Green Drives Suck

[pjkenned]

here's the hd tune results for my caviar green (wd6400aacs) raid 0 array when the drives were new with a fresh win 7 64 ultimate install:

for some perspective, my results are better than the guy with 4x36 gb raptors in raid 0 in max, average, and burst rate, slightly better max than the guy with 2x150gb velociraptors, a little worse average, but higher burst. i remember seeing results of 2x500gb caviar blues in raid 0 that just fell short of my array.

basically, from what i've experienced, caviar greens aren't the slow-ass drives that people like to think they are. i'm really curious to hear more specifics about the OPs situation because he must have some bad drives or be doing a very specific task or something.

op if you need near-instantaneous response get an ssd, seriously.

On the suggestion for SSD, that is generally a good piece of advice.

On those showing RAID 0, RAID 5, and RAID 6 benchmarks as evidence as to why the OP is frustrated, please understand that the most likely issue for the OP's problem is not throughput, and is instead IOPS (IOPS when t=0 and your drive is spun down = zero). Therefore, 15K 2.5" SAS drives are going to be much better than a RAID 0 "green" drive setup by a wide margin even if the 15K 2.5" SAS drive has 1/4 the throughput.

To the OP: All tier 1 storage manufacturers, Tier 1 RAID controller manufacturers, and even a lot of storage platforms such as Solaris/ZFS use tiered storage as a fundamental building principal. The idea is that one uses low cost/ slow storage to do massive archiving, and then move data to faster storage tiers the more frequently data is accessed.

This is pretty basic stuff... even consumer players are getting in like the Z68 Intel PCH and some of the low cost Marvell controllers.

you expect performance with a intregrated controller??????????

lol so true

I think he got several warnings about the SSD Defrag issue.

You hafta question the intelligence of a being that needs more than one warning about the same thing.

Oh no I'm pretty sure we won't get the exact same problem again, but then there's an infinite amount of stuff that can go wrong.. why pick the same thing twice?

But I'm almost 59. It's not my turn to watch him anymore.

I see always the youth that has to take the blame.. for some other youths idiotic behavior - ok that's probably fair :/

I hope the OP sees this. I have a 2 TB green drive (Samsung EcoGreen F3) and I was having horrible waits on the drive (using it as video storage for my DVR). I was able to download Samsung's tool and change the AAM setting from "disabled" to "fast". It made a huge performance improvement.

Initially, I would have thought having AAM disabled (the default state) would have been better, but at least for my drive, changing it to fast was the ticket. I suggest downloading the tool for your drive, and try changing the AAM setting.

green drives should be used strictly for backup and storage purposes only (and really excel best as storage for large media files, I'll still use faster drives to do backups) as they still have excellent sustained transfer speeds - 80-120MB/s IME

you're pretty much a fool if you bought a whole bunch because of how cheap they are and expected to use them like any other 7200RPM drive

I use my green drive for everything, they are fast enough for me. Like i said i had wd re drives raid5 and there was nothing special about them but the price. Black drive as super fast but the heat and power is something i dont want to deal with. Having 10 WD 2TB Black, would be super fast. with my green raid5 I get about 300M/s that is great for me and i haven't finished building the array yet. So it will get even faster when i'm done.
Right now i'm having a problem with the SSD raid0, one of the drives is running in sata150 and not 300, i'm not sure how to fix it. I can reboot and that will fix it temp tho

Hello I am having some problems and i'm not sure if it the areca 1880ix-16 or my hard drives, SSD. When using Atto benchmark My write speed is much faster than my read speed. Atto seem to have a problem with the my 2 WD Black 1tb in raid0 or single. The read speed stalls or crash and it get a low score. Is there a way to post screen shots of the atto bench?

I use a WD Green 1TB drive as the primary drive in my HTPC.

Greens work perfectly for what i buy them for: storage.

They aren't the fastest, & i wouldn't be getting them for running programs or games, but they are cheap, & work great for multimedia storage for me.
