Flash based storage can really wake up an older PC due khổng lồ it’s massive increase in speed và decrease in seek time as compared it its rotating disk counter part. As the price of flash memory continues to lớn drop, we start khổng lồ see SSD’s prices per gigabyte creep ever closer lớn mechanical hard drive’s price per gigabyte. Khổng lồ further drive the price of NAND (or flash) memory down, TLC (Tri Cell level) was brought khổng lồ market. TLC based chips allow more data lớn be stored in the same physical are of silicon. Think of SLC (Single cấp độ Cell) as 1x, MLC (Multi cấp độ Cell) as 2x, and TLC as 3x, as MCL can store 2x the data of SLC in a given area & TLC can store 3x the data as SLC in a given area. All that sounds great however, there are some trade-offs. Plextor demoed the M7V TLC SSD at CES & is starting lớn hit the retail shelves now.
