post #11 of 24


Intel 510 SSD against 2 RAID 0 caviar greens.
Reeedoncolous.

Thats what I have on my rig, the caviar greens are slowmonsters but lownoise and heathefficient.

As much as I love SSDs, they're just not worth it at this point in time to me. There are other options out there, but you're still not gonna get SSD performance.

You can buy a pair of WD VelociRaptor 10K RPM drives and put them in RAID 0. The performance will be slower than high end SSD, but you should be able to keep up with mid range ones. Most importantly, you'll have much more storage.

Another option would be the Seagate Momentus XT, it's a SSD/HDD hybrid drive and beats a single WD VelociRaptor.

It's so much cheaper though. Why don't more people use it?

Because A. It's not much cheaper (a 150gb Velociraptor is 120-150 dollars, a 120-128gb SSD is 180-200 dollars) and B. It's still not *nearly* as fast. (a 5-7ms seek time versus a 0.1ms seek time, with just as good-if-not-better sequential performance on the SSD as well.)

Despite what iKhan says, a RAID array of 2 velociraptors will not keep up with even a low end SSD. You can RAID as many of them as you want - you'll never get into sub-1ms seek times.

SSDs have super fast access times, very high IOPS, and in general make PCs highly responsive. Most new SSDs average over 200MB/sec for most tasks.

HDDs, though... most of them average over 20MB/sec for most tasks. (excluding stuff like file copying, where they perform at nearly their sequential speeds) RAID can nearly double that, but you're still a long way off from a SSD - and you'll never get much past the IOPS limit of regular desktop drives. (80-120 IOPS, generally - SSDs are usually well over 8,000)

Now I myself have.... 500GB of Steam games (installed - I have more not downloaded), ~100GB of pictures, ~100GB of projects, ~20GB of business stuff, ~800GB of home videos, etc. etc.

I've probably got about 5TB of space in use for my own stuff (inc backups), and then there's all the space used by stuff that is against the TOS of these forums.

Do you know how much money I'd have to spend on an SSD to accelerate all that? For me RAID is the answer. But if you can fit what you've got onto an affordable SSD, definitely go that path.
I'm the oddball then. I have 4.06TB of storage and currently a little over 2.5tb is being used. I have 400gb of games alone (damn steam sales). LOL

All these options depend on budget, Never never ever RAID 0 more than 2 mechanical drives unless you don't care about your data, one failure means nothing is recoverable,
The Drive setup I am looking at is one 120gb SSD, and 4 RAID 5 1tb F3s for storage, then one drive can fail and you loose nothing and you can go put in another one and rebuild the redundancy

Personally, I have my main desktop with one single 64GB SSD in it. It's way too much for my general use as I don't game. It's got about 4GB's used, and I have never used more than 6GB's at a time. All of my data resides on my server, which I'm about to upgrade and have 12 TB's for my stuff.

It really depends on how many games and programs/operating systems you have. My one gentoo install with a 2GB ramdisk is really tiny. All of my videos and personal files are all remotely accessed on my server, so I have no reason not to use an SSD now. Besides, 7 second boots (really slow actually for gentoo on an SSD) is good enough for me.

TLDR:
All depends on your uses, client/server architectural, you may as well go with an SSD.

I assume you mean 4GB used excluding windows?

VelociRaptor in RAID0 will give you around 1.5MB/s in random performance for $200-300.

A 60GB will give you 50-80MB/s in random performance for $100.

VelociRaptor are no where even close to even low-end SSDs.

Seagate Momentus XT performance benefits are usage specific. There is only a 4GB NAND read-cache.

I know SSDs are a bit expensive, but I think I may be in the range for somewhere around an 80GB drive.

Thanks again!
Careful, once you go SSD, you won't want to go back I bought my first SSD right when Win7 was released, and I've since bought two more for my desktop and one for my laptop...
