I ald read SSD and SAS. Just dnt hv SAS 6GB/s vs SSD. The test of momentus TX vs SAS 6GB/s.
Momentus using 4GB SSD as memory. It only faster in reading but writing just like normal hard disc.

I'm thinking to use 300GB SSD 6GB/s as main drive, 64 GB SSD as virtual drive,1 drive as application, 2 as data storage (use for data reading by application).
Samsung F3, Momentus, WD15k RPM SAS 6GB/s. no idea which one performance/price wise.
1T 7.2k RPM 6GB/s near liner SAS cost RM1.6k
300GB 15k RPM 6GB/s SAS cost RM1.3k
500GB seagate momentus TX ~RM500++ ~RM1/GB (reading should be around 140Mb/s)

I failed to search the benchmark result about them.
It's good to use 2x Corsair 120GB SSD (550/520mb/s read and write).
It's impossible to RAID 5 of them ?

ur seq write speed is lower than specs, i think should update mobo chipset + Intel RST driver.
my scores for G3 160GB running is as below:

noted

is my read/write good? please advice.

U r really a master. I connected to sata3 port coz I tot I need the achi mode. Will try connect other port and test later. Thanks

anyone can teach me how to configure RAID ?
If got two same SSD, 1 7.2k RPM 64mb buffer, and 10k RPM
Can i RAID them all to Raid 1 and RAID 5 ?
Or can i RAID 10 to two SSD, and dnt RAID the remaining drive since remaining is SAS and non SAS?

your read/write is good. but pls post another bench after u done with optimization

Added on January 16, 2012, 1:55 amno bro . i am using 80gb only.. thats y my sequential write is about half of what u got

From what i know, people usually recommend same type of HDD for RAID.

You can't raid SSD with HDD.

btw, Raid can be configured with your Motherboard Bios, as long as your mobo supports RAID Configuration. Btw do you understand RAID?(judging from what you said RAID 1 and RAID 5 and RAID 10, i believe you don't understand them)
More Information on RAID : http://en.wikipedia.org/wiki/RAID
RAID Explained in Diagrams : http://www.thegeekstuff.com/2010/08/raid-levels-tutorial/

Currently, i don't recommend you doing RAID with SSD since they still not yet have Trim support.(sorry, i`m quite slowpoke in this, i only know Trim support for RAID will be available in future, if it's already available, please point out, thanks)

After optimization, but out of all those optimizations, i left out 4 i think cuz i'm too noob

after change port i got the speed what my SSD sud have.



isit normal for my 4k qd32 read speed?

funny coz your 4k speed before optimization was better than latest result although there are some improvements in sequential but u lost a lot on 4k. i'd say u still not getting the right speed. your 4k shud be more than or at least 20mb/s. have u installed the latest intel RST driver? then do the optimization shown in the 1 post. but pls be reminded that some optimization are not for intel ssd and some are not for sandforce. it is written in the optimization page.

look at my result. this is what u shud be getting for read speed.

yupe, u need to use ACHI mode to enable TRIM.
the IDE mode is just to sort out problem u had during firmware upgrade.
but now it seems to work fine for u. Congratz!

I had read those link yesterday.
I was thinking whether should i use the advantage of RAID or not.
First, i can not afford any failure data. 2nd, It's use for critical performance.
RAID 0 totally out of my mind. I need to set a duplicate back up. It's RAID 1 is the good option ?
Can i just raid 3 of the Hard disc leaving SSD un-RAID ?? I saw a benchmark that RAID 5 of the samsung SAS greatly improve the performance.
By the way, any good idea to customize hard drive with SSD.
Install main OS on SSD. Application on 2nd hard disc. read data from storage 1. Keep data in to storage 2 and storage 3 which may be used again by application.
I hv no idea which hard drive to use for the rest of it. using 5 SSD or 1 SSD 4 SAS which is over budget.

Read intensive application such as 3D editing, Photoshop and OS should be in SSD.
While Media and additional important files can be store in HDD.
Single SSD performance is good enough for users without the need to RAID.

May i ask what's your intention for RAID?

Only same size of HDD can be RAID.
http://www.tomshardware.com/reviews/HETERO...-WORK,1789.html
You can't raid a 500gb with 1tb.

Plus, if you're saving cost and RAID a 7.2k rpm HDD and 10k rpm HDD(if they are in same size)
The performance will be bottleneck by the 7.2 rpm HDD because 7.2k rpm HDD has inferior performance compare to 10k rpm

RAID HDD does not means, HDD 1 Performance + HDD 2 Performance = Total Performance.

RAID 5 Requires atleast 3 SSD or 3 SAS HDD.

The application i use is process, ram, reading and writing intensive.
I saw the benchmark showing RAID can increase the performance provided it full fill the condition.
I hope with RAID it can speed the process and reduce time consuming.

In order to use RAID 5, I need to increase my budget. Budget 2.5k kind hard to use 3 SAS + 3 SSD.
WD Raptor 160GB cost RM899 ... that why i go to momentus TX
My target is Performance/price. Reading form storage is important, yet writing on storage should be fine for me.

Got ppl said that Dell Tower server T610 can not simply plug in hard drive. The BIOS may be can not support certain SSD and else T.T
Currently, I'm customizing it in order to reduce cost.

u shud know momentus xt only read a specific amount of data which are frequently used with high speed. other than that it will take some time to read non frequent data, correct me if i am wrong

I assume that the largest file will be use for application read will be about 13GB ++ with ~10m to 100m small files. I/O also important...
Then, should use SSD since it's stable >__<
5pcs of 120GB SSD ...OMG ... over budget...

SSD is not recommended for Write intensive since it will degrade it's performance.

If you're going for Write intensive work load, go for SAS HDD

OMG ... I want to cry ald.
So, my combination should 2x SSD (Read 550mb/s; Write 520Mb/s), 1 15k RPM 6GB/s SAS for application (Intensive application), 1 normal, 2 storage ?
Look like this server really user inconvenient >.<
If read intensively, it's ok ?

Just Hard drive itself causing so much problem.
HVnt go to controller, RAM, Processor, networking controller
