SanDisk Extreme II 120 - 240 and 480 GB SSD review

Posted by: Hilbert Hagedoorn on: 06/03/2013 09:22 PM [ 8 comment(s) ]

SanDisk has released the Extreme II series SSD which we benchmark and review. These SSDs are made 90% by SanDisk themselves including the PCB design and the NAND flash memory. The end result is a blazing fast SSD series that even surprised us when it comes to raw read performance. The SSD series has been developed alongside a Marvel controller tied to SanDisk NAND flash memory, it is amongst the fastest drives we have ever tested.

Wow, they look really good!
A bit let down on write speed, but as you said, at that speed it matters little for most uses, and read speeds are top notch.

I'm sorry if I missed an explanation, but why exactly does the 120GB struggle with write speeds?

^ it reaches "only" 340MB/s while others do 500+

Because 1/2 the output elements gives half the bandwidth.
There is almost no difference between 240GB and 480GB because the bus is already saturated at 240GB.

Aha, I figured that was what it was, but wasn't sure. I don't remember seeing other 120's do so heavily so that's why I asked.

I just checked my SSD and found indexing was enabled. Thanks for the heads-up!
Should compression be enabled? It isn't on mine.
Is it safe to use Disk Cleanup?
I've used several different brands of SSD's, including SanDisk, and have never actually sensed any difference in their operating speeds.
It kind of makes me wonder why anyone except reviewers benchmark their drives.
Unless, of course, you think something is wrong with one.
Even then I'd be more interested in copying the info to another drive before I wasted any time benchmarking it.
Right?

Hi!

last Friday I install my first SSD on my PC and activate de ACHI mode was a nightmare.

After 3 hours of installation (Win7-Win8), many BSOD because AHCI... I found the correct regedit code to activate AHCI on Win8:

"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\"

Hope help somebody!.
