In my impression, SanDisk is well known brand in Taiwan for years.
My first SanDisk product was CF card for digital SLR camera.
After another, I also used or researched other brands CF and SD card. I think memory card is key field of SanDisk.
SanDisk has wide range product lines of high spec. memory card. Itís also one of few brands to have SLC products.

Previously, I saw some SanDisk SSD products from internet were SATA2 and mSATA.
I felt they more focus on NoteBook and didnít see any SATA3 high bandwidth product yet.
However, in March, I started to see more news about SanDisk SATA3 SSD in internet and market.
For current competitive SSD market, launching SSD this stage needs to own real strength and right position.

First of all, letís look at SanDisk Extreme SSD packing.
Itís same design style with his memory card. The simple design uses black as main color to combine with red lines or characters.

Left side is SanDisk Extreme 240GB and sticker. Right side is multi-languages products manual.
If they can bundle 2.5Ē to 3.5Ē adapter, that would be better.


Itís 2.5Ē and the capacity is 240GB. In official spec, max Sequential Read/Write is 550/520 MB/s.
Max random Read/ Write is 39K/83K IOPS. Itís the SATA3 SSD highest spec in the market so far.


The model name is SDSSDX-240G-G25. This series has 120, 240 and 480GB.
Itís glossy black metal shell. The texture of outlook is elegant.
Controller chip is SandForce SF-2281. This chip has launched almost one year. Many major brands SSD are also using SF-2281.


Backside sticker shows all safety certificate and information.
The screws are under sticker which is different with general design.
If you want to see controller and NAND Flash inside, you can search the pictures from internet.
As warranty and hardware safety, I recommend you to keep it as original.


Lower right is SATA3 and power connector. Itís same as SATA1 or SATA2.
You need to check the packing or product spec to know if itís SATA3 SSD.


Screw holes are 2.5Ē standard. It supports NoteBook.
Now, many PC Case also support 2.5Ē rack. 2.5Ē to 3.5Ē adaptor is not really necessary for PC users.


SanDisk Extreme uses SandForce SF-2281 controller. Itís very popular SATA3 SSD controller.
It uses anDisk 24nm Synchronize NAND Flash. The individual IC is 32GB.
NAND Flash IC is very special. Normally, SandForce SF-2281 bundles with Intel or Micron IC.
For the performance, letís follow on the test result below.

First, I use Intel DeskTop platform. Itís GIGABYTE latest Z77X-UD5H-WB WIFI.
It supprts 3 PCI-E X16, 3 PCI-E X1 and 1 PCI. Itís good extensibility in ATX size.


Z77 built-in GPU supports simultaneously three outputs. Itís also first time native support USB 3.0.
Exclusive BT4.0 and Wi-Fi PCI-E card enhance connection between PC and mobile devices indoor.


Intel Z77 is latest mid to high end chipset. Itís getting popular.
Intel chipset always gets better I/O transfer rate. SATA3 SSD can have better performance on it.
