This is what we need:
"With E20’s built-in DDR2 DRAM Cache Memory, even during continuous intensive-write situations, computers shall lag no more," the company said. "This feature not only enhances SSD’s read and write performances, it also extends SSD’s lifespan."
Sounds like a great drive but likely overpriced.
I think I might buy the Micro Center 64GB SSD, it uses the SandForce 1200 chips which allow for some of the fastest SSD speeds available today.
(It's only $99) Although I'd certainly like a higher capacity drive for the same price...
Yeah, the effect of the DDR is the big mystery here. Will it really work to improve things?
You would think it should help with responsiveness on short-term intensive tasks that saturate the ability of the NAND controller and NAND chips to respond. It's basically adding another layer of cache that should be faster than the (main) NAND chips.
If the DRAM controller has good logic and guesses correctly what the user needs to get from the drive most of the time, then this might be a winner.
On the other hand, if they are just out to say that they were the first to add DRAM cache, but do a sloppy implementation of it, then it will be useless.
This is what killed the first hybrid drives (sloppy implementation with too little NAND cache) and what makes the current Seagate Momentus XT hybrid drives a success, with good controller logic implementation with enough NAND cache to make a difference.
I hope Silicon Power gets the technology right and also offers the drives at a reasonable price. A premium for better performance is okay, but a steep premium would be a mistake in the ever more competitive and price sensitive SSD market.
1: What is the MLC count?
2: How many ECC bits? (will also tell me the MLC count)
3: What is the page and block size?
4: Is TRIM cmd supported from within VMs (the host OS will not support TRIM on VM image files)
5: Is write performance rate sustained? (large file write filling cache & not enough empty cells)
6: What is the average # of erase/write cycles before a cell fails?
7: How much $$
