DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic Random Access Memory) and DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) are types of memory used in computers.
DDR3 and DDR4 have some similarities, such as being double data rate and synchronous, but they also have some key differences.
DDR3 has a lower clock speed, typically ranging from 800 MHz to 1600 MHz, while DDR4 has a higher clock speed, typically ranging from 1600 MHz to 3200 MHz. This means that DDR4 can transfer data faster than DDR3.
DDR3 has a lower voltage, typically 1.5 volts, while DDR4 has a higher voltage, typically 1.2 volts. This means that DDR4 is more power efficient than DDR3.
DDR3 has a lower maximum capacity, typically 16GB per DIMM, while DDR4 has a higher maximum capacity, typically 64GB per DIMM.
DDR3 SDRAM is no longer being manufactured as DDR4 is now the standard for new systems, so DDR4 is considered as an upgrade over DDR3.
ECC Registered FeatureECC (Error-Correcting Code) Registered is a feature that is commonly found in DDR3 and DDR4 memory modules. It is a type of memory that includes additional memory chips for the purpose of detecting and correcting errors that may occur in the memory.
ECC memory uses a special algorithm to detect and correct single-bit errors that may occur in the memory. This is done by adding extra bits to the memory, called parity bits, which are used to detect and correct errors.
ECC Registered memory is a type of ECC memory that also includes a register between the memory controller and the memory chips. This register acts as a buffer, allowing the memory controller to communicate with the memory chips more efficiently.
ECC Registered memory is typically used in servers and high-end workstations, where data integrity and reliability are critical. It is considered more reliable than non-ECC memory, as it can detect and correct errors that may otherwise go unnoticed.
ECC memory is more expensive than non-ECC memory and also has a slight performance overhead due to the additional parity bits, but it is considered to be more reliable, especially for data-sensitive applications.
High-Capacity StorageHigh-capacity storage refers to the ability to store large amounts of data on a single device. This can be achieved through various types of storage technology, such as hard disk drives (HDD), solid-state drives (SSD), and tape drives.
HDDs are traditional spinning disk drives that have been around for decades. They offer large storage capacities at a relatively low cost and are commonly used in desktop computers and external storage devices. However, HDDs are slower than SSDs and are more susceptible to damage from physical shocks.
SSDs are newer storage technology that use flash memory to store data. They are faster than HDDs, have no moving parts, and are more resistant to physical shocks. However, SSDs are more expensive than HDDs and typically have lower storage capacities.
Tape drives are a type of storage that use magnetic tape to store data. They are mainly used for archiving large amounts of data and can store several terabytes of data on a single tape cartridge. Tape drives are slower than HDDs and SSDs, but they are more cost-effective for long-term storage.
High-capacity storage can also be achieved through the use of storage arrays, which are systems that can combine multiple hard drives into a single large storage pool. This allows for the creation of large storage volumes and enables data to be stored and accessed more efficiently.

Warranty
ALLHDD guarantees that the products will not have defects in material that will affect the product's functionality during the Standard Warranty Period. The warranty period starts when the merchandise/items from our warehouse.
What does ALLHDD.Com warranty cover?
30-days to 3 years warranty:
Replacement or refund. In the case of material defects, we will try to replace the product first. The product will be replaced before the expiration of the original warranty. For any failure of hardware, if we cannot process the replacement of the product(s)/model(s), we will refund the original selling/invoiced price. The shipping costs and sales tax, if any, are non-refundable. ALLHDD retains the right to decide whether the item(s) will process for replacement or refund.
What is not covered by our warranty?
The reason why our warranty does not cover any problem caused by the following conditions:
(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;
(b) any misuse outside the instructions in the user manual for any specific product;
(c) damaged caused by other hardware or equipment. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
Final Sale items are non-returnable/refundable in any situation. Any question? please ask our team before the shipment.
