Best slot for raid card

got a sata highpoint raid card coming
any advise on best pci slot for raid
im assuming 4 but what are you lot using

i have proven this time and time again to a many a people. i do not know why others have had this problem. i have had the sb live, usb, and the nic steering the same irq. not one single problem, audio hiccup (pops, cracks), nor problem with throughput. this was in win98 and me.
seriously, although i do agree in allocating in the order of priority. scsi, nics, soundcards, etc-thats my zen . if you get my point. although i have seen good credible people i know that handle hardware correctly and they have had a minor problem with a p.o.s. periph, but they noted usually fixed with a new driver. sound blasters work well, contrary what many have said, steering irq's with another periph-i have done it for years, literally. this is also with systems i have built for my friends and family.
agp1, pci1, pci2, pci3 unless there are integrated features for the motherboard always have their own interrupt lines. obviously though if you are going to use agp1 you are not going to want to use pci1 if you dont want to steer the interrupt. pci4, 5, 6 always have a duped interrupt line like agp1 and pci1.
it really doesnt matter. specially with an os that will allow the usage of the apic. if that was the case then there would be a lot of servers in this world that are more fu**ed up than you think.

Best Slot for sound card

Hello.I have a simple question about my sound card.
I have Msi Z97 gaming 5 and Creative sound blaster z.My graphic card is N660 Gaming 2GD5/OC. I was wonder what is best PCI-X slot to add the card.
In the upper place or down?

personally I would use the upper x1 slot so the heat off the sound card isn't being pulled into the Graphics cards cooler increasing its temperature a little but that's just me.

I would like to connect my Ipad 2 wirelessly via 3G with a wireless rooter. The Ipad does not have a slot for a card, so it will have to connect to the rooter via bluetooth. Is this possible?

I would like to connect my Ipad 2 wirelessly via 3G with a wireless rooter. The Ipad does not have a slot for a card, so it will have to connect to the rooter via bluetooth. Is this possible? If so, where can I buy such a rooter? Many thanks! Ina

I'm not really understanding what you want. You mention all 3 types of connections: wireless, 3G and bluetooth, but I'm not clear on what you want to do. What the router is supposed to do, and why do you think it would need to connect via bluetooth?
I'm thinking you want to buy a Mifi type device that will allow you to connect to a cellular network and then connect the iPad to that device via the Wifi network the Mifi produces.
Is that so?

Best slot for new PCIe FW-expansion card

Hi there,
I just upgraded my PM Quad with a NVIDIA 7800 GTX 512 card which occupies PCIe slots 1 and 2.
Now I will have to install a FW 400/800 expansion card for operation of an external audio interface. I know that slot 3 would probably offer the best performance for the next card to be installed (8-lane)- but is likely to obstruct proper air circulation for the fan of my graphics card.
So slot 4 (4-lane) would be the only alternative. I cannot judge if this would be sufficient for proper audio performance.
So, any comments from the audience?
Regards,
Oliver

Great - glad to hear that.
Just inserted my card into slot 4 - real plug 'n play - smooth operation - no complaints so far!

Best Throughput for RAID - Internal SATA vs. PCI RAID Card

Hi, we're upgrading our old server, which has been on an upgraded G4. We put 3 SATA drives in it, connected to a Highpoint 1820a RAID card running RAID 5.
We're moving this to an older G5 1.6 GHz model (2003). It currently has 2 internal SATA drive bays, but I know can be expanded with an adapter kit. It also has just plain PCI slots (not PCI-X or PCIe).
So I'm wondering what would provide better performance (throughput I guess):
• Using the 2 internal bays with a software RAID 1?
• Putting our old Highpoint RAID card in the PCI slot and running RAID 1 or possibly RAID 5 (with another drive)?
I know the RAID card doesn't use the processor for RAID functions, but I think in a RAID 1 it's fairly minimal, correct? I'm mostly wondering if the older basic PCI slot would bet the bottleneck in a fast system compared to the onboard SATA controllers?
THANKS!

