Hitachi 0S03339 Review by Ron (Boston, MA USA)
This is a fast, quiet and reliable Travelstar 7K500 drive in new retail packaging. Label on my drive indicates P/N: 0A72335 and my system enumerates drive as "HTS725050A9A364." Seems Hitachi markets these drives with various item numbers including: HD20500IDK/7K, 0S00157, H2IK5001672SP and 0S02858. I have three different retail boxes purchased over the past year or so and while they do have different item numbers they all contained drives with P/N: 0A72335. The packaging shown above seems to be the latest as of Aug-2010.
UPDATE: Sometime during the summer of 2011 Hitachi began shipping 500GB advanced format 7K750 drives in the same packaging as drives noted above and labeled with the same part number: 0S02858. Good news is that a 750GB, 7200RPM model is now available. Bad news is that older OS's and some cloning software may not "align" sectors properly for good performance. Hitachi offers an Align Tool on their web site to address this issue. I have no experience with these new advanced format drives, but felt I should update my review in light of recent changes to the product line.
Hitachi 0S03339 Review by Arun K Patra
This is a good drive and meets parameters as advertised. However users who want to use it with the 13" mid 2010 Macbook Pro, please be warned that this drive is not supported by Lion. Apple has still not allowed a 7200 RPM 3.0 GBps drive for the 13". Also the auto power down mode will not work. Your 13" Macbook pro (mid 2010) will thus have the hard disk spinning perpetually. You can stop the hard disk to spin only when you shut down the machine. This will drain your otherwise 7-9 hour worth of battery to 3-4 hours. I went ahead and changed mine to the 5400 RMP drive that came with my Macbook Pro.
There's nothing wrong with the drive - just that its not meant for the Macbook Pro 13" mid 2010 Unibody. Before you buy this, confirm with Apple that the machine where you are going to use this actually supports this FULLY!
Hitachi 0S03339 Review by Abester (USA)
The internal Seagate 160GB 7200rpm HDD in my late 2007 / early 2008 MacBook Pro 15" bit the dust in February 2011. It was acting flakey the prior week so I became much more diligent at doing my SuperDuper backups daily to my external Firewire disk. Google SuperDuper if you need more info.
I initially replaced the failed Seagate drive in my MacBook Pro with a 5400rpm 500GB Western Digital Western Digital Scorpio Blue 500 GB Bulk/OEM Hard Drive 2.5 Inch, 8 MB Cache, 5400 RPM SATA II WD5000BEVT and although it worked OK, the WD drive seemed slow to respond at times when clicking on a program icon or even an email within my Thunderbird email client. I would often get the Mac spinning color wheel before a program would open. I doubt that this was due to the rpm speed differences between the drives. I'm not certain what was going on with the Western Digital Scorpio Blue drive but I am inclined to believe that there may be an aggressive power saving feature embedded and enabled in it's firmware causing it to spin down and stop frequently. I cannot verify this. Not having the software tools to check or disable it (if in fact that was the cause), I opted instead to try the Hitachi 0S02858 disk. I'm glad I did. It's so much better in this application.
The Hitachi disk responds immediately upon clicking a program icon or opening a document, reading an email, etc. No more waiting on that spinning color wheel before the disk responds. The Hitachi is also faster than the WD at opening and loading the application (excel spread sheets, word processing docs, PDF files, etc.) as it should be at 7200rpm vs 5400rpm. But again the biggest improvement is in it's initial responsiveness.
The Hitachi disk is also quiet. I can feel a very slight bit of vibration when I place my hand over the area where the disk is installed but this is not out of the ordinary and it's comparable to the slight vibration I felt with the original disk that was in my MacBook Pro.
My basic disk replacement steps:
Open the MacBook Pro. There are several pictures and video clips online that show you exactly how to do this. All you need is a T6 torx tool and a #00 Philips screw driver.
- Swap out the bad 2.5" SATA disk for a new one and reassemble the MacBook Pro.
- Boot from your external backup disk. You do have a recent bootable backup, don't you? I use SuperDuper to create my bootable backup but there are other popular programs. BTW, an external Firewire disk is so much faster than USB 2.0 but USB 2.0 will work if that's all you have.
- Once booted and logged in on your external disk, the Mac will alert you that you have an uninitialized disk in the system. It will ask if you want to initialize it. If you don't get this alert just run the Mac's Disk Utility to partition your new disk as "Mac OS Extended (Journaled)".
- Now use SuperDuper (or your other favorite similar program) to re-clone your new internal disk with the contents from your external backup (which you are presently booted from). Depending on how much stuff you have, and if you're running USB or Firewire, this may take 20 to 30 minutes or so to well over an hour.
- Now boot normally from your internal disk.
- Spotlight may begin to reindex your files but once it's done everything should be back to normal.
Additional notes: Disk Utility reports this Hitachi disk as "Hitachi HTS725050A9A364 Media" which is consistent with what other folks here have mentioned. I can't speak to the reliability of the Hitachi disk as I haven't had it long but I am extremely happy with it's performance. It is quiet and contrary to other reports (possibly on Windows), I'm not hearing any odd clicking, calibrations, or other noises.
