Transcend Introduces Full SLC SSD Lineup
Bohs Hansen / 4 years ago
Transcend revealed their SSD570 almost three months ago and now they’re ready with the full lineup surrounding the SSD570 SLC SSD and with most current form factors. SLC NAND has quite a few advantages over MLC and TLC NAND, but it also comes at a higher price and with less capacity. MLC NAND is used in mainstream and enthusiast drives while TLC NAND is used in the newer budget oriented drives for three times the capacity per chip used over SLC.
But Transcend’s new lineup is full of SLC drives that have the superior performance and reliability. There are normal 2.5-inch slim SSD drives and half sized case-less drives as well as mSATA and M.2 of various sizes. The 2.5-inch, half-slim, and mSATA versions come as both SATA3 and SATA2 drives while the M.2 come in two different lengths, 42 and 80 mm, but both SATA3 models and the default 22mm wide.
SLC NAND has a higher durability than MLC that is found in most consumer products and SLC can withstand up to 50,000 program and erase cycles at the same time as it can perform with up to three times the speed of MLC flash. On top of that comes a lower power consumption and error rates, making these perfect for mission critical applications.
The drives feature all the normal features such as S.M.A.R.T. function to monitor the drives health status, but they also feature more advanced features such as DevSleep. DevSleep is the newest power saving feature that sets the drive into the lowest possible power state. Transcend also added error correction code (ECC) and wear-leveling algorithms to these SLC SSDs. The final feature is necessary when we’re talking mission critical data, and that is the Power Shield function that ensures data integrity in the event of a sudden power loss.
The new line contains the SATA3 SSD570K and SATA2 SSD520 2.5-inch drives, the HSD570 SATA3 and SSD25H-S SATA2 half-slim SSDs. The SATA 2 and SATA3 mSATA SSDs are called MSA520 and MSA570 respectively while the M.2 drives are called MTS870 and MTS470.
