GB SSD and plan one keeping it filled to 120 GB, you are shortening the life of the drive by contributing to excessive writes to the same area of the drive. I have owned a 64, 128 and currently a 256 GB SSD and each step along the way I felt like I outgrew my drive. Between Windows service packs, Adobe updates (bah!) and games that are getting larger and larger (some games I have exceed 20 GB), I felt like 256 GB was the sweet spot for SSDs... and yes, I still have a mechanical drive for other stuff.
