5400 rpm is pretty slow to start with, especially for a performance notebook like Illegear
And it will only get slower as it ages and gets filled up.
I would suggest going for a hybrid HDD with mSATA at least for faster performance, and perhaps upgrade to an SSD when budget permits later on, I'm sure Prince J wouldn't mind helping to upgrade 

My personal experience with big @ss HDD is that we tend not to think so much when we save stuffs, in the end we get ALOT of files that can be hard to manage (not mentioning slowing down the computer as well since there's more files to read and find). With a smaller sized (and of course way faster) SSD, you will learn how to organize your files wisely, keeping the notebook top-notch, always 
Just my 2 cents

A Razer Blade will rape my wallet yo   

actually, my lappy only consists of my cloud storage files, an OS, some tools, one game (maplestory lol) and several 1080p animes. sometimes, i noticed some bottlenecked loading performance, as im using a 160GB, and only left 40GB free. time to get a 7200rpm hdd.

and yeah, big @ss HDD is pretty hard to manage when it comes to management. i could recommend to get at least 1TB is enough. dont need 2TB or so much.

as always, razer is just like alienware, like to rape gamers' wallets.  

Razer is bigger raper since it doesn't have good warranty support as back up 

Aiya, not everyone (i.e. me) has good internet assess yo, especially in Malaysia
Are you sure its not 1080p of prawns?

256GB SSD is still the optimum I would say, but even so, with my large phD and photography projects, I still have around 40GB left also No games 
Still, I have 3 1TB externals for backup and storage

For the HDD, as long as its 7200rpm it should be fine, regardless of the size. 5400rpm might be a bit too slow already, especially after some time~

hopefully things will get better if razer officially release in MY. though i doubt myself will grab it. even the new m14x-r3 i doubt myself to get it. the price is insanely high for those 2 beast. but design wise, those 2 really a champion in their own league.

But if i was given a choice between m14x and blade 14", blade 14" will be my choice, i like the plain but classy design, plus the thinnest of the blade. (by assuming the blade's ventilation is great)

lol, im not the ecchi type. so i dont collect prawns, i only collect animes (including ecchi animes). but i will watch ecchi types by looking away at unwanted scene.
i only have one 320GB external storage, inclusive of 720p and 1080p animes (around 30 including seasons) only. I will be getting one 2TB with higher RPM and cache when the external one is used up. only left around 130GB on my external one. my main usage on getting external HDD is just to store animes only.

Bold confession   
Words of advice, try to get 2x 1TB HDD or 4x 500GB HDD if possible to reduce the chances of losing data when the HDD gets damaged or stolen. And of course, never keep all HDD in one place. My friend lost almost all her 3 years of hard work when she got robbed of her notebook and HDDs. Luckily she listened to me and store one more at home

Well, if you get an illegear, you still have a secondary slot for larger HDDs, a big plus 

exactly as planned.
i cant bring desktop ones with me when im going for work.

well, if i got one, i will throw in a 750GB 7200RPM for sure. oh yes, and a 80GB SSD for OS booting.

That's what I have in my RE-15 now with SSD for booting and some CAD software, another HDD for other mini programme files And hey now it's seems that RE series can fit in one more mSata SSD so perhaps when time comes can add in one more.

However, still need to double confirm with ILLEGEAR whether my RE can take in the mSata or not

Hi Salamurhaaja,

The old RE doesn't have msata connector but it already has 2 sata connector slot.

5400rpm helps to save battery life that's why we still offer them. Yes I admitted 5400rpm is very slow but it won't be a problem if pairing with a ssd. If you want less heat, noise and greater battery life go for 5400rpm.

Ok so pairing means put the OS on the ssd and data on the 5400rpm HDD? Could you please suggest a good price for both HDD? It seems that adding an SSD is a bit much on my budget... if not maybe I'll just stick to the 1TB 5400rpm...

No worries mate, you can always upgrade later one, so even if its a 1TB (5400rpm), it will probably satisfy you for around a year or two, and when it really slows down, then its time to upgrade By that time SSDs will definitely be much more affordable (assuming we are still using SSD that time )

I would suggest adding a Crucial M500 mSATA 120GB (weight concern) or 2.5" Crucial M500 120GB.

Another soon to be RE-15 proud owner ehemm... big thanks to Prince J, Mr.Docter & marc the chat guy hehe...

Great to hear that and what colour have you chose for the laptop cover eh? I'm still struggling for the colour decision LOL...

Well I've requested black color but needs to be ordered so need to pay extra...well talk about things you do for aesthetics... well i plan on using it for some time so must also look the part right?
