Should I get the Seagate 4TB or the WD-Green 4TB for storage ? - Page 2

If I keep the drive in tower hooked up and I only power on the PC for a few hours during the day and it happens that I don't need to use that drive during the time then technically the Green drive should only need to park and unpark a few times at the most, correct ? Basically I'm asking will Windows randomly often access the drive with no reason ?

Head parking works like this: simply within the drive there is the platter and the arm, on the end of the arm is the head, this is what reads and writes the data, the arm is moved by the actuator. You can save power by not having the platter spin all the time but how do you do this?

The arm and the head are kept in suspense above the platter of the drive under normal operation by a cushion of air, this cushion is formed by the platter spinning very very quickly, as people have said in this case around 5400rpm. This stops contact between the platter and the head, when they do come in to contact this is called a head crash and the drive is irretrievably damaged, this will also mark the platter and (if you rip the drive open you would be able to see this). Essentially whats happening is similar to an ice hockey table, the puck is kept in suspense above the table by a cushion of air but with a bit more magnetic recording. This height is called the flying height.

So when the drive doesn't spin fast enough it causes a head crash and the drive is damaged, modern drives don't do this or at least try very hard for this not to happen. They employ a system called ramp load/unload. Before this a system called Contact Start and Stop was used; this involved having a section of the drive that would be dedicated to being the landing zone, this part would get touched by the head and used when landing and launching, this section had to have no data on it as it was allocated to be damaged. Now a ramp is used off the platter, this has a shallow incline for the head to slide on and off the drive when not in use.

Basically what this all means is the Green is designed to be environmentally friendly (If the fact that WD's marketing called the drive the Green isn't an indicator its designed to use little power; then I don't know what is.) It can slow down its spindle speed 'intellirpm' (its actually not clearly stated by WD so 5400rpm could be its max speed and it could hover around a slower speed to improve access time and lower power consumption?) or possibly stop it entirely and it can do this safely due to a ramp load/unload and this process is called head parking. I know I rambled a little away from your original question that I'm quoting but this interests me so I thought why not. It might help you or some one else reading it.

Anyway back to your original question: if it wasn't for head parking and ramp load/unload or APM then yes the heads would launch once the drive was going at a good enough pace and then would land again when you turn the computer off and the head would only be parked once when being turned off. The Green will do this process after 8 seconds of inactivity, this can be particularly annoying when listening to music or watching a movie. Its a constant start, stop process to lower power consumption, reduce heat and in the interim lower noise levels. How well the last one works is debatable. Windows won't access the drive again randomly after boot unless Windows Explorer wants to index the drive - I'm not too sure about how Explorer does this but I can't image it will be a problem. What will access the drive would be steam or an anti virus scanning the file system, it can all be disabled via wdidle3. I wouldn't imagine the head parking to be that much louder than the fans, how much of a problem it is depends on how loud your fans are, your ambient noise and how close to your desktop you are.

Between the Seagate and WD my money would go to the WD, its cheaper, both are 5400rpm/5900rpm drives so no miracles performance wise, its just cheap storage and for that the WD with its better warranty service.

I agree with you, I would get the WD in this situation as well due to price. I just wanted to point out that they both (Seagate and WD) have the same warranty options, what is the advantage of the WD service?

OK so while they have the same warranty length, a fairly pathetic 2 years; on the whole recently warranties have slowly been getting shorter for consumer drives, whether this is something to do with their now being just 3 players (Seagate, WD with part of HGST and Toshiba with the other part of HGST) I don't know but anyway WD offer an ARMA, this is an Advanced RMA, they'll send you a replacement drive before you send in your failing drive, the drive has to be verified as faulty by WD customer service first (obviously) and I believe they do this by asking you to run WD LifeGuard on the drive, I haven't done an ARMA so I'm basing this on the experiences of others across the internet. With the ARMA WD have to receive your faulty drive within 30 days from the RMA being opened otherwise you will be billed for the replacement drive.

This is particularly useful for customers wanting to minimize downtime so I'm presuming small businesses and people running RAID arrays wanting to maintain the uptime of their service.

Seagate don't have a service where they send you your replacement drive before you send in your faulty one and its a great service offered. I suppose its also a tactical offering by WD, typically your going to have to buy another drive to back up the failing drive and get data off of it but who do you buy the replacement from? This service keeps you with WD, while I know any RMA is going to keep you with said brand but this really keeps you with WD. EG you haven't bought Seagate's drive to get a copy of the data from the failing drive, you still have it.

WD are also far less picky about the packaging of the drive you sent it off to them in, off the top of my head I think the requirements are an inch of foam or similar around the entirety of the drive to keep it safe, they're quite relaxed about this whereas Seagate can be quite pedantic about what the drive was sent to them in. Also you can send your faulty drive to WD in the packaging that your replacement drive came in if you opted for an ARMA.

WD are also quite quick at the turnaround for the drives, for an ARMA is about 3-5 business days and for a normal RMA around 5-7 business days.

Edit: CHIZ is right below, Seagate do have an advanced replacement service but this is only for the US and Canada. WD offer their service in Europe as well as US and Canada. It is nearly identical to WD's ARMA. Seagate's service seem a little slower for the free Ground Advanced Replacement but offer a Premium service for $10, this is slightly faster / near the same speed as WD's service.

I do like the RMA of WD drives. I got a 1tb drive for free with a busted connector and they rmad it without proof of purchase due to still being under warranty.
And i have a WD green in my main rig now that's still going strong. the green drive i had going bad was one i had gotten off of fleebay.
With warranty being brought up and $20 cheaper, not being used for an OS, and only for storage every now and then. The WD green seems to be the most sensible option.

Just as a heads up, Seagate does offer an advanced RMA option, it works nearly identical to the WD ARMA. I agree with you though, Seagate's packaging instructions are much more picky than WD's.

One thing I don't like about the Greens that after 10mins or so the drive spins down. The reason why I don't want it to go to sleep is because when it goes to sleep you have to wait for the drive to wake up and also wake up if you want to power off the PC so end up waiting for it to spin up before the PC shuts down. So I was told and confirmed by others that tweaking the settings in the power options plan and change the default 20mins hard disk sleep to never that the Green drives will never go to sleep. I want to ask here first is there any cons in doing this ? How will this affect the head parking issue by the drive never spinning down ? Does it mean the head will never park ? is this bad a idea. You guys been great, thanks

If you don't want the greens to sleep as they are supposed to save power, check out this little program.
http://keepalivehd.codeplex.com/
you can select which drives to keep awake. My advice, get whichever hard drive you want after this thread, download that program but dont use it yet. if you find you are waiting for your files to be accessed often then start using the program. or start using it for a week and disable program to see fi you notice any difference. either way, i hope this program should help you.

Thanks, but why use that 3rd party software when just simply changing a setting in the power plan options easily fixes the problem of preventing going to sleep. I just want know if there are any cons in doing so with the greens.

Not really any cons except more power on hours added onto the drive. but if you want them to go to sleep and keep your main drive awake that's where that software would come in handy. windows does not have the functionality to only make certain drives go to sleep.
