OT: Solid State Disk Speed Test Results

[Jesse]

Well, like i said before i have in my SAC system two Transcend Solid State Disks:

- Transcend 8 GB SATA Solid State Disk SLC (OS Drive) - Model:TS8GSSD25S-S
- Transcend 32 GB SATA Solid State Disk MLC (Storage Drive) - Model:TS32GSSD25S-M

The test consist of 3 Write/Read Request Sizes with 72 Tracks each, using the Hard Disk Speed Test Utility that Bob made:

- 32 KBytes / 72 Tracks
- 128 KBytes / 72 Tracks
- 512 KBytes / 72 Tracks

The following it's the 8 GB SLC Disk:

And the following it's the 32 GB MLC Disk:

As you can see the 32 GB MLC it seems faster than the 8 GB SLC in data test like this, but in the Trascend specs says the 8 GB SLC it's faster in Random Write access, that's why they recommend SLC disks for Operating Systems.

I hope this kind of information will be useful for you guys, if you want to jump into the SSD era compare this results with your current Hard Disks and post the diference here.

I think SAWStudio users will benefit a lot using this kind of disks especially for recording high count tracks or mixing 72 stereo tracks of audio at 24 bits.

Cheers

where can i get that software?

i think RAM will affect the result, because all the data must pass though your RAM to your hard disk.

so i'll give you guys my result

A modern (Core 2) machine can move data through RAM at around 8GB/s. Not a restriction for this kind of test.

considering latency problem of SAC recently, i have do some tests on my hardwares, and here are my result of hard disk, you guys could compare these results to SSD's, although it won't give helps to solve the latency problem. but it really good at recording situation

firest at my macbook pro with bootcamp, and the hard disk has changed to a 7200rpm maxtor

here is the last one

[preachers]

the second computer is a sever machine:

CPU: XEON 5410, Quad Core 2.33G, 12m L2 Cache, Front Side Bus Speed 1333Mhz

Motherboard: asus dsgc-dw, chips 5000x

RAM: FBD sumsung 2G, 800mhz

Hard disk:seagate st373455ss, 73G, SAS, cache 16m, 15000rpm


here is the result, at 128k and 512k, it was extremely fast!
