Apple :: RAID 0 On My PB
Apr 27, 2009I have got 2 HDDs in my PB12". If I do a RAID0 using Tiger, would I get a performance hit instead of getting more speed from the HDDs?

View 10 RepliesHere's my story and, let's say, my analysis:
I bought a generic 2 HD sata2 RAID1 enclosure based on the chipset Silicon Image SteelVine 5744. It can be used in USB or eSATA2. This embedded chipset (named SiL5744) is known (understand "claimed") to auto-handle Sata I/II and host sata2 controllers that not support the port multiplier feature. The HD are two Samsung F1 1To. There's no jumper to rollback to SATA 1.5Go on them, you can only do it by flashing the HD's bios, however we don't need to do it as I wrote just before, the SiL5744 supports SATA 3Go natively.
The enclosure works pretty well with USB, but *not* in eSATA : the E6500 freezes/hangs just after the POST step (a potential driver issue with the installed vista 64bits is not the reason then). As soon has I disconnect the eSATA cable, the system recovers and continues as normal.
What I've tried/done so far :
Both E6500's BIOS SATA mode AHCI and IRRT mode were tested,
Intel Matrix driver and software was updated to the latest 8.7.0.1007 version (AHCI and IRRT),
The SiL5744 chip was upgraded to its latest firmware as well (in case of...)
In order to verify the esata cable, the HDs and the enclosure itself, I succeed to :
- Use the enclosure's RAID1 feature when using the USB connection, I could partition,format, and read/write on the logical volume
- directly connect *one* HD (Samsung F1 1To) to the E6500's esata port -(I have a sata2esata cable), Vista installed it and I was able to use it as normal, even the hotswap feature seemed to work fine (I unkindly removed it). I could so test both HD individually this way... On the enclosure hardware side, everything looks fine then.
An IMPORTANT thing : The E6500's ICH8/9-M sata host controller seems to support the Port Multiplier feature *ONLY* on sata port 0 -as a bubble message from the Intel Matrix soft sometimes shows up-, but this is exactly where the internal HD is plugged on the motherboard I found nowhere you can change the internal sata port ID (switch,bios,ect...). I think this is the key of the problem that seems to be a dumb port conflict, because the esata port is in fact the port sata 4 (the DVDRW drive is sata 1, dock's esata is 5 for instance). If somebody knows how to swap the sata port ID, I think I won't be toasted !
I purchased a Sony AW230J/H believing it would be easy to convert to a RAID 0 array by installing my 2 Intel SSD drives. Turns out on this particular model they turned the RAID options off in the BIOS so I can't access it, and install a NON-RAID version of Intel Storage! But, striping/mirroring are available in the native VISTA Storage of Manage Computer! So, how can I create a RAID on drives that are already being used to boot into the OS? Or does anyone know any tricks to turn ON the RAID Bios so I can configure it PRE-OS installation? When I right click on the 2nd SSD (unpartiioned) all options for mirrow/striping/etc are available, but no drives to add to it. My primary drive has those items greyed out?

I'm about to take the plunge and order the vaio z from sonystyle uk, i was looking for the fastest, reasonably portable with good resolution laptop, and while I was looking for screen little bit bigger than the vaio z (15"-16") I couldn't really find anything that would go as fast the vaio z while still being under 17" and light enough to carry around.
But all my searching was based on the fact that I want to raid 0 two fast SSDs.
But is it really worth it? will two x18-Ms in Raid0 on the vaio z raid controller be really faster than one x25-M?
Also is it possible to DIY the raid? I did some reading and while I found some threads talking about the parts used to do the raid i couldn't get a clear answer whether it's easy to do the raid yourself.
One other question is that on sonysyle uk you have the most expensive vaio z having the carbon fibre option, while anything cheaper doesn't say so, does that mean the others are not carbon fibre? how different would a carbon fibre vaio z be VS non carbon fibre?
I bought a HDX 18 here in the UK, it came specced with 2 x 250GB HDD's...
I'd have liked to run them in a RAID 0 config but not sure if I can? I know that in the US you were given the option of RAID HDD's?
I tried to backup my M6400 with Acronis. The backup works fine, but I'm not able to restore ....

