WD Caviar SE Serial ATA (SATA) 250GB is not just all about capacity, it is also lightning fast drive. If you are need of a fast and big drive, WD Caviar SE Serial ATA (SATA) 250GB is very good choice. Especially RAID performance was very good and although price is quite high you get what you are paying for: fast, a lot of storage space and reliable drive with 3 year limited warranty.
36db operating noise is quite high but it is just a little annoyance. I was surprised how cool drive was during operation compared to other 7200RPM drives. As a whole I liked WD Caviar SE Serial ATA (SATA) 250GB very much and if I had to build RAID 0 these drives would be definitely my choice.
