Pros and Cons of Seagate 1.5TB 7200.11 Hard Drive

We use a lot of hard drives in our Desktop RAID system, such as Seagate 7200.12 1TB, 7200.11 1.5TB, Caviar Green 1TB, 2TB. Among all these hard drives, Seagate 7200.11 have the highest performance in terms of disk access/transfer or read-write speed that no other can even compete. Based on our test, all green series will be much slower compared to Seagate 1.5tb. And most importantly, its price is almost the most reasonable if you calculate on a $/GB basis. For example, we tested that copying a very large folder 3800 files/7GB from a standalone Seagate 1.5Tb disk to a 3-disk RAID 5 configuration in our Desktop RAID system only takes around 1 minute, but for all green series it will take 3~5 minutes to finish the job. We found Caviar green is almost the slowest hard drives among all our selection since it stop running when idle.
The downside is it's very hot when running non-stop, especially when you put several Seagate 1.5TB together. If you have no cooling system in place, system will begain losing disk one-by-one, which means it's no stable enough without cooling system in place, so our Desktop system has special AI cooling system installed to guarantee their working non-stop. The normal working temperature for Seagate 1.5TB is 0~60 degree in centigrade and if your hard drives has worked more than 5 hours, it may reach much higher than 60 degree. So, our suggestion is if you have only one disk installed, it may be ok without cooling measures, but if several hard drives in one case, you have to install cooling system, otherwise your system would be dead for sure.
Green series like Seagate 7200.12 or Caviar Green has much lower working temperature, so it can work non-stop stably although disk access rate is slower.
In a word, if you want performance, you have no choice but Seagate 1.5TB, but you need to install cooing system to gurantee it can work non-stop stably. But if you have no such mission-critical needs and wish a very quiet desktop, we would suggest you go green, although a little bit slow in reading and writing.