I want to be able to dual boot with XP, but am needing a raid driver.
I have installed XP on a partition on the hard drive but if I want to boot up XP I have to change the option in the bios, which does get a bit of a pain.
Is the quad raid 0 512Gb on the Z the fastest setup in the laptop/mobile world?
How does it compare to the 512GB SSD setup on the new MBP or even the Alienware 15x and 17x?
I asked this on the Alienware forum; but nobody truly knows much other than that the alienware would demolish the Z and that the ssd on the Z is a dual setup like the mbp and alienware. I know its a quad setup, but is it the fastest option availble?
I was under the impression tht it was, and it would be extraordinary on such a tiny laptop.
Does anybody know if the SSDs on the Z series use the slower MLC flash memory or do they use the more efficient (and expensive) SLC flash memory?
View 10 Replies View RelatedI'm thinking of purchasing the new sony Z-1190 laptop. Some of the options have only one drive (say 128GB X 1, or 256 X 1) but still supposedly have raid 0. How is this possible (I thought that more than one drive was needed)? Would there be a performance difference between the 256X1 or the 192 (64X1 + 128X1)?

View 5 Replies View RelatedPicked up a great deal on a 1730 with a 128SSD and 320 2nd drive - Does anyone know if the 120 will be faster than if I were to go with 2 7200 rpm drives? The price difference for the SSD is "UP THERE" so I at least want to know if its as fast as a conventional 2 hard drive raid zero approach.
Also does anyone have any links to spec's for the Dell 128SSD? Is it the Memoright 128GB.
This is a weird one, my new M1730 has RAID 0 2x160GB but they are different makes of hard drive:
Hard Drive Member 1: Hitachi HTS722016K9A300
Hard Drive Member 2: FUJITSU MHW2160BJ G2
If you are an M1730 owner I would be interested in what drives you have. Dell have tried to fob me off and told me all M1730 have this config.
Although it works OK I can't see that this is good practice - I would have expected matched drives.
I've noticed the improvements are relevant but not as big as I expected, I think with normal HD the RAID0 performance will be much better than a single HD drive, any experience using SSD in RAID0 configuration

I was browsing at an online store today and I see that Intel has released 1.8" 160GB drives! These are 5mm thick.
Now I have upgraded my Z to a single 160G (2.5") but these should slip right in!
Does anyone know where I can get the required cable and the tray for the z-series notebooks
I've got the HDD option, which replaces the optical drive with a normal HDD, and doesn't come with proprietary Sony SSDs. I've been thinking about and testing RAID configurations, and this thread is meant to gather some thoughts on that. At some level it's probably easier to go the Sony SSD route, but... I prefer something else
There are two parts: (1) external RAID, (2) internal RAID.
Part 1: External RAID
I went down this path because I believed that there's only one SATA port offered by the HDD-option. From Intel [url], it appears that the port multiplier functionality is not implemented in the ICH8, which is what the Z1 comes with. This means we can't get two or more drives to logically share the same SATA port, which means that they have to appear as one logical device, which in turn means that some sort of external RAID/BIG hardware is needed.
I tried a number of hardware RAID solutions. The first was the Silicon Image SiI 4726, in a mini-board with a form between the 2.5" and 1.8" drives. Unfortunately, after configuration on a (old) desktop, the chip offers only its admin drive ("Config") to the bios and Windows, rendering it impossible to boot off of...........
how much faster are the tri and quad raid configurations compared to dual raid? I know bench tests show that the tri and quad raid are significantly faster but how does this translate into real world use? will opening programs be twice as fast or games will load twice as fast?

From HP website:
Versatile storage options include the ability to add two solid-state drives in a RAID-0 configuration to improve the overall speed of the ENVY 15 while providing excellent disk performance.
Now my question:
It's possible to use RAID 0 using two HD 7200rpm?
The default one comes with 500GB Seagate then I'll buy another one of this + the hd caddy and cable to install it.
I have a Dell 1749 into which I have installed two OCZ Vertex 3 MaxIOPS SSD drives. Boot times are pretty fast using a single, non-raid, drive but I was thinking of configuring the two drives in a RAID 0 configuration to boost speed a bit further. I could not find anything in the bios settings that would allow the SATA controller to go to a RAID configuration. I guess, therefore, that at least the laptop that I have does not have RAID capabilities. Were there any Studio 1749 system boards that did indeed support RAID?

