Finally pulling trigger on SSDs; Better to have single OCZ Agility 3 240GB(Tier 4 performance) or 2x Raid 0 OCZ Agility 3 120gb (Tier 8)

post #1 of 29
Thread Starter 
As title states, I am looking to embark on my first journey into SSD land. My motherboard is the Asus P8Z68 V-Pro with 6gb/s and after an afternoon of number crunching, the two driives listed end up topping my price/performance chart.

If you are wondering where I got the tiers, its from Tom's Hardware's January 2012 best SSD's for the money

TLDR about tiers: tom's says that the difference in performance between each sequential tier is 10% This means that the difference generally between the 240GB and 120GB OCZ Agility 3's is approximately 35% in favor of the 240gb.

They ranked the SSDs in order of best to lowest performance. My question is whether its better to buy a single 240gb higher performance(Tier 4) SSD for $270 ($1.12/gb) or split my drives into two lower performance Tier 8 OCZ Agility 3's at 120gb each for $290 total ($1.20/gb).

I have never done a Raid 0 SSD setup before. I want to get the most out of my equipment but not hamper myself for future potential upgrades. E.g., 240GB Agility 3 may be much cheaper in 6 months, might want to raid 0 that for incredible awesomeness.

What is your preference? I will likely be just using the on-board Raid 0 functions of my motherboard (rather than a separate controller). Typical usage is gaming/benchmarking (naturally).

Ignore Tom's "Tiers"....... You will not notice a performance difference doing common tasks... just get the cheapest SSD using the current generation controller.


RAID0 SSD will generally not provide you any benefit unless you are reading/writing GBs of data to memory.... or have another storage array capable of 500MB/s+.

IMO and from experience it would be best to buy a single 240GB drive. In fact I just bought a 240GB Agility 3 recently.

If you're on SATA 3, the speed difference from a single to RAID is not going to be worth anything real-world. A single 240 will be more useful long-term, and half the failure chance vs RAID 0.

I also bought mine figuring that since it's a popular drive, I can RAID it with another if/when they go on sale and have a 420GB drive, which would be nice just for the size, not thinking of speed benefit.

I have bought quite a few SSDs, and splitting data up between drives gets tiring. Buy the biggest single drive you can afford.

agility NOTHING..i fully expect this agility2 to crap out at any moment..and have $$ put aside for that..
2 crucial m4 64gb in raid 0
or..since you're looking @ RAID 0 and the $300 mark..

3 crucial m4s
or 4 of these
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233188

raid 0 does read/write faster with ssd ....fastest read/writing i've ever experienced was with 2 agility 2s in raid 0
unfortunately..they only lasted about 3 mos

Read this article and you'll see why the Vertex 3 is a much better choice than Agility if you have to go Sandforce based drive.

gonna have to be a 120GB Corsair Force GT

Any suggestions as to what to install on my SSD and what else to leave for the big hard drives? I mean, besides OS, obviously. I use steam for almost all of my games, so perhaps my steam folder?

At which point does the drive become too saturated with crap and start to lose performance?

RAID0 only improves SEQUENTIAL read/writes..... these are unimportant in most cases. How often do you load a 2GB file into memory? How often do you read/write to another storage device capable of 600+ MB/s?

From what i know, you cannot have Trim in raid. Please coreect me if i am wrong. Based on that it would be better to get 1 drive rater than 2 in RAID.
