The HDD Platter Capacity Database

This periodically-updated site attempts to keep a record of which hard drive models, both current and discontinued, found in desktops and notebooks, DVRs and cars, but generally with a spindle speed not above 7200 RPM, utilize what capacity of platters, how many platters, and how many read/write heads.

These attributes can be important for several reasons: greater platter density generally allows for higher data throughput performance, but may result in slower seek performance. Meanwhile, fewer disks and actuator arms mean fewer moving parts in the drive to eventually break down, and can decrease the heat and noise output of a drive. I research and collect data from online, as well as from drives that I manage to test in real life, and arrange it all in these lists for you folks to look at.

Anyway, choose which manufacturer made your drive:

• -ExcelStor
• -Fujitsu
• -IBM/Hitachi GST
• -Maxtor
• -Quantum
• -Samsung
• -Seagate
• -Toshiba
• -Western Digital

Note: I try to keep the information updated and accurate, but I don't always get things right. So, here's a disclaimer: the use of this database is at your own risk, and all information in this database should be taken with a pinch of salt. Also, the contents of this database may change at any moment! For best results and minimal heartache, please consult multiple sources other than just this site when searching for hard disk platter-related information.

A lot of the data on this site comes from "logical guessing": working out which platter density a given family of drives uses by, for example, analyzing online benchmark results, and then using simple math to figure out the platter/head counts for each individual model. This is done instead of purchasing a bunch of drives and cracking them open -- by far the most effective way, but also the most expensive and wasteful. These lists were originally created because most of the drive makers had stopped releasing such information to the public. (Some company datasheets -- such as this one for Seagate's Momentus 5400.2 -- do list platter/head counts for each capacity, or at least provide enough related specifications to get there manually. In those cases, I've pulled and/or adapted their information into the lists for convenience.)

In recent years (mainly since ~2009, by my estimation), individual models with multiple possible configurations of platter density, platters, and/or heads have been reaching market, with the only sensible ways to tell the difference being weighing and benching (each with the inconvenient prerequisite of having the individual(s) in question on hand). The manufacturers' reasons for doing this can only be guessed, and not every model is necessarily affected, but the likelihood of a particular model to be sold with such an "alternative" configuration may vary depending on the time it's spent on the market, among other possible variables. Nonetheless, the head/platter counts for newer (from 500GB/platter for 3.5"; 250GB/platter for 2.5") units on the pages, especially, should be considered only as the best-case scenario for those units. Models which received increased scrutiny for this problem will be accompanied in the pages with way(s) to tell their variants apart, while refurbished, recertified, or repaired units of any build date (due to the nature of the makers' restoration process in many cases) should be considered as a lost cause.

That said, if you see any models that aren't listed or that you feel are listed incorrectly, feel free to sound off in either the comments section of the appropriate page or through the Contact form, and I'll see what I can do. If possible, please provide a screenshot of benchmark results from HD Tune or CrystalDiskMark (or equivalent), which displays maximum sustained read speeds performed by a blank drive; mentioning the physical weight (use a scale) of the HDD(s) in question is also highly encouraged.

Note 2: The new helium-based HDDs basically all employ seven or more platters and fourteen or more read/write heads. The main point of incorporating helium is to enable such huge amounts of platters and heads to be used, in order to get around the apparent limits (six platters and twelve heads, as of Q2 2016) of "fresh air-breathing" drives. For that reason, I will not be adding these helium-based HDDs to the lists.

Note 3: For a while between Q4 2017 and Q1 2018, this site was set to "private mode" in Blogger's settings, thereby completely cutting off public access. This was because I was planning to move the site to a more robust and better-organized content system. That fell through, so the site is now back to "public mode", as it was before. Apologies from yours truly for any inconvenience this may have caused.

Here are all of the models currently in the database for this manufacturer. 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 3.5" form-factor except when tagged otherwise.

A part of Quantum's model numbers that is (as far as I know) not relevant to platter density is blanked out with 'x's throughout this section; for example, the Pioneer SG "1.0AT SG10A011" is listed as "1.0AT SG10Axxx". There is no consistent pattern that I know of to these three alphanumeric characters, other than that models sold as part of PCs by the big makers (Dell, Compaq, etc) use different characters compared to "vanilla" units sold by distributors.

Quantum's HDD department was bought out by Maxtor in 2001; this is another page on the site featuring only super old models. Certain Maxtor model families (including the popular D740X-6L) that arrived after the Quantum acquisition, which physically resemble Quantum designs, can be found in the Maxtor page.

