- There was some discussion on here a while back regarding the noise level of
- Western Digital harddrives. These messages were mainly in reference to
- the Caviar 2200 drives, but I just thought I would comment here.
-
- We just received a shipment in our lab yesterday of 4 more computers.
- We now have 7 computers which are all configured as 486DX-50's with 340 Meg
- IDE drives, 16 Megs RAM, etc.
- The first 2 we received had Maxtor 340 Meg IDE drives, and AT desktop case
- style A(for lack of better description).
- These drives were made a slight buzzing noise, but the noise was certainly
- acceptable. Transfer speed reported by Norton SI and Checkit was around
- 700-900 KB/s.
-
- The next computer we got had a Western Digital Caviar 340 Meg drive and AT
- desktop case style A.
- This setup had a slightly louder buzzing noise, but was still acceptable.
- Transfer speed was reported as 1100-1200 KB/s.
-
- The last 4 computers we received had WD Caviar 340 Meg drives and AT
- desktop case style B. (different case)
- This setup had absolute no drive noise. Transfer speed is still reported
- as 1100-1200 KB/s.
-
- By buzzing noise, I'm referring to normal drive access. It's not a klunk,
- it's not a kerplunk, it's just the drive head moving back and forth, and the
- platter spinning. Perfectly normal, IMO. The drives(RZ55 & RZ58) in our
- DECstation 5000/200 make a klunking noise, and are quite loud in comparison.
-
- In conclusion: I find from this that drive noise is directly related to
- case style, and location of the drive within the case. Certain cases and
- drive positions will dampen the vibrations and noise made by a HD, others
- will reverberate with certain drives and make noise levels worse.
-
- Without testing different drives and different case styles it is going to
- be difficult to identify beforehand whether a drive/case combination is
- going to be "noisy" or "quiet". Usually this experimentation can only
- affordably be performed by OEM's.
-
- On a side note we have one case where if the 3.5" drive is installed in one
- drive bay it's quiet, if installed in another drive bay it's very noisy.
