Hi,

I have the Dell Inspiron i7559-763BLK laptop which has the following specs:

Intel i5-6300HQ 2.3 GHz Quad-Core (6M Cache, Turbo up to 3.2 GHz)
NVIDIA GeForce GTX 960M 4GB GDDR5
8 GB DDR3L / 256 GB Solid-State Drive
15.6-Inch FHD IPS, Wide-Angle, Anti Glare Screen.

I'm interested in adding another 2.5 1TB storage hard drive but I have some questions
I found the following drives on Amazon.com
1. HGST Travelstar 7K1000 2.5-Inch 1TB 7200 RPM SATA III 32MB Cache Internal Hard Drive 0J22423 ($63)
2. HGST Travelstar 2.5-Inch 1TB 5400RPM SATA 6Gbps 8MB Cache Internal Hard Drive (0J22413) (HTS541010A9E680) ($49)
3. Toshiba 1TB 5400RPM SATA3/SATA 6.0 GB/s 8MB Notebook Hard Drive (2.5 inch)- MQ01ABD100 ($49)
4. WD Blue 1TB Mobile Hard Disk Drive - 5400 RPM SATA 6 Gb/s 9.5 MM 2.5 Inch - WD10JPVX ($58)

I'm a student and battery time is somewhat important for me, I've read that 7200rpm drives consume much power than 5400rpm drives. the battery lasts about 6-7hours on this laptop, what should I expect in terms of power consumption after adding a 7200rpm drive? if the difference is only about 10-20minutes that is not a problem for me.

Is the performance difference between 7200rpm and 5400rpm noticable?

Based on the above questions, what drive should I get?

Please note that this is only a storage drive as my operating system is on the SSD and I will not be accessing it frequently.
 
Solution
I'd go for the WD Blue, option 4. 5400 vs 7200 rpm won't have a noticeable difference, especially if you're only using for normal file storage.
