i want to use ssd as system drive(for installing os software and games)
i want to use hdd as storage only
like storing game setup files ,movies , pics , musicetc
so should i go for 5400rpm 2tb wd hdd or faster 1tb 7200rpm hdd?
is thtere any noticeable difference in spped?
when to use 5400rpm hdd and when to use 7200 rpm hdd?
 
Solution
If that was true, it's not going to change the fact that, even on a 450 watts system, it will constitute only 0.3% of his power bill for his computer. In short if his computer costs him say 300 rupees a month, the faster HD would cost him less than 1 rupee a month for the fastest drive available.

https://en.wikipedia.org/wiki/Electricity_pricing

The above reference (March 2014) lists the following worldwide electricity costs In US cents per Kw-hr:

India = 0.1 to 18 (average 7)
US = 8 to 17

So if anything, Indian electric rates are 30% cheaper than the US which averaged 10 in 2014.
the 54oo rpm is more often used in laptops, because they use less power. They can be used in a desktop.....but normally not. Yes, you will notice a difference in speed between it and the 7200 rpm. I am using the same setup. My ssd is my system drive and I use a 1tb WD Black drive for storage. I chose Black because its geared more toward high performance. It has more buffer and is faster.
 
yeah lets stay in the realm of 7200 drives if possible. I found the entire WD series to be unnecessarily over priced. Check out the toshiba p300 and x300 drives. Great price for performance. For just storage 5400 is fine, but why get it if a 7200 is the same or nearly the same price.
 
Be aware of some limitations of your 250GB drive:

1. 250GB is what the sales people call it. It actually has room for only 232 GB if actual files.
2. You want to keep 15% of that free so that it can handle garbage collection and maintain optimal performance; that gets you down to 197 Gb. Windows will take up < 50 GB the day you install it , but within 6 months it will 'grow' to 80GB or more depending on how astute you are in cleaning it out. That leaves just 117 GB.
3. I'll assume you have only 45 GB of program files and that leaves 72 Gb for games.... GTAV takes up 65 GB

In short, even at 250 GB of size, you won't have room for many games. Unless your ready to up that to 500 or 1000 GB, having afast HD will be important of that is where your games will be.

Yes, all things being equal, a 7200 rpm drive is 5% faster than a 5400 rm drive. As I am sure you are aware, the WD Black is WDs premium performance drive and is significantly faster than the Blue.

In THGs gaming benchmark the $115 WD Black comes in at 6.34 MB/s and costs. The 7200 rpm WD Blue is $74 and comes in at 4.01 MB/s here but expect the newer ? larger models to be a bit faster

OTOH, the Seagate SSHD comes in more than 50% faster (9.76 MB/s) than the WD Black and is only $14 more than the WD Blue

We have both desktops and laptops equipped with SSDs and SSHDs and, as of yet, no one has been able to tell (w/o running benchmarks) which one is which.

Booting of the SSD takes 15.6 seconds
Booting of the SSHD takes 16.5 seconds

You will get the greatest befit from a SSHD is you tend to play games sequentially and less so if you are going to say play 8 different games in one night. For example, when you are playing Far Cry 3 ... all your FC3 files will be moved to the SSD portion of the drive.... once you start playing FC4, the FC3 files will be moved from the SSD and replaced by the FC4 files... quietly in the background with out you needing to do anything.

A situation like this left most power users using an SSD for their operating system, while still running a secondary mechanical drive for storage and games. A typical setup such as this would allow the OS to load very quickly, while leaving you stunned at how long it took to load a game. With the introduction of the Desktop SSHD, Seagate has again switched up the game, offering a substantial performance boost to those of you in this situation.

Now, if you are one that chooses to use a single drive for your operating system, and have held onto your standard desktop HDD for the benefit of capacity, the Desktop SSHD is calling your name. The 8GB of NAND cache in conjunction with Seagate's application optimized algorithms should offer a tremendous performance boost, and again the more you use, it the faster the drive will get, as it learns how you use your system.

In every case seen here today, the Seagate Desktop SSHD excels, whether it be a synthetic point and click benchmark like HD Tune or ATTO, or even application traces via PCMark 8, the drive just performs.

