The OCZ Vertex EX series drive came in a plain black box that contained the 120GB version! Before we go any further let’s take a look to see what OCZ has to say about this series of SSDs.

Looks like we have a screamer on our hands for sure, so without further ado…

OCZ Vertex EX 120GB SSD Retail Box

The OCZ Vertex EX series 120GB SATA II 2.5″ Solid State
Drive comes in a small box that lists all the key features of the
drive. OCZ also has 60GB versions of the Vertex EX on the
market in case you were wanting a different size. It should be noted that all capacities have the same controller and 64MB of cache, but they do differ in write speeds due to the density of the SLC NAND Flash. As a result the 120GB model has a write speed of up to 210MB/s, while the 60GB model has a write speed of up to 200MB/s. So, a 10MB/s difference is seen on the write speeds and the read speed is identical at 260MB/s. The pricing on the other hand is not identical between the two models.

OCZ Vertex EX 120GB SSD

The Vertex EX uses the 2.5″ form factor used in notebooks, so this
drive will work in any notebook. If you wanted to be able to mount it
in a desktop chassis with 3.5″ bays you’ll be forced to use something
like the OCZ Solid State Drive 3.5″ Adaptor Bracket in order to get it bolted up in the system properly. You’ll need to
secure it as the 120GB version of the Vertex can read up to 260 MB/s
and write up to 210MB/s. Actually, a little double sided tape will work
and you can stick it any place your heart desires as these drives have
no moving parts and don’t make any noise.

Flipping the Vertex EX SSD over you get a better look at the
SATA II header and the SATA power connector. OCZ states that the Vertex
series has a MTBF (Mean Time Before Failure) of 1.5 million hours and
can tolerate a force of 1500G, so this is one tough drive. OCZ backs the
Vertex EX series with a three year warranty as well, so you are covered if
something happens to go wrong. This warranty period is one year longer than the Vertex MLC drives, so the Vertex EX SLC drives do have a better warranty period.