Well, we're most concerned with data security and reliability. We're not streaming video or anything else that would demand extreme throughput. The server is mostly serving files to 4-5 users. So I imagine the performance gains would only be noticed when opening/closing files off the server, correct?
And we already own the Highpoint card, which has 8 internal SATA ports, so we'll probably use this. It works fine on PCI bus. So we can run this with 4 drives in either two RAID 1s (boot & files); a RAID 5, or a RAID 10.
We'll probably stick with Western Digital or Seagate 'enterprise' SATA drives, such as the WD RE3.
So, do you think we would see much real-world difference between the different RAID options (RAID 1 software, RAID 1 hardware, RAID 5 hardware, RAID 10 hardware)?
Thanks!

Best option for RAID 5 with 4 drives?

I have been thinking about doing a RAID 5 setup with 4 1TB drives.
My motherboard has enough intel SATA ports to run one through its chipset, but I've heard that can be problematic and wont perform as well.
What would be the best budget option for a small RAID? Are there any affordable RAID cards out there that would fit my needs? I could probably part with $300 for a card. I'll get 4 WD RE4 drives for the raid.
I will have a backup of this data so that's not a problem.

Hi Paul,
Areca ARC-1320-8i seems like the best option - or a variation of it (like ARC-1320-4i4x) - as long as you get four internal ports. It's right around $300.
That said, some of my clients run Intel RST RAID5 on four drives for some time, and it actually performs well:
(Personally I think software and hybrid RAIDs are the future of RAID technology: much more flexible than hardware RAID; potentially faster as well given that they have access to all of computer resources rather than just a dedicated processor. The latest iteration of RST, for example, allow SSDs for caching of RAID volumes.)
For my personal system, I use a $200 CineRAID H458 box with four Hitachi Deskstars in RAID5, which is a very inexpensive option for an external RAID:
Sure, it's rather slow; fast enough for my purposes though, and is highly portable, unlike any config with an internal RAID controller.
If I need something seriously faster (yet on a budget), I'd use something like this:

Any ideas on the best Config for RAID-0 on the Precision M6800 using SSD's (and the mSATA slot)

Hi, I have an M6800 on order that has a single 500GB 7200RPM hard drive. I am going to upgrade the storage the day it arrives (removing the 500GB drive and not utilizing it at all). I plan on setting up an SSD RAID-0 array and want to take advantage of the mSATA slot if possible.
I thought of using the 2TB 2.5" Seagate/Samsung Momentus SpinPoint ST2000LM003 hard drive for storing unused vhd\vhdx files as well as video and photos, then using an SSD RAID array for the OS, Applications, Data and any active vhd's.
Is it possible to set up RAID-0 using the mSATA SSD slot and the primary internal hard drive slot?  I want to use those 2 drive connectors so I can still use the 2TB 2.4" regular notebook hard drive without removing the Blu-Ray Writer? I plan to write video to Blu-Ray discs that will be stored on the internal 2TB drive, so removing the optical drive is something I want to avoid.
As a general question, Is there any advantage to using RAID with SSD's, or would a single 1TB mSATA SSD in the mSATA slot be nearly as fast in real world use as a 2 disk SSD RAID? Would I have a noticibly quicker boot time and application load time if using SSD RAID? I know the speed test specs show large increase in performance, but will the computer really run a lot faster with 2 x 500GB SSD in RAID-0 as opposed to getting a single 1TB SSD card for the mSATA slot?
I was planning on getting the Samsung Evo 840 SSD 2.5" drive and the matching Evo 840 mSATA card. There is a Samsung 850 series drive, but it is only available in 2.5" (mSATA is not available in the 850 as far as I can tell).
Please suggest the best solution that is compatible with the M6800 or provide any information that might help.
Thanks

