SSD help please I am so confused!!


[link to this post]
 
Hiya,

I have decided to upgrade to SSDs but now I have started reading about them I am so confused.

My PC has a RocketRaid 174x Sata II Controller (approx 2006) so at first I was going to do a RAID 0 array but then I have been reading about TRIM and I do not my RAID controller will support TRIM.
So am I best going for one large SSD and using TRIM
or
2 smaller SSDs in RAID 0 and forgoing TRIM?

Thanks,
Steve

This article is a bit out-of-date I'd imagine, but worth a read: http://www.anandtech.com/show/2738

There is no trim support with raid in windows 7.

Thanks for the replies, Ive read most of that article

I have been in contact with the manufacturer of the RAID card and they say it does not support TRIM.
So is it even worth considering SSDs or are there other options? I have read something about SSDs having built in Garbage Collection can this replace TRIM?

I take it your computer have not got built in Sata then? i wondering why you want raid.

i got a SSD and I think it is great,r eally fast, but not sure if it is worth the price.

What I did get before was a Seagate Monentus Xt drive, this is a 500Gb 2.5 inch drive with 4Gb of SSD memory. It cost about £80.


It was and still is a fast drive, but I had problems with it, which is why it is now a second drive. If seagate can sort out the problems then it is a great idea and and is a good step between a normal drive and a SSD.

the problem I had was it kept shutting down, so my computer would crash, either a BSD or just bits of software would fail. Other people had the same problem. But just before i had my SSD unit I solved the problem, i stuck a jumper on the pins of the drive, which shuts down the power management of the drive and it became stable.

It is a clients ACME portable PC, it does have onboard SATA as well (Asus Stryker 2 mobo) but am unsure as to how to get into the actual motherboard to change the connections over if necessary

He just wants the PC to be as fast as possible as he uses it for 3D graphics. He has a normal HDD for storage so SSDs seem the best way to go.

If high-speed 3D graphics is the objective, are you certain that an SSD is what is needed? How much poke do the CPU, memory and graphics adapter have? Why not post the full system spec?

There is new firmware, SD25 which resolves that problem.

I am interested to know which pins you jumpered, there is only one reference to jumpering which forces the drive into SATA1 mode.

Full system specs
Q9450
4GB RAM
2 x Nvidia GTX280 in SLI
2 x 750GB Sata2 drives in RAID 0 (these are what I intend to replace with SSD)
Asus Stryker II mobo

Its for 3D graphics design so the faster the better

Looks 'pokey' enough providing that memory has been configured correctly. Presumably, the main bottleneck is getting large graphics files on and off the disk drive, in which case an SSD will help. Have you checked if the system is paging? If it is, more memory might be the answer.

Also, note that RAID 1 will slow down writes to disk drives, although reads will be unaffected.

Finally, if you have been given the task of optimising the performance of a particular graphics package, you will not be able to do this properly without running (and monitoring) the software concerned.

I cant check anything at the moment because one of the drives in the RAID array has bad sectors and Vista refuses to boot. I have installed Windows on another drive and can recover the data from the RAID so as the drives need replacing that is why we are thinking SSDs.

Now I am thinking about a single Sata 3 SSD and a PCIx Sata 3 card...

Thanks for your help

those are the jumpers I used, yes you are right they are suppose to put the drive into Sata1 mode, but the software I used to check , told me it was still sata2, but had no power management.

when I took the jumper off it said power management was back on. i may have put the jumper on the other pins, but I don't think I did.

I got it and eventually managed to update the drive and I thought it done the job at first and after a couple of days, I had the same problem.

The drive have got faults as you can tell if you look around the net, which is a shame as it is a good idea. but this is Seagate for you. i always seem to have problems with Seagate drives, not buying another Seagate, the scary thing is that soon we will have even less choice when Seagate and WD buy between them what is more or less the last hard drive manufactures
