Dell 2TB 5400 RPM SATA 6Gb/s 2.5 Inch 7mm Internal Notebook Hard Drive Seagate ST2000LM007 0DD2XK

Key Features

• This is a 2.5-inch 7 mm internal notebook hard drive. It is NOT a PowerEdge hot-plug server drive.
• 2 TB capacity at 5400 RPM. It is not a 7200 RPM drive.
• Seagate Mobile HDD ST2000LM007, catalogued by Dell parts vendors under Dell part DD2XK and 0DD2XK, Seagate part 1R8174.
• SATA 6.0 Gb/s (SATA3) interface.
• 128 MB cache.
• Ships as a bare drive: no carrier, no caddy, no bracket and no rails.
• No PowerEdge drive carrier accepts a 7 mm notebook drive, so this part cannot be fitted to a server bay.
• No qualified-system list is published by Dell or by Seagate for this part number, so none is printed here.

Not a server drive

The most important thing on this listing is what this part is not. It is a bare 2.5-inch notebook hard drive at a 7 mm z-height, and it is not a PowerEdge drive in any sense. It is not hot-plug, it does not come in a carrier, and no PowerEdge carrier will accept a 7 mm drive, so it cannot be pushed into a server bay whatever the bay's size suggests. Our own live title calls it a small form factor workstation drive, and in PowerEdge language small form factor means a 2.5-inch hot-plug server drive in a caddy. That reading is wrong here and it is corrected on this page, because a buyer who orders it for a server has bought the wrong part.

5400 RPM, not 7200

The drive spins at 5400 RPM. Our live title says 7200 RPM, and that is the single most searched specification on a hard drive listing, so it is worth being unambiguous: both the Dell parts vendors cataloguing this DP/N and Seagate's own model designation put the ST2000LM007 at 5400 RPM. The rest of the specification is 2 TB of capacity, a SATA 6.0 Gb/s interface and a 128 MB cache. If the requirement is a 7200 RPM drive, this part number does not meet it and no firmware setting changes that. If the requirement is capacity per pound in a notebook bay, 5400 RPM at 2 TB in a 7 mm height is what this part is for.

It ships bare

This is the drive and nothing else. There is no caddy, no bracket, no adapter and no mounting screws recorded against the part, and no source states otherwise. In a notebook that is normal: the machine's own bracket is reused. It is worth stating on a server-parts shelf because the expectation there is the opposite, and because the omission is not recoverable by ordering a Dell carrier afterwards. Sector format is another thing this listing does not state. One secondary vendor page describes the drive as 512e, no Dell or Seagate page confirms it for this part number, and a single source is not enough to publish against a storage specification.

Compatibility not published

Neither Dell nor Seagate publishes a qualified-system list for this DP/N. One vendor page carries a long list of Latitude, Inspiron, XPS, Vostro, Alienware and Precision mobile systems, and that list appears on exactly one page with no corroboration anywhere, so it is not repeated here as if it were Dell's. What can be said is the shape of the thing: it is a 7 mm 2.5-inch SATA drive, so it fits a bay built for a 7 mm 2.5-inch SATA drive, and a bay built around a 9.5 mm drive should be checked before ordering. Send us the system model and we will read the machine's own service manual before shipping.

Where it fits

This is a capacity upgrade or a like-for-like replacement for a notebook or a small-form-factor machine that already runs a 2.5-inch SATA drive: a bulk storage volume in a mobile workstation, a second drive in a bay that has one, or a straight swap for a failed unit. It is not a boot drive for anything modern, where an NVMe SSD does the job several times over, and it is not a server drive at all. Buy it where the requirement is 2 TB of mechanical capacity in a 7 mm bay, and check the bay height first.
