Corsair Force LE 480GB TLC SSD Review (PN# CSSD-F480GBLEB)

Corsair Force LE 480GB TLC SSD

The Corsair Force LE 480GB TLC SSD sports a Phison PS3110-S10 controller and Toshiba’s 15nm TLC NAND flash, a formula we’ve seen on other drives from vendors that don’t produce their own controllers and NAND. Set as an entry level drive series with less expensive TLC (Triple Level Cell), the Corsair Force LE 480GB comes in at a bargain price of . SSD’s are becoming a more attractive alternative to platter drives, and with high storage capacities at lower prices, we can heartily recommend swapping the old platter drive out for an SSD and relegating the old platter drive to data storage or non-speed gobbling applications. All of the different sizes of Corsair Force LE offer the same speeds at read (560 MB/s) and write (530 MB/s), but as the size increases, so do the attainable IOPS.

Here’s the breakdown on IOPS vs storage capacity:

IOPS/Capacity Corsair Force LE Drive Series

  • 240GB – 83,000 random read IOPS and 40,000 random write IOPS
  • 480GB – 83,000 random read IOPS and 55,000 random write IOPS
  • 960GB – 85,000 random read IOPS and 60,000 random write IOPS

The TLC (Triple Level Cell) portion of the drive deserves some explanation:

SLC (Single Level Cell) NAND stores one Bit a 1 or a 0 per cell

MLC (Multi Level Cell) NAND stores two Bits a 1 and a 0 or any combination of both per cell

TLC (Triple Level Cell) NAND stores three Bits again 1 and 0 in any combination

The price of the different NAND flash types corresponds with its reliability and performance; SLC provides the highest price and reliability, MLC the second most expensive and second most reliable, with TLC being the least expensive. Moving from SLC (Enterprize Class) to MLC results in 10 – 20 times less Read/Write cycles per cell and TLC has a corresponding drop in write life.

Corsair Warranties the Force LE series drives at 3 years and/or the stated Endurance Life:

Endurance Specifications

  • 240GB – 60 terabytes written (TBW)
  • 480GB – 120 TBW
  • 960GB – 240 TBW

Now we know the advantages and disadvantages of the different types of NAND as far as endurance goes and how the storage on each type handles data but there are other considerations. SLC and MLC thus far tend to bog down on compressed format data (Images, Music, Video and other compression schemes) and performance will bog down slowing the operation of the drive. The TLC drives don’t utilize compression to make operations faster and require a stronger controller like the Phison PS3110-S10 controller. What does that mean to us as consumers you ask? When a TLC drive hits compressed data it doesn’t try to re-compress it to make speeds faster it takes it and shoves it through the data pipe and doesn’t slow down.

On the flipside of the equation, SLC drives are recommended for enterprise-class operations, data farms, servers, and high read/write operations. eMLC (Enterprise MLC) is also suitable for lighter heavy data intensive operations. MLC is suitable for light business and consumer level including operating systems but not really recommended for mission critical situations. TLC is recommended for consumer level (non-mission critical) operations and some reporting sources say not for operating systems and data-intensive users. Thus far we have had no trouble with TLC drives running operating systems as the primary drive, but it is worth noting that if you are running mission critical OS or programs you may want to spring for an MLC or eMLC drive.

Ordinary end users shouldn’t be put off by TLC, and with expected wear and tear your TLC drive should give you years of service.
