P-7811 FX Hard Drive

Hey Guys,

Sorry for the noob question but, can somebody please let me know if this hard drive will work on the P-7811 FX?

Seagate Momentus 7200.4 ST9320423AS 320GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive

It is on sale: here is a link to it: Newegg.com - Seagate Momentus 7200.4 ST9320423AS 320GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive -Bare Drive

Will I need anything additional or it is more like a plug-n-play? Will I need brackets, etc.. I believe this is the same drive we have with just a larger capacity..

Please let me know. Thanks in advance...

 

As far as I know there are only 2 sizes of laptop hard drives. One is the normal one and the other has more depth to it and is more rare. This hard drive does not appear to be the rare one. You shouldn't need a bracket because there is the extra one that comes with the laptop.

Edit: What is with the ultra-low 4.17ms latency? Is that not factoring in rotational latency?

 

Try the $80 500GB Hitachi drive available at amazon and newegg. I bought it to replace my piece of 500GB seagate that constantly clicks and pauses.

Thank you both, I bought the Seagate one b/c I thought it would sell out.. Guess it didn't.. If I have issues with it, I will get the Hitachi...

Isn't the seagate what comes in our laptops???

 

No the stock HD is Hitachi.

 

Dang - I was hoping it was the same drive. If for no reason other than me being anal retentive

I assume the name brand make absolutly no difference.. correct?

 

No some brands might be more reliable and different models will have different benchmarks.

 

HELP!!! Is there anything I need to do???? I installed the drive but, it is only showing 298 GB; why isn't it showing the full 320...

 

This is because, for marketing reasons, storage devices consider 1 gigabyte to be 1 billion bytes. In reality a gigabyte is actually 2^30 bytes which is about 7.3% more than 1 billion bytes. 320GB/1.073=298GB.

 

Its simply because 1 GB=1024 MB everywhere except in the case Storage Drive manufacturers where 1 GB=1000 MB. The OS then reports it as per 1GB=1024MB, so its always less than advertised capacity. Wonder why can't the manufacturers follow the standard.

 

IIRC, you lose some drive size with NTFS formatting. Example, my 80gb SSD is seen by windows as 74.6gb.

 

Thank you all; great info..

Now I feel a little smarter today...

I appreciate all the feedback.

 

Nate, the calculation is like this
For HDD manufacturers - 1000Bytes=1KB, 1MB=1000KB, 1GB=1000MB

So 80GB = 80000MB = 80000000KB = 80000000000Bytes

Now the OS sees it like this

80000000000 Bytes = 80000000000/1024 KB = (80000000000/1024)/1024 MB = ((80000000000/1024)/1024)/1024 GB = 74.5GB

Looks confusing, with so many zero's. The calculation has to start from bytes.

 

BTW, A LOT of Seagate drives have been failing as of late, so luck of the draw to you. Hope yours doesn't fail.

I usually trust Hitachi and WD drives.

 

Ok; not sure if I should start a new thread or piggyback off of this one..

But, what are you guys using the 2nd drive for/how are you using it? I was thinking of putting most programs I install going forward on the 2nd drive. Will moving most programs to the 2nd drive (programs that aren't used often) speed up my system.

I was thinking of having only the Windows 7, virus protection, and web browsers on the 1 drive.. not sure if there is any benefit to this... Opinions???

The 2nd drive will have office 2010, cd/dvd software, etc...

 

The outside part of a hard drive is the fastest part, so moving programs from the inner part of your first hard drive to the outer part of your second hard drive would definitely improve load time. Plus boot would be faster because your OS would be loading from one drive and your programs from the other at the same time.

 

I use mine for backup.

If your second drive is the same size as the first you could always setup RAID.

 

My stock drive was a Seagate, not Hitachi. I'd stay away from the Hitachi if you can, they are poorly manufactured drives. Seagate is second only to Western Digital if you ask me. You shouldn't have trouble with that 320GB, although I had to RMA that exact model. It was working, but it had a persistent bad sector so Seagate sent me a "new" refurbished one.
I can't hurt to register your drive with Seagate once you get it just to make sure you are fully covered under warranty.
I did a Raid 0 and didn't like it. You should just use it for extra storage in my opinion. Raid was a pain and it didn't yield much performance increase. It doesn't even help for games, only for video editing and encoding and such.

 

I hear of nothing but problems with Seagate and Western Digital drives all over the Internet and never hear of problems with Hitachi HDD's! You yourself said you had to RMA a Seagate HDD, and Windows 7 wants to check my Seagate HDD for problems/consistency EVERY time I restart Windows!

How can you recommend Seagate and Western Digital over Hitachi?

By the way, Hitachi's line of notebook 2.5" HDD's used to be IBM; Hitachi bought it from IBM several years ago when IBM sold the division.
