Seagate 7200.4 ST9500420AS 500GB SATA Laptop Hard Drive

How We Got Here:
Looking to upgrade your Macbook or Macbook Pro? Once, I was just like you. I suffered with the small, slow stock hard disk drive (HDD) in my Macbook. Over the past few years, it had grown fragmented, was getting rather full and things were slowing down.

Where Are We Going?
Look kids, there are reletively few things you need to know about HDD. First is size. Most people know about this. My stock drive was 80gb and I knew I needed more. So do you. In fact, buy more space than you'll use. A lot more. Why? Because your computer uses, even though you're not using explicitly. A larger drive will be faster than a small cluttered one.
The other thing you may know about is speed. My stock Apple HDD was 5400rpm (revolutions per minute). This bad boy's speed rating is 7200rpm. That means data is read faster and writes faster. There's more to speed equation, but this is 99% of what we need to know.
Lastly and most importantly, size matters. The physical dimensions of the drive mean the difference between one that fits and one that doesn't. This is a 2.5" drive, which is the standard size for laptops and some compact desktops (i.e. Mac Mini).

Why Not Solid State?
The new wave of HDD are solid state. They're like massive flash drives. They're fast. Well, faster for most things. Something like writing m-a-s-s-i-v-e files is slower, but 90% of the time, they're faster. Remember what I said about RPMs above? The solid state drive circumvent this problem because there's nothing to spin. Not having to spin means faster read/write times. So why not get one? They're also way more expensive, and although prices are dropping fast, I got a lot more for my money with this drive.

The Installation
Apple has excellent PDF directions on their site for installation instructions. Here's the link for Macbooks: http://manuals.info.apple.com/​en/macbook_13inch_harddrive_di​y.pdf
I completed mine in <5 minutes and it was my first time. Be sure you have a torqs screwdriver handy (size T6, as I recall).

In Summary
There are a lot of options out there, kids, but the Seagate ST9500420AS is the best drive out there in the physical memory category. And get the ST9500420AS, not the "G" model since the the Macbook and Macbook Pro already have impact protection.

Great Way to Expand.

At first my laptop was mostly used for school projects and rarely ever for high quality web designing projects. Now that I have developed an interest and have my own freelance designing stuff, I need much more space than 100GB @ 7200 RPM. This was well worth the upgrade, I was able to use EASEUS ToDoBackup for cloning the drive and EASEUS Partition Manager for increasing the partitions. All in all, I'm thoroughly satisfied, my computer used to move so slow with all the stuff on the hard drive, now with extra allocation, it's so much simpler. I wish the they had the 750GB one, that was what I was really hoping for but this is doing just fine. I was able to extend volume dimensions on my recovery partition as well.

Great HDD, So Far

I needed to upgrade my laptop's secondary HDD - my primary AND secondary drives were filling up with photos and music. I bought this one mainly due to the price the Seller offered, but it also met my criteria: 500gb+, 7200rpm, 16mb cache. I just installed it last night but, so far, it's just great - really fast formatting and then copying to it (due to the rpms & cache). I've had other Seagate HDDs in the past, so I am assuming that this one will meet the same longevity and quality standards.

Great harddisk

The disk had the right amount of gigabites for my laptop. The rotation speed is 7200 rpm and that makes it working well. I installed windows 7 and this combination is much quicker than it was with my old harddisk with windows vista.

Good product for your laptop!

Yes, I would recommend this product to a friend.

Installed this HDD into my wife's laptop (don't forget the shock frame & adapter with micro cable). Easy installation, good product, and Seagate has never put out a bad product in my experience. It serves as the data drive on the laptop and when scanned after formatting, there was no report of bad or missing sectors.

P.S. Check to ensure that the adapter cable is long enough to reach from the HDD to the microSATA port in your laptop.
