    Hey guys,

    Probably getting a 13" MBP baseline model (160 GB HD) in a few weeks. Can someone confirm how many GB's the HD is out of the box? My 200 GB Penryn MBP was actually 185 GB's.

    Thanks!

    Like 149GB?

    If you want to calculate it yourself, its simple. 160GB is really 160 billion bytes (160 000 000 000) because a gigabyte is 1 billion bytes. But for the sake of large numbers, I'll use 1.6x10^11. That number divided by 1024^3 should give you your answer in gibibytes (which are commonly and incorrectly called gigabytes by 99.9% of the public).

    The actual capacity of a hard drive in GB is 93.13% of the advertised one.

    HDD manufacturers advertise 1 GB = 1.000.000.000 bytes. In use though 1GB = 1073741824 bytes.

    So expect 7% less storage than advertised.

    If that's true than 149 GB's sounds right. Thank you!

    Just got my 13" MBP. Mine had 149 GB's out of the box but only 130 GB's available. Does this sound normal?
