Sony VAIO FZ-140E: A 4200 RPM SATA HD??

Hi all,

Just wondering... Have a Sony VAIO FZ-140E Laptop with 200 GB SATA hard disk (BUT 4200 RPM). Though the performance of the machine is not bad but I was just wondering that why only 4200 RPM. I thought that SAT offers a minimum of 7200 RPM

I guess a stupid question but will appreciate your reply/comments. Why did Sony put in a slow HD when the laptop is pretty nice; in looks and performance.

Would a 7200 RPM (or maybe higher RPM hard disk) have made a considerable difference?

Thanks.

 

sata doesn't really mean anything in regards to the rpm of the hard drive.

if you jumped from 4200rpm 200gb to a 7200rpm, you will see a significant difference (also the higher the hard drive space, the more differnece you will see, because with more platters, less time to do stuff - meaning the 200gb 7200rpm drive right now will be a huge difference over the 200gb 4200rpm)

and getting a 250gb 5400rpm is usually the same overall speed or faster as a 100gb 7200rpm (more platters, etc)

def uprade the drive in my opinion....

 

Hi kickace,

Thank you for the reply and also for helping me correct my understanding i.e. I always thought that SATA simply meant higher RPM's. I guess I have to google out what SATA actually means.

I'm surprised why SONY decided to put in (what I'll refer as) an "inferior component". Not sure if I can get the harddisk replaced (for my model) and with a 7200 RPM and maybe higher capacity ??? Besides I assume that if it's possible, the hard-disk will probably cost an arm and a leg?

 

they put it in there simply because of the high space but they have higher and faster drives already out so who knows - 200gb 7200rpm will fit fine in your computer and just to give you a little gift...

a 200gb 7200rpm drive normally is about $225b but at best buy, theres a external hitachi 200gb 2.5" (laptop size) hard drive for $150 ($130 on sale but dont know if the sale is still on)

the box sais its a 5400rpm but it has been confirmed that if you look at the bottom serial number - if it starts with DTG, it infact has a 7200rpm drive....meaning run to your best buy now because you won't find one cheaper. it has to start with DTG though so make sure the serial on the box sais that, and dont' go online cuz u never know which one you'll get

so you get both a 7200rpm drive and an external case so you can put your 200gb 7200rpm in ur notebook and the 200gb 4200rpm drive in the case and use it externally

 

and the difference between sata and pata (ide) is that parallel ata can only transfer up to roughly 133mb/s

while serial ata can transfer up to roughly 600mb/s - sata right now i believe is only up to 300mb/s right now, but it will improve.

but ofcourse, the rpm of the drive also limits how much it transfers per second so unless you have a hard drive that can go faster than 133mb/s then - rpm is the real difference
