Transcend SSD320 & SSD720 (256GB) Review
by Kristian Vättö on January 25, 2013 11:31 AM ESTPerformance vs. Transfer Size
ATTO offers a quick way to measure performance at varying transfer sizes. While real world IOs mainly concetrate on IO sizes of 4KB, 8KB and 128KB, it's important to get a big picture of the drive's performance. There is once again hardly anything surprising, both the SSD320 and SSD720 are on par with Intel's SSD 335. Overall the SF-2281 is starting to show its age as especially in read performance Samsung's SSD 840 Pro and OCZ's Vector are substantially ahead.

For a second I thought they were 320G and 720G drives.Azurael - Friday, January 25, 2013 - link
So what's the difference between a Sandisk Extreme SSD and a Transcend SSD720? How many more identical SSDs can the market support?Flying Goat - Friday, January 25, 2013 - link
If you tried to skip the drives over a lake, you'd find that one was most likely designed with aerodynamics in mind, while the other was not. Sadly, we're just never going to see the sort of truly complete feature comparison at AnandTech that covers that sort of thing. :)gammaray - Friday, January 25, 2013 - link
i dont know, but i got the SanDisk extreme 240gb home and its ultra fast and paid 160$ on sale for it :Dembzyk - Sunday, January 27, 2013 - link

The Transcend SSD720 256GB achieves a busy time of just over half that of the Samsung SSD 840 Pro 256GB, and it's missing a decimal place.This seems highly suspect.

Oh, you're right, there was a typo. It should've been 362 instead of 162. Fixed! :-)iwod - Friday, January 25, 2013 - link
SSD1st Gen - SATA ; Response Time Reduction Compared to HDD
2nd Gen - SATA II; Higher Seq Read Write
3rd Gen - SATA II; Better Random IO
4th Gen - SATA III; Overall Improvement to both Seq and Random
5th Gen? I think Next Gen we need SATA Express and something similar to Intel's Consistent I/O Performance.

Eh, there's still a fair amount of head room on the SATA 3 interface. Wouldn't expect PCIe to become the norm for at least another two generations.Tech-Curious - Saturday, January 26, 2013 - link
Sorry, misread your comment, iwod. Still, even if sequential speeds remain more or less stagnant, there's a lot of room left to improve random read/write with SATA 3.
