Kingshark 256GB SSD SATA III mSATA
The 256GB mSATA drive hits 570 MB/s reads and 500 MB/s writes over SATA III, with TLC NAND and a 380 TBW endurance rating backed by a 3-year warranty. It also draws just 0.3W at idle, which helps extend laptop battery life, and includes TRIM, garbage collection, and ECC for data integrity. This is a practical pick for budget-minded users upgrading an older laptop or mini PC that only has an mSATA slot.
