Intel SSDSC2KB019T801 1.92TB SATA Enterprise SSD: specs and who it suits

The Intel SSDSC2KB019T801 is a 1.92TB solid-state drive built for servers and storage arrays. It uses the common 2.5-inch SATA format, so it can slot into many existing drive bays as a faster alternative to spinning hard disks. This page explains what its figures mean and what to confirm before fitting one.

What "enterprise" means for an SSD

Enterprise drives are designed for systems that run around the clock, often under mixed read and write loads. Intel describes this model as an enterprise server SSD with TLC NAND, which stores three bits in each flash cell. TLC is a widely used balance between capacity and endurance. The drive is listed with a mean time between failures (MTBF) of 2 million hours. MTBF is a statistical reliability estimate across many drives, not a promise about any single unit, but it is a common way to compare drives designed for continuous use.

Speed: sequential, random and latency

Intel lists sequential reads of up to 560 MB/s and sequential writes of up to 510 MB/s. Those numbers sit close to the practical ceiling of the SATA 6Gb/s interface, which is why most SATA SSDs look similar here. Sequential speed matters for large file copies, backups and streaming data.

Random performance is often more relevant for servers. Intel rates the drive at 97,000 IOPS for random reads and 35,500 IOPS for random writes across the full drive span. IOPS means input/output operations per second, and it describes how many small reads or writes the drive can handle. Read latency is listed at 36 µs and write latency at 37 µs. Low, consistent latency generally helps databases, virtual machines and file servers feel responsive.

Power and physical durability

The drive is listed at 3.2 W active and 1.1 W idle. In a rack with many drives, those small figures add up, and lower draw usually means less heat to remove. The thickness is 7.0 mm, the standard for 2.5-inch SATA drives. Intel also lists operating vibration of 2.17G and shock tolerance of 1000G at 0.5 ms, both operating and non-operating, which gives an idea of how well it copes with the knocks of handling and transport.

Where it fits

Intel states that the drive is compatible with servers and arrays that accept 2.5-inch, 7 mm SATA drives. It suits someone replacing or adding capacity in such a system, or building a storage tier that needs steadier performance than a hard disk offers. It is not an NVMe drive, so it will not match the speeds of PCIe models, and it will not fit an M.2 slot.

What to check before you buy

• Confirm your server, array or workstation has 2.5-inch, 7 mm SATA bays, and whether it needs a drive tray or caddy, which usually isn't included with a bare drive.
• Check the manufacturer's compatibility list for your server or RAID controller, since some systems restrict which drives they accept.
• Make sure the interface is SATA3 (6Gb/s) on your controller; older ports will limit speed.
• Look at your workload. Heavy, constant writes call for attention to the endurance figures in the manufacturer's documentation.
• If you plan to mix it with other drives in an array, check that capacities and performance suit the RAID level you use.
• Read the warranty terms and firmware update options on the manufacturer's site.

The short version

• 1.92TB, 2.5-inch, 7 mm SATA3 enterprise SSD with TLC NAND.
• Up to 560 MB/s sequential reads and 510 MB/s writes; 97,000 random read and 35,500 random write IOPS.
• Listed latency of 36 µs for reads and 37 µs for writes, with a 2-million-hour MTBF.
• 3.2 W active and 1.1 W idle power draw.
• Built for servers and arrays that accept 2.5-inch SATA drives; not for M.2 or NVMe slots.
