what do u mean by 'CACHE' in a hdd or ssd what does it actually do , i have a 1th wd hdd 5400 rpm i am not satisfied with it i am planning to buy an ssd is it actually good or its just over rated is it worth buying if yes which one ??

1) people say you should cache your ssd with your hdd what does that mean ?

2) and ssds are expensive i can only afford a 120 gb 1 so how do i store my remaining programs in the c drive once it gets full ??

That cache stuff is useless for the average user. Don't worry about it. Essentially it means you will be using your ssd to store frequently used data, so it makes it feel like your hdd is actually as fast as an SSD, while still getting all the space in your hdd. However, this doesn't work as well as it sounds... cache was popular back when SSDs were like 32gb in size and costed hundreds of dollars.

SSDS are NOT overated. They will greatly improve your systems performance. Its like night and day.

SSD's are well worth the cost. Youtube has some nice videos on SSD's vs HDD's in identical systems. My boot time is under 15 seconds for my desktop & laptop (both have SSD's).

Here is a similar thread with a 5400 RPM drive vs an ssd: http://www.tomshardware.com/answers/id-1839324/128-ssd-...

@oczdude8 i understood somewhat what u meant now imagine after i get a 120 gb ssd i install windows 8 on it and get all my other applications on it bt 120 gb is less space once its full where do i install programs that require to be stored in the c drive ? And the cache thing is some mode that i have to enable to make my hdd feel like an ssd or it happens automatically whats the deal ?

You want to install your OS and other high disk IO applications on the SSD drive. Then install your other applications on a secondary hard drive. Basically, change the drive letter the application is installed on from C:\*** to the drive letter your platter drive (non-SSD) lives on. You can also change your default documents profile directory to your platter drive too.

You want to make sure you leave about 20-30% free on the SSD. Otherwise there isn't enough space for cleanup activities and other maintenance activities. If that happens, your speed will slow down quite a bit.

Caching happens automatically for hybrid drives. I'd avoid them though because their performance is not very good considering their SSD storage is usually rather small. Here is another Tom's post about the same question: http://www.tomshardware.com/forum/284773-32-hybrid

I remember one saying windows and frequently used programs on the ssd, basically once you install windows on the ssd that's it you don't have to worry anything else. Any programs that require ssd-like speed goes to the ssd, programs like games and stuff, while the rest(videos and pic and stuff) goes to the hdd. You need to stop worrying about cache, all ssd does is inncrease performance by reducing access time, treat both drive separately. Most people rarely fill up their ssd(using a maximum of 50% of the ssd space to max performance, and everything else on the hdd) Do not let your ssd be full, it will severely hinder performance which is why most people pair their ssd with an hdd. Your setup is normal just treat both of them as separate drive, and like i said, any program where speed is crucial, install it to the ssd. Everything else like winrar, winzip and the like you install in the hdd.

Yes install windows 8 on the ssd, and by doing this the hdd's performance will be the same but the experience of using an ssd + hdd for windows will be better, faster because it's the ssd who is doing all the heavy work, and since windows don't have to write tons of files/data to an hdd(if you install windows to the hdd which is not wise) the workload on the hdd will be lighter(free to do other stuff such as watching a movie or viewing photos) and of course faster, and generally you will feel the system becomes faster, more responsive. Generally avoid any cheap ssd, 128gb is the absolute bare minimum (for me anyway), 256gb is the sweet spot for performance and storage capacity , anything north of 256gb is generally waste of money. The best for me and currently using would be the samsung 840pro. :)  but if budget gets in the way get a 120/128gb ssd instead, it WILL still trumph over using an hdd alone. Another tip for you; 1)if the game your playing has huge map with insane 64 players duking it out with each other such as battlefield 3/4; 2)any frequently played games be it internet or campaign 3)games with frequently changing maps/level or it loads something frequently 4)any noticeable loading time(irritating one) (excluding the beginning of the game) during gaming - install it to the ssd. With games nowadays reaching upwards of 20-30gb easily I would install one or two games on the ssd, finish them and un-installing but keeping the save files, that way I can replay them if I choose to. and last but not least, with ssd reaching a wall with sata 6gbs, and the newer interface (sata-express, M.2) still a long way from becoming a standard, any good quality ssd will feel the same over the aging sata 6gbs, and of course an hdd. So any good ssd you own or choose to buy will be just right.(provided it's a good one) Just walkthrough Tom's Hardware reviews(they are awesome!!!) and find one just right for you. Good Luck :)

Your welcome :)  it will be just fine. The performance between the two is quite close and you won't be able to tell the difference between the two. (Newer)Samsung is excellently reliable. They are korean made which translate to better overall quality and will last longer and will retain their performance for a longer periods of time.

If budget permits, then yes you should opt for the pro model. :)
