ST3 means SATA3

250 means 250g

3 means 8mb cache (2 to the power of 3 equals 8). 10 means that the number of discs is 1

ST Yes Interface Type is SATA 3 is 3 inches size 250 Yes Capacity 318s is the current firmware serial number.

It is the model of the hard disk, and it is preliminarily judged to be a Seagate 3-inch 250G 8M cache serial port.

The Seagate ST3500418AS is not an SSD. It's an HDD.

The Seagate ST3500418AS hard drive belongs to the Barracuda series of hard drives launched by Seagate Technology, which has reached a single disk capacity of 500G for the first time.

Because each number of a hard drive represents a specific meaning, for us consumers, the hard drive number is like the "ID card" of the hard drive. Through these complex numbers, we can interpret the capacity, speed, interface type, cache and other performance indicators of the hard disk, and this information is very helpful for us to choose our favorite hard disk products.

It's a pity that it's a mechanical hard drive.

The Barracuda series of desktop hard drives are fully equipped with single-disk 500GB technology, with a capacity density of 329GB per square inch, and a total capacity of 500GB, 750GB and 1TB.

The models of these three hard disks are "ST3500418AS", "ST3750528AS", and "ST31000528AS", where the penultimate character represents the number of discs, that is, the 500GB model is a single disc, 20mm thick, and weighs 540 grams, and the 750GB 1TB model is a double disc, thick mm, and weighs 640 grams.

In terms of specifications, the Barracuda series all use SATA 3Gbps interface, 7200RPM, support NCQ technology, stable data transfer rate of 160MB S, cache 16MB (500GB) or 32MB (750GB 1TB), average latency, random read seek time is less than, random write seek time is less than, average power consumption seek 12W, idle 8W, noise seek 28DBA, idle 27DBA, annual failure rate. The Seagate Single Drive 500G HDD is designed with an inverted PCB circuit board, so that the chips, components, etc. cannot be seen, which can avoid static electricity or collision damage to the hard drive.

Seagate also highlighted the environmental features of the drives, such as more than 70% of the manufacturing materials are recyclable and comply with EU RoHS standards.

ST3500418AS is a mechanical hard drive, ST: stands for Seagate.

3: Represents an inch hard disk.

500: indicates that the hard disk capacity is 500 GB

4: The number of caches of the hard disk is 16M (2 to the 4th power) 1: Represents 1 platter.

8: The version number, which may also correspond to the origin of AS: Serial ATA, that is, the SATA hard disk interface.

Solid state drives, referred to as solid state drives, are hard disks made of solid-state electronic memory chip arrays, which are composed of control units and storage units (flash chips, DRAM chips). SSDs are identical to HDDs in terms of interface specifications and definitions, functions and usage methods, and are also completely consistent with HDDs in terms of product shape and size.

Seagate hard drive model identification method.

Seagate hard disk model identification method Seagate hard disk number is relatively simple, its identification method is: "ST + hard disk size + capacity + primary identification + secondary identification + interface type".

First of all, "ST" stands for "Seagate", which means Seagate's products.

Then the "x" in the first part is to indicate its hard drive form factor and size. "1" represents inches, and the thickness of a full-height hard disk is 41mm; "3" indicates inches, and the thickness of a half-height hard drive is 25mm; "4" indicates inches, 82mm thick hard drives; "5" indicates a hard drive with a size of inches and a thickness of 19mm; "9" is the size of the hard drive in inches.

The four "Xs" in the second part indicate the capacity of the hard drive, which usually consists of 3 to 4 digits in GB. For example, "1600" means that the capacity of the hard disk is 160GB, and "400" or "800" means that the capacity is 40GB or 80GB.

The two "x" in the third part are the hard disk logo, which consists of the main logo and the secondary logo. The previous number is the main sign, in Seagate's IDE hard drives, it refers to the number of disks of the hard drive, such as the number "2" indicates that the hard drive uses 2 discs. In Seagate's SCSI hard drives, the main identifier refers to the rotational speed of the hard drive.

With the main logo, of course, there will be a secondary logo, and the last number is the secondary logo. It is only when the primary identity is the same or invalid that the secondary identity is meaningful. It generally represents the performance and generation of the hard drive, when the number is larger, the higher the number of generations, the better the performance, and the newer the hard drive.

