Western Digital, I want to buy a hard disk desktop, c 1 door. The black one is too expensive. There is something wrong with Seagate's firmware. Hitachi Samsung's has never been used. Please give me some advice. What to buy. 1 and 1 in Western Digital only have green disk and notebook blue disk, so you can choose blue disk besides black disk.

2. There is something wrong with 2.Seagate firmware. That is an old calendar book. Now all Seagate disks in this series have no firmware problems.

3. Don't buy Samsung. The after-sales service is too bad. Hitachi is good. 7K 1000C and 7K3000 are both good quotations. I haven't heard of any big mistakes made by Hitachi. It has been very stable.
