What you're getting

PNY CS900 is a 2.5 inch SATA III solid-state drive family aimed at straightforward upgrades from spinning disks on desktops and laptops that still rely on the SATA bus.

Retail listings quote capacity-dependent sequential performance, with this line commonly positioned up to about 550 MB/s reads and about 500 to 530 MB/s writes depending on the SKU you choose.

Most listings ship the bare drive, while the upgrade-kit SKU adds a USB-to-SATA transfer cable and bundled cloning-oriented software so you can migrate from an old drive without buying accessories separately.

Because it uses the familiar SATA power and data connectors, CS900 fits many older enclosures and notebooks where NVMe slots are unavailable or already occupied.

Using your supplied snapshot prices, cost per terabyte trends from roughly two hundred twenty dollars at five hundred gigabytes down toward about one hundred forty-five dollars at two terabytes before coupons. SATA SSD promos move quickly, so confirm the live cart price on each listing.

Features
