Hardware-encrypted SATA SSD
The SanDisk X300s SD7UB2Q-512G-1122 is a 2.5-inch internal solid-state drive with 512GB capacity. It connects through a SATA III 6Gb/s interface and uses MLC NAND memory. Hardware-based 256-bit AES encryption meets TCG Opal and Microsoft Encrypted Hard Drive standards. Dynamic thermal throttling and DevSleep low-power mode support Microsoft InstantGo.
Suited for secured laptop upgrades
This drive suits laptops and desktops that require full-disk encryption without software overhead. The 2.5-inch form factor fits standard drive bays and caddies. Systems limited to SATA II ports will not reach the rated 520 MBps read or 460 MBps write speeds. Workloads needing sustained throughput above those figures should consider faster interfaces.
512GB MLC capacity with 256-bit AES
The single specification that decides fit is the 512GB MLC capacity combined with hardware 256-bit AES encryption. It delivers up to 96,000 random read IOPS and 80,000 random write IOPS with 55µs read and 65µs write latency. MTTF is rated up to 2,000,000 hours and endurance exceeds 80 terabytes written.

Questions about this item
What do I need in my system for the 2.5" SATA III 512GB drive to work?
A free 2.5" drive bay or bracket, a SATA data cable and a SATA power connector from the power supply are required for the SD7UB2Q-512G-1122 to operate.
Will the SATA III 6Gb/s interface run at full speed on an older SATA II motherboard port?
The drive is backward compatible with SATA II 3Gb/s ports, though sequential read and write will be limited to the older port's maximum throughput.
How can I confirm the 256-bit AES hardware encryption is active after installation?
Use a TCG Opal management tool or Windows BitLocker to take ownership of the drive; the software will show the self-encrypting drive as hardware-encrypted when the feature is enabled.
