[ASK] Hard Drive for NAS

6 posts in this topic

Good day!

this is my 1st post so Hello World! :)

few days ago I was really shocked by the poor performance of WD Caviar Green 1Tb (i tested them using dd and find out they have performance equal to 5400rpm Hitachi "somedisk"..)

i decided to give them back and now im lookin' for different class.

i know they are all good BUT I would ask you what's' the best choice among the following:

SEAGATE - Constellation ES 1 Tb Sata 6 Gb / s 3,5" Buffer 64 Mb 7200 Rpm

SEAGATE - Barracuda 7200.14 1 TB Sata 6 Gb / s 3,5" Buffer 64 Mb 7200 rpm

WESTERN DIGITAL - WD Black 1 TB Sata III 6 Gb / s 3,5" Buffer 64 Mb 7200 rpm

I'm not an expert so i hope you can help me.

bye! :D

If the drives are going into a NAS box, the WD RED drives are you best choice for the $. They are designed for NAS applications. Yes, they spin at 5x00 rpm, but in a NAS environment going to a 7200 rpm drive gives no appreciable performance increase.

Thanks for your replay,

i don't have $ problem and i have a gigabit nas, i really don't need those wd red.. i think they are like caviar green.. i want a 7200 rpm not 5*00.

thanks anyway! :)

Well if money is not an issue then just get any flavor of enterprise class disk.

And FWIW, in a decent NAS even the 5400 units will saturate a gigabit link. I run five Samsung HD204UI 5400RPM units on an Areca 1230 controller in a 2K8 server and I can easily stomp the network bandwidth. The disks are not a bottle neck.

If you think the Reds wouldn't be fast enough then I recommend the WD RE series. They cost more, but are extremely fast and like the Reds, are designed for 24/7 usage.

7200 RPM drives in a NAS add performance but there are few use cases that justify it, especially compared to the power use, thermals, etc. In our small NAS reviews (under 8 bays) we test with Reds and 4TB Ultrastars and while there is a significant performance difference, the "felt performance" is similar.
