OCZ Technology was kind enough to send us their latest high
performance PCIe solid state drive for review; the MLC based RevoDrive X2 240GB.
The RevoDrive X2 series of drives are fairly unusual in that they are not
housed in either a 2.5 form factor case, or indeed a 3.5 inch housing. Instead
OCZ have built what can only be described as an extreme SSD solution. Instead
of using a slow SATA interface, the RevoDrive X2 is mounted on a x4 PCIe card.
This removes the shackles and allows the extreme performance that the RevoDrive
X2 can deliver.
The specifications of the OCZ RevoDrive certainly have the
There are 4 SandForce SF-1200 series SSD controllers onboard, each with its own
bank of 34nm MLC NAND, with capacities ranging from 100GB right up to 960GB.
- Read speeds at up to 740MB/s
- Write speeds at up to 720MB/s
- 4K random writes at up to 120,000 IOPS
- RevoDrive X2 can be used as a boot drive or as a storage
The specifications of the OCZ RevoDrive X2 are certainly
very impressive, but can the RevoDrive X2 really deliver this level of
So let’s find out how this new SSD performs in our range of
benchmarks and real world tests in this review.
OCZ Technology company information
I’m sure most MyCE members will be familiar with the OCZ
Technology brand name. OCZ has been manufacturing high performance PC memory,
SSDs, and other PC related hardware for many years.

the outer box, you will find a more robust box, which contains the RevoDrive X2.
This box is a strong affair, made from quite thick cardboard.
the internal box we can also see the RevoDrive X2 PCIe x4, and the card is well
protected by foam packing.
What’s inside the box
Now it’s time to take a look at the drive itself and what it
came shipped with.
The package contained the OCZ RevoDrive X2, a nice label to
place somewhere prominent on your PC case to make your friends drool, and
Now let’s take a look at the drive itself.
RevoDrive X2 240GB
As we have already seen, the RevoDrive X2 is housed on a
PCIe x4 card. What we have is basically four OCZ SandForce SF-1200 series based
SSDs, minus the SATA and power connectors. Each of the four SSDs have their own
SandForce SF-1200 series SSD controller, and their own bank of Intel branded 34nm
MLC NAND. In the case of our review sample which has a capacity of 240GB, each
bank of NAND is 64GB in capacity.
Each of these (internal) SSDs is connected to a Silicon
Image SiI 3124 RAID controller in a RAID 0 configuration (by default), and in
turn, the SiI 3124 is connected to a Pericom PI7C9X130 PCIe to PCI-X bridge.
The original RevoDrive came supplied with two SandForce SF-1200
series controllers, and two banks of 34nm MLC NAND. The RevoDrive X2, as we
have already stated has four SandForce SF 1200 series controllers and four
banks of 34nm MLC NAND. The extra two controllers and banks of NAND are fitted
by means of the daughter board which we can see in our above screen shot.

Drive maintenance features
With the RevoDrive X2 using a RAID 0 configuration, there is
no TRIM support at present, so the RevoDrive X2 will have to rely on the
effectiveness of its own garbage collection algorithms. If this turns out to be
as good at the OCZ Vertex 2, then there is certainly no need to worry about the
lack of TRIM, as the Vertex 2 is very capable of maintaining its performance,
even without TRIM.
From the short time I have been using the RevoDrive X2;
there is certainly no evidence of performance dropping off due to the lack of
Despite what other sites have said about “Secure Erase and
the OCZ RevoDrive and RevoDrive X2”. The drive does support internal Secure
Erase, and it’s certainly possible and very easy to Secure Erase the RevoDrive X2.
Internal Secure Erase (SE) on an SSD that supports it, will
restore all NAND on the drive back to its clean (factory default) state.
You will require a special Linux distribution to secure
erase the RevoDrive X2 using a point and click GUI, but most Linux
distributions will secure erase the RevoDrive X2 via the terminal application
In either case, all that is required is a small USB flash
drive/stick or a blank CD to accommodate the “Live” Linux distribution. I can
certainly recommend the point and click GUI version. Don’t panic about the word
“Linux” being used here, it’s all very simple to use.
Praz over at OCZ has produced an excellent, easy to follow
guide for the GUI version. It’s a very worthwhile read.