Note: Quantum's HDD department was bought out by Maxtor in 2001. Products with 40GB platters that were seemingly already in the pipeline turned up (with Maxtor badging on an obviously Quantum-flavoured HDA; how many and what other changes there were, other than ATA-133, are difficult to know) as the DiamondMax D540X-4K and Plus D740X families, listed on the Maxtor page.

Here are all of the models currently in the database for this manufacturer. 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.

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.

Maxtor drives went out of production before 2007, but as I like the idea of this site being about HDD history along with about platter capacity, this Maxtor page exists.

Maxtors of the DiamondMax 20~23 sequence are actually Seagate designs, and can be found on the Seagate 3.5" page.

Note 2: Very common as part of inexpensive desktop PCs sold between 2003~2006 (along with the RoHS-compliant version, which arrived towards the end of 2005). The usual recipe was: one of these drives loaded with Windows XP Home, a LG optical drive, a Netburst-era Celeron or K7-based Sempron, a mATX motherboard from ECS or ASRock, 256MB of RAM, integrated video/audio/LAN, and a brandless, flimsy, beige mid-tower case, complete with its included featherweight power supply. Bundle deals with CRT monitors and (incredibly cheaply-made) keyboards and mice were not uncommon.

Subsequent DiamondMax lines (21, 22, etc) are actually just Seagate Barracudas with the Maxtor logo on; as such, check the Seagate 3.5" list for those models.

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 3.5" form-factor except when tagged otherwise.

Though WD was never to be a serious contender in the enterprise above-7200RPM market, their various Raptors did the unique and offered a magical five-figure number through a SATA cable: effectively enterprise performance (or what could be mustered of it within the limitations) made more accessible to Joe Sixpack's gaming rig, and a thick layer of public prestige bestowed onto the letters "W" and "D" in sequence (or so their PR department would hope). Later versions aped the evolution of enterprise drives, shrinking to 2.5" (the VelociRaptors), and fielded with SAS connectors (the S25 and XE), with the latter pursuing even a sliver of a thumbnail in the real server iron pie, but any plans for 15K (undoubtedly the subject of wishful thinking in many comments sections) were surely scuttled by the rapid rise of SSDs.

37-40GB/platter Section (all drives under here use platters that can hold 37 or 40GB of data apiece.)

Raptor (1st-Gen) (10,000RPM, 8MB cache, SATA-150 interface)

WD360GD-xxFNAx/xxGHAx 37GB (1/2)

Note: Noticeably noisy at idle due to a ball-bearing spindle. All forthcoming Raptors would replace these with FDBs.

Raptor (2nd-Gen) (10,000RPM, 8MB cache, SATA-150 interface)

WD1500AHFD-xxRARx 150GB (2/4)

Note: This is a special version of the WD1500ADFD with a clear plastic window built into the lid. Perhaps needless to say, it was a staple in various looks-heavy "gaming" PC builds throughout 2006~2008.

Assume that all models are 9.5mm-thick except when tagged otherwise.

WD's AV-25 (later just AV, and eventually the unmarketed "Connected Home") is meant for DVRs, game consoles, and other such non-PC applications. The Reds use "NAS-worthy" firmware and are similar in targeted purpose as their 3.5" counterparts. The Green mark was applied for a period before 2015 to laptop-unfriendly Blues thicker than 9.5mm; these pursue non-specialized highest possible capacity in the 2.5" size. (Other Blues are listed in their own section.) This list also covers various 2.5" "Not For Resale" WD drives with and without soldered USB interfaces, which lurk inside some of the firm's external HDD products.

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.

The Scorpio (later Scorpio Blue, and then just Blue) and Scorpio Black (eventually just Black) are WD's primary mobile HDD lineups, rotating at 5400 and 7200RPM, respectively. These and various hybrid SSHD models are covered on this page. Niche 2.5" models intended for DVRs, NAS, with z-heights over 9.5mm, and/or with soldered USB connectors are in the other section.

Note: An HDD with an SSD bolted on, basically. The HDD part is likely based on the Blue WD10SPCX, with the SSD's PCB increasing the overall thickness to ~9.5mm. Special on-board logic means that, after installing the software, the two components show up as individual volumes to the host OS, in contrast to the self-contained "native" caching SSHDs sold by WD and the other makers.
