We have already tested SSDs with second-generation SandForce controllers and 24nm Toggle Mode flash memory before and today’s testing of Silicon Power Velox V60 and Transcend SSD720 drives didn’t produce any surprises since they have the same hardware platform. These SSDs are somewhat faster than popular SandForce-based drives with 25nm flash and synchronous ONFI interface, but often find themselves lagging behind the Intel SSD 330 which features exclusive firmware. It means that the Velox X60 and SSD720 are typical SSDs with SF-2281 controller which have all the highs and lows of such products.
The nonstandard 128GB capacity of the Transcend SSD720 didn’t change anything. The disabled RAISE technology didn’t affect the drive’s performance much. SandForce-based SSDs with a reserved space of 7% rather than 13% do not offer any benefits other than the extra user-accessible storage. Some people may worry about potential reduction in their reliability, but we don’t share such apprehensions because today’s MLC NAND flash is high quality.
Considering the respectable age of the second-generation SandForce controller and the fact that the capacity of 120/128 GB isn’t optimal for it, we must admit that the Silicon Power Velox V60 120GB and the Transcend SSD720 128GB can hardly be counted among the most interesting solutions today. The former is especially poor due to its old firmware with TRIM implementation flaws. The Transcend SSD720 is better in this respect. It has up-to-date firmware and useful accompanying software. The price factor must also be taken into account, though. Priced affordably, these SSDs seem to be quite competitive in the mainstream market segment. They can be recommended for all-purpose desktop and mobile computers.
Some time ago we started to fill in a summary table with test results of various SSDs. It contains basic hardware information about the tested SSDs and allows to quickly determine the general position of a particular model among its competitors in terms of relative performance.
