  1. To Stamatis and everyone I recently installed a Vertex II 180 on my P55 board (ECS P55H-A) and its not performing any much better than the G.Skill Falcon 64 i had from 2009. In fact neither exceed 180 at the best of cases... So it wasn't the Falcon's fault for such low numbers as i thought. It was only just a few days ago that i thought if maybe there's an issue with P55 chipsets and SSDs and so i stumbled on few resources like this here. Disabling all power saving options it only added about 10 mb/s more .... ( Is there a chance the sata cables are sata 1 or something? i think theres no such limitation, all sata cables allow any tranfer rate ?) Any ideas ?

    some SSD questions

    1. i would be interested also in opinions / experiences / knowledge on the trim value . I am concerned about as i got recently this : http://i250.photobucket.com/albums/gg246/monographix/PC%20related/as-ssd-benchGSKILLFALCON66420111-23-09.png after a year of usage. When i first installed the OS (7) on it, benchs were normal. I didnt bother since then running a bench again or do any wiper style maintenance ... 2. Drive is a G.Skill Falcon 64 (dont recall the OCZ equivalent) i think its an indilinx and its firmware 1571 (1.3 ocz i think) was supposedly supporting windows trim. Their forum suppport although responsive i have been always had issues with their communication skills (or interest to invest on proper communication lol)

    some SSD questions

    1. Does Windows 7 pass trim commands to EVERY SSD on the system or just ONLY the SSD where its installed on ? There might be other SSD drives in the system, either containing other OSes (XP, linux etc) or just data (applications for example, or large work files), will those SSD drive be "trimed" by the 7 ? 2. is the use of "wiper" (indilinx SSD) dependented to the Firmware? for example could be damaging or not working with some firmwares? Thank you

    i have changed the raid configuration to a single array / single volume. NTFS allocation unit (cluster size) = "default" (4k?) Stripe size = 128 same performance .... 100-130 mb/s ... i will now bench a single raptor on its own ....

    Does anything have to do maybe with the IDE drive being on the ICHR as well? (on AHCI mode i guess) You mean you have the 4 150s on a raid-0 and the 4 74s on a Raid-0?

    Thanks for replying b]1.[/b] Board is Gigabyte DS4 2. Strip size = 128, Allocation Unit Size = dont know yet, tried acronis and PQ/Norton Partition magic info, couldnt find the allocation size i tried both on and off write back cache but still although improved after write back cache the HDtach shows lower performance than it should 3. someone told me that taking advantage of the ICH9R option to create two volumes in the same array would speed up the access time in a small volume of that kind (having it looking in a small area of 4x10gigs in the case of a 40gb volume i made in my case for swap files). Same settings in both arrays? as far as i remember yes didnt change anything except capacities (and the second volume has two partitions) stripe size, write cache, all same. 4. I meant opening files from the raid and saving again to the raid and then comparing with the open/save performance of the single sata IDE drive HDtach report without write cache : http://www.pctechnology.gr/vbull/vb/attach...mp;d=1197397238 HDtach report with write cache enabled http://www.pctechnology.gr/vbull/vb/attach...mp;d=1197452733
  8. 1. P35 mainboard ICH9R controller 2. 4x Raptors 150 3. 1x WD 750 5. all 5 HDD on ICH9R 6. 8 GB Ram 7. XP x64 Pro 8. C2D E6850 this workstation will be used for graphic design, priority is performance under DTP applications as Photoshop and CorelDRAW, opening big files with many pages including lots of effects and very high resolution images and on the fly image editing etc. Those applications create a scratch file no matter how much ram there is and they make heavy use of that scratch file. for example a 500mb psd file while working on it creates a 6.5 Gb scratch (also called swap) file in three minutes, the more you work on it the bigger it becomes ...... And another critical point is the saving/writing and opening/reading speed of those big files ...... Photoshop also is incapable of seeing more than 3gb ram So, i thought after consideration of various schemes to set it up like this: 1. 4xRaptors 150 in a single Raid-0 volume of two "virtual" arrays, one of 40 Gb for the scratch files and the rest storage space for the work files 2. OS, Program files and first stage backup/synchro of the work files in the 750 sata IDE 3. make a ramdisk of 4-6 gb ram for applications to save as first priority their scratch file (when full, save then to the 40gb raid virtual array) any better ideas maybe? What i am sceptical about with this scheme, as every scheme had its drawback, is that scratch file and work files will be on the same physical drive, the single 4disk Raid-0 array. Now what puzzles is that, I did a test with Photoshop opening a 500mb file (using ramdisk as scratch file saving area) and saving from/in the raid array and from/in the single IDE sata drive and i didnt feel or measured a speed difference ..... whats the deal with this ? ...... Any input appreciated Thanks

    SATA / Raptor newbie questions

    Really, i am finding now people claim that this 36g Raptor isnt practicaly, in average RL conditions, faster than any 7200 16mb cache SATA2 driver .... ( i wish was told that before so i would had investigate it) If thats true indeed, i am seriously tempted to replace it with another RE 2500YS ... Any input here maybe? Thanks

    SATA / Raptor newbie questions

    Also, Now besides the constant HDD activity, Windows also freeze occasionaly (and the raptor activity stops while windows are frozen) for a while and then resume ...
  11. I have just installed my first ever SATA drives. I copied my windows partition from my previous 80GB maxtor PATA 133 (dmax9) to a 36.7 WD ADFD Raptor and added also to my system a SATA2 WD 2500YS. i am currently running them in AHCI mode. I dont itend to make any RAID arrays not in this PC at least. Any gains maybe from having the SATA drives in any of these modes: "non-RAID" ( i guess IDE emulation?) / RAID / AHCI ? i havent seen yet a feelable performance increase. I am told afterwards unfortunately that the performance of the 36.7 raptor isnt any better than any 7200 sata2 drive with 16mb cache ... how true could that be? this Raptor appears for some reason under some constant access activity. its doing this subtle short scratchy noise like every second while idle. Windows Indexing service is disabled as NTFS LastAccess feature too. i kept internaly one of my previous PATA 133 drives. Is there a possibility that for some reason the existence of an IDE drive would hinder somehow the performance of the SATA ones? Thanks notes: - Raptors are indeed NOISY .... remind me the sound of ancient 2Gb quantum fireballs - Sata cable connectors and WD drives SATA connectors are so delicate ... so easy to either get disconnected or break ... Some hot plug feature (AHCI/RAID?) would protect the drive and data in such incidents?
