Intel SSD. 2x80GB RAID0 vs 1x160GB [Archive]

so from the specs listed, intel has capped the write speed on the 80GB to 70mbps, whereas the 160 GB has up to 100mbps.

now my question is simple, what will give better overall performance. 1x160, or 2 80s in RAID0? i want to say the raid config will be better, but i wanted to ask the experts.

also, how is TRIM affected when you put these drives in RAID? or does it not matter at all?

Since most users are reading from the disk more than writing to it, I'd recommend going with two 80GB. I wish I had.. To my knowledge, intel hasn't released TRIM for their SSDs. I know they did, but it was pulled. Maybe it was re-released?

Is there any way to TRIM 2x80gb in RAID 0?

for SSD, single 160GB drive is a better buy

I think you can still do them both with the .iso image. It flashes via bootable disk - It looked for any other SSDs after it flashed my first one, so I think it would work. I did get a warning screen noting that I MIGHT lose data, but it went fine - no losses.

really?? why is that?

A single 160 GB is a better buy than two 80GBs in RAID 0 because no RAID controller supports forwarding the TRIM command. Although they did mention on the PC Perspective podcast Areca was planning to add TRIM support at some point in the future.

In the meantime you can always do the "tony-trim" once a week until RAID0 trim is implemented.

I also had this question. I'll probably be getting an SSD in the near future and was deciding between 2x80GB in RAID0 or the 160GB. I think I'll prefer the single SSD setup (due to TRIM support and my wariness toward RAID).

It would be nice to see some performance benchmarks comparing the two.

2 In raid 0 is the way to go, use perfect disk 10 to consolidate free space and your golden.

0 performance loss over 6 months an I have mine at over 90% capacity!

Benchmarks will show double the numbers using raid0.
however, and this is crucial and important, one drive is as good for practical use, meaning, if your habits are not anything special using the computer, you wont notice any difference between a raid0 or a single disk using ssd.

Since the price/in stock is slow and nill here, I got 2 40gb Kingston ssd and run them in raid0 allowing me to get the performance of a single drive writes and a tad better reads, 350/80.
But I wouldnt notice any difference between my setup and a single 80gb drive.

Computer is fast as hell anyway ;)

If going single drive only, I wouldn't recommend going any smaller than a 64GB drive. My 80GB is about 60% full and I don't have much installed on my PC compared to a lot of people.

As far as I read from here, that TRIM does not work with RAIDED drives...

Really hmmm cool. I'll have to look into that myself when the performance starts to drop off. Im going on.. just over 2 months at about 50% capacity on my setup and noticable performance drops on the disks, even re-running benches they are within reason.
