Technology of solid state hard disk has not been company level to use hard disk of ready-made solid state (SSD) it is a technology that has an outlook greatly, nevertheless, the analyst expresses, be in high-end enterprise or on the application of ” of “ memory class, this one technology still may do not have ready-made. Bob Merritt of analyst of Convergent Semiconductors research organization expresses, the solid state hard disk that is based on NAND may store in high-end enterprise and “ the be rebuffed on class ” application. Compare with NAND photograph, change storage technology (Phase-change) remember body technology with resistor (Resistive Memory) , meet more hopeful on storage equipment applying it seems that. Be based on NAND to show the solid state hard disk that put, its are born the purpose is to be in certain applying, be like mobile PC, hard disk drive can be replaced on notebook computer and enterprise server. But photograph of solid state hard disk is more costlier than hard disk, both the price between is far apart.

Additional, this one market just also starts. Solid state hard disk is in mobile PC, “ still is belonged to on high-end notebook computer and server application the level that ability of small carry on one's shoulder shows ” of pointed pointed horn. Merritt says: “ goes, we use magnetic medium on memory data, DRAM and SRAM. All these technologies are writing what go up to be considered as 0 loss with erasure data, because this is being brushed,be boundless on write cycle time. ”He says: “ does not pass, NAND has a foregone loss process. Theoretic, of SLC brush keep life number 10 thousand times, MLC is in thousands of the left and right sides. So we want the function need of the applied process of careful consideration, decide whether applied SSD is appropriate again next. ”Merritt says: In the display of higher administrative levels that “ calls ” of “ company level from people, OEM manufacturer can decide a few application that do not need to brush write cycle time in great quantities, NAND SSD can answer those primary application easily. ”According to the report, include IBM and SanDisk inside a few companies, “ does not believe NAND can apply on the company level memory that needs higher reliability. ”Merritt says.

Be located in solid state hard disk this kind of circumstance surely is a mistake likewise. He says: Hard disk of “ solid state is one is having important and positive effect and the product that enormous size promotes latent capacity. The risk of semiconductor company is by OEM square, or let final user extremely likely assume. Return in solid state hard disk crudely when throw its application, can let the market finally think “ of solid state hard disk is fluky only ” . From the perfect angle that assures a technology for, I feel, the practice of responsibility of complete marry again is premature to say still to semiconductor company. ”So what is conclusion? Solid state hard disk is the perfect choice of a few application, but not all. To high-end enterprise character, use NAND shows the solid state hard disk that retains a base what to will not be damaged.
