Select replacement internal hard drive for Dell XPS 1730 laptop

Last Modified: 2012-06-21
I need help selecting a replacement internal hard drive. My Dell XPS 1730 came with two Hitachi 200GB 7200RPM internal hard drives. These were 2.5 inch SATA drives. I have used them in RAID 0 (striped) configuration to maximize the usable hard disk space.

One of the two internal hard drives has crashed and I need to replace it (again). The first time it crashed, I replaced it with a WD 250GB 7200RPM hard drive. That drive crashed after more than one year and I replaced it with another WD 250GB 7200 hard drive. Now... this one has crashed after a little over one year.

I had backed up my entire computer (Windows XP, applications, and data) with both Acronis and Paragon.

I live in a small town in Costa Rica and have gone through three internal drives and four external drives in more than three years. I have a problem that no one else in my town is having, and I'm looking at that and will probably post a separate question about that.

My immediate need is to order a new internal hard drive from the U.S. very soon. Since prices of hard drives have dropped so much, I want to buy a 500GB 7200RPM hard drive. I want to make sure it's suitable for my Dell XPS 1730. I think it's OK to replace a SATA drive with a SATA II drive, but I don't have much technical knowledge. I just google for info on the web.

I'm looking at http://www.amazon.com/Western-Digital-Scorpio-Black-Mobile/dp/B004LR1RPK/ref=pd_cp_e_1 and http://www.amazon.com/Hitachi-Travelstar-Cache-Internal-0S02858/dp/B003SX0ORA/ref=sr_1_4?s=electronics&ie=UTF8&qid=1320368133&sr=1-4.

I'm open to any 500GB drive of good quality that has a fair price (for the quality). There are lots of hard drives brands, many of which I've never heard of.

I will appreciate your recommendation and brief explanation why you think it would make sense.

Thanks for your help.
