Samsung PM893 SATA SSD: Part Numbers, Endurance, Speed by Capacity and UK Prices

Samsung PM893 part numbers: 240GB, 480GB, 960GB, 1.92TB, 3.84TB and 7.68TB

Samsung's PM893 data sheet, Revision 1.0, is marked as the initial release of August 2022. It gives each of the six capacities its own part number, and on the sheet all six end in -00W07.

The sheet also prints shorter model codes, such as MZ-7L396000 for the 960GB and MZ-7L31T900 for the 1.92TB, so a listing may name either form.

Listings on Amazon.co.uk do not always match the sheet's strings. Some of the PM893 listings we track end in -00A07 at 3.84TB and 7.68TB, and others print no suffix at all. We have not found a Samsung document explaining the -00A07 ending, so we treat it neither as a separate variant nor as proof of the same drive: ask the seller what it denotes. The MZ7L3 stem and the capacity code are the parts the sheet does let you check.

Two near names turn up beside the PM893: the PM897 and the PM863. Neither is a PM893, and the table below leaves both out. One PM897 listing prints MZ7L3960HBLT, which shares its first nine characters with the PM893 960GB's MZ7L3960HCJR, so read the whole string rather than the start of it.

Samsung PM893 speed by capacity

From 960GB up the speed rows are identical, so on performance the only decision is whether to go below 960GB. The 240GB is the outlier: 380 MB/s sequential write and roughly half the 480GB's random write. Random write is the PM893's weaker figure throughout, 30K IOPS at best against 98K for random read, so on this measure the drive reads more than three times as fast as it writes.

Samsung PM893 endurance and the TBW warranty limit

Samsung rates endurance in terabytes written, from 438TB at 240GB, doubling with each capacity step to 14,016TB at 7.68TB. Divided by the capacity, 365 days and 5 years, every size works out at one drive write per day. That is our arithmetic: the sheet prints no DWPD label and no read-intensive or mixed-use class.

The warranty is 5 years limited, and the sheet adds that it covers the stated time period or the TBW, whichever comes first. On a heavily written drive, then, the terabytes may end cover before the calendar does. By our arithmetic a 240GB rewritten twice a day would reach its 438TB in about two and a half years.

We have not found a Samsung document stating how that warranty applies to a drive bought from a particular seller on Amazon.co.uk, so ask the seller before you buy.

Samsung PM893 encryption, power and temperature

The sheet lists AES 256-bit full disk encryption, TCG/Opal V2.0 and Encrypted Drive (IEEE1667) support, and it gives one part number per capacity rather than a separate encrypted model.

• Idle power 1.5 W with DIPM off, the same across the range.
• Active read / write power: 2.1 / 2.7 W at 240GB, 2.1 / 3.2 W at 480GB, and 2.2 / 3.2 W from 960GB up.
• Operating temperature 0 °C to 70 °C.
• MTBF 2.0 million hours.
• NAND and controller: Samsung V-NAND TLC with a Samsung in-house controller.

We have not found a power loss protection statement in Samsung's PM893 data sheet. If your use depends on it, ask for a Samsung document that states it, rather than relying on a listing title.

Samsung labels capacity in decimal gigabytes, 1GB being 1,000,000,000 bytes, and notes that usable capacity may be less than the labelled figure.

Samsung PM893 price on Amazon.co.uk

The table holds 1 listing right now. Prices are pounds sterling inc VAT, sorted per TB, and each row shows whether it is new or used. A title may write the capacity oddly, such as 7.680GB for the 7.68TB, so go by the part number and the sheet's capacity list.

The enterprise SSD page sets SATA beside SAS and NVMe. The Samsung PM9A3 page covers a Samsung NVMe drive, and the 3.84TB SSD and 7.68TB SSD pages compare those sizes across makers and interfaces.

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.
