Toshiba MG08: Every Part Number, MG08ACA16TE to MG08ADA800E, With Specs and Prices

Toshiba MG08ACA16TE and the other MG08 part numbers at 16 TB and 14 TB

The MG08 overview prints its part numbers in the header of the specification table, with no separate model table. This grid joins the SATA-3.3 columns to the SAS-3.0 columns, row by row. Numbers ending A or AY are 4Kn, and numbers ending E or EY are 512e. MG08ACA16TE is therefore the 16 TB SATA 512e number, and MG08SCA16TE is its SAS counterpart.

Two things here catch people out. The ACP and SCP forms appear only at 16 TB in this document, so we cannot point to a 14 TB number of that kind. And the letters are unexplained. The overview offers SIE and SED option models, an instant-erase option and a self-encrypting drive, but we have not found a line in it that ties the Y or the P to either one. That is why the rows above keep their letters. Do not carry a meaning across from another generation's table.

The 16 TB SATA table holds 1 listing right now. Lowest per TB: £23.04/TB. Match each row's part number against the grid, since TA, TE and TEY are different numbers at the same size.

Toshiba MG08 specifications: SATA and SAS side by side

Toshiba describes MG08 as 16 TB and 14 TB of conventional magnetic recording (CMR) at 7200 rpm, in a 9-disk helium-sealed design. It calls that design industry-leading in a footnote dated January 2019, so read the phrase as a claim of its time. The two interfaces share most of their figures.

Power is where this overview stops short. It prints one pair of values per interface across columns for two capacities. From the extracted text we cannot prove whether each value covers both 16 TB and 14 TB or only 16 TB. So we assign none of them to a capacity, and we give no W/TB figure. What we can say is that SAS reads 0.49 W higher on write/read and 0.46 W higher at idle in the same table position. That subtraction is ours.

Settle the sector format before you order. The overview prints no 528 B format for MG08, so check it if your controller expects one. Toshiba says 512e models include its Persistent Write Cache technology for data-loss protection in sudden power loss. Whether a given host accepts 4Kn or 512e is for you to confirm; the overview makes no statement about a particular machine.

The MTTF and AFR are ratings with conditions attached: 8760 power-on hours a year, up to 550 TB a year, and an average HDA surface temperature of 40 °C or less. A footnote adds that use above that temperature 'may degrade product reliability and reduce warranty period'. Compare that line with what your enclosure reports. The document is Rev. 03, July 2021.

Toshiba MG08ADA800E and the MG08-D line at 8, 6 and 4 TB

MG08ADA800E is in a different document. The MG08-D overview covers 8, 6 and 4 TB, with SATA-3.3 numbers (MG08ADA, MG08ADP) and dual-port SAS-3 numbers (MG08SDA, MG08SDP). A direct fetch of Toshiba's PDF returned nothing readable, so we read it through a reader. Treat this grid as a transcription, and confirm a number before you rely on it.

Only the 4 TB rows carry 512n numbers, on both interfaces. The table as we read it does not map Y or P to SIE or SED, so those letters stay as labels. The P rows came through the reader without a sector label of their own, which is why we name their last letter and stop there.

So the two lines share a name and not a specification. An MG08-D has half the buffer of an MG08 and a lower rated MTTF, at the same workload rating. The MG08-D document prints per-capacity power as well; we have left those cells out, because we have not confirmed this transcription against the PDF, and the same caution applies to the MG08-D figures above. The extract states no recording technology for MG08-D, so we state none, and the CMR wording in the MG08 overview does not carry over. We also hold no weight for this line. The document is Rev. 01, copyright 2020.

MG08ACA16TA, MG08ACA16TE and MG08ACA16TEY in Backblaze's fleet

Same capacity, same interface, three suffixes, and one of them stands apart. MG08ACA16TEY shows 3.66% for the quarter and 2.43% over its lifetime, against 1.03% and 1.23% for MG08ACA16TE. The two are close in age at 53.5 and 51.4 months, so age alone does not separate them. We cannot say what does. This is one operator's fleet in its own data centres, and it does not show that the Y itself is the cause.

MG08ACA16TA is younger, at 33.7 months, so its 1.01% is not like for like with the other two. Backblaze counts a model only above a minimum size, 100 drives and 10,000 drive days for the quarter and 500 drives and 100,000 drive days for lifetime. These three rows are all it has for MG08, so it says nothing about a 14 TB, SAS or MG08-D drive. Toshiba's 0.35% is a rating under stated conditions and Backblaze's figures are field counts, so the two are different measures.

Toshiba MG08 prices on Amazon.co.uk

The table below holds 1 listing right now. That includes 1 listing in new condition. Lowest per TB: £23.04/TB. Lowest outlay: £368.59. Prices are pounds sterling inc VAT and the sort is per TB, which is a price order and nothing more.

The filter relies on the generation our catalogue reads from a listing, so a listing with a generic title can fall outside it. Sellers write their own titles, which is why the part number decides what a row is. If a listing gives no number, ask for it before you press Buy on Amazon. Other makers at these sizes are on 16 TB enterprise hard drives, 14 TB enterprise hard drives and 8 TB enterprise hard drives. SAS at 16 TB has its own page, 16 TB SAS hard drives.

We have found no warranty length in the MG08 overview; its only mention is the temperature footnote above. Toshiba Europe's MG Series page says "The MG Series comes with a 5-year limited warranty" and elsewhere "A 5-year extended warranty is also included", and that the warranty commitments "apply under the assumption that annual workload does not exceed 550 TB". Its range table, as extracted, lists no MG07 or MG08 prefix, so we cannot tell whether that reaches those generations. Neither does the page say how a particular seller or a used unit is treated. None of this shows that MG08 has ended, only what that table lists.

In-stock alternatives

None of these is the product this page covers: they are what is in stock on Amazon.co.uk beside it right now. Each row says why it is listed. Check the interface, form factor and part number against your system before buying.
