Fujitsu_mhw2160bjSamsung announced their 5200 RPM, 160-gigger in November, while we’re expecting Hitachi’s 200 GB, mobile device drive in the first half of this year. Fujitsu is upping the speed with an announcement today: by the end of May we should see 160 GB, 2.5-inch drives running at 7200 RPM to compete with Hitachi’s 7200 RPM offering. Speed and capacity are great, but what the drive does to the battery is the key on a UMPC or other mobile device. Fujitsu’s press release says we should expect a power drain of 2.3 watts or less when reading or writing to the MHW2160BJ drive. I’ll have to do some digging on how that compares to our slower 4200 5200 RPM drives that are prevalent in the first gen of UMPCs, although I’m betting our friend Steve might have some info to share here.

  1. I have used and tested and compare the Hitachi 100 GB at 7200 RPM in my eo v7110 and I could not find any difference from the point of view of power drain vs the regular HDD of 5400 and 4800 that regularly was shipped with eo V7110. And when I compare my eo scores to other devices using 4800 RPM you could see how much the 7200 RPM HDD helped in the overall performance.

    2.5″ HDD use around 1W to 2W.

  2. But when are we going to get Vista Drivers from Samsung

  3. Here’s a pretty good analysis of power consumption by component, albeit for a 42oo rpm HD:

  4. Here’s another good article with a wider variety of hard drive types:

    Note that Table 2 shows both current drain and voltage, hence you can easily calculate an approximate wattage…
