Seagate Exos 7E10: Standard, SED and FIPS Part Numbers, Data Sheet and UK Prices

Exos 7E10 prices on Amazon.co.uk

This table holds 8 listings right now. Lowest price per TB: £37.74/TB, pounds sterling inc VAT. The table covers every 7E10 capacity we track, from 2 TB to 10 TB, new and used together, with the part number on each row so you can match it to the sheet below.

Check the interface against the part number rather than the title. Seagate's sheet gives the SATA models 6.0, 3.0 and 1.5 Gb/s and the SAS models 12.0, 6.0 and 3.0 Gb/s, so a title that gives only 6GB/s does not tell you which interface you are buying. The part number tables below settle it.

Exos 7E10 part numbers: 2TB, 4TB, 6TB, 8TB and 10TB in SATA and SAS

The 7E10 sheet, DS1957.6M-2104US, prints six standard-model tables: three sector formats, each in SATA and SAS. Every standard number ends in B, and the three digits before the B carry the interface and the format:

The 512n tables cover 6, 4 and 2 TB; 8 TB and 10 TB appear only in the 512e/4KN and 4Kn tables. So at 4 TB alone there are six standard 7E10 drives, and a listing that says only Exos 7E10 4TB could be any of them. If your controller or software expects one format, match the number before price.

SED, SED-FIPS and PowerBalance: the other 7E10 numbers

Each of the six tables also carries Seagate Secure self-encrypting (SED) models, and most carry SED-FIPS 140-3 models. These are the numbers the sheet prints:

• PowerBalance, 512e/4KN SATA: ST10000NM025B, ST8000NM025B and ST6000NM027B at 10, 8 and 6 TB. The 4 TB and 2 TB cells are dashes.
• The 512n tables print no SED entry at 6 TB. Where SED-FIPS models are printed, none goes below 4 TB, and the 4Kn SATA SED-FIPS row is empty.

The same digits mean different drives at different sizes. ST10000NM021B is a 512e/4KN SATA SED-FIPS model, but ST6000NM021B is a 512e/4KN SATA SED model; ST10000NM011B is a 4Kn SAS SED-FIPS model, but ST4000NM011B is a 4Kn SAS SED model. Match the whole number, capacity included. The sheet adds a footnote that not all models will be generally offered as standard configurations, so a number on the sheet is not a promise that the drive is on sale anywhere.

Exos 7E10 datasheet figures: idle power and transfer by capacity

Two things stand out. First, the 512n tables are slower than the 512e/4KN ones at the same capacity: 215MB/s on 512n SATA against 250MB/s at 6 TB and 4 TB on 512e/4KN. Second, idle power is not fixed by capacity alone. At 6 TB the 4Kn SATA table states 6.04 W, against 7.06 W on the 512e/4KN SATA table, and at 6 TB the 512e/4KN SAS model is stated below its SATA twin. Read the row for your exact number rather than assuming one figure per size.

• Spindle speed 7,200 rpm, average latency 4.16 ms, 256MB multisegmented cache.
• MTBF 2,000,000 hours and an annualised failure rate of 0.44% at full 24x7 operation.
• Supported workload 550TB a year, and a 5-year limited warranty on the sheet.
• Weight on the 512e SATA table: 720 g at 10 TB, 716 g at 8 TB and 6 TB, 620 g at 4 TB and 2 TB.
• SATA models: 6.0, 3.0 and 1.5 Gb/s, single port, a dash for T10 DIF. SAS models: 12.0, 6.0 and 3.0 Gb/s, dual port, T10 DIF Yes.
• Logical sector size: 512 bytes on 512n and 512e/4KN SATA, 512, 520 or 528 on 512e/4KN SAS, 4,096 on 4Kn SATA, and 4,096, 4,160 or 4,224 on 4Kn SAS.

The 5-year limited warranty is Seagate's statement on its sheet, and its support page lists each model the same way, for example the 10 TB ST10000NM017B and the 2 TB ST2000NM000B. What a particular seller passes on with a listing is a separate question, so read the listing as well.

Is the Exos 7E10 CMR?

We cannot tell you. We have not found a CMR, SMR or helium row on the 7E10 sheet, nor any other Seagate document that states the 7E10's recording technology. The older 7E8 sheet does say CMR, describing the drive as built on field-proven 9th-generation conventional magnetic recording technology, but that is a statement about the 7E8, not its successor. The recording column in the tables on this page follows the same rule and shows CMR only where a document names the part number.

Exos 7E10 vs 7E8

The 7E8 sheet's tables top out at 8 TB, while the 7E10 supports up to 10 TB. Both sheets state 2 million hours MTBF and a 550TB a year workload, so on those two figures nothing changed. The part numbers did: 7E8 base models end in a digit, such as ST8000NM0055 for 8 TB SATA 512e, ST8000NM0075 for SAS 512e, ST8000NM0045 for 4Kn SATA and ST8000NM0065 for 4Kn SAS. None carries the 7E10's B suffix.

At 8 TB the 7E10 is both the faster and the more frugal drive on paper. At 6 TB it is faster but idles higher in SATA, while in SAS it idles well below the 7E8. If you are replacing a 7E8 in an array, the 7E10 at the same capacity is a newer model with different figures, not the same drive.

Exos 7E10 vs X18 and the helium X10

The X18 and the 7E10 do not share a capacity. The X18 sheet starts at 12 TB, where the 7E10 ends at 10 TB, and it describes a helium sealed-drive design with CMR. Its 12 TB SATA model, ST12000NM000J, is stated at 4.4 W idle and 270MB/s, against 7.8 W and 263MB/s for the 10 TB 7E10 512e/4KN SATA model. By our division that is about 0.37 W/TB for the X18 against 0.78 W/TB for the 7E10.

The X10 overlaps the 7E10 at 8 TB and 10 TB. Its sheet describes a helium-sealed design and states 2.5 million hours MTBF, against 2 million on the 7E10. Its SATA models idle at 4.5 W (hyperscale) or 5 W (standard), against 7.06 W for the 8 TB 7E10 512e SATA model. If idle power over years matters more than the newest part number, those figures favour the helium drives. For larger capacities, see Exos X18.

Exos 7E10 datasheet: which document to read

The family's own sheet is DS1957.6M-2104US, the source for every table on this page. Seagate's December 2025 portfolio sheet, DS2046.1-2512, prints all six B-suffix tables, 512e/4KN, 4Kn and 512n in both SATA and SAS, under the heading Exos; we have not found the 7E10 name on it. So a listing that cites only that newer sheet is still describing these drives, whatever the format.

For buying by capacity rather than by family, with other makers in the same table, see 4TB enterprise hard drives, 8TB enterprise hard drives and 10TB enterprise hard drives. The same numbers appear by interface on Seagate Exos SATA and Seagate Exos SAS.

Across the new and used tables: 7 listings in new condition and 3 listings in used condition. A used 7E10 is a seller's used drive; condition is stated on each row.
