ATTO Disk Benchmark

The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.

Our basic bandwidth speed tests begin with the Zalman N-Series SSD connected to the Intel ICH10 controller in AHCI mode, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 128GB model we received reveals 286 MBps maximum read speed that plateaus from 128-8192 KB file chunks, and 273 MBps peak write bandwidth plateaus from 64-8192 KB. These both exceed SandForce specifications, and meet the manufacturer's own specification.

Although I do not currently own this drive my current drive has the Sandforce controller and man does it smoke! I have 2x 120gig OCZ's in Raid 0 and the performance is stellar.

I agree that SSD is the way to go, but as the reviewer stated, it's the price point that's keeping myself and others away from full adoption. I also don't own the drive reviewed I also don't use one in my desktop as I favor the VelociRaptor 740 (running plenty strong since purchased in 2004) with other WD 7200rpm drives for storage and non-essential programs as a secondary drive(s). I do use a 64GB RunCore SSD in my HP netbook (1030nr) running the full version of Windows 7. I love both products, but while the raptor drives exist and the SSD technology is still young, I can't make the leap. As always, I will keep my eye out for price drops, trim/garbage improvements, etc. (thanks benchmarkreviews!!!) in hopes that in the months/years to come the price, stability, performance and longevity of SSDs nears that of the VelociRaptor drives.

Good review. Anything in the included documentation as to this being 34nm technology? I've included an article link below that I found interesting. Maybe the technology is reaching some limits to nand production/performance. Maybe we're about to see rapid (or more rapid) competition of the SSD controller development/deployment. That seems to be amongst the better design improvements anyway.

It also makes me think that hybrid drive development may get a push when thinking of nand, controllers, price, and real world applications. Any word on the street of upcoming changes in the industry?

Sorry Robert, but the Zalman documentation is VERY scarce on information. I had to write to the manufacturer just to find out what the rated IOPS for this drive was. It is unlikely that this SSD is using 34nm technology, as it's physically the same drive as other SF-1200 SSDs. All that separates most SandForce-driven SSDs is firmware licensing.

It would be nice if the Crucial RealSSD drives were tested, to see how they stack up.

Was looking at the Random 4k/QD32 results as I wrote this. I wouldn't have thought it be that far down the list.

Glad you found it. While the Crucial RealSSD C300 is very fast, it's not so great at managing the same operational workload as SandForce SSDs.

Anyone know when we will see ssds with sanforce 2500 and 2600 controllers?
The C300 fell in price to $450 for 256 gig, and OCZ vertex 2 is usually on sale for 120 gig for $ 150 after MIR @ newegg. The revo x2 is on sale to as well for $ 564.

March or later. Even then, the new SandForce SSDs are targeted towards enterprise storage.

Hi, can someone tell me the height of this remarkable ssd? Thanks in advance!

# RE: HeightOlin Coles 2011-05-24 15:52
Measured with calipers for you: 2.75" wide, 0.40" tall, and 3.95" long.

# RE: HeightEmilio 2011-05-24 17:56
Thank you very much for your fast response, but 2.40 inch tall? Is this correct? That is about 60 milimmeters, I was hoping something between 9,5 and 12 milimeters. Perhaps 2.4 is the tall of the box?

Oops, that's supposed to be 0.40" tall. I'll fix it.

Thank you!!! Im going to buy this SSD for my hp mini 311, wich uses a 0.37" drive. That is less than 1 mm of difference. Dont think it will be a problem. Thanks again.

What is the make and model of your current hard drive?
