Hard Drive Kingston KC600 256 GB SSD

256 GB SSD. 3D TLC NAND. SMI SM2259 Controller. SATA III 6 Gb/s. 550 MB/s Read. 500 MB/s Write. AES-XTS 256-bit. 2.5". 6g. 0°–70°C. Desktop PC, Laptop & PC/Notebook. The Kingston KC600 Internal SATA SSD.

The Kingston KC600 256 GB is a 2.5" internal SATA III SSD with 3D TLC NAND, SMI SM2259 controller, 550 MB/s sequential read, 500 MB/s sequential write, 6 Gb/s SATA III data transfer, AES-XTS 256-bit hardware encryption, mSATA and SATA III connectivity, USB x3 compatibility, 93 x 50.5 mm dimensions at 0.5 cm height, 6 g weight, 0°–70°C operating temperature range, and Multicolour PCB. Compatible with Desktop PC, Laptop and PC/Notebook. The SMI SM2259 controller pairs with 3D TLC NAND and an onboard DRAM cache for consistent 550 MB/s read performance across the full 256 GB capacity range.

SMI SM2259 Controller + 3D TLC NAND + 550 MB/s Read + AES-XTS 256-bit + SATA III 6 Gb/s + 6g Ultra-Light: The Six Kingston KC600 Specifications That Define Its Performance, Security and Physical Profile.

The SMI SM2259 controller with 3D TLC NAND is Silicon Motion’s proven SATA SSD controller paired with vertically stacked triple-level cell NAND — the SM2259 managing the NAND wear levelling, error correction, garbage collection and DRAM cache address mapping that sustain 550 MB/s read and 500 MB/s write across the full 256 GB capacity range without the performance inconsistency that DRAM-less SATA SSD designs produce when the SLC write buffer fills during sustained write workloads. The SM2259 controller’s LDPC error correction extends the effective 3D TLC NAND endurance beyond the raw cell endurance rating — the error correction engine recovering NAND cell errors before they become data integrity events, contributing to the drive’s rated endurance and the five-year warranty Kingston provides on every KC600 unit. The AES-XTS 256-bit hardware encryption implements the XTS cipher mode that the TCG Opal 2.0 and IEEE 1667 enterprise security standards specify — AES-XTS being the encryption mode that storage security frameworks require rather than AES-CBC, making the KC600 compatible with eDrive BitLocker hardware encryption on Windows 10 and Windows 11 without the software encryption performance overhead that BitLocker software mode imposes on the CPU. The 6 Gb/s SATA III interface with mSATA and SATA connectivity operates at 550 MB/s read in both standard SATA III 2.5" installations and mSATA slot installations — the KC600 fitting Desktop PC SATA bays, Laptop 2.5" SATA bays, PC/Notebook mSATA slots and external USB enclosures through USB x3 connection for flexible deployment across every compatible storage interface without a separate drive purchase for each form factor. The 6g weight at 93 x 50.5 x 5mm makes the KC600 one of the lightest 2.5" SATA SSDs in its class — the 6g weight and 0.5 cm height fitting the shallow laptop drive bay designs that 7mm-height 2.5" drives target, without the weight addition that heavier SSD enclosure designs impose on laptop total weight.
