A while ago I was view putting low - powered 5400 RPM drives into a NAS . I was upset about performance , butTom ’s Hardwareshows us that push back speed is n’t the chokepoint , and how ho-hum drives can even drum faster ones .
The main chokepoint in any NAS is the RAID engine . Since many NAS units do n’t include a dedicated restrainer , oftentimes the speed of the drive just does n’t matter . If you ’re using a blazing - fast computer hardware foray add-in in your own customs duty built apparatus , then motor amphetamine might make a difference . But for most consumer units , the accountant is the bottleneck .
With that in mind , you may go with dim 5400 rev drives that reduce power consumption , generate less heat , and will likely be less up front too . Even if you have a dedicated RAID card that could let a 7200 RPM crusade do it ’s thing at full speeding , I ’d consider the benefits of low - mogul driving force to outweigh the fringy stop number increase you might see .
This chart shows the difference between Samsung 7200 and 5400 RPM campaign in various maraud configurations :
Not much , right ? So believe twice before you drop more than necessary on 7200 revolutions per minute drives for your backup unit . Check out the contact for the full test rundown . [ Tom ’s Hardware ]
