SanDisk Extreme II 

Released July, 2013
  • 480 GB
  • 2.5" SATA III
  • 256 MB
Benchmark Results: In terms of IOPS performance, all three drives performed very similarly with outstanding read numbers and very good writes.

Definitely faster than the previous version of the Marvell controller, it plays nice with the newer and smaller architecture NAND all the new drives are sporting.

Reviews Word on the street for the SanDisk Extreme II


8.0
But with so many drives using the same controller, are we not entering into the SandForce territory of days gone by, where all drive performance was relatively equal?

What People Are Saying Give it to me straight

Performance

IOPS performance was strong with reads/writes hitting just over 90K and nearly 70K respectively.
by Legit Reviews (Jun, 2013)
It puts out some really nice numbers and in fact SanDisk has even stated that the Extreme II drives are the fastest retail drives they've outed to date.
by Legit Reviews (Jun, 2013)
The performance doesn't really dip on the incompressible data like we saw with the first Extreme series of drives so overall performance is more consistent and faster.

Temperature

Thanks to the thermal pad it's a little tough to read but what we have is the Marvell 88SS9187 controller.
by Legit Reviews (Jun, 2013)
There are thermal pads on most of the main components that you can see still stuck on in some places.
by Legit Reviews (Jun, 2013)
Performance will be throttled in the event junction temperature of critical components is measured to be exceeding the maximum allowable for the product.

Capacity

The 120GB drive has only four modules, each 32GB in capacity.
by Legit Reviews (Jun, 2013)
The 120GB drive has a Samsung cache with part number K4B4G1646B-HCK0 and is 128MB in capacity.

Interface

For the SanDisk Extreme II Series drives, the readout on CrystalDiskInfo 5.2.0 shows that both NCQ and S.M.A.R.T. are enabled, as well as TRIM and the interface is confirmed at SATA III (6Gbps).
by Legit Reviews (Jun, 2013)

Reliability

The smaller lithography flash requires more error correction and generally has lower endurance which the controller needs to handle but the drives have a 2,000,000 MTBF rating.
