Inside the Vertex LE SSD

Since we have never seen what components are being used inside the OCZ Vertex Limited Edition SSD series we opened up our 100GB Vertex LE drive to see what the internals look like. Breaking the warranty sticker and opening up the drive will VOID your warranty, so don't do this unless you don't mind losing the warranty on an expensive SSD.

OCZ Vertex LE 100GB SSD Inside

After removing the four small Philips head screws that hold down the Vertex LE (Limited Edition) Series cover we were able to lift off the cover and see what makes this little SSD tick.

Here is a closer look at the main component side of the PCB where you can make out eight Intel 34nm MLC NAND Flash memory chips and the highly anticipated SandForce 1500 controller that is being used on this drive and the Vertex 2 EX SLC series of SSDs. Notice that the controller is now branded as OCZ, but it isn't too hard to figure out who really makes it. The regular Vertex 2 SSDs will be using the SandForce 1200 controller, which has a build cost that will be $100 cheaper. Since OCZ has scraped the idea of bringing to market the Vertex 2 Pro it is highly likely that this limited edition drive is basically the inventory of Vertex 2 Pro drives with a slower, but more reliable and stable firmware from what we can gather.

Flipping the PCB over we can take a look at the other side, which is bare and has just eight more Intel MLC NAND memory chips on it. The location of the large 'super capacitor' is present, but you will notice that the Cap-XX is missing in action. We asked OCZ what happened to it and were told the following:

"This will NOT be present on the consumer class devices Vertex LE, and Vertex 2. This will only be on our enterprise class Deneva product line. Basically what it's for is in event of a sudden power loss the drive will go into a mode where it will focus on completing write commands using the power in the super cap. Its only enough for a short burst, but it's enough to get the job done. This is important on SSDs more so than HDDs in enterprise. On an HDD when write caching is turned off, the last write command is lost, but the rest of your data is secure. On standard SSDs because of the nature of Flash and Flash management it is not typically possible to guarantee data integrity on sudden power loss. The enterprise class Deneva Series will be the first high performance readily available SSD that guarantees data integrity on sudden power loss. As a bonus effect the last write does in fact complete so no data is lost..." OCZ PR

OCZ Vertex LE 100GB SSD SF-1500 Controller

The heart and soul the Vertex LE is the SF-1500 controller seen above. As we noted, the Vertex LE doesn't have any cache chips on it as that is because the SandForce controller itself is said to carry a small cache inside that is a number of megabytes in size. Inside the controller there's also the Tensilica DC_570T CPU core; this is used in both the SF-1200 and SF-1500 models. This controller includes support for all the latest features like native TRIM support. OCZ claims maximum read/write performance of 270/250 MB/s with their revision 1.0 firmware. This is a more recent firmware build than what we used when we tested the Vertex 2 Pro last week, so it should be interesting to see how these two drives compare.

OCZ Vertex LE 100GB SSD Intel 29F64G08CAMDB
The OCZ Vertex 2 Pro features Intel 29F64G08CAMDB MLC flash memory. In total there are 16 chips and each IC is 8GB in density. That adds up to 128GB of storage space, but only 93.1GB of it will be usable space!
