I often tell people that SSDs work better with more free space, so anything that increases free space will keep WA lower. The two key ways to expand free space (thereby decreasing WA) are to 1) increase over provisioning and 2) keep more storage space free (if you have TRIM support).
Flash performance and endurance is a tricky subject, and yet Samsung's flagship, the SSD 840 Pro remains one of the best in both categories.
Having aced its attempts at speed and durability, Samsung seems focused on solving flash's biggest sacrifices: size and affordability. Its new SSD 840 Evo lineup has models spanning from 120GB to 1TB, with the largest costing only $0.65 per gigabyte thanks to its use of TLC NAND.
I think we need to remember that as engineers and technologists. We get caught up in the short-term tactical delivery of technology. We don’t see the sometimes immense ripples in society from our work - even years later.
Lian Li's D8000 is also on the purposely huge HPTX form factor. As a point of reference, a standard ATX mid-tower supporting seven expansion slots generally has a 60L capacity while the big Cubitek HPTX-ICE and Lian Li PC-V2120 tout capacities of 79L and 88L.
With a capacity of 145L, the D8000 shatters that paradigm, offering 140% more room than a standard ATX case, which makes sense since the D8000 is essentially two full tower cases fused together.
The new SanDisk Extreme II features an in-house developed firmware which helps to set it apart from other SSDs using the same controller. Also of note, the second generation Extreme series has dumped the SandForce controller in favor of the new Marvell 88SS9187, the same controller used by the Crucial M500.
SanDisk is pricing the 240GB Extreme II competitively fetching around $230, right on target with the Vertex 450 and also in the neighborhood of the Samsung 840 Pro, which will remain a secondary focus throughout this review.
A number of years ago, the storage industry got together and developed a solution between the OS and the SSD by creating a new SATA command called TRIM. It is not a command that forces the SSD to immediately erase data like some people believe.
The battle between the OCZ Vector and the Samsung SSD 840 Pro has been closely contested ever since the Indilinx-based drive arrived late last year, though when push comes to shove OCZ could be on the losing end.
Meet the Vertex 450, OCZ's latest addition to the Vertex SSD series based on a slightly modified version of the Barefoot 3 controller that is designed to be more cost effective. So how does the new Vertex drive fare against the best SSDs in the market including OCZ's own?
It’s worth pointing out that almost all the "magic" that has been developed around flash was already scoped out in 2007. It just takes a while for a whole new industry to mature. Individual die capacity increased, meaning fewer die are needed for a solution – and that means less parallel bandwidth for data transfer…
