nice looks spot on for 4x32GB OCZ SSD Core on onboard intel controller

Great start I see My 4x32 GB Ocz Core Series Raid 0

Will be interesting to see how using a hardware raid controller with 256MB DDR2 cache would do for my set of OCZ SSD Core disks

Highpoint RocketRaid 3520LF + 4x32GB OCZ SSD Core V1 Raid 0

Update: Had to get some of the awesome numbers out there, so here's a preview for ATTO Bench 256MB length and HDTach 32MB with 4x32GB OCZ SSD Core V1 raid 0 in various controller block size configurations.

ATTO Bench 256MB
256K Block size saw ATTO pull out well over 500+ MB/s read and 300+ MB/s write

16K Block size vs 64K Block size

128K Block size vs 256K Block size

HDTach 32MB
Again 256K Block size led the way with 482.8MB/s average read speed and 1002MB/s burst speeds

16K Block size vs 64K Block size

128K Block size vs 256K Block size

That is so wierd When I use HD tach all I get is 118 MB/s. It's so wierd but when I use hdtune 450 mb/s even everest got 454 MB/s. No bench like that in HDtach

New thread full of results for hardware raid controller -> OCZ Core SSD 2.5" solid state disk Raid - Highpoint RocketRaid 3520LF PCI-E x8 Raid controller

Hi,
I'm planning on upgrading my computer with this type of setup but have a few questions that perhaps you can help me with. I do a little gaming, lot's of web browsing/downloading and some video decoding/encoding. I'm not looking to build the worlds fastest computer but I am looking for an improvement on my bootup time and general performance. So here is what I would like to know...

1. How did you connect the 2.5" SSD disks into a dekstop PC. I think you used MANHATTAN to do this but I can't seem to find a place that sells them.

2. I'm planning on buying 2 x 64GB OCZ SSD v2 drives and putting them in RAID0 with the ASUS motherboards built-in RAID controller. I'm sure this will not give me the performance you show in your tests but will I still get a significant gain as opposed to using 2 x 500gb Seagate 7200rpm disks?

3. Are there any lower-end raid controller cards that you would recommend instead of using the on board controller?

4. I will also be putting a 1TB SATA2 Seagate 7200 RPM disk for storage. Will this slow my SSD raid config or cause any issues on my system? Also, would it be a good idea to put my pagefile on the 1TB storage or am I better of completely disabling it?

Any response would be greatly appreciated.

Hi Slicster,

Best to do some research and read stickies on OCZ forums to be aware of possible issues http://www.ocztechnologyforum.com/fo...play.php?f=186. I haven't experienced these issues as I have custom nlite/vlite made WinXP Pro SP2/SP3, Vista Ultimate SP1 32bit and 64bit install cds with latest hotfix updates integrated as well. You can see my nLite/vLite custom build sticky threads in Operating system forum here http://i4memory.com/f78/

1. I connected them using either manhattan dual 2.5" drive racks or just by themselves since I don't use pc cases - haven't used a pc case in several years for my everyday and benching rigs. Except in case of my HTPC build

2. There are gains to be made, but also some limitations in terms of write speeds so that's where a dedicated hardware PCI-E raid controller with memory cache will improve things beyond regular drive raid.

3. Highpoint RocketRaid 3510LF and 3520LF, and 3120LF are SSD friendly. There's also Adaptec 2405, 5405, 5805 PCI-E controllers too. Pay attention to their PCI-E bus link bandwidth requirements - i.e. 3520LF needs x8 PCI-E slot to run full speed, while some lower class raid controllers may get away with x1 or x4 PCI-E requirements.

4. I've never had much luck when it comes to regular hdds with some raided and some non-raided when it comes to onboard ICH9R/ICH10R controllers and matrix raid. I prefer to separate raid to dedicated hardware raid controller and leave onboard controller for non-raid drives. For me I need raid to be portable from system to system in case of motherboard failure.

If you OCZ forum link i provided their stickies suggest a workaround to placing pagefile on regular drive and have info showing you how to do it. I never used any of those tips/work arounds as I never had any problems from day one on ICH10R or on Highpoint 3520LF.

While I benchmarked OS related ssd results, the main purpose of me getting SSD was for non-OS usage as a scratch disk/video encoding work array. I got 3520LF PCI-E as an intended replacement for my new 24/7 main/work pc as my current main pc runs 8x SATA disks on 2x raid 5 arrays with Raidcore BC4852 PCI-X raid controller. New rig will have 4x640GB Samsung HD642JJ + 4x1TB Samsung HD103UJ disks on 3520LF PCI-E (might get a 2nd 3520LF PCI-E for SSD disks or grab Highpoint's flag ship Rocketraid 4320 PCI-E SAS/SATA raid controller!)