Hi Ential,
Thanks for the info, I thought my question would go unanswered forever. I posted the question in January, and I have since set up the computer. Below I will detail my research and the configurations of drives that I have used on my M6800 since the time I posted the question you answered. Perhaps the results of my research and testing might help you.
I originally I bought the same exact model SSD's that Dell sells with the computer thru their website;    the LiteOn 512GB drives (mSata & SATA), I configured them in RAID-0. The LiteOn drives are sold under the brand name Plextor, I found the proper model numbers by looking at the SSD drive firmware upgrade file from the Dell support website.
From what I understood, my RAID-0 drive consisting of the 2 LiteOn drives had impressive performance using the AS SSD benchmark program, I was getting performance scores over 1600 back in February.
I have since changed to the Samsung EVO 850 1TB drives and again created a RAID-0 drive, one SATA drive and one mSata drive totaling 2TB. This drive array is getting AS SSD performance scores over 1900. I contacted Samsung to get some advice on the configuration of the drives and I got some interesting advice that seemed to help a lot:
Samsung told me to leave 200GB of the drives (100GB each) unallocated when I partitioned the drives, this is generally referred to as "overprovisioning" (which you probably knew already).  I initially thought that overprovisioning could only be configured by the Samsung Magician software and a special process needed to take place to tell the firmware to utilize a specific amount of drive space for overprovisioninng.  The Samsung support agent told me that the Samsung SSD firmware (on both mSata and SSD) automatically uses any unallocated space as overprovisioned space (they are basically the same thing to the drive firmware) and it increases performance in a very noticible way when you have sustained use of the drive and/or durinng the time in between the TRIM process (garbage collection). The unallocated space is used by the firmware to write data to while blocks of data are awaiting internal wiping initiated by the TRIM process.
Since I have 200GB of unallocated space, I am able to have more sustained deletion and writing of data between TRIM/Garbage Collection runnninng than I would ever utilize without affecting the performance of the drive. Basically most SSD drives have performance decrease throughout the day until the TRIM process is completed by the drives firmware, so Samsung instructed me to leave at least 10% of the drive space unallocated to limit that problem. Smaller drives likely need a higher percentage of space unallocated as compared to larger drives since the daily amount of read/write operations is typically the same regardless of drive size.   The amount of space left unallocated/overprovisioned is based upon the amount of read/write operations done on any given drive, not based on the size of the drive itself. If you run drive intensive applications, you would then want to overprovision more GB of drive space, if you have light use of the drive then you can overprovision/unallocate less GB of drive space (all of the configuration info regarding overprovisioning and TRIM was given to me by a Samsung specialist over the telephone - I called their tech support phone number and got a storage specialist to talk to me).
I will look into the SATA version on the optical bay, I never thought about that with this computer. My prior computer was a Dell XPS 17 3D (L702X) notebook which had 2 internal 2.5" SATA, in which I installed an optical bay drive. On that specific computer the optical bay was technically an SATA 3, but due to design constraints it couldnt run at that speed since there was voltage leakage across some pathways in the chipset when the optical bay has read-write throughput that is typical of a hard drive (as opposed to much less data transfer typically seen on an optical drive).  The M6800 can be factory configured with an optical bay hard drive, so I suspect it can support one properly. The XPS 17 was not available with an optical bay drive as an OEM configuration from Dell, so it couldnt be expected to properly support one. The design issue with the voltage leak across the chipset pathways on the XPS 17 was known by Dell, but due to the low bandwidth of an optical drive, the problem never occured with any of the factory OEM configurations.
It is possible that the optical bay hard drive offered by Dell (the exact OEM Drive installed by Dell) could have an internal limitation to SATA 2 due to a similar design limitation. It would not be surprising if an SATA channel designed for optical drives had SATA 2 speed since I suspect there is no SATA Optical drives that could use more than 3GB/s of data anyway.
I purchased 2 of the 2TB 2.5" hard drives that Dell uses for OEM configurations for this computer, they are Samsung 5400 RPM drives. I have one in a 2.5" internal bay and the other in the optical bay - I converted my Blu Ray Recorder/Writer drive to an external drive. I will do some extended time speed tests on the optical bay drive to see if its performance matches the internal drive (which is the same exact model drive - I have 2 of the same Seagate 2TB drives installed with the same firmware).
I use the pair of 2TB drives to store .vhd and .vhdx drives for test platforms for Hyper-V machines. The virtualized servers with high hard drive utilization get moved to the SSD RAID-0 array, the rest are stored on the 4TB rotational drives.
If you have any questions or comments for me, please let me know. I will see what info I can find on the optical bay SATA revision for this notebook, I am very curious to find out if it is in fact SATA 2. I will let you know what my test results are, I will try to use the AS SSD benchmark program, I believe it will work with rotational drives, otherwise I will find another benchmark utility - do you have a recommendation on which to use?
Thanks again for your info and for pointing out the possible limitation of the optical bay..

Best configuration for RAID-setup?

