Here are all of the models currently in the database for this manufacturer and drive width. Models are sorted into sections by platter density.
Some tips:
All displayed data capacities follow the storage industry's standardized "1 megabyte = 1,000,000 bytes" rule.
All capacity values are rounded: "40GB" and "1.33TB" may actually be 42,646.25[...]MB and 1333.5666[...]GB. Only the manufacturer knows the exact capacity per platter.
The total capacity of each individual model is shown beside each model number.
A platter-head ratio is shown next to the total capacity tag in brackets. It works very simply: a (3/6) ratio indicates three disks and six read/write heads. Models that "waste" a substantial amount of their actual total capacity in order to fit into certain capacity brackets (such as a 320GB unit based on one 500GB platter and two heads) are marked accordingly as [short-stroked].
Miscellaneous details of possible interest are mentioned at my discretion.
Assume that all models are 9.5mm-thick except when tagged otherwise.
Seagate bought out Samsung's HDD division at the end of 2011. Shortly after, various SpinPoint M7(E) and M8 models began to circulate with Seagate-style model numbers (prefixed with "ST"), which I've added to this page adjacent to the Samsung M/Ns of models they are otherwise identical to. The few new lineups with distinct Samsung-specific characteristics that have come out since the buyout can also be found on this page.

30GB/platter Section (all drives under here use platters that can hold 30GB of data apiece.)
SpinPoint MC30 (5400RPM, 8MB cache, ATA-100 interface, for industrial/vehicle)
HM031HC 30GB (1/2)
Note: There might be some significant level of architectural DNA shared with the MN40. Even the PCB (without looking at IC part numbers) has the same "M40/MN40" etched into the soldermask.
40GB/platter Section (all drives under here use platters that can hold 40GB of data apiece.)
SpinPoint M40 / MN40 (5400RPM, 8MB cache, ATA-100 interface)

MP0603H 60GB (2/3)
MP0804H 80GB (2/4)
Note: "MN40" is the second revision of the M40. It appears to adopt the architecture of the M60 or M80 while staying with 40GB platters. It can be identified by: "REV. B" appearing on the top label; "MN40" appearing on the smaller label with barcode; "M40/MN40" etched into the PCB soldermask (first revision has "MAGMA" or "M40S" there instead); and a manufacture date of mid-2006 or newer. All of this also applies to the below M40S models (add an "S" where appropriate).
SpinPoint M40S / MN40S (5400RPM, 8MB cache, SATA-150 interface)
HM020GI 20GB (1/1)

HM08HHI 80GB (1/2)
HM12HII 120GB (2/3)
HM16HJI 160GB (2/4)
Note: The flash memory is intended for Windows Vista's ReadyDrive, and does nothing in particular otherwise. A datasheet for an MH6 line with double the platter and NAND capacity can be found, but actual drives don't appear to have reached production.
125GB/platter Section (all drives under here use platters that can hold 125GB of data apiece.)
SpinPoint M5S (5400RPM, 8MB cache, SATA-150 interface)

HM161JJ 160GB (2/4 [short-stroked])
HM201JJ 200GB (2/4 [short-stroked])
HM251JJ 250GB (2/4)
Note: An MP100 model family with (wait for it) 100GB platters was supposed to arrive in June of 2007, but the MP2s came out instead around the same time the next year.
160GB/platter Section (all drives under here use platters that can hold 160GB of data apiece.)

HM160HX 160GB (1/2)
HM251JX 250GB (2/4 [short-stroked])
HM320JX 320GB (2/4)
Note: In what would become increasingly common in the years after, these units implement a SATA-to-USB bridge chip right on the PCB. A USB mini-B plug and LED sit where the SATA connector once was, allowing Samsung to decrease the cost of, and streamline, their external HDD products. Restoring a SATA connection should the bridge chip or USB plug fail involves soldering some wires.
167GB/platter Section (all drives under here use platters that can hold 167GB of data apiece.)
SpinPoint M6 / MT1 (5400RPM, 8MB cache, SATA-300 interface)
HM400LI 400GB (3/5 [short-stroked])
HM500LI 500GB (3/6)
Note: Distinctive for being the first laptop drive to cram three platters in without increasing the z-height. These are 9.5mm-thick.
SpinPoint M6 / MT1 (5400RPM, 8MB cache, USB 2.0 interface)
HM500LX 500GB (3/6)

HM750LI 750GB (3/5 [short-stroked])
HM100UI 1TB (3/6)
Note: The successor of the 9.5mm MT1 plays it safe by increasing the thickness.

SpinPoint M10P / Seagate Laptop HDD (5400RPM, 128MB cache, SATA-600 interface, Advanced Format, Shingled Magnetic Recording, 15mm z-height)
ST3000LM016 3TB (4/8 [short-stroked])
ST4000LM016 4TB (5/10)
Note: The product manual lists multiple M/Ns per capacity, and isn't forthcoming on the differences (besides encryption); only the "016" models, which appear the most common, are listed. Drive-managed SMR use in at least the ST4000LM016 (though I wouldn't expect "shingles or not" to be a differentiating factor between the model numbers) is highly likely, given the eerily strong performance of randomized 4K writes in CrystalDiskMark 1000MB (a consistent behaviour of SMR HDDs across manufacturers), along with talk in data recovery forums of a "media cache".
Note 2: As with the D8Xes and M9T(U)s, these came out sometime after the Seagate buyout, and the Samsung branding on the labels is fully replaced by Seagate's in later batches.