SSDs have come down so far in price that it is often hard to say 'don't get one" except in really tight budgets where the choice is between adding an SSD and getting the next more powerful GFC card. In that situation, we recommend "SSHD + GFX card upgrade". But once ya get past that budget level, an SSD is almost an automatic. However, an SSD + SSHD puts a 50% performance increase on the games that do not fit on your SSD and a 50% performance increase for $14, I consider it the proverbial "no brainer".
 
if you want to go with higher transfer speed then go for 7200 rpm hdd and if you want to decrease the cost and have low powered psu then go with 5400 rpm hdd. the higher the rpm the higher the speed and higher power consumption. lesser the rpm less speed and low power consumption.
 


Thats true, but I think most drives now have some sort of power throttling tech when idle. Since hes using the drive purely for storage I doubt the power savings would be worth it.

 


agree with you.
he is using the 250Gb ssd so if he is going to use high end games on the machine then he will surely more power so it would be better to go with 5400 rpm speed.
but if he is going to run out of storage space then he might install games on HDD that means he need speed. so his PSU is powerful enough then he should go with 7200 rpm.

 
Let me clarify myself friends
I will only install one game at a time then after successfully finishing that game I will uninstall it and install the next one

My guessed specs are
i5 4690 non k
Asus h97 pro
g skill rip jaws 2x4gb
550 w psu from either seasonic or xfx or evga
Msi gtx 970 4G twin frozen
 


according to your given solution you should go with the 5400 rpm HDD.
 
i dont know exactly why wd blue 2tb has 5400 rpm but i guess that 2tb hdd consumes more power so to balance the power it comes with 5400 rpm. still m not sure about that. but you should go with wd. because it is more reliable in service than segate and it will give proper service to you. when ever you will require warranty services. but there is not much difference in between them. segate is cost effective but power consuming where as wd is costly but power saving. its ur call. both are good.
 


A HD pulls about 5 - 8 watts, a 10k Raptor about 10-11 max...SSD less.

At idle we are talking 3 watts for a green 5400 rpm drive and 4 watts for a SSHD. Running HD video we're talking no change. At max write throughput, those numbers are 4 and 6 watts

And, yes, he will run out of storage space on the SSD, by the time you account for the base 10 size cheat and the 15% recommended free space, you are down to 197 GB, with Windows and his programs I expect taking up at least 100 within 6 months, that leaves less than 100 GB remaining. With Witcher 3 at 40 GB, GTAV at 65 GB, you're done.

Again, in gaming

Fastest Option = 2 TB 7200 rpm SSHD = 9.76 MB/s (6.48 watts max with streaming writes)
Fastest 2 TB 7200 rpm drive = Seagate Barracuda 7200.14 = 6.56 MB/s (6.60 watts max with streaming writes)
Fastest 2 TB 5400 rpm drive = Western Digital RE4-GP WD2002FYPS = 5.67 MB/s (7.83 watts max with streaming writes)
Most efficient 2 TB 7200 rpm drive = Western Digital RED WD20EFRX = 5.10 MB/s (4.8 watts max with streaming writes)

The WD Blue (4.01 MB/s) with just a single platter drew 9.48 watts, I expect the 2 TB model, even with the extra platter, to be more efficient

The fastest option is actually the most efficient option among the 3 "fastest choices" and certainly will have no impact on PSU size with a difference in wattage of just 1.32 watts. The most efficient drive in the test draws just 1.38 watts less than the fastest choice. You need about 35 of them to consider a larger PSU size.







As per the above .... neither brand, nor rpm is a reliable indicator of power consumption.

At 1.68 watts between the fastest option and the most power efficient option, assuming say 30 hours of hard gaming / streaming per week, ya looking at:

30 hours x 1.68 watts x 1/1000 watts per kilowatt x $0.10 average US electric cost x 52.14 weeks per year / 0.85% PSU efficiency = $0.30 or 2.5 cents per month.
 
The guy who is asking for the help is i think INDIAN. so the cost calculation for electricity boll differs. in our country (INDIA) mostly we go for cost effective solution. performance vs cost ratio is considered.
 
If that was true, it's not going to change the fact that, even on a 450 watts system, it will constitute only 0.3% of his power bill for his computer. In short if his computer costs him say 300 rupees a month, the faster HD would cost him less than 1 rupee a month for the fastest drive available.