The three "x" in the third part are mainly composed of 1 to 3 letters, indicating the type of hard disk interface, etc. Typical desktop IDE drives are simpler, but when you include current and early SCSI drives, the meaning becomes more complex.

A" indicates an interface for ATA UDMA 33 or UDMA 66 IDE.

as" is the interface of the Serial ATA150.

"ag" indicates the interface for ATA dedicated to laptops.

N" is the interface for 50-pin Ultra SCSI, which has a data transfer rate of 20MB s

"W" is a 68-pin Ultra SCSI interface with a data transfer rate of 40MB S

"WC" is an 80-pin Ultra SCSI interface.

FC" is an optical fiber that provides data rates of up to 100MB s and is hot-swappable.

"WD" denotes the 68-pin Ultra Wide SCSI interface.

"LW" is a 68-pin Ultra-2 SCSI (LVD) interface.

LC" is an 80-pin Ultra-2 SCSI (LVD) interface.

Seagate ST31000528 is your hard drive make model and capacity for these.

If there is a problem with your hard drive, and within the warranty period, you don't have to worry about the manufacturer giving you a bad hard drive, because the manufacturer will not do such a thing, if you change a bad hard disk, it can only be said that the merchant can do such a thing, and the manufacturer will not, the hard disk manufacturer will not do something because of a problem with a hard disk warranty period, you can rest assured, and you said that the serial number is not a problem, If you are given a touch of the same hard disk serial number is still your current bad hard disk serial number, it means that this hard disk is for you to repair, after returning to the factory you get another serial number of the hard disk, indicating that people directly replaced you with a piece, the general delivery party will directly replace it, will not wait for the manufacturer to repair, so you can get a new hard disk, isn't it better, so your worries are unnecessary worries, these hard disk brands will not return to the factory a bad hard disk, and then give you a bad hard disk, Generally for a new one,And the serial number of this thing on a fixed number,The country can't find the second one touch the same serial number,If you can find it, it means it's fake,If you ask for this serial number of the hard disk, you can only get it after the repair,And it's very difficult to achieve this,The hard disk repaired by the manufacturer so many people won't give you a special record of what hard disk to do alone,There are even some that can't be repaired,Or not repaired at all,Directly replace the hard disk。

It's almost unrealistic to return a bad hard disk to the factory, and the 1T hard disk has not been discontinued, so can you miss this hard disk? So far, I haven't heard of a bad hard disk returned to the factory, a bad hard disk is returned, the motherboard or graphics card often happens, it is a bad return to the factory back a good product (during the warranty period, discontinued, but back is a good motherboard or graphics card, but not new) hard disk is no problem, as long as it is in the warranty, it will not happen, even if it is discontinued, there will be a solution, rest assured, your hard disk worries are unnecessary, good luck!

ST: Seagate; 3: Thick plate of the machine; 1000: 1g capacity; 5:32M Cache; 2: double disc; 8: Batch number.

The inspector is **? Pure to you.

The real return to the factory hard drive is definitely not this disk, giving you a spare disk, good performance. The serial number or something must have changed.

The performance of the hard disk should be the same or only high but not low, if it is low, it is the hard disk manufacturer that replaced it for you.

The hard drive dealer may return it to the factory, or repair or replace it yourself. It is better to ask for a return to the factory, but it is very long, at least 2 months.

Your hard drive is SATA2 interface, if you really return to the factory, it is likely to be SATA3, because the old hard drive is almost gone.

You look at it and hope it can help you.

It's impossible to change to a worse one, the manufacturer will not affect the company's reputation for a hard drive, only the sales will engage in these small actions, but now they generally dare not do this.

The identification method is: "ST + hard disk size + capacity + primary ID + secondary ID + interface type".

For example, your hard drive ST indicates that it is WestJet. The first number 3 represents inches, a half-height hard drive with a thickness of 25mm, 250 means 250g, 3 means 3 platters, 10 means 10000 rpm, and "as" represents the interface of serial ata150.

Part 1: Consists of two English letters, which are the Seagate logo;

Part II: Consists of a letter representing the external dimensions:

1 represents inch width, inch height;

3 represents inch width, 1 inch height;

Part 3: Composed of five letters, representing the standard capacity unit MBThe fourth part: Composed of 1-3 English letters, representing the interface and the technology used.
