200 GB SATA laptop drive
The Toshiba MK2035GSS is a 200 GB, 2.5-inch hard drive built for notebooks that need basic storage capacity. It uses second-generation Perpendicular Magnetic Recording combined with Tunnel Magneto-resistive head technology. The SATA 1.5 Gb/s interface and 8 MB cache provide straightforward data transfer for everyday computing tasks.
4200 RPM thermals and power
Spinning at 4200 RPM, the drive runs with less vibration and lower power consumption than faster-spinning alternatives. Average seek time is 12 ms and average latency is 5.55 ms. The 300000-hour MTTF rating reflects the design focus on reliability for mobile use.
Fits 9.5 mm bays
The 2.5-inch form factor measures 9.5 mm in height, matching the standard drive bay in most laptops of its era. A bare SATA 1.5 Gb/s connection is all that is required; no additional cables or adapters are needed. This leaves other expansion slots free for memory or wireless upgrades.

Questions about this item
How is the 2.5" SATA drive installed in a laptop, and which step is often missed?
Slide the drive into the 2.5" bay, connect the SATA 1.5Gb/s data and power cables, then secure it with the caddy screws; the step often missed is fastening the caddy so the drive cannot shift.
What maintenance or replacement will the 4200 RPM drive need later?
The 300000 MTTF hours rating indicates long life, but mechanical wear will eventually require a full drive replacement; no user-serviceable parts exist inside.
What limit appears first on the 200GB drive during sustained use?
The 1.5Gb/s SATA interface caps sustained throughput at 150MB/s, so the bus saturates before the 8MB cache or 12ms seek time become bottlenecks.
