  1. Thanks for confirming my suspicions about RAID and trim. I assume similar problem with TRIM and JBOD or BIG on the Convoy box as it would be the controller there that permits multiple SATA drives through single eSATA port. Previously I had found that multiport SATA not available on P7P55-m mobo. To be sure I am not misusing the terminology, there is no eSATA port on mobo, just have after-market bracket with eSATA port that runs cable to internal SATA on mobo. I have been assuming that is correctly referred to as eSATA as a port and cable to the Convoy box/case. Thus it would seem the chipset involved, copied from the mobo specs at ASUS site is as follows: Intel® P55 Express Chipset built-in 6 xSATA 3.0 Gb/s ports Intel Matrix Storage Technology Support RAID 0,1,0+1,5,10 VIA VT6415 PATA controller 1 x UltraDMA 133/100/66 The Convoy XL specs don't seem to indicate what controller/hardware it uses. Does this help?
  2. To clarify, one major concern is availability of TRIM or whether I will rely on the garbage collection and run at 80% capacity. I figure its No TRIM with RAID but not sure if TRIM is still possible with controller running in JBOD or BIG mode. And I frankly don't have a good grasp of how garbage collection would work in any of the possible modes. So this is really about SSDs rather than just a RAID question. TIA, Croc
  3. Ooops. Forgot the question before the posting went out! Rusty forum manners. Sorry. I want to set up the SSDs in the Convoy box to get a fast backup roughly 1 TB, redundant to other storage, hooked via the ESATA. Choices on the Convoy include RAID O, 1, JBOD, and BIG/spanned. Thoughts, suggestions appreciated as I am a total newby at RAID or spanned drives. The mobo doesn't have multiport for the SATA or room to add a multiport card, thus the Convoy box idea. Thanks Croc
  4. I have a home Windows 7 rig with Intel G2 x-25m ssd + Samsung HDD internal on ASUS P7P55-M mobo (SATA2 3GBS). I have both an external drive enclosure with HDD on ESATA and an NAS with HDD for various photo backups, music and other shares. I have never messed much with RAID. I back stuff up manually and scheduled automatically with True Image due to well-earned hardware & disaster paranoia. I inherited a Patriot Convoy PCXL25SR external enclosure for 2x 2.5" HDD or SSD SATA2 drives, ESATA capability as well as a selection of RAID 1, 0, JBOD & BIG/spanned options. I have an unused ESATA port on a back bracket. Today a friend traded me 2 512GB Kingston V+100 SSDs (3GBS SATA2)for some old gear. :-)
  5. Ditto the question -- I am also in the market for some external enclosures -- preferably for 1 - 3 drives, ATA, or SCSI U320 [not mixed ].
  6. Can this be added ass a link in the Reference Guide section of Seems handy.

    Use 1 Scsi Channel Or 2?

    Thanks again - appreciate the confirmation.

    Use 1 Scsi Channel Or 2?

    Thanks -- does the split of channel A for O/S and B for other HDDs look right?
  9. I have a photoshop oriented XP system that is also used for general purposes and gaming, based on the ASUS P4C800E-DLX/PIV 3.06G CPU with lots of RAM. I have some fast SCSI drives to use and the only controller card at my disposal is an Adaptec 39320R -- which is rather more than I expect I need. In connecting drives to the card I am receiving conflicting advice: one person tells me I must use both channels for optimum performance and another says that is potentially harming performance. I have 3 15K.3 Cheetah drives in addition to some SATA storage drives. I am not interested in RAID 0 but at some point might consider RAID 1 for images storage. The drives are 18G [O/S and Apps], 36G[paging and worktable] and 73G [on-hand image files and games]. One proponent says leave the O/S drive on channel A and put the others on B to avoid potential conflicts; the others say put them all on A to avoid unnecessary delays. While I have used SCSI rigs for several years now, I am not knowledgable at all on dual-channel SCSI cards [other than those with separate Ultra SCSI and 50-pin channels]. Of course, the 39320R has 2 LVD ultra 320 channels though they are both effectively limited to lower speeds with the PCI bus [not 64, only 32 -- sigh]. Any ideas? Does it even matter in any way, shape or form? Thanks.
  10. Followiing this thread is more fun than surfing reruns on Discovery channel!
  11. I would be most curious regarding performance of the 15k.3 HDDs with this mobo, as there has been much argument/discussion as to what the PCI bus speed is for the scsi controller -- obviously that could have a major difference. I am not interested in using SCSI hardware RAID with the board, just to run my 15k.3s independently. AnandTech has article claiming this is 66mb/s bus but others say 33... Any actual performance reports would be great!

    U320 vs U160

    Actually, putting aside "need" vs "what I have", I'd like to get further answers along the same line. I have [and certainly don't necessarily need to have] an Adaptec U160 card on 32bit/33mhz pci bus desktop board using XP. In a garage sale last month I managed to purchase -- for next to nothing -- 2 new-in-the-box Cheetah 15k.3 drives, U320 18G and 36G. I had previously used old 10K and newer 10K3 U160 Quantum/Maxtor drives for o/s, apps, games and photoshop/photoimage 'desktop", but took the opportunity to give those 10k HDDs to someone who actually needs scsi for a volunteer organization's server. Data and image storage go on plain vanilla large capacity 7200 and 5400 rpm IDE drives. I am getting ready to migrate from tried and true CUSL-2 to newer P4 based board but want to keep my new and very reliable scsi HDDs. I don't expect to go to anything other than another 32bit/33mhz pci type board at this point-- can't justify expense. I also use my system for gaming, but that hardly stresses the HDDs. How much of a hit might I be taking by using the 2 U320 drives on the single-LVD-channel Adaptec 19160 card? Given my usage, I figure that it isn't much practical impact but I also know that I could use some expert advice. Is ther any reasonable step I can take to better utilize the HDDs? My brother is a webpage designer and has already given me the appropriate you-don't-deserve-to-or-need-to-have-15k.3 speech so you can skip that part, please. Thanks.
  13. Ahhh -- that makes sense! Thanks very much for the pointer, cesmadj. The work systems are nearly all older non-LVD non-U160/U320 HDDs and I frankly don't know what their termination requirements are. I believe one of the previously installed drives has TP enabled even though it's U160 and is actively terminated at the end of the cable. Does that pose a potential problem such that I should pull the drives to check and disable TP? TIA
  14. bump -- need some expert advice here!
  15. I am adding a 36G Cheetah 15k3 to my Adaptec 19160 LVD bus on my photoshop rig at home. Seagate brochure says termination power [pin 1 on J2] is off by default setting -- no jumper. I already have 3 drives on the bus -- I'm replacing the Atlas 10K that is suddenly getting noisy. As you can likely guess, I had the enviable luck of getting a very nice HDD for nearly free, even though it exceeds my needs [there is another 18G 15K3 already hooked up - same source and same cost]. Is there a downside to enabling termination power? I believe it is enabled already on at least one of the drives -- but I didn't do the last install and haven't checked. At work I have heard that SOP is to enable Termination Power on all drives, IIRC, to eliminate potential installation goofs. Is that a bad idea? Is there good reason to only enable TP when it is not otherwise available? I believe the new drive will end up as last drive on the cable. I don't know whether the 19160 provides power to the cable itself. Thanks for any ideas or hints.
