The Lenovo PM1655 1.60 TB SAS SSD is a next-generation enterprise-grade solid-state drive optimized for mixed-use workloads in ThinkSystem servers. This 3.5-inch internal drive leverages a 24Gb/s SAS interface to deliver high throughput, low latency, and consistent performance across a broad range of applications—from OLTP databases to virtualized environments and analytics. As the successor to the PM1645a, the PM1655 family provides improved performance, efficiency, and endurance, while maintaining enterprise-class reliability and compatibility with modern data center backplanes.

  • Blazing-fast SAS 24Gb/s performance for mixed workloads — This PM1655 drive is built for high-throughput data centers, delivering strong sequential throughput and low latency under diverse I/O patterns. The 24Gb/s SAS interface paired with efficient flash management minimizes queue depth delays, reduces I/O bottlenecks, and helps your ThinkSystem servers sustain peak performance during heavy OLTP, virtualization, and analytics workloads. With robust error detection and advanced wear-leveling, you get consistent responsiveness that servers demand for mission-critical operations.
  • Enterprise-grade reliability for mixed-use environments — Designed for continuous operation in data-center backplanes, the PM1655 provides endurance and data integrity features that keep workloads running smoothly. Ideal for mixed-use scenarios that combine transactional databases, virtual machines, and data analytics, this drive maintains steady performance with predictable latency and strong MTBF characteristics typical of Lenovo ThinkSystem storage solutions.
  • Scalable capacity and flexible deployment — Available in capacities starting at 1.60 TB with PM1655 family options reaching up to 6.4 TB, these drives offer scalable storage density to fit dense servers and storage arrays. The 3.5" internal form factor and SAS interface support seamless integration into existing ThinkSystem backplanes, enabling easy expansion without rewriting your storage topology. In addition, the drives are designed for easy hot-swapping in supported systems to minimize downtime.
  • Optimized for ThinkSystem integration and management — These SAS SSDs are purpose-built to work with Lenovo ThinkSystem servers and management tools, enabling streamlined deployment, firmware updates, and health monitoring. Administrators benefit from consistent drive behavior across the fleet, standardized firmware, and robust warranty coverage backed by Lenovo support. This translates to simplified IT operations and faster time-to-value for storage-intensive workloads.
  • Energy-efficient performance for dense data centers — Despite delivering enterprise-grade speed, the PM1655 is engineered with power-efficient flash management to help lower overall data-center energy consumption. Lower active power during peak performance periods, combined with effective idle power characteristics, contributes to cooler operation, reduced cooling costs, and a smaller total cost of ownership for mixed-use deployments.

Engaging and Fun, But Lacks Durability for Strong-Gripped Dogs
Color: Green
The internal mechanism of this toy works very well, and the ball’s movement immediately caught the attention of my Boxer pup. He was absolutely fascinated and spent hours each day playing with it. However, while the toy’s design is engaging, the durability of the exterior leaves much to be desired—especially for dogs who tend to pick things up with a firm grip. We didn’t know what to expect since our pup hadn’t previously played with an interactive ball, so we supervised playtime and made sure to store the ball in a safe spot when we couldn’t keep an eye on him. Despite this, the ball didn’t hold up. Our pup wasn’t intentionally chewing it. He simply carried the ball in his mouth when we moved downstairs or to another room, yet the grip while he carried the ball caused significant damage to the exterior. Within about a week of regular use (approximately 40 hours in total), the ball’s outer layer became deeply gouged by his teeth. To clarify, my pup wasn’t biting down hard or trying to destroy it, but his natural grip while carrying the ball left deep grooves in the surface. In just days, these gouges made the exterior sharp to the touch and compromised the structure. By the end of the week, we couldn’t screw the cover back together after removing it to recharge the ball, which made it unusable. And I was dismayed that there aren’t replacements readily available. Overall, my pup absolutely loved this toy — it was engaging and kept him entertained for hours. However, if your dog has a strong grip or frequently carries toys in their mouth, this may not hold up as well as expected. It’s a great concept but needs a more durable outer layer and replacement hard covers to make it a long-term investment.

My dog loves this ball
Color: Green
The battery on this lasts forever. The random on/off motion and when it gets touched inducing motion just keeps my dog guessing and occupied for a long time. My dog's tail is wagging the whole time.

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.

Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too. I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.