The question is will windows defrag tool, know how to properly handle the 1/2 and 1/2 file fragments on both drives?
I would assume that it would, by simply moving a fragment and it's assosiated 1/2 on the other drive to the same spot on both disks? Or would it not?
If it's not, what defrag tools are RAID 0 compatible?
A serious question when you consider VISTA's "advanced" or more correctly "complicated" page/swap file use and RAID 0. The way I see it, is under defragmentation a raid configuration could be realy hurt by fragmentation as you effectively double the normal rate of fragmentation in a RAID configuration.
First have 2 drives of course. main drive and a Optical 2 SATA or PATA.
my howto is for a 320 and a 250 raided giving you 250/250 =465 real gb of space.
first partition the 320 drive when installing XP PRO so that you have your main partition 70gb and the rest leave for later. also just leave the other drive for later as well.
Install windows XP pro on the 70gb partition.
get your drivers etc programs etc and all other shit that you want setup.
next hack the registry to enable Dynamic Drives on XP-PRO. Funny cuz they say that you can't get dynamic drives on notebooks. not even with XP PRO.
go into :
HKEY_LOCAL_MACHINESystemCurrentControlSetServices
and change the following
.
in the services dir there is each reg dir and the corresponding start value.
you must change the start value to whats below.
dmadmin: 3
dmboot: 4
dmio: 0
dmload: 0
dmserver: 2
after that reboot.
then go into control panel, admin tools, computer management and then disk management.
right click on the windows drive and click on convert to dynamic.
it will pop up with a list of drives you have *2 of course cuz thats all we have* so check the other drive. and convert to dynamic. just say ok to the next few things it asks you. and reboot.
after reboot go back into disk management and right click on the second partition in the windows drive and click "new volume" and choose stripped in the list for what kind of volume. click next until format and do a quick format.
bingo you just created a raid 0 drive which will not be redundant but will be UBER QUICK.
mine has a 8ms response time.
sorry for my crappy howto. but I really wanted raid in my notebook and there was no howto's so it took alot of digging.

My RAID failed yesterday and one of the new drives I bought is dead. I only had it for less than a day.
I don't know if it is was the drive or RAID but either way the drive does not work but the connector does so.
I'm most likely going to send a ram module I bought back as I’m unsure the voltages of that ram.
My keyboard also developed a problem. Not all the keys work. I looked at it and the connector is burnt the middle of it. The keyboard connector is what goes into the sound board. I'm not 100% certain how it happened may be it was either the ram or RAID that did that or some other unrelated fluke caused by something else. I kept on powering of and on without logging of in test mode and may be that did it. I'm not a smoker and I never physically did that.
The ram I originally had was 7-10-F1 the ram I bought was a 4GB 7-10-F2. I think what has confused me is that I googled and read that the ram I bought was CL8 when I had originally CL7 it makes no sense to me to me that ram could be CL8 when the first letter is C7?
I put my laptop on my desk like I normally do and it just turned off. I powered it on and it said no OS found. I opened it and the connector looked fine and the KB was ok at that point..................

RAID 0 as defined from this Wikipedia Article
Quote:
RAID 0
RAID 0 (striped disks) distributes data across multiple disks in a way that gives improved speed at any given instant. If one disk fails, however, all of the data on the array will be lost, as there is neither parity nor mirroring. In this regard, RAID 0 is somewhat of a misnomer, in that RAID 0 is non-redundant. A RAID 0 array requires a minimum of two drives. A RAID 0 configuration can be applied to a single drive provided that the RAID controller is hardware and not software (i.e. OS-based arrays) and allows for such configuration. This allows a single drive to be added to a controller already containing another RAID configuration when the user does not wish to add the additional drive to the existing array. In this case, the controller would be set up as RAID only (as opposed to SCSI only (no RAID)), which requires that each individual drive be a part of some sort of RAID array...............
