Fastest 2.5" 500GB Hard Drive Available-80MB/sec Average Speed Across The Volume!

ByWavey Daveyon February 19, 2010

Verified Purchase

Hitachi HD's always deliver amazing performance, and this Retail Boxed 2.5" 7200RPM 500GB SATA II notebook drive does not disappoint! Using HD Tune Pro 3.50 I charted my example from more than 100MB/sec (Actual 108MB/sec) for the highest speed it reads to a low of just less than 50MB/sec, for an average across the volume of 80.5MB/sec. That makes this HD the fastest 2.5" notebook 7200RPM HD I've ever tested, and I've tested a bunch of them--all good mind you, but this Hitachi 16mb Cache 7200RPM 500GB SATA II HD is simply the King of the Hill @ 80.5MB/sec average speed across the whole volume...just incredible!

I have uploaded the image of that performance here at Amazon.com so you can see it for yourselves, because it should be seen to be believed, and I've done that for all of you to see just how good this HD really is. The seek speed is 17.9MB.sec across the volume, which does *not* beat a Western Digital Scorpio Black 7200RPM 320GB HD, but it has less area to cover in terms of overall size, and it is a good 15-20MB/sec slower overall than the Hitachi is, @ just over 64/MB/sec for its top speed.

The other nice characteristic of Hitachi notebook HD's is their acoustical noise, or rather a lack of it, and this HD doesn't disappoint there either, as it's virtually silent as it goes about it business, reading and writing in my Asus UL30Vt-X1 13.3" notebook. In fact I cannot hear a thing from the Hitachi HD, it's that silent, doesn't make even a whirring noise, just is silent as can be for a HD...so Kudos for Hitachi Global Storage for making this the best 7200RPM 2.5" HD in the world today.

I can't stress enough how good this retail boxed HD really is, but with 16GB Cache and a fast 7200RPM speed, it really makes mincemeat out of any reading or writing assignment. And it's a nice package, the retail box itself, of course! There's the HD which is mounted inside the box in its special carrier, to prevent damage inside the box during shipping, and it's also wrapped up in a special "Moisture Proof" Electro-static Bag, which has a big packet of anti-static Silica Gel inside the bag, so Hitachi is taking no chances with the shipment of their precious HD's.

I always prefer buying a Retail Boxed HD also, because human hands don't touch them, they are always secure inside of their boxes in their special carrier assemblies, and this box and packaging is no doubt one of the best in that regard. It comes with a Seal across the top tab and flap, so you can be certain that nobody has opened the HD up and tampered with it, changed it, or stolen it! So that's a good thing too, the Retail Box of this HD itself.

With an average speed of more than 80MB/sec across the volume according to my testing, and a Burst Speed of more than 145 MB/sec, I have never seen a 2.5" notebook HD perform like this, other than a WD Raptor 10K Enterprise HD, of course...one of those will outperform this HD, but that is about it! And that HD is NOT a 9.5mm form factor so it won't fit in a notebook anyway.

This is, at this time, the fastest 2.5" notebook 7200RPM HD in the world bar none, and you can buy it here at Amazon.com in its Retail Box, secure and safe in there away from human tampering and screw-ups, and bad packaging, all of the good reasons to always purchase HD's in retail boxes if possible, so there you go!

I give the Hitachi 500GB SATA II 7200RPM 16MB Cache HD my solid 5-Stars Endorsement and approval, and recommend it over any and all other choices, Seagate, Western Digital, whatever the other choices are they are no match for this HD. This is the best, Hitachi GST's premiere 500GB 2.5" SATA II HD, and you can get it here at Amazon.com for a pittance, and have the best of all worlds: speed, big size, and the security of knowing it's going to come to you in a Retail Box, not a loose packed HD which can get into all kinds of trouble and problems being shipped--not this one!

A Warning to MacBook Pro Owners.

ByD. Porteron July 5, 2010

Verified Purchase

I purchased this drive to replace the original in 100GB 5400RPM HDD in my 2006 MacBook Pro, as I had been running low on space for a long time. I decided to replace my hard drive myself, which is not too difficult if you have a little electronics experience. If you want to do this yourself instructions can be found on iFixit.com.

Here's where the problem comes in; if you have an original MacBook Pro (the ones with the silver keys, not the newer unibody ones) the cable that connect to the Bluetooth chip and the IR remote receiver goes directly over where the breather hole is on this drive (which should not be covered). See this image from iFixit for a visual of this cable: [...]

Covering the breather hole can cause the hard drive to fail, and fast, so I had to get a little creative with the cable. I do not recommend doing this.

Since installing this hard drive I have noticed a dramatic increase in the speed of starting up, opening files and shut down on my MBP, and the extra storage is great. However, it's not worth the difficult instal, or the risk of hard drive failure when there are other drives available that work just as well. If you have an original MBP and want to replace your hard drive I highly recommend choosing a different drive that doesn't have the breather hole in the same place.

Fast, reliable replacement laptop drive

BySusurrationon April 16, 2010

Verified Purchase

I have installed two of these 7200 RPM 500GB drives now, one in a Lenovo Thinkpad T60p and one in a Dell D620. I used SiSoftware-Sandra (downloadable free) to check that the disk interface was SATA and the speed of the SATA disk controller. The Lenovo used a SATA Revision 1 (1.5Gb/s) interface, so I downloaded Hitachi's Feature Tool from [...] to change the SATA interface speed, as this drive comes with the default set to 3Gb/s. It's not difficult - you just need to burn the software to a CD, which you boot from, to change the disk settings.
I copied the existing hard drive by inserting this disk into a neat (and cheap) Vantec NexStar CX NST-200S2-BK 2.5-Inch SATA to USB 2.0 External Hard Drive Enclosure (Black) using Acronis True Image Home 2010 software to "clone" the hard disk. If you have an operating system restore partition on the hard drive - true for most Dells and Lenovos - you need to clone that partition to a partition of the same size on the new disk. Acronis will allow you to do this fairly painlessly.
Both of my new Hitachi replacement disks are *fast* and totally trouble free in their new homes. In total, it took about two hours to do the whole thing: about an hour and a half to clone the existing hard drive, about 15 minutes to swap drives over, and 15 minutes to think about things ... :-). I have been using Hitachi Travelstar hard drives for years now and I have never had a problem with any of them. I love the increased performance that this disk provides -- *and* I love not having to look for spaces to back up all of the data that no longer fit on my old drive!
