| Availability: | In Stock |
The HPE 833928-B21 is a 4TB large form factor hard drive built for servers that hold their 3.5in disks in low profile bays rather than hot-plug SmartCarrier trays. It connects over 12Gb/s SAS, spins at 7,200 RPM and runs digitally signed HPE firmware. HPE first sold it as a Midline drive and now lists the same option under its Business Critical label.
This drive suits IT teams running tower servers such as the HPE ProLiant ML350 Gen10, plus storage builds that need plenty of affordable capacity per bay. Typical jobs include file shares, backup targets, archive volumes and video retention, where cost per terabyte matters more than raw random speed.
Euroland IT Store offers the 833928-B21 in New and Refurbished condition, subject to current stock.

833928-B21 is the HPE option kit number, the code used when the drive is ordered as an upgrade or add-on. When an HPE engineer replaces the same drive under service, the part that turns up is spare 834134-001. HPE PartSurfer ties the two numbers together and describes the spare as a 4TB SAS 12Gb/s, 7,200 RPM, 3.5in Midline drive in low profile form.
The exact number matters because HPE sells 4TB SAS drives in more than one mounting style. A low profile drive and a SmartCarrier drive may share capacity and speed yet still fit different bays. Ordering by option or spare number avoids a drive that arrives with the wrong mounting for your chassis.
Low profile drives are designed for non-hot-plug cages, where the disk sits on rails or in a simple bracket and is cabled or plugged into a fixed backplane. To swap one, you shut the server down first. That trade-off keeps entry and tower systems simpler and cheaper to build.
SmartCarrier drives, by contrast, live in hot-plug trays with status LEDs and a release lever. They slot into the front bays of rack servers and can be changed while the system runs. If your server uses SC trays, an LP drive such as the 833928-B21 is not the right choice, so look at the bay type before you order.
Midline duty is another point to note. These drives are aimed at capacity work with moderate daily load. They are a sensible fit for bulk data but are not intended to replace 10K or 15K Enterprise drives in heavy transactional systems.
A New 833928-B21 is a good choice when you are building a fresh array, extending a project under strict sourcing rules, or simply prefer a drive with no prior run time. Check the product page for the exact condition notes and the warranty offered at the time you buy.
Refurbished units help when you need to match drives already in service or keep an older ML350 running at lower cost. They are often chosen by repairers and support teams who need a like-for-like replacement quickly. The warranty and condition for refurbished stock are shown on the product page, so read those details before ordering.
HPE PartSurfer lists spare 834134-001 in these product lines:
Before you place an order, read the label on the drive you are replacing and confirm your server model and storage controller. A 12G SAS drive needs a SAS capable controller; it will not run from a SATA only port.
The other 4TB numbers above may use a different carrier, so compare the mounting style before treating any of them as a direct swap. You can also browse the wider server hard drive range.
Because this drive sits in a low profile bay, a replacement means a planned shutdown. Schedule the work out of hours, confirm you have a recent backup, and record which bay holds the failed disk. Once the new drive is fitted and the server is back up, the Smart Array controller should start rebuilding the logical drive. Leave the rebuild to finish before adding new load, as a large 4TB rebuild can take several hours.

No, it is a low profile drive for non-hot-plug bays, so the server must be powered down before it is fitted or removed.
New suits fresh builds and projects with strict sourcing rules, while Refurbished is a lower cost way to match drives already in service.
