Regarding head parking, as TBorgeaud said, for some drives it can be disabled by setting the APM to 0 or delayed to such an extent that it wouldn't be a problem by setting APM to a very low value. If that doesn't suit you, I'm sorry, there's not much I can do about it. I'm not trying to convince you to go either way, I was merely stating my opinion based on my experience. Of course the importance of each criteria may (and will) vary from person to person.Īlthough I would prefer a smaller drive I don't mind having a "bulky" drive (in my desktop) if this brings benefits in other areas of higher importance to me. The Scorpio Blue only won power consumption and size. The criteria I was evaluating the drives were: noise, vibration, power consumption/heat, capacity, price, size and speed. Other than that and cost, why would you go with a 3.5" instead of a 2.5"? You seem to be basing your decision on theoretical assumptions rather than observations and experience. What are the things considered? I don't know how much performance you need, but it's not an issue for me. Thanks.ĬTT wrote:At a certain point I was also all set to go the 2.5' way but all things considered (including here the fact that I still have plenty of space) I've chosen to stick to low power 3.5' drives for the time being. Snurtur: Could you please adjust the attribution of quotes in your reply to CTT's message. However, it's quite easy, and often desirable, to have some form of access occur on a sem-regular basis with period short enough that any clicking becomes annoying and additional wear and tear may actually become a concern. This is unlikely to be a problem with a drive that is accessed very infrequently. If a drive is not accessed very frequently, this basically results in heads being unparked and then parked again on virtually very access. The head parking problem that I came across, and one that has been seen by others with other drives, is that drives park the heads, often with a very audible click, after quite a short period of inactivity.
However, since any potential (minor) problems will be dependent upon exactly how the drives will be used, it's probably worth being aware about the APM features commonly found on smaller disks. How do you use the drive? What's bad about the head load/unload cycles? Does it cause wear and tear? Does it make a lot of noise? Does it make the drive unsuitable as a slave storage drive in a desktop computer?įor the use that you intend, I wouldn't predict any problems due to aggressive APM features.