After reading the post about what FS would be best for 5x500GB, it occurred to me that I have to migrate my RAID-setup soonish and that I would like to hear some more opinions before doing so.
At the moment, my server is running 64bit Arch for 1.5 years now, and it is composed of new parts (C2D 8400, 4GB RAM and 3x320GB HD) with an 'old' 6-port SATA RAID-controller (HP-rebranded Adaptec 2605-card) that I recuperated from our previous office-server. Since I had never worked with RAID before in my life, I was very happy that installing an FS on it and installing arch on that FS went without a hassle.
Now I have to grow the capacity, and although I have some spare ports (3 out of 6 are free), I fear that I'll have to rebuild the FS, since I didn't install LVM. Rebuilding the array might include a risk to lose my data, so I'm thinking of just starting over and doing it right this time:
1. Separate disk for the OS, not in a RAID-array
2. 3-disk RAID-5 array, with LVM
3. Partition the LVM in two slices (1 for work and 1 for 'play').
Are there any considerations I have to think of before doing this? I think Ext4 is the FS-of-choice for a server that will be doing mainly NFS (media), CUPS, and some HTTP/PostgreSQL...

All sounds good to me... I'm not personally a fan of RAID-5 just due to personal preference, but with 3 disks it's your only option really.

Instructions for opening a Satellite Z930 with a slot for SIM card

Hello,
I have a Satellite Z930 which I would like to open in order to replace the original SSD with one having a higher capacity.
The thread http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=279122
was very helpful.
But my PC has a SIM card slot on the right side (side opposite to the microphone and the headphone)
Even after taking off all the 14 screws (including the torx one right in the center), the back cover can not be lifted up on the side of the SIM card slot. Something is holding it back.
Has anyone in the community already succeeded in removing the back cover for this confiuration ?
Thanks in advance for your help.

Randy, Thanks anyway for your time.
After hesitating a bit, I finally decided to remove the SIM tray completely (since that was what was preventing the backcover from coming off).
When you pull at the tray (it is plastic and gray in color and opposite to the audio and video outlets), it does not come off completely when you pull it out normally to maximum (as when inserting a SIM card). You have to frankly tug and pull hard and the plastic tray comes out (just take care not to break it, whch shouldn't happen since the tray is supple and flexible).
Once the tray is out, the back cover comes off (like explained in several videos on the net, especially a good one mentioned by Randy).
Now, I could replace the original factory 128Gb SSD with a 480 Gb disk from mushkin (Atlas mSATA SSD).
This disk from mushkin is just about the right size to go into the Z930, a bit more bigger and it would not have fitted !
Hope this is useful to others.

Best program for greeting cards

which is the best adobe program for layout or creating custom greeting cards? Something like publisher, where I can take the graphics created in photoshop place them in a card template or layout and give them to the printer to run off?

Hard to say, really. The forums are set up assuming people know the answer to the question you asked. Perhaps the Design discussion forum might be a place to start. Although now you have the answer I gave above: InDesign. You might want to visit there and take a look around at what people are talking about.
There was a discussion about how to do greeting cards in the last couple of days: http://www.adobeforums.com/cgi-bin/webx?128@@.3bbda6c9

X61s and slot for sim card slot

Good day.
Some time ago i noticed that i have sim card slot near RAM modules. Machine type: 7666-B4G.
So, i have a question: is it a WWAN modem installed in my notebook?

All X61 models have the moulding in the body shell for a SIM slot, but they don't all have a SIM reader or antennas installed, let alone a 3G card.
Your 7666-B4G config shows as this....
L7700(1.8GHz), 2GB RAM, 100GB 7200rpm HD, 12.1in 1024x768 LCD, Intel X3100, Intel 802.11agn wireless, Bluetooth, Modem, 1Gb Ethernet, Secure chip, Fingerprint reader, 8c Li-Ion, WinVista Business
... so, IMO, its unlikely it is WWAN-ready at any level.
My 7676-3PM came in this config:
T7100(1.8GHz), 1GB RAM, 80GB 5400rpm HD, 12.1in 1024x768 LCD, Intel X3100, Bluetooth, Modem, 1Gb Ethernet, Fingerprint reader, 8c Li-Ion, WinVista Business
... and its very definitely not WWAN ready.

