    HDD temperatures?

    I'm curious to know if the temperature of my external HDD is normal. And, what would be considered the maximum "safe" operating temperature for a HDD.

    Currently, my WD 250 SATA II HDD, installed in an external enclosure, temperature is 50

    Re: HDD temperatures?

    Hello again Jeff,

    For reference purposes, I just checked the temperatures of my internal WD SATA drives and they are 31

    Bob,

    I am also using Everest. But since my external HDD is connected via an eSATA cable, Everest does reccognize it as a "Smart drive", thus the temperature is captured and displayed.

    Chalk one up for eSATA. My enclosures only handle Firewire and USB. Less than a month after I moved to external drives eSATA was available. I would have preferred eSATA as my motherboard has external SATA connections.

    Re: HDD temperatures?

    Bob,

    I bought a Thermaltake Silver River DUO #A2396 enclosure which is a combo unit; IDE or SATA HDD and USB 2.0 or eSATA connection. The PATA drives can only connect via USB 2.0, but SATA drives can use either the USB 2.0 or the eSATA connection. I bought an eSATA bracket for the back of the case that installs in one of the PCI bracket slots which has a male SATA cable/plug that connects to one of the SATA ports on the motherboard. The only drawback of using the eSATA with my particular mb (Asus M2N-E) is that it is not "hot-swappable". So, to shut the drive down and then on again, you have to shut the PC down or be quick on a reboot and use the power switch on the enclosure. Using the USB 2.0 connection, you can simply power it off and on at will. So, now you know why my questions here about temperatures. I have been using the eSATA connection and leaving the drive/enclosure on so that I can do scheduled backups with True Image.

    Yes, I could go back to the USB 2.0 connection setup and turn the enclosure on before the backup is scheduled. But admittedly, it is much more convenient to leave the drive on and data transfer speeds are exponentially faster using eSATA. However, if leaving this external drive on and having it run at a constant 50

    Re: HDD temperatures?

    Hi John,

    You are correct that those ratings are operating temperatures. Albeit that the surrounding temperature would affect the hard drive's actual running temperature, and vice-versa, I would suspect that they would be very close to each other. On the other hand, the hard drive operating at 50

    Re: HDD temperatures?

    Jeff,

    Your Thermaltake enclosure looks like a kissin' cousin for my Vantec. They both have aluminum covers which is supposed to assist in cooling. In a way, I regret jumping too fast and getting the Firewire/USB enclosure. I should have waited for the eSATA in order to get those faster speeds. If I had, I would have had the speed advantage... and the ability to get temperature readings. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    One of the reasons I selected Firewire was that it is supposed to be faster than USB 2.0 when used with applications like backing up. I have run tests using both the Firewire and the USB connections and can report that the results are almost identical... contrary to some published reports that I should have about a 20% improvement using Firewire.

    Considering I have two externals, both of which are operating with IDE HDDs, I'll have to stick with that configuration for awhile. Unless, of course I accidently drop one of the units and would be forced to replace it with a eSATA unit ! <img src=/S/innocent.gif border=0 alt=innocent width=20 height=20>

    Re: HDD temperatures?

    Bob,

    Actually, I have owned 2 of those Vantec NexStar 3 enclosures; both USB 2.0. They are beautiful and work great. I sold one to a client and gave the other to my wife as a Christmas gift with a new HDD enclosed. The differences between the Vantec and the Thermaltake are: 1) Finish...... without doubt, the gloss finish on the Vantec units are spectacular. The Thermaltake units are a semi-matte finish. The quality of both is excellent. 2) Size...... The Thermaltake enclosure is a bit longer than the Vantec. This may be due to the "convertible" layout, i.e., the extra switches and ports to allow both USB 2.0 and eSATA? Vantec also makes an eSATA duo and dedicated enclosure now.

    Yes, it is very true that Firewire has been over-rated, IMHO and in all the tests and reports I have read, there is very little, if any difference between the two re: data transfer speeds. I can tell you that there is a noticeable difference between USB 2.0 and eSATA transfer speeds, which I am sure you would expect. hehe

    All you need to do now is find someone who really needs an external enclosure for backup purposes, sell one of your Vantec USB/Firewire units and buy yourself one of the eSATA enclosures. <img src=/S/evilgrin.gif border=0 alt=evilgrin width=15 height=15>
