The limitations for the widely using for solid-state hard driver

% of readers think this story is Fact. Add your two cents.


India – Perhaps, many of my friends will ask why all of the ordinary notebook would not equipped with the SSD? Because all of us know that the solid-state hard drivers have more benefits than the traditional hard disks such as the Server hard disk drive and SAS hard disk drive. Today, the best seller for the Server hard disk drives such as the SATA hard disk drive and FC hard disk drive would tell you why the SSD could not be used for widely range. Their website is

The limitations for SSD are at variety of ways. First, the cost is too high. The price of per MB of the Solid state drive is relatively high. Nowadays, the SSD technology is not mature and the cost for memory chips is a little a bit higher and the production yield is low. So, these factors lead to that the solid-state hard drive prices are much higher than the mechanical hard disk. We could search for some solid-state drive such as the 128G SCSI hard disk drive which has been priced at 257 USD. The price of a 128G SSD is up to 500 dollars. So we could find that the cost for the SSD is much higher than the traditional hard disk such as the SUN Hard Drive, EMC Hard Drive and HP Hard Drive.
The other disadvantage for the SSD is that the capacity for the SSD is generally small.

Nowadays, we could find that the capacity of the SSD is from 64G to 512G as opposed to mechanical hard disk, it is a small number. However, the price for a 512GB solid-state hard drive is 3,000 RMB which is close to the price of an entry-notebook. If the solid-state drive wants to achieve large capacity, you can increase the number of flash memory chips. On the other hand, we need to enhance the capacity of a single block of flash memory chips. But the former idea for the number of the flash memory chips cannot be unlimited upgrade. Solid state drive is clearly not regarded as the main storage medium for data storage. For the friends who have the requirements to the provision, you should use the movable hard disks such as the IBM hard disk drive Server Memory to alleviate the pressing.

The third point is about the stability. The working life of the flash memory chip is far below the mechanical hard. Nowadays, the flash memory chip could be divided into two categories which are SLC and MLC flash memory chips. The SLC can only withstand 100,000 times write. The cheap MLC which has been widely used in the U disk, flash memory card is only exposed to a mere 10,000 writing times. The 10000 times write life is suitable for these temporary equipments such as U disk, MP3 or digital cameras but for the solid-state drive is clearly not allowed.
