With a full 256GB of user capacity and a price less than $200, the Transcend SSD720 is an appealing product. Transcend didn't hit this price point by eliminating the goodies either. You get a full accessory package that includes several software tools that make your migration to SSD performance easier.
To date there are only a couple of manufacturers offering SandForce SF-2281 with the 0-provisioning programming. ADATA has a couple of products and now Transcend. Only one of these companies has released working TRIM on its drives and that comes from Transcend and not ADATA. Without the spare area, performance can get to a crawl without TRIM working and your drive filled to high levels, over 80% of the NAND full. TRIM helps clean up that small amount of unused flash to keep the write speeds high. For most power users I don't think the extra 7% of user space is a big deal since most of us don't fill our SSDs to the brink, but it's always nice to have the extra space for trips or other occasions when you might pile movies or music on the drive while away from home. I tend to do that quite a bit for trips when I know I'll be in a hotel room without any music for hours at a time.
I think Transcend did a good job with pricing. The 256GB SSD720 we looked at today currently sells for less than $200 in the US and is available all over the world for less than $1 per GB. All four capacity sizes offer a really good value, but none no more than the 512GB size that comes in at less than $400.
Transcend didn't skimp on the accessory package either. We've seen other companies hit really good price points, like SanDisk's Extreme SSD, but many of those products don't ship with any accessories at all. The Transcend SSD720 ships with a desktop adapter bracket and a nice manual, but the real value comes from their software library that's found on its website.
We really like this Transcend drive for its well rounded approach that combines high performance, innovative programming for the flash management and the accessory package. Transcend also has the TRIM fixing firmware available so your drive will keep performing well in the long term and not fall into a steady state with lower performance.
