Laptop Hard Drive Current?

[tdmullen]

So I'm looking around to be able to find a replacement for my dead laptop hard drive and as I'm looking around, I see laptop hard drives with varying current. The hard drive that was in the laptop is a 700mA but when i look on Ebay, I find laptop hard drives that are 800mA. Such as this one on Ebay: http://m.ebay.com/itm/HGST-500GB-7200RPM-SATA-6Gbs-Hard-Drive-2-5-Inch-/232103667059?hash=item360a74e573%3Ag%3A0TgAAOSwYIxX3ehG&_trkparms=pageci%3A7f41a8da-8ab2-11e6-8b83-005056b688cb%7Cparentrq%3A930ea2fb1570a2a597d125dfffff3ab5%7Ciid%3A2. Is there anything else I should make sure to check when replacing a hard rive besides making sure to get the right size hard drive and the connection?

Which laptop?

It's an HP Probook 655: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03326926

I have friends at a laptop repair shop. As far as I know they have never had a drive not work due to current. You should be fine. 

ps: I recommend the WD 1tb black 2.5 inch drive (it is a good size for the money, and is built like a tank).

[tdmullen]

Well I didn't think the current mattered too much. I just figured the hard drive would just use more current as it needed it. I was actually going to sell this laptop because I got a new one. I've heard a lot of good things about Western Digital drives.

It'll work. 100mA is tiny amount.

Personally if you are going to sell your laptop I would invest as little as possible in it because you will not recover the cost of the drive. It is hard to get what it is worth anymore from anyone on a laptop. I would suggest that you get something comparable to what you had in it as far as size and speed. If you want the exact same drive you can get it for under $35 new here: LINK

 

I would suggest something with a little better review  and a better warranty like this: LINK

 

Bottom line they are about the same price and it is your money. You are going to busy enough installing the operating system into the new drive anyway.

 

Good luck!

That was my thought. I was going to find something close to what I had originally instead of throwing an ssd or a 1Tb into it. Unless if I manage to find one that is ridiculously cheap. Is the type of connection and hard drive size the only I really need to check to replace a laptop hard drive?

[APasz]

Sometimes laptops will uses non standard connectors and so you must get a drive with the same connector which could prove difficult.

The software size of the HDD has no impact on installation but the physical height is something to look out for.

[tdmullen]

Well it has the typical sata laptop connector, so finding another one with it wouldn't be that difficult. I didn't think about hard drive thickness though. All the laptop hard drives I've seen look like they're pretty much the same thickness though.

[tdmullen]

I did some looking around and I found that it looks like that hard drives at 5400rpm, regardless of being sata II or sata III, are at 700mA and hard drives are at 800mA with 7200rpm for HGST hard drives specifically, which makes sense. I know that both of the connections and speeds are compatible with the laptop if you happen to look at the HP spare number. Looking around at other hard drive brands, I see that some currents range from 450mA to 1.1A. I'm not sure if it would still make a difference if I put a Western Digital or Seagate, etc. in the laptop instead.

[APasz]

Brand and RPM don't matter. Try to stick to that 700mA if possible but it ultimately isn't a problem as the power delivery system of the laptop has to meet sata standards.

[tdmullen]

That would make sense. Thanks for the info!