Best slot for PCIE 3.0 x4 SSD in Z97 Mpower

Hi,
I own the Z97 Mpower board and want to purchase one of the new Intel 750 SSDs with PCIE 3.0 x4 interface. The Z97 Mpower has three PCIE 3.0 x16 slots and can be configured as x16, x8/x8 or x8/x4/x4.
My system has a 780GTX card in the first x16 slot.
So, which slot would be the optimal slot to install the Intel 750 PCIE 3.0 x4 SSD?
I know when using multiple video cards in SLI the bandwidth changes, but if I put in the PCIE SSD will it force my video card to x8 bandwidth? or what configuration is the best choice?

Quote from: HenryW on 08-April-15, 06:37:47
Don't use PCIe-4, use PCI-5 or PCIe-7
Yes, of course the PCIE-2, PCIE-5 and PCIE-7 are all the PCIE 3.0 slots, but my question is, when I install an Intel 750 SSD into slot 5 or 7, will that cause the PCIE-2 slot with my video card to run at x8 speed or does it only change the PCIE slots from x16/0/0 to 8/8/0 only if a video card is installed in SLI mode?
Does the PCIE slot bandwidth still adjust down to 8/8/0 even when installing a non-video card?

Which PCIe slot for gphx card?

Hey all:
I have had a problem with my mac pro 2006 rebooting spontaneously. I thought it must be the graphics card and finally pulled the graphics card out and left the mac pro on for a while to see if it would reboot. It didn't. It was solid. No graphics card = no problems, so I assumed it was the graphics card.
So, I decided to swap out my x1900 with a 4870. It's rebooting. I guess this has to do with power to the logic board or something. I have no idea, but I'm super frustrated since this thing isn't under warranty.
I decided to put the graphics card (the new 4870) in the 2nd to bottom PCI slot, rather than the bottom slot. I got a message on startup from the PCI Expansion Slot Utility: http://twitpic.com/2k2jeh
So, things seem to be stable (but I am not counting on it). Is my 4870 not running at full speed in the second slot? I'm not an expert in how the PCI slots are set up, and I'm trying to understand.
I decided to swap

I found this : http://support.apple.com/kb/HT2838
Slot two is 1x + 16x rather than "slot - one" which is just x16... so since slot two has that extra x1 I guess the 4870 cannot perform to its fullest, but pretty close?
I have a suspicion that something in the PCIe slot 1 chain may be broken?... like the power or something? I'm going to lower my fan speed down from 1800 RPM and see if it blows up. It probably will.
Anyone think I just need a new Power Supply, or maybe a new logic board?... how much do those things run? And if I call in on an unsupported system what sort of pricing is it for replacement parts like this? Bad?

Best practice for credit card processing??

Hello,
Our application processes credit card transactions. For whatever reason recently double charges have been happening despite our clients stating they are not submitting the data twice. It kinda doesn't really matter what the cause is as we need a solid server side solution to never let double transactions occur. I have thought of a few methods but I'd very much appreciate someone else's opinion/experience on this. Whatcha think! Many thanks.
We are using coldfusion 8 with SQL Server 2008.
Patrick

My suggestion is to 1) pick a reliable gateway and 2) pick a gateway that allows for pre-settlement auditing.
Double posting is a fact of life when two applications interface to each other. You want a reliable gateway to minimize the occurrence. Because double postings can occasionally occur, I always recommend pre-settlement auditing to make sure application A balances with application B.
A gotcha in the payments industry is when you double post, you get dinged a discount rate and transaction fees -- something like 2.00% + $0.35 as an example. If the double post makes it through interchange, and you need to refund one of the transactions back to the customer, you don't get the original fees back and you will most likely be dinged additional transaction fees (the $0.35 in sample rate). Using my rate example, if your average ticket is $10, your average processing fee is $0.55 ($10 x 2% + $0.35) so a refund will cost you the $0.90 (the original fee that does not get refunded plus another $0.35 for the refund). Now if your average tick is $100, now your approaching $3 for each double posting. If you pre-audit and stop the double posts before interchange, it'll only cost you the single $0.35 fixed fee for the double auth.
Now some API's are better than others and some can stop double postings all together. I still recommend the pre-settlement auditing if notithing else, for volume trending and fraud prevention. Again, a reliable gateway should have a solid API that can prevent double-postings.
