    Poor Mans Raid and Disk Tips

    I finally got around to revising article, noe that HDD prices are finally coming back down some. Some corrections accuracy enhancements were made in response to Continumm inputs. Much of the Idle speculation was removed. ATTO benchmark is now mentioned, but not shown. I now clarify the W7 is friendly to the SSD hardware. It's still a problem if you need to relocate folders and files to the HDD. There is a new utility out called Steam Mover which was made to move game folders and leave a link. Some swear by it and say it works for a lot of W7 folders. I have not used it, and I'm not sure how badly I could botch thing up. "I would be curious if AMD chipset RAID does interleave reads or whatnot. Again, it's a blanket statement you've made that I would want to verify is correct before making it. (and yeah, I don't see much in the way of reviews on Google on chipset-level RAID...)" CrystalDisk mark shows a normal 133MB/s for large sequential reads with raid 1. IO meter showed 220MB/s with 2 workers for 10M seq. read. Frankly I'm feed up with the marketing types hiding hard engineering data these days. Maybe they deserve and need more blanket statements, slander, and inuendo. About GPT and large LBA's. I really do want to punt this issue. It's enough that I warn people about this potential issue. There is plenty of good help out there on many different forums.
  3. Experiments with my ASUS P8P67 deluxe showed the Intel Chip Set SATA to be all RAID or no RAID with no mixing. My 2nd (Marvel) SATA did not support boot drives, which made placing the SSD boot drive troublesome. Win7-64 has a good software Raid 0, so it helped by letting both SSD and Raid work on Intel Chip Set SATA. A 3rd on board SATA controller provides my ESATA. Also note that PCI ESATA cards are reasonably priced. ESATA is a removable drive type and also has higher signal voltages to make up for line loss. To run it as raid directly from your controller invites drive drop out and data loss. Many external multibay enclosures can do raid.
  4. I was looking for something like this: Silverstone 60mm + 43mm + 43mm + 43mm Four-in-one SATA Power Connectors with Power Stabilizing Capacitors Model CP06 http://www.newegg.com/Product/Product.aspx?Item=N82E16812162011 It's a shame I don't have the OCZ Agility3 BSOD drive anymore.

    Poor Mans Raid and Disk Tips

    Post 3 - You have a point. I wanted to point them to what is likely a better option. I did not want to discuss PCI vs PCIe vs PCIe 2.0 or x1 serial channels vs. x4 serial channels, or serial protocol overhead, or RAID card vendors stating the actual x1 BW. I did want to point them to what is likely a better option. Post 4 - Yea, I have tried several time to get it NCQ function. Set bios to AHCI and loaded the latest drivers. Surfed the web for details. If I missed something, it's because it's hidden, and it shouldn't be. This Gigabyte SATA controller also supports floppy,PATA, and the driver has a check box for Tagged Command Queueing. XP OS. The performance seems low and I don't need it. Post 5 - I have been reading more about Windows Cache Manager. It's tough to get the details. Most hard documentation originated with Win 2K. I was led astray by some older caching utilies that reported my file cache as 100MB, but of course they did not function or reload on restart. Small test files do have issues with cache distorting results. It seems the cache to concerned with is in the HDD. Most benchmarks can and shouuld bypass Windows file cache. FancyCache is a utility that uses a different cache method, strategy, whatever, they have a web site. Post 6 - OK, I'm not sure where I read or drew that conclusion that from. The larger M4 SSD have higher sequential writes. Other brands / models tend to folow this trend. Block Alignment - My C: to D: was put out of alignment by using ESUS, my favorite partioning program. It heard of the issue to late and don't care to do a clean install. I tried the command prompt queries and the calculate, and tried moving the partition boundries several times. There is software I can buy, but I can also ignore a tiny bit of unallocated space. Relocating user folders was easy in XP. I did spend hours searching for W7 tips. These tips are work arounds, and suggest or require a clean install. I'm complaining about it, but not hurting with a 256GB SSD. The people using 60GB or less should know they could have issues. Post 7 - This is Poor Mans Raid and we use what we have on the motherboard. I'm sure there are RAID 1 controllers that interleave reads for a price. Post 9 - Good point. RAID 5 and RAID 6 capacity loss should be corrected. I had 4 drives to work with.. and did not think beyond that. I only touched on RAID 5 and 10 as they were supported motherboard bios options. Anyway, I made a case for only using two consumer drives. Anything more that that is out of the poor mans budget. Post 11 - My side step is quick, easy, and low risk. I did not want to bother with registry changes. Tom's Hardware has a sticky with instructions. I saw a link to OCZ fourms for instructions. Post 12 - It was beyond the scope. I don't have all the GPT details or a 3TB drive to test with. I'm sure there is plenty of info out there.

    Intel P67 South Bridge SATA with one SSD and HDD RAID. Changing SATA drivers on XP boot drive.

    Drives for a RAID setup

    Check out the RAID 50 poll. If it modifies a stripe (edit file) it also has to rewrite the parity stripe. It has to read/modify/write. You're better off with RAID 0 for write speed.

    The other posters have a point. 7200 RPM should be fast enough. RAID 0 is plenty fast enough. RAID 5 does have parity calculation overhead. No issue for a good 4 core CPU. Your motherboards South Bridge should handle it just fine. Don't use the Mo'bos 2nd SATA controller. Maybe it doesn't have enough write cache. Maybe it's PCIE x1 channel and write is low priority. It just benchmarks poorly. If your nervous try changing your OS disk cache sizes. There are methods and programs. FancyCache is a good 30 day trial.
